Heartbleed vulnerability explanation

The Heartbleed vulnerability is a security flaw that was discovered in 2014 within the OpenSSL cryptography library, affecting the widely used Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. This vulnerability potentially allowed attackers to access private information such as usernames, passwords, and other sensitive data transmitted over the internet.

The flaw was a result of a missing bounds check in the implementation of the TLS heartbeat extension, hence the name "Heartbleed." By sending a specially crafted heartbeat request to a vulnerable server, an attacker could trick the server into returning more data than it should, including data stored in the server's memory.

The impact of the Heartbleed vulnerability was widespread, as OpenSSL is one of the most popular open-source encryption libraries used to secure internet communication. Many websites and online services were affected, and individuals were urged to change their passwords on vulnerable sites once servers were patched.

What are the Main Types of Security Vulnerabilities When Working With Open Source Components? - Technology Org

The vulnerabilities inherent in open-source components warrant due consideration, given their potential threats. As we work to unravel the primary security risks associated with open-source components, particularly in software development, we will present viable solutions for mitigating these risks. While open-source software can benefit the rapid development of systems, it also exposes projects to innate security risks. This is true, particularly if they are managed incorrectly. A detailed understanding of the security vulnerabilities is sacrosanct.

Artificial intelligence (AI) – artistic interpretation. Image credit: Pixabay, free license

Nowadays, open-source components, as part of software development, are indispensable. Widespread use has led to increased exposure to security flaws. Many instances exist, notably the Heartbleed bug in OpenSSL and the gaping vulnerabilities in ApacheLog4J. Both of these examples highlight the critical nature of safe and secure operations with open-source libraries. These vulnerabilities compromised millions of systems worldwide, ensuring that vigilance becomes a top priority within the open-source ecosystem.

For example, Synopsys Cybersecurity Research Centre discovered that 84% of companies are vulnerable to open-source code in their systems. This is especially true with JavaScript – the most widely used code framework. The report was based on 1700 audits and 17 industries globally, and it revealed that at least one known open-source vulnerability existed in the code bases. That statistic was 4% higher than the previous year.

Unknown Source Code Quality

Quality is not a blanket standard. It varies between systems, processes, and software applications. Therefore, the quality of open-source code varies widely. Without thorough vetting, it can be disingenuous to incorporate open-source components with poorly written code, unoptimized code, or gaping holes in the security infrastructure. Setting a standard, raising the benchmark of excellence, and enforcing compliance across the board is imperative.

Risks Associated with Licensing

One has to walk a fine line between understanding security vulnerabilities, and the legal aspects that may impact the viability and sustainability of a project. License risks are not a direct security threat, but misuse or abuse of open-source licenses can result in legal challenges and disputes. These will indirectly impact the security of projects underway.

Insecure Dependency Risk

Many open-source projects rely on various open-source frameworks and libraries. As expected, the absence of standards can result in introduced vulnerabilities. To maintain excellence, regular updates are imperative. By the same token, all security-related issues must be promptly addressed and corrected.

Ineffectual Security Practices in Development

The design and development stage of open-source software and projects is often mired in security practices. This is especially true if these projects do not follow rigorous security protocols. This can lead to clearing vulnerabilities, including cross-site scripting (XSS), SQL injections, or even cross-site request forgery (CSRF). If any of these, where similar vulnerabilities are introduced into the open source projects, they can pose tremendous challenges.

Insufficient Documentation and Updating

Open source components invariably suffer from inadequate documentation vis-a-vis security practices. Similarly, they may lack timely updates for known vulnerabilities. These loopholes present gateways for nefarious actors, allowing infiltration and disruption of systems. Once exposed, the open-source software is highly vulnerable to attack. Security flaws must be identified, addressed, and corrected as quickly as possible.

Fortunately, the features and benefits of software security tools like Checkmarx Static Application Security Testing (SAST) can provide relief for these exigencies. Companies no longer have to choose between scanning code quickly for security vulnerabilities and completing a thorough review of the open-source components. SAST offers a viable solution in terms of comprehensive security oversight and rapid assessment during developmental processes.

The key features of such breakthrough technology include a mix of elements, notably:

The best fix location

Rapid scanning for vulnerabilities

Ability to scan uncompiled open-source code

Artificial Intelligence query builder and security

Full support in multiple languages and across frameworks

Viewed in perspective, such solutions place the developers in control by reducing noise and finalizing secure code in the software and systems. A credible and trusted security solution makes application development efficient and secure. This balances the need for speed and security. Since it’s also developer-friendly, it easily integrates into work environments and with tools developers already use.

To the uninitiated, these types of tech solutions used for identifying security vulnerabilities, notably open-source components, are akin to using tools and resources that can rapidly identify errors and suggest a best-practice methodology to improve material based on relevance. That’s precisely what top-tier SAST does for software development. It secures code, ramps up the pace of development, and identifies problems as efficiently and effectively as possible.

Tor Browser: Anonymous?

With your normal browser, companies can track what you do and people can steal your IP addresses and find what you do. A kind of browser to fight this, called Tor, was released in 2002. It featured a way to mask the user’s identity, channelling traffic through a circuit called an Onion circuit. However, is it truly safe?

Tor is a network that attempts to conceal its users by encrypting packets, stripping part of their headers and bouncing them around an onion circuit. The only way to find out who sent it is through the unprotected exit nodes, which can be monitored by software.

Tor is most commonly used for illegal activities, such as trafficking and drug dealing, and also for torrents, which are websites for illegally downloading files.

However, BitTorrent (a torrenting website) and Tor do not work well together, and it’s possible for IP addresses to be extracted from extension protocol handshakes.

Also, Tor is vulnerable to man-in-the-middle attacks as well. Many people do not notice their encryption removed as they use Tor. We also have an error that still affects websites today. The Heartbleed OpenSSL bug exposed some security and Tor was required to renew many private keys, which are a component in cryptography.

What Makes Bitcoin So Volatile?

Traders are always concerned about 'Bitcoin''s volatility. It is important to know what makes the value of this particular digital currency highly unstable. Just like many other things, the value of 'Bitcoin' also depends upon the rules of demand and supply. If the demand for 'Bitcoin' increases, then the price will also increase. On the contrary side, the decrease in demand for the 'Bitcoin' will lead to decreased demand. In simple words, we can say that the price is determined by what amount the trading market is agreed to pay. If a large number of people wish to purchase 'Bitcoin's, then the price will rise. If more folks want to sell wallet development, then the price will come down.

It is worth knowing that the value of 'Bitcoin' can be volatile if compared to more established commodities and currencies. This fact can be credited to its comparatively small market size, which means that a lesser amount of money can shift the price of 'Bitcoin' more prominently. This inconsistency will reduce naturally over the passage of time as the currency develops and the market size grows.

After being teased in late 2016, 'Bitcoin' touched a new record high level in the first week of the current year. There could be several factors causing the 'Bitcoin' to be volatile. Some of these are discussed here.

The Bad Press Factor

'Bitcoin' users are mostly scared by different news events including the statements by government officials and geopolitical events that 'Bitcoin' can be possibly regulated. It means the rate of 'Bitcoin' adoption is troubled by negative or bad press reports. Different bad news stories created fear in investors and prohibited them from investing in this digital currency. An example of bad headline news is the eminent utilization of 'Bitcoin' in processing drug transactions through Silk Road which came to an end with the FBI stoppage of the market in October 2013. This sort of stories produced panic among people and caused the 'Bitcoin' value to decrease greatly. On the other side, veterans in the trading industry saw such negative incidents as an evidence that the 'Bitcoin' industry is maturing. So the 'Bitcoin' started to gain its increased value soon after the effect of bad press vanished.

Fluctuations of the Perceived Value

Another great reason for 'Bitcoin' value to become volatile is the fluctuation of the 'Bitcoin''s perceived value. You may know that this digital currency has properties akin to gold. This is ruled by a design decision by the makers of the core technology to restrict its production to a static amount, 21 million BTC. Due to this factor, investors may allocate less or more assets in into 'Bitcoin'.

News about Security Breaches

Various news agencies and digital media play an important role in building a negative or positive public concept. If you see something being advertised Advantageously, you are likely to go for that without paying much attention to negative sides. There has been news about 'Bitcoin' security breaches and it really made the investors think twice before investing their hard earned money in 'Bitcoin' trading. They become too susceptible about choosing any specific 'Bitcoin' investment platform. 'Bitcoin' may become volatile when 'Bitcoin' community uncovers security susceptibilities in an effort to create a great open source response in form of security fixes. Such security concerns give birth to several open-source software such as Linux. Therefore, it is advisable that 'Bitcoin' developers should expose security vulnerabilities to the general public in order to make strong solutions.

The latest 'OpenSSL' weaknesses attacked by 'Heartbleed' bug and reported by Neel Mehta (a member of Google's security team) on April 1, 2014, appear to had some descending effect on the value of 'Bitcoin'. According to some reports, the 'Bitcoin' value decreased up to 10% in the ensuing month as compared to the U.S. Dollar.

Small option value for holders of large 'Bitcoin' Proportions

The volatility of 'Bitcoin' also depends upon 'Bitcoin' holders having large proportions of this digital currency. It is not clear for 'Bitcoin' investors (with current holdings over $10M) that how they would settle a position that expands into a fiat position without moving the market severely. So 'Bitcoin' has not touched the bulk market adoption rates that would be important to give option value to large 'Bitcoin' holders.

Effects of Mt Gox

The recent high-profile damages at 'Mt Gox' are another great reason for the 'Bitcoin' volatility. All these losses and the resultant news about heavy losses had a dual effect on instability. You may not know that this reduced the general float of 'Bitcoin' by almost 5%. This also created a potential lift on the residual 'Bitcoin' value due to the reason of increased scarcity. Nevertheless, superseding this lift was the negative outcome of the news series that followed. Particularly, many other 'Bitcoin' gateways saw the large failure at Mt Gox as an optimistic thing for the long-term prospects of the 'Bitcoin'.

While setting up a rule to filter this particular email seems like a fairly easy fix, the malware hidden in the email message had a very low antivirus detection rate on VirusTotal, just two of 53 products detected the sample when Ullrich checked. “LogmeIn does publish a record, and the e-mail did not originate from a valid LogmeIn mail sender, so it should be easy to discriminate against these emails using a standard spam filter,” Ullrich explained. Another reason is that Ullrich at one point had a LogMeIn account established with the email address that received the malware-laden message. One of those reasons is that the email address behind the scam is appearing to originate from a legitimate, LogMeIn email account.

This attack stands out from the ceaseless torrent of spam emails that at times constitutes nearly 70 percent of global email traffic for a couple of reasons. Also in the email was a link to the actual LogMeIn website, perhaps a further attempt at lending legitimacy to the message. In reality, the attachment contained a suspicious. The fake certificate was also touted as a way of connecting the user-machine downloading the certificate with that user’s LogMeIn account. zip file that the senders described as a new security certificate that would protect users against the OpenSSL Heartbleed vulnerability from earlier this year.

What Makes Bitcoin So Volatile

Capitalists are continuously nervous regarding 'Bitcoin" s volatility. It is important to recognize what makes the worth of this certain cybercash exceptionally unstable. Similar to great deals of various other points, the well worth of 'Bitcoin' likewise depends upon the policies of need, also, to supplying if the demand for 'Bitcoin' rises, after that the price will also enhance. On the other hand side, the reduction popular for the 'Bitcoin' will certainly cause the decreased need. In straightforward words, we can mention that the price is established by what quantity the trading market is approved pay. If much more individuals want to market 'Bitcoin's, after that the price will come down.

It is worthy of acknowledging that the value of 'Bitcoin' can be unforeseeable if contrasted to even better-established products in addition to money. This reality can lead to its rather small market measurement, which indicates that a low quantity of financing can relocate the price of 'Bitcoin' far more clearly. This distinction will decrease naturally over the circulation of time as the cash produces along with the market dimension expands.

After being teased in late 2016, 'Bitcoin' touched a brand-new document high level in the initial week of the here and now a year. There could be several parts creating the 'Bitcoin' to be unpredictable. A few of these are spoken about right below.

The Criticism Variable

Bitcoin clients primarily inhibited by different details events consisting of the statements by federal government authorities in addition to geopolitical occasions that 'Bitcoin' can. It implies the price of Bitcoin cultivating is bothered by negative or objection records. Different issue tales developed stress and anxiety in investors together with forbidden them from acquiring this digital financing. An instance of poor heading information is the impending application of 'Bitcoin' in handling medication purchases using Silk Roadway which stressed an end with the FBI disturbance of the market in October 2013. This type of stories developed panic among people along with activated the 'Bitcoin' worth to minimize dramatically. Beyond, experts in the trading market saw such unfavorable incidents as proof that the Bitcoin market is expanding. So the 'Bitcoin' began to acquire its improved well worth not long after the effect of criticism went away.

Alterations of the Concerned Worth

An additional remarkable variable for 'Bitcoin' value ahead to be unforeseeable is the variation of the 'Bitcoin" s perceived worth. You could recognize that this electronic money has residential properties comparable to gold — a design choice guidelines this by the producers of the core technology to restrict its manufacturing to a fixed amount, 21 million BTC. As a result of this component, plutocrats may assign much less or even more property or industrial buildings in the right into 'Bitcoin.'.

Details concerning Security And Security and security Infractions

Various details companies play an essential obligation in developing an unfavorable or favorable public principle. If you see something Advantageously, you are probably to pick that without paying much emphasis to unfavorable sides. There has been information worrying 'Bitcoin' safety and security infractions along with it made the plutocrats hesitate before spending their challenging made money in 'Bitcoin' trading. They furthermore end up being vulnerable to choosing any specific 'Bitcoin' investment platform. 'Bitcoin' might end up being uncertain when 'Bitcoin' area uncovers safety susceptibilities to create an excellent open source reaction in a sort of security and security as well as additionally defense services. Such security issues give birth to several open-source software programs such as Linux. For that reason, it is a great suggestion that 'Bitcoin' programmers require to reveal safety susceptibilities to the public to make solid solutions.

Today 'OpenSSL' weak points struck by 'Heartbleed' insect and also furthermore reported by Neel Mehta (a participant of Google's safety and safety and security and security as well as security team) on April 1, 2014, turn up to had some coming down result on the worth of 'Bitcoin.' According to some documents, the 'Bitcoin' worth decreased around 10% in the taking place month as contrasted to the UNITED STATE Dollar.

Little selection worth for owners of huge 'Bitcoin' Proportions

The volatility of 'Bitcoin' also counts on 'Bitcoin' proprietors having massive portions of this cybercash. It is not clear for 'Bitcoin' enrollers (with existing holdings over $10M) that just how they would handle a configuration that expands right into a fiat arrangement without transferring the market dramatically. So 'Bitcoin' has not touched the mass market cultivating prices that would be important to supply alternate worth to large 'Bitcoin' proprietors.

Effects of Mt Gox

The current prominent troubles at 'Mt Gox' are an additional remarkable aspect for the 'Bitcoin' volatility. All these losses, in addition to the resultant info concerning hefty losses, had a dual influence on instability. You may not acknowledge that this lowered the basic float of 'Bitcoin' by almost 5%. This, also, created a possible lift on the reoccurring 'Bitcoin' worth because of the element of improved lack. Nevertheless, superseding this lift was the negative outcome of the info series that adhered to. Specifically, many other 'Bitcoin' gateways saw the huge stopping working at Mt Gox as an enthusiastic point for the long-lasting feasible consumers of the Bitcoin.

Online Personal Security

Source: https://www.bioedge.org/bioethics/no-privacy-in-a-transhumanist-future-says-former-presidential-candidate/12759

Online security is one of, if not the biggest concern for a lot of internet users. Personal info is left scattered online, payment details, browsing history, chat logs, and much more. While there are things you can do to increase your security online, you never are truly 100% safe. Here are some general tips you can use to further increase your online security as well as how they get bypassed.

·         Secure your personal network – Having an unsecure network at home is the equivalent of having your front door completely unlocked at night! A secure network provides protection to the traffic going through your router. Applying any protection is better than having no security at all. One of the most common encryptions used a few years back was WEP (Wired Equivalent Privacy).

Source: https://www.wirelesshack.org/step-by-step-kali-linux-and-wireless-hacking-basics-wep-hacking-part-3.html

How it’s broken - Since then WEP has been proven to be vulnerable to attack, it isn’t recommended to use. It can be used in 64-bit strength and 128-bit strength. 256-bit has been introduced as well, but you hardly ever see it implemented, if ever. In 64-bit WEP it has a secret key of 40 bits and an initialization vector of 24 bits. In 128-bit WEP this increases to 104-bit secret key and the initialization vector is still the same at 24-bits. There are two methods to breaking WEP. We’re only going to cover one, the FMS attack. The attack is named after Fluhrer, Mantin, and Shamir. It’s based on a flaw of the RC4 encryption algorithm. The three discovered that since throughout the different sizes of WEP and the fact that they all used the same initialization vector this limits the possibility of initialization vectors to 16 million. Of all those combinations, 9000 of them were found to be weak. If one were to collect enough of these IV’s, you can recreate the key needed to connect to the network. You’re probably wondering how people collect these IV’s in the first place. This is where monitor mode comes in. This is a special mode that is available on all wireless cards, you just need software to tell your wireless card to go into this mode. Once it’s in monitor mode, you can use your wireless card to collect wireless packets that are transmitting between your computer and your router. After collecting 5 million packets or so (this takes about 10 minutes tops) you’ll have collected 3000 IV’s, roughly. These packets are then passed through a program that will calculate the first byte of the WEP key. The procedure is then repeated until the full key is discovered.

 Is there another option? – Yes! WPA was passed as the standard later after WEP was proven to be broken. This as well was proven to be vulnerable to other forms of attack. This is when WPA2 was introduced. WPA2 is secure for the most part. It’s vulnerable to dictionary-based attack. This involves having a massive list of possible passwords and hammering the router with these passwords until you get lucky. Later on the in the lifespan of WPA2 there was a discovery in the WPS (Wi-Fi Protected Setup) feature in most routers. To be clear, this isn’t a fault in WPA2, this is a weakness in WPS.

 How it’s broken, again – A WPS Pin is 8 digits long, the last digit is used as a checksum for the previous 7 digits. This means 107 = 10,000,000 million possible combinations. Surely, this is a ridiculous number of pins to test and go through, correct? When a pin is tested, it’s split in 2 parts, the first 4 digits are checked and if it passes, the following 4 digits (3 technically since the last digit is used as a checksum) are checked as well. 104 = 10,000 possible tests for the first half of the WPS pin. This is much more reasonable to brute-force and check. Once the first half is found, the following 3 digits are brute-forced which is again, 103 = 1000. Only a thousand combinations for the 2nd half of the pin. 11,000 total combinations to test and eventually connect to the network. 11,000 down from 10,000,000 million is much more possible. Let’s talk about mitigation. The WPS Pin attack has been around for a few years now and has been patched by most router manufacturers. After 3 attempts the router locks out the WPS feature and needs to be restarted to get more attempts at guessing. While this, doesn’t fix the problem, it makes the process of getting into a network take a much longer amount of time. The latest vulnerability in routers though, is a fault in WPA2 itself. It’s called KRACK. While this is the most interesting of the attacks, I will not be explaining the details as that would result in a paper on this subject alone. KRACK is short for Key Reinstallation AttaCK. To summarize, WPA2 uses a 4-way handshake to encrypt packets. By capturing and resending the 3rd message sent you can capture any network encrypted data and decrypt it. While this doesn’t give you the network passcode to connect to the router, it makes the content of whatever you’re doing very readable. Therefore, it is recommended to use ��The S”. This is the S in HTTPS. The S stands for secure. It means whatever you’re doing on that webpage is encrypted from your pc to the other site you’re on.

 ·         Strong passwords/2 Step Verification – We all have those 2 emails we use for everything. A primary and a secondary. Without these, we’d be lost. Strong passwords are a common thing people struggle with. The most common password in 2017 was “123456” (http://fortune.com/2017/12/19/the-25-most-used-hackable-passwords-2017-star-wars-freedom/). People struggle with making secure passwords as well as using words in their passwords. A good place to check how long it would take a computer to guess your password is https://howsecureismypassword.net/ but this doesn’t stop dictionary attacks. Dictionary attacks are based off long word lists with numbers as well depending on how big the list is. Nowadays there are password managers that can generate and store passwords for you on the fly. This often assures that each password is unique and isn’t easily guessable. This can be a double-edged sword. You’re putting all your trust and personal details in someone else’s hands. LastPass is a password manager that is used by millions. They were hacked once in 2015 (https://lifehacker.com/lastpass-hacked-time-to-change-your-master-password-1711463571) and again in 2017 (https://www.cnet.com/forums/discussions/last-pass-hacked-again/) during both hacks, users were told to change their master passwords that decrypted their databases that stored every password they used. Another common additional step that users like to add as another measure of precaution is 2 Step Authentication. This is the process of using your phone to generate a token that is usually 6 numbers to prove you’re the owner of whatever account you’re trying to access. Another tip with passwords, change them often! Most of the time people never change passwords.

·         Use the S – The S in HTTPS is a new standard that encrypts traffic of websites you browse and secures the payment info when you buy something online. Less than 60% of the internets most popular websites have secure implementation. Generally when you see a lock next to your URL. You’re using https and you’re safe. Back in 2014 there was a bug that affected OpenSSL. OpenSSL is a library that was used by many services to implement https on many sites. This bug was called Heartbleed. Some popular sites that were affected by said bug include, Instagram, Google, Yahoo, AWS(Amazon Web Services) (https://mashable.com/2014/04/09/heartbleed-bug-websites-affected/#K3TT49sSLaqm ). Those are just a few, most of the affected sites have issued patches to address the issue. Generally though, https is the ideal you want to use.

·         Conclusion – Regardless of what tips there are to improve your online security, there are ways around many security measures. Bugs get discovered and patched. Online security is a extremely fast paced environment. Nothing you do online is 100% safe, but there are precautions you can take to improve the protection you have online.

What Causes Bitcoin's Extreme Volatility?

Traders are usually concerned about the volatility of 'Bitcoin.' It's crucial to understand what makes the value of this particular digital currency so volatile. The value of 'Bitcoin,' like many other things, is determined by the laws of supply and demand. If the price of 'Bitcoin' rises in response to increased demand, the price will rise as well. On the other hand, a drop in demand for 'Bitcoin' will result in a drop in demand. Simply said, the price is decided by the amount that the trading market has agreed to pay. The price of 'Bitcoins' will climb if a big number of individuals want to buy them. If more people want to sell their 'Bitcoins,' the price will drop.

When compared to more established commodities and currencies, the value of 'Bitcoin' can be somewhat erratic. This is because to its relatively limited market size, which implies that a smaller quantity of money can have a greater impact on the price of 'Bitcoin.' As the currency evolves and the market size expands, this discrepancy will gradually decrease.

After being teased in late 2016, 'Bitcoin' hit a new all-time high in the first week of this year. The 'Bitcoin' could be volatile due to a number of variables. Some of them are addressed in this article.

The Negative Press

Users of 'Bitcoin' are generally alarmed by various news events, such as statements by government officials and geopolitical events implying that 'Bitcoin' may be regulated. It means that unfavorable or negative press reports are affecting the rate of 'Bitcoin' acceptance. Various negative news stories instilled panic in investors, preventing them from investing in the digital money. The widespread use of 'Bitcoin' in processing drug transactions through Silk Road, which came to an end when the FBI shut down the market in October 2013, is an example of terrible headline news. People became panicked as a result of such stories, and the value of 'Bitcoin' plummeted. Veterans in the trading sector, on the other hand, see such unfavorable instances as proof that the 'Bitcoin' industry is maturing. As a result, the 'Bitcoin' began to appreciate in value shortly after the negative news faded.

The Perceived Value's Fluctuations

The change of the 'Bitcoin"s perceived worth is another major reason for the 'Bitcoin"s value to become erratic. You may be aware that this digital currency has gold-like qualities. This is governed by the core technology's designers' decision to limit manufacturing to a fixed amount of 21 million BTC. As a result of this element, investors may decide to put less or more money into 'Bitcoin.'

Security Breach Information

Various news organizations and internet media play a crucial role in shaping public perceptions, whether unfavorable or positive. If you perceive something presented as advantageous, you are more likely to choose it without considering the disadvantages. There has been news regarding 'Bitcoin' security breaches, which has prompted investors reconsider their decision to spend their hard-earned money in 'Bitcoin' trading. They become overly reliant on any certain 'Bitcoin' investment platform. When the 'Bitcoin' community discovers security vulnerabilities and works to build a great open-source solution in the form of security updates, 'Bitcoin' may become volatile. As a result of these security concerns, open-source software such as Linux was born. As a result, it is recommended that 'Bitcoin' developers reveal security flaws to the wider public in order to develop robust fixes.

The latest 'OpenSSL' flaws exploited by the 'Heartbleed' bug and revealed by Neel Mehta (a Google security team member) on April 1, 2014, appear to have had a negative impact on the value of 'Bitcoin.' According to some sources, the value of 'Bitcoin' fell by up to 10% in the following month when compared to the US dollar.

Holders of significant 'Bitcoin' Proportions have a low option value.

The volatility of 'Bitcoin' is also influenced by the fact that many people own substantial amounts of this digital money. It's unclear how 'Bitcoin' investors (with current holdings of over $10 million) might settle a position that expands into a fiat stake without significantly impacting the market. As a result, 'Bitcoin' has yet to reach the mass market adoption rates that are required to provide option value to large 'Bitcoin' holders.

The HeartBleed Bug

The encryption flaw that punctured the heart of the Internet and has left almost two-thirds of the world's websites vulnerable to attack by hackers.

This bug was discovered on April 07, 2014, by Neel Mehta from Google Security and the team of security engineers (Riku, Antti and Matti) from Codenomicon and has affacted v1.0.1 and 1.0.2-beta releases of OpenSSL including 1.0.1f and 1.0.2-beta1.

XKCD does a better job of explaining a lay man's version of the bug. For a more technical description, I would recommend reading Cloudfare's version of explanation. They even had a challenge page setup to lure hackers to expose the vulnerabilities of the web server by hacking in to the private key of the SSL certificate.

Within 3 hours, Fedor Indutny, a core team member of Node.js cracked the encryption and made the RSA key public. Someone also added a bounty on Hacker News for whoever published and confirmed successful completion of this challenge.

The Bug

The Heartbleed bug, revealed on Monday, was the product of a fluke introduced by a young German researcher. He admitted that he had unintentionally introduced the bug on New Year's Eve 2011 while working on bug fixes for OpenSSL.

The bug was missing a bound check in the handling of the TLS heartbeat extension that can be used to reveal up to 64k of memory to a connected client or server. The precise flaw in the source code is illustrated here on Github, touted as a billion dollar mistake due to poor coding implementation which resulted into this bug.

The Heartbleed bug - Yasoob Khalid

Hi guys! I haven’t been posting a lot recently. There are a couple of problems which have joined up and have kept me away from my computer. I will cover those reasons in the next post. So what this post is about? Are you a sys-admin or a web master? If you are one then the chances are that you have already heard of the heartbleed bug. But for those who are unaware of this, let me explain. On 7th April a bug was spotted in OpenSSL (Yes that is the same encryption used by companies like Google, Facebook, Yahoo! etc on their websites). This bug allowed any hacker to send some carefully crafted packets to a server using OpenSSL and the server responded with more data than it should. It is a very serious vulnerability. The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users. So what does this post has to do with the bug? Well I am going to share two Python scripts with you which will help you test whether a website is vulnerable to this bug or not. Read the full article

#1yrago The internet's core infrastructure is dangerously unsupported and could crumble (but we can save it!)

Nadia Eghbal's Roads and Bridges: The Unseen Labor Behind Our Digital Infrastructure is a long, detailed report on the structural impediments to maintaining key pieces of free/open software that underpin the internet -- it reveals the startling fragility of tools that protect the integrity, safety, privacy and finances of billions of people, which are often maintained by tiny numbers of people (sometimes just one person).

The paper is excellent, but suffers from some organizational deficits, the first being a lack of a good executive summary for people who aren't sure if they want to read 142 pages; the second being that the main event really starts on page 58, in the "Challenges Facing Digital Infrastructure" (the preceding is history and background), which moves on to strategies for fixing things.

I saw an incredibly important presentation on this last week at the O'Reilly Security Conference in New York: Susan Sons's Saving time: How a few committed people helped hold up the Internet. . .again. Sons works with Indiana University's Center for Applied Cybersecurity Research and the Internet Civil Engineering Institute, and her presentation recounted her work to drastically improve and stabilize the Network Time Protocol (NTP).

NTP is how virtually every computer you interact with keeps its clock accurate, which is a function so fundamental to the functioning of the internet that it can't be overstated. Without NTP, huge chunks of metaphorical concrete would crumble and fall off of our virtual bridges, sowing chaos and misery. What's more, vulnerabilities in NTP had turned the internet's many time-servers into force-multipliers for Denial of Service attacks, making merely punishing attakcs into nearly unstoppable ones.

Until ICEI and CACR got involved with NTP, it was supported by one person, part time, who had lost the root passwords to the machine where the source code was maintained (so that machine hadn't received security updates in many years), and that machine ran a proprietary source-control system that almost no one had access to, so it was very hard to contribute to it.

Sons's presentation ended with a showstopper slide showing how much of the internet's key infrastructure was supported by one, two or three people. Recall that in the wake of the Snowden revelations, we learned that the world's most widely used email encryption tool was maintained part-time by one guy, who was going broke. Thunderbird, the mail client that this tool relies on, is now effectively orphaned.

Recall that when Heartbleed struck, revealing that Openssl -- which secures billions of dollars' worth of transactions, not to mention many other kinds of sensitive data-handling -- had been dangerously insecure for many years, we learned that it, too, had one full-time, (under)paid maintainer.

I was so impressed by Sons's work that I ended up donating to both CACRand ICEI. The combination of Eghbal's exhaustive research and Sons's holistic approach to analyzing, organizing and streamlining vulnerable infrastructure is just what we need: a statement of an urgent problem and a plausible way to solve it.

We spend a lot of time talking about "the cyber," and usually, we're talking about sexy attacks on specific websites or services. But these deep, unsexy, structural problems in the internet's core services pose a threat that's much more grave than the 0-days in Ios or Android, or poor Internet of Things security.

こんにちは、CX事業本部の若槻です。 Webアプリケーション向けのセキュリティ診断ツールの定番として、OWASP ZAPというオープンソースツールがよく使われています。 今回は、Docker版のOWASP ZAPを使用してWebアプリのログインページの簡易的な脆弱性診断を行ってみました。 なぜDocker版を使ったのか OWASP ZAPにはWindows、Mac、Linuxで使えるインストーラー版およびパッケージ版と、Docker版があります。 当初はMac向けインストーラー版を使おうとしましたが、Macのセキュリティによりインストールできなかったため断念しました。 よってインストールを要しないDocker版を使うこととしました。 やってみた 今回は次のようなAmplify（CloudFront） + Reactにより実装したのログインページを診断対象としました。 コマンドでDockerイメージowasp/zap2docker-stableをプルします。 % docker pull owasp/zap2docker-stable Using default tag: latest latest: Pulling from owasp/zap2docker-stable 423ae2b273f4: Pull complete de83a2304fa1: Pull complete f9a83bce3af0: Pull complete b6b53be908de: Pull complete dfa4c0ed9f01: Pull complete 0d0271dc7f26: Pull complete ba10134fb40f: Pull complete a5566afd045d: Pull complete 7b60e2849bd0: Pull complete daf051f52216: Pull complete 3600cd933995: Pull complete a1d63c5e9c9f: Pull complete 86279da9d5e1: Pull complete 61d20517a689: Pull complete b645cc4494b6: Pull complete 87a41273fa00: Pull complete dcd8983ba399: Pull complete 424fa8727c16: Pull complete Digest: sha256:3563ecc53448ad224262ccea185cff8360c999c52d9c4b78630d9344dc1c3fd6 Status: Downloaded newer image for owasp/zap2docker-stable:latest docker.io/owasp/zap2docker-stable:latest Docker版ZAPのスキャンタイプにはいくつかの種類がありますが、今回は攻撃および負荷のあるアクセスを伴わない1分間の静的スキャンを実施するBaseline Scanを行いました。次のコマンドで実行が可能です。 ログインページhttps://example.com/loginに対してBaseline Scanを実行してみます。 % docker run -t owasp/zap2docker-stable zap-baseline.py -t https://example.com/login 2020-09-10 09:03:38,813 Params: ['zap-x.sh', '-daemon', '-port', '38996', '-host', '0.0.0.0', '-config', 'api.disablekey=true', '-config', 'api.addrs.addr.name=.*', '-config', 'api.addrs.addr.regex=true', '-config', 'spider.maxDuration=1', '-addonupdate', '-addoninstall', 'pscanrulesBeta'] _XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be created.

Bitpay QR codes are no longer valid. Important Notice.

Very recently and without much notice or discussion with developers, one of the largest Bitcoin payment processor for merchants, Bitpay, decided to drop support entirely for the bitcoin standard scheme for displaying a payment request to an end-user known as BIP21. In replacement of BIP21 - which is universally supported and implemented by all Bitcoin wallet and service providers since 2012 - Bitpay will present a payment request to users that conforms to a controversial proposal that is not widely supported (BIP 70).

What is BIP21?

BIP21 is an open standard deployed and enabled by all bitcoin wallets and services since 2012. Following the rules laid out in BIP21 ensures that no matter the wallet software or service used, the QR code and payment request must be created and interpreted in one standard way. This ensures maximum compatibility and interoperability between software and services all operating in a decentralized open source network. Needless to say, Bitpays decision to drop all support for this fundamental open standard, will harm the overall user experience not improve it, as they claim to be striving for.

What is Bitpay’s Payment Protocol?

Bitpay has replaced BIP21 entirely with different, more controversial proposals, BIP’s 70,71,72. BIP70 was originally proposed by Gavin Andresen and Mike Hearn in 2013 - who championed creating bitcoin blacklists - generated a lot of controversy and remains largely unadopted by the majority of wallet and service providers due to many security and privacy concerns.

BIP70 introduces the requirement on developers to support legacy public-key infrastructure dependencies with known track records of vulnerabilities (openssl and heartbleed, etc...). Additionally, widespread implementation of BIP70 introduces an exposure to increased risk of AML/KYC surveillance and monitoring of on-chain transactions and more effective blacklists.

Moving forward

We have to be very clear here. Samourai Wallet will not support BIP70 in our products, therefore, our wallet users will NOT be able to send bitcoin to QR codes generated by Bitpay invoices, as they do not provide a valid Bitcoin address. If you want to make payments to a QR code provided by Bitpay you will need to use a wallet that has enabled BIP70.

We absolutely do not support Bitpay in agressively using their dominant position of market share to bully wallet providers into supporting their business plans or bully users into a system that degrades their privacy and the fungibility of bitcoin as a whole. Bitpay should focus on repairing their image and brand after the cataclysmic failure of the Segwit2x Fork they helped architect, instead of reinforcing their image as an out of touch bully looking to hijack the network for their own gain.

Users should stand up to this kind of arrogance and stand up for their privacy. Samourai has already started the process of contacting all vendors we rely on who utilize BitPay as a payment processor and informing them of our intention to switch vendors, as using Bitpay is no longer tolerable or feasible. We hope others join us.

We are available as always to answer any questions on support.samourai.io or by email at support@samouraiwallet.com
