What are The Types of Ransomware and Ransomware History

Cyberattacks like ransomware are serious. Among the most dangerous malware, they can affect any company. Within four days of network access, attackers deploy ransomware, leaving little time for detection and prevention. Stopping operations, losing money, reputation, and data.

According to the IBM Cost of a Data Breach report, ransomware breaches average USD 5.68 million, excluding ransom payments. Not all ransoms reach $80 million.

Better threat detection and prevention reduced ransomware attacks 11.5% between 2022 and 2023.

The Ransomware Types

Varying ransomware strains exploit vulnerabilities.

Crypto ransomware: Locks important files until a ransom is paid. WannaCry, Locky, CryptoLocker. Ransomware encrypts.

Without payment, this ransomware blocks the victim's device or system from accessing files or apps. Screen-locking ransomware isn't encrypted.

Scareware: Fake software that diagnoses system issues and recommends dangerous fixes. Scareware can restrict system access or bombard users with pop-ups to install malware or pay. Scareware can provide or be ransomware.

Leakware, or doxware, steals confidential data and threatens disclosure without payment. The attacks pressure victims with reputational danger. Modern variants steal and encrypt data.

Mobile ransomware: Spreads via malicious apps or drive-by downloads. Most mobile ransomware involves screen-lockers since cloud backups make encryption attacks easier to reverse.

If unpaid, ransomware wipes data. Ransomware by cybercriminals and nation-states erases data after payment.

Modern ransomware uses double- and triple-extortion. Unpaid double-extortion threatens to steal and publish vulnerable data online. Consumers or business partners with stolen data face triple extortion. Even with data backups, these methods raise the stakes. Since 2019, the IBM Security X-Force incident Response team has seen double extortion in most ransomware events.

Infection via Ransomware

Ransomware can attack systems via multiple channels. Well-known methods:

Phishing uses emails with phoney attachments or malicious websites to get people to download and run hazardous programs.

Zero-day vulnerabilities in operating systems and applications allow cybercriminals to inject malware. The 2017 WannaCry assault used fixed vulnerabilities.

Stolen, bought, or cracked user credentials are used to log in and deploy ransomware via Remote Desktop Protocol (RDP).

Malware like Trickbot Trojan (which seeks banking details) can spread ransomware.

Drive-by downloads: Ransomware can infiltrate devices without user awareness via exploit kits or malvertising.

In legitimate online interactions, cybercriminals utilise thread hijacking to spread malware.

RaaS: Ransomware as Service

Cybercriminals distribute ransomware via RaaS. Malware developers share code with “affiliates” who split the ransom. Developers and affiliates can benefit without releasing new attacks or malware. RaaS distributors can sell dark web access or recruit affiliates. Major ransomware gangs have recruited affiliates.

Staged Ransomware Attack

Typical ransomware attacks include many phases:

Initial access: Phishing, vulnerability exploitation, or hacked RDP protocols give attackers access.

After initial access, attackers may utilise RATs to consolidate.

After acquiring access to a system or network, attackers may lateral migrate to other systems and domains.

Ransomware thieves steal credentials, customer data, and IP. Double-extortion uses data theft.

File encryption, system restoration disablement, and backup deletion/encryption increase pressure with crypto ransomware. Unencrypting ransomware locks or spams the device. The ransomware then delivers a text file or pop-up window with instructions on how to pay the ransom (usually in cryptocurrency) to decrypt or regain access.

History of ransomware

Thousands of ransomware variants exist. Some prominent ones:

The AIDS Trojan was the first floppy-disk ransomware in 1989. It concealed file directories but was easily reversed.

CryptoLocker, introduced in 2013, allowed cryptocurrency ransomware.

An unpatched Microsoft Windows vulnerability attacked 200,000 devices in 150 countries with WannaCry. The ransom threatens file deletion if not paid.

File system table encryption by Petya and NotPetya affects PC booting. A 2017 Ukraine attack utilised a modified NotPetya wiper that could not restore systems after payment.

Ryuk, a 2018 ransomware attack, popularised large-scale attacks on high-value targets with high demands. It finds and disables backups.

A purported Russian gang, DarkSide, assaulted the Colonial Pipeline in 2021, briefly halting petroleum supplies. The group licenses ransomware using RaaS.

Encrypting malware Locky hides hazardous macros in email attachments, usually bills.

IN 2021, REvil (Sodinokibi) popularised RaaS for big-game hunting and double-extortion attacks against JBS USA and Kaseya Limited.

Since 2020, the Conti gang's large RaaS scam paid hackers. In a unique double-extortion scheme, Conti threatened to sell network access to hackers. After 2022 internal communication dumps, the gang separated, however former members are tied to BlackBasta, Royal, and Zeon.

A popular 2023 ransomware version is LockBit. The company is known for businesslike conduct and malware acquisition. LockBit assaults victims despite police efforts.

Paying Ransom

An average ransom is hard to quantify, however estimates range from six to seven figures. Ransom payments dropped from 70% in 2020 to 37% in 2023, perhaps owing to better planning.

Agents from the FBI and NCIJTF aggressively discourage ransom payments. Payment may not retrieve data, strengthen attackers, support criminal conduct, or promote more attacks.

Strong backup systems provide negotiation-free recovery. Authorities recommend reporting attacks before paying. Payment of ransom to attackers from US economic sanctions or state governments in particular US regions is illegal.

Ransomware prevention

Ransomware prevention requires technology and user behaviour. Main strategies:

Regular OS, app, and firmware upgrades fix ransomware security holes.

Detect and eliminate threats using real-time scanning, behavioural detection, and automated updates from contemporary antivirus and anti-malware software.

A good firewall blocks unauthorised network access.

Phishing prevention: Email filtering and scanning detects suspicious links and attachments.

Regular backups speed recovery without ransom. Secure, immutable backups can restore data if systems fail. Data should be replicated three times on two media types, one offsite. Seagate Lyve Cloud backups offer geographic redundancy, encryption, and immutability.

Firewalls, intrusion detection systems, network segmentation, and secure VPNs help thwart attacks. Least privilege access and endpoint security harden networks.

AI can predict and stop assaults by studying behaviour, detecting anomalies, and stopping attacks before they start. AI-powered systems can monitor users and endpoints, detect zero-day attacks, and respond faster using playbooks.

Policies and procedures: Ready crisis response requires a detailed strategy with responsibilities, timetables, and communication channels.

Teams require regular security awareness training to spot phishing and suspicious emails because human error is a huge risk.

Ransomware Response Plan

Every system is vulnerable, hence a detailed response strategy is needed. Actions include:

Disconnect compromised systems immediately to stop ransomware.

Report to authorities: Request FBI or CISA law enforcement assistance. Legal duties may require reporting.

Damage assessment: Identify affected systems, assess data compromise, and contain with IT/security teams.

Use the latest clean backup to restore data. Immutable solutions like Seagate Lyve Cloud are needed for reliable recovery. Inform employees, partners, and consumers to build trust and reputation.

Don't pay the ransom: Experts say it may not retrieve data and may encourage more attacks.

One of the most fun traits is that sufficiently out of date viruses are ineffective on modern machines, and on older machines any kind of modern virus or malware usually fails! Especially in this age of IS-integral AV that knows about anything that's existed a few weeks, let alone a few years or decades.

For example, if you run a windows 98 machine on the modern-day web, most currently spreading viruses and malware just won't run. They're built to expect an NT kernel, which windows 9x doesn't have. They try to cryptolocker your files and the whole process fails to run because the 9x machine has none of the cryptographic support those malware people expect. It's exceedingly difficult for an infected and active 98 machine to reach out across the modern internet and successfully infect your computer with windows 98 cuz that software is designed around styles of access and kinds of routing rarely used now - the suspicious content is likely to be blocked by simple filters in home routers and big isp scanning equipment.

You can still hunt down and pick up known infected 98 compatible software if you want to force your 98 computer to have a bad time - but it'll be nearly impossible for it to spread its infection elsewhere!

"I downloaded these torrents in high school and then I forgot about them and never inspected or opened them, so it might be a video game, or it might be like a sealed canopic jar full of ancient viruses."

INFORMATION - YOU ARE HACKED !

!!!!!!!!!! IMPORTANT MESSAGE !!!!!!!!!!!!!! IMPORTANT MESSAGE !!!!!!!!!!!!!! IMPORTANT MESSAGE !!!!!!!!!!!!!!

HELLO, YOUR CORPORATE NETWORK HAS BEEN HIROLLED. There are special pigeonholes all over the network waiting for our command to lock down your network. Don't try to detect them, our software is set up so that if you remove one brick, the rest will immediately attack your corporate network crypto.

The speed at which our software has time to block your entire network is - 15 minutes.

!!! WE ARE NOT AFFILIATED WITH THE GOVERNMENT OF ANY COUNTRY. OUR GOAL IS COMMERCIAL GAIN !!!

This is an important message. Your company was attacked by cryptolockers and was successfully hacked.

As a result of the attack 213GB of information was downloaded, including accounting documents and information that constitutes trade secrets. We are working under a new scheme so as not to represent inconvenience to the company with which we are dealing with that is why before we block your computers we offer solve the issue for a small compensation (which is much less than what will be after exploiting your vulnerability and your computers) in the amount of $1153. You have 24 hours to respond to the message.

Pay within 24 hours.

Bitcoin address is: bc1qcj67jfx6e9wcg3s5sylp7pld8vaq0faa3jspwm

You can easily buy bitcoin here:

www.paxful.com

www.coingate.com

www.localbitcoins.com

www.coinbase.com

or check for bitcoin ATM near you, or Google for other exchanger.

You can send the bitcoin directly to BTC address, or create your own wallet first here: www.login.blockchain.com/en/#/signup/

then receive and send to mine.

Do not try to go to the police, you will only get worse. We suggest that you resolve the matter amicably without inconveniencing you. If you do not comply with our demands, we will continue the attack and block your system and the amount of the ransom will be x1000 times more, to $1,000,000. And also the information that is of commercial value will be published on a special public site.

Agree ransom $1153 is better than $1,000,000, we have automated our work and we are working on speed and produce a massive attack.

Don't try to play with us. You have 24 hours to respond to our message.

All work is done automatically. We have no centralized servers.

There is no point in negotiating with us. The software automatically checks the funds into the wallet and makes a decision based on a neural network. We do not negotiate because it is not safe.

We work on a double attack scheme. If we don't get a small ($1153 ransom) then we go to step 2 - blocking the entire corporate network.

We know exactly when you open this email. And from that point on, the timer starts. You have 24 hours to respond to this message.

Upon receipt of the money, our moyaks will be liquidated and we will leave you alone. All your information will be immediately deleted from our servers.

Also we will send you a security advisory letter about how to set up your corporate network to make sure that this never happens to you again.

The security advisory alone will cost you over $1153.

We do not read the responses to this e-mail. That is why there is no point in writing a letter back.

!!! NO-REPLY NO-REPLY NO-REPLY NO-REPLY NO-REPLY NO-REPLY NO-REPLY NO-REPLY NO-REPLY!!!!

Week 5 - Ransomwares

Blog

What is ransomware?

Ransomware is a type of malware from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as Ukash and cryptocurrency are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

Ransomware attacks are typically carried out using a Trojan that is disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the "WannaCry worm", travelled automatically between computers without user interaction.

Starting from around 2012 the use of ransomware scams has grown internationally. There were 181.5 million ransomware attacks in the first six months of 2018. This marks a 229% increase over this same time frame in 2017. In June 2014, vendor McAfee released data showing that it had collected more than double the number of samples of ransomware that quarter than it had in the same quarter of the previous year. CryptoLocker was particularly successful, procuring an estimated US $3 million before it was taken down by authorities, and CryptoWall was estimated by the US Federal Bureau of Investigation (FBI) to have accrued over US $18m by June 2015.

Types of ransomware

Ransomware can come in many shapes and sizes. Some variants may be more harmful than others, but they all have one thing in common: a ransom. The five types of ransomware are:

Crypto malware. This is a well-known form of ransomware and can cause a great deal of damage. One of the most familiar examples is the 2017 WannaCry ransomware attack, which targeted thousands of computers around the world and spread itself within corporate networks globally.

Lockers. This kind of ransomware is known for infecting your operating system to completely lock you out of your computer, making it impossible to access any of your files or applications.

Scareware. This is fake software that acts like an antivirus or a cleaning tool. Scareware often claims to have found issues on your computer, demanding money to resolve the issue. Some types of scareware lock your computer, while others flood your screen with annoying alerts and pop-up messages.

Doxware. Commonly referred to as leakware, doxware threatens to publish your stolen information online if you don’t pay the ransom. As more people store sensitive files and personal photos on their computers, it’s understandable that many individuals panic and pay the ransom when their files have been hijacked.

RaaS. Otherwise known as “Ransomware as a Service,” RaaS is a type of malware hosted anonymously by a hacker. These criminals handle everything from distributing the ransomware and collecting payments to managing decryptors — software that restores data access — in exchange for their cut of the ransom.

Ransomware remains a popular means of attack, and new ransomware families are discovered every year. Reported attacks in the U.S. dropped from 2,673 in 2016 to 1,783 in 2017. However, the threat of ransomware is still incredibly active on the internet.

CryptoLocker

CryptoLocker was a ransomware trojan which used the Gameover ZeuS botnet and infected email attachments to spread across the Internet, infect Windows PCs, and lock files using RSA 2048-bit encryption. Victims are then prompted to pay a $300 ransom in order to receive a password. Since it wasn’t a virus, it didn’t spread across your network on its own. However, it was still capable of doing a lot of damage.

CryptoLocker affected around 500,000 people between September 2013 and May 2014. In a crackdown dubbed “Operation Tovar”, a group of security experts — from the FBI, Interpol, security software vendors, and universities — managed to stop the hackers.

Although CryptoLocker itself was easily removed, the affected files remained encrypted in a way which researchers considered unfeasible to break. Many said that the ransom should not be paid but did not offer any way to recover files; others said that paying the ransom was the only way to recover files that had not been backed up. Some victims claimed that paying the ransom did not always lead to the files being decrypted.

WannaCry

The only malware that I have heard of before I started this project as it happened pretty recently in 2017.

In May 2017, the WannaCry ransomware cryptoworm targeted computers running the Microsoft Windows operating system by encrypting data and demanded ransom payments in the Bitcoin cryptocurrency, propagating through Eternal Blue. The initial infection was likely through an exposed vulnerable SMB port, rather than email phishing as initially assumed. The attack was estimated to have affected more than 200,000 computers across 150 countries, with total damages ranging from hundreds of millions to billions of dollars. Security experts believed from preliminary evaluation of the worm that the attack originated from North Korea or agencies working for the country.  It was the first time that ransomware had spread across the world in what looked like a coordinated cyberattack.

When executed, the WannaCry malware first checks the "kill switch" domain name; if it is not found, then the ransomware encrypts the computer's data, then attempts to exploit the SMB vulnerability to spread out to random computers on the Internet, and "laterally" to computers on the same network. As with other modern ransomware, the payload displays a message informing the user that files have been encrypted and demands a payment of around US$300 in bitcoin within three days, or US$600 within seven days. Three hardcoded bitcoin addresses, or "wallets", are used to receive the payments of victims. As with all such wallets, their transactions and balances are publicly accessible even though the cryptocurrency wallet owners remain unknown.

A new variant of WannaCry ransomware forced Taiwan Semiconductor Manufacturing Company (TSMC) to temporarily shut down several of its chip-fabrication factories in August 2018. The virus spread to 10,000 machines in TSMC's most advanced facilities.

Reflection

What techniques do ransomwares usually employ to attack?

There are a number of vectors ransomware can take to access a computer. One of the most common delivery systems is phishing spam — attachments that come to the victim in an email, masquerading as a file they should trust. Once they're downloaded and opened, they can take over the victim's computer, especially if they have built-in social engineering tools that trick users into allowing administrative access. Some other, more aggressive forms of ransomware, like NotPetya, exploit security holes to infect computers without needing to trick users.

How can we combat these?

·       Keeping operating system patched and up to date to ensure fewer vulnerabilities and bugs to exploit

·       Don’t install software or give it administrative privileges unless it’s trusted

·       Installing antivirus software which can detect malicious programs such as ransomware, this prevents unauthorized applications from executing in the first place

·       Back up files frequently. Although this won’t stop a ransomware attack, it can mitigate the damage caused by one

What did CryptoLocker exploit?

CryptoLocker typically propagated as an attachment to a seemingly innocuous e-mail message, which appears to have been sent by a legitimate company. A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension. CryptoLocker was also propagated using the Gameover ZeuS trojan and botnet.

What did Wannacry exploit?

·       WannaCry also took advantage of installing backdoors onto infected systems.

·       EternalBlue is an exploit of Windows' Server Message Block (SMB) protocol released by The Shadow Brokers. Much of the attention and comment around the event was occasioned by the fact that the U.S. National Security Agency (NSA) (from whom the exploit was likely stolen) had already discovered the vulnerability, but used it to create an exploit for its own offensive work, rather than report it to Microsoft. Microsoft eventually discovered the vulnerability, and on Tuesday, 14 March 2017, they issued security bulletin MS17-010, which detailed the flaw and announced that patches had been released for all Windows versions that were currently supported at that time, these being Windows Vista, Windows 7, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2016.

·       EternalBlue was stolen and leaked by a group called The Shadow Brokers a few months prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these or were using older Windows systems that were past their end-of-life.

·       DoublePulsar is a backdoor tool, also released by The Shadow Brokers on 14 April 2017. Starting from 21 April 2017, security researchers reported that there were tens of thousands of computers with the DoublePulsar backdoor installed. By 25 April, reports estimated that the number of infected computers could be up to several hundred thousand, with numbers increasing every day. The WannaCry code can take advantage of any existing DoublePulsar infection, or installs it itself.

 What do we have nowadays that is making this attack hard/still possible?

Anti-malware software is not absolute. Ransomware is constantly being written and tweaked by its developers, and so its signatures are often not caught by typical anti-virus programs. In fact, as many as 75 percent of companies that fall victim to ransomware were running up-to-date endpoint protection on the infected machines.

Ransomware isn't as prevalent as it used to be. The number of ransomware attacks, after exploding in the mid '10s, has gone into a decline, though the initial numbers were high enough that it's still. But in the first quarter of 2017, ransomware attacks made up 60 percent of malware payloads; now it's down to 5 percent.  

In many ways it's an economic decision based on the cybercriminal's currency of choice: bitcoin. Extracting a ransom from a victim has always been hit or miss; they might not decide to pay, or even if they want to, they might not be familiar enough with bitcoin to figure out how to actually do so.

The decline in ransomware has been matched by a rise in so-called cryptomining malware, which infects the victim computer and uses its computing power to create (or mine, in cryptocurrency parlance) bitcoin without the owner knowing. This is a neat route to using someone else's resources to get bitcoin that bypasses most of the difficulties in scoring a ransom, and it has only gotten more attractive as a cyberattack as the price of bitcoin spiked in late 2017.

That doesn't mean the threat is over, however. There are two different kinds of ransomware attackers: "commodity" attacks that try to infect computers indiscriminately by sheer volume and include so-called "ransomware as a service" platforms that criminals can rent; and targeted groups that focus on particularly vulnerable market segments and organizations.

With the price of bitcoin dropping over the course of 2018, the cost-benefit analysis for attackers might shift back. Ultimately, using ransomware or cryptomining malware is a business decision for attackers, says Steve Grobman, chief technology officer at McAfee. “As cryptocurrency prices drop, it’s natural to see a shift back [to ransomware]."  

CryptoLocker

During its spread, any unprotected Windows PC was vulnerable to the trojan. However, CryptoLocker is no longer a threat.

On 2 June 2014, the United States Department of Justice officially announced that over the previous weekend, Operation Tovar—a consortium constituting a group of law enforcement agencies (including the FBI and Interpol), security software vendors, and several universities, had disrupted the Gameover ZeuS botnet which had been used to distribute CryptoLocker and other malware. The Department of Justice also publicly issued an indictment against the Russian hacker Evgeniy Bogachev for his alleged involvement in the botnet.

As part of the operation, the Dutch security firm Fox-IT was able to procure the database of private keys used by CryptoLocker; in August 2014, Fox-IT and fellow firm FireEye introduced an online service which allows infected users to retrieve their private key by uploading a sample file, and then receive a decryption tool
