The software that you install is called Symantec Encryption Desktop, but the UIC license for Symantec Encryption Desktop includes only the Symantec Drive Encryption features. The Technology Solutions is running a Symantec Encryption Management Server, in which your PGP key is protected with your UIC Active Directory ID and password, which is your UIC NetID and your Technology Solutions common password. (You can tell see whether Hibernate is a Shutdown option in the Start menu Search in Help and Support on Windows for "hibernate" for more information.) However, not all Windows computers support or are set up so that they can Hibernate. (Note that if you use Hibernate on Windows machines rather than Sleep, Symantec Encryption Desktop will protect your computer when it wakes. This does not provide the protection that Symantec Encryption Desktop does, but it will keep casual intruders from accessing your computer while it is asleep.

Make sure you turn password protection on for when your computer goes to sleep.

Turn your computer off when you are transporting it, so that it will be protected from booting without logging into Symantec Encryption Desktop.

So there are three additional things you need to do to protect your computer: This "transparency" means that your computer works exactly as it always did after you boot, but it also means that the files you use are not protected when your computer is on, after you authenticate with Symantec Encryption Desktop. Operating system login bypass tricks won't work.Īfter you authenticate and your computer boots, encryption is always on, automatically protecting your data. After your hard disk is encrypted, you must login to Symantec Encryption Desktop before you can boot the computer. After you install Symantec Encryption Desktop on your computer, the disk encryption process will automatically run on its hard drive. The UIC license for Symantec Encryption Desktop centers on Symantec Drive Encryption (formerly known as PGP Whole Disk Encryption / WDE) which securely encrypts the entire contents of your laptop or desktop, including boot sectors, system, and swap files. Symantec Encryption Desktop also includes a secure shredder, to really delete files you want to delete. Laptops and flash drives are easily lost, and even desktop computers can be stolen. Symantec Encryption Desktop provides easy to use and secure encryption to protect sensitive data on your laptop, PC, or removable media. That is not what the UIC license for Symantec Encryption Desktop/PGP Desktop is for.

Download Cryptolocker Virus For Testing

Nov 12, 2013 The Crypto Locker virus is passed around in emails that have innocent enough looking senders, such as UPS or FedEx, but they’re not really from these corporations, of course. Instead, when you open the attachment, your computer becomes infected and the virus locks all your files until you pay a ransom. Jun 30, 2014 thanks. I see so many new samples (like cryotowall 3.0) that I have moved on from the original cryptolocker. As my antivirus protects against all crypto’s using email/web reputation and also detecting the crypto process, then I am no longer looking for policies to prevent. I am using trend micro worry free 9 with sp1 and the latest hotfix for.

What is CryptoLocker?

CryptoLocker is by now a well known piece of malware that can be especially damaging for any data-driven organization. Once the code has been executed, it encrypts files on desktops and network shares and “holds them for ransom”, prompting any user that tries to open the file to pay a fee to decrypt them. For this reason, CryptoLocker and its variants have come to be known as “ransomware.”

Malware like CryptoLocker can enter a protected network through many vectors, including email, file sharing sites, and downloads. New variants have successfully eluded anti-virus and firewall technologies, and it’s reasonable to expect that more will continue to emerge that are able to bypass preventative measures. In addition to limiting the scope of what an infected host can corrupt through buttressing access controls, detective and corrective controls are recommended as a next line of defense.

“This really opened my eyes to AD security in a way defensive work never did.”

FYI, this article is CryptoLocker specific. If you’re interested in reading about ransomware in general, we’ve written A Complete Guide To Ransomware that is very in-depth.

Update September 2018: Ransomware attacks have decreased significantly since their peak in 2017. CryptoLocker and it’s variants are no longer in wide distribution, and new ransomware has taken over. Ransomware has evolved as more of a targeted attack instead of the previous wide distribution model, and is still a threat to businesses and government entities.

What Does CryptoLocker Do?

On execution, CryptoLocker begins to scan mapped network drives that the host is connected to for folders and documents (see affected file-types), and renames and encrypts those that it has permission to modify, as determined by the credentials of the user who executes the code.

CryptoLocker uses an RSA 2048-bit key to encrypt the files, and renames the files by appending an extension, such as, .encrypted or .cryptolocker or .(7 random characters), depending on the variant. Finally, the malware creates a file in each affected directory linking to a web page with decryption instructions that require the user to make a payment (e.g. via bitcoin). Instruction file names are typically DECRYPT_INSTRUCTION.txt or DECRYPT_INSTRUCTIONS.html.

As new variants are uncovered, information will be added to the Varonis Connect discussion on Ransomware. For example, a variant known as “CTB-Locker” creates a single file in the directory where it first begins to encrypt files, named, !Decrypt-All-Files-(RANDOM 7 chars).TXT or !Decrypt-All-Files-(RANDOM 7 chars).BMP.

How to Prevent CryptoLocker

The more files a user account has access to, the more damage malware can inflict. Restricting access is therefore a prudent course of action, as it will limit the scope of what can be encrypted. In addition to offering a line of defense for malware, it will mitigate potential exposure to other attacks from both internal and external actors.

While getting to a least privilege model is not a quick fix, it’s possible to reduce exposure quickly by removing unnecessary global access groups from access control lists. Groups like “Everyone,” “Authenticated Users,” and “Domain Users,” when used on data containers (like folders and SharePoint sites) can expose entire hierarchies to all users in a company. In addition to being easy targets for theft or misuse, these exposed data sets are very likely to be damaged in a malware attack. On file servers, these folders are known as “open shares,” if both file system and sharing permissions are accessible via a global access group.

Although it’s easiest to use technologies designed to find and eliminate global access groups, it is possible to spot open shares by creating a user with no group memberships, and using that account’s credentials to “scan” the file sharing environment. For example, even basic net commands from a windows cmd shell can be used to enumerate and test shares for accessibility:

net view (enumerates nearby hosts)

net view host (enumerates shares)

net use X: hostshare (maps a drive to the share)

dir /s (enumerates all the files readable by the user under the share)

These commands can be easily combined in a batch script to identify widely accessible folders and files. Remediating these without automation, unfortunately, can be a time-consuming and risky endeavor, as it’s easy to affect normal business activity if you’re not careful. If you uncover a large amount of accessible folders, consider an automated solution. Automated solutions can also help you go farther than eliminating global access, making it possible to achieve a true least-privilege model and eliminate manual, ineffective access-control management at the same time.

How to Detect CryptoLocker

If file access activity is being monitored on affected files servers, these behaviors generate very large numbers of open, modify, and create events at a very rapid pace, and are fairly easy to spot with automation, providing a valuable detective control. For example, if a single user account modifies 100 files within a minute, it’s a good bet something automated is going on. Configure your monitoring solution to trigger an alert when this behavior is observed. Varonis DatAlert monitors and tracks file system behavior for ransomware attacks out-of-the-box. There is no need for extra configuration if Varonis is monitoring your data.

If you don’t have an automated solution to monitor file access activity, you may be forced to enable native auditing. Native auditing, unfortunately, taxes monitored systems and the output is difficult to decipher. Instead of attempting to enable and collect native audit logs on each system, prioritize particularly sensitive areas and consider setting up a file share honeypot.

A file share honeypot is an accessible file share that contains files that look normal or valuable, but in reality are fake. As no legitimate user activity should be associated with a honeypot file share, any activity observed should be scrutinized carefully. If you’re stuck with manual methods, you’ll need to enable native auditing to record access activity, and create a script to alert you when events are written to the security event log (e.g. using dumpel.exe).

If you’re PowerShell inclined, we’ve written a bit on how to combat CryptoLocker with PowerShell.

If your detective control mechanism can trigger an automated response, such as disabling the user account, the attack is effectively stopped before inflicting further damage. For example, a response to a user that generates more than 100 modify events within a minute might include:

Notifying IT and security administrators (include the affected username and machine)

Checking the machine’s registry for known keys/values that CryptoLocker creates:

Get-Item HKCU:SoftwareCryptoLockerFiles).GetValueNames()

if value exists, disable user automatically.

If recorded access activity is preserved and adequately searchable, it becomes invaluable in recovery efforts, as it provides a complete record of all affected files, user accounts, and (potentially) hosts. Varonis customers can use the output from report 1a (as described here) to restore files from a backup or shadow copy.

Depending on the variant of CryptoLocker, encryption may be reversible with a real-time disassembler.

Ransomware Safety Tips

Update your antivirus and endpoint protection software – these solutions can help detect certain types of ransomware and prevent it from encrypting your files.

Avoid phishing scams – phishing emails are the most prevalent delivery mechanism for ransomware.

Keep backups of your documents – it’s much faster and easier to recover your documents from a backup than it is to decrypt them, if they’ve been compromised in a ransomware attack.

Commit to a zero-trust/least privilege model – ransomware can only affect the folders a user can write to. A least privilege model limits that access to only what’s absolutely necessary.

Monitor file activity and user behavior to detect, alert and respond to potential ransomware activity.

New ransomware variants are popping up all the time – luckily our dedicated security forensics team does the legwork for you and diligently updates the ransomware signatures that Varonis detects. See how it works with a free 1:1 demo and learn more about how our ransomware defense architecture is designed to protect enterprise data from zero-day attacks beyond the endpoint – catching ransomware that traditional perimeter security doesn’t see.

If you ever needed a reminder to be careful about the emails and attachments you open, it’s now. The Crypto Locker virus that is going around is said to be one of the worst ever and is infecting computers with the Windows OS all across the United States. The virus, also called “ransomware,” works by holding your files hostage until you pay a fee.

The Crypto Locker virus is passed around in emails that have innocent enough looking senders, such as UPS or FedEx, but they’re not really from these corporations, of course. Instead, when you open the attachment, your computer becomes infected and the virus locks all your files until you pay a ransom.

Digital Signatures May Be Prone To Scams – How To Protect Yourself?

Signing documents electronically save time and makes it easier for people to close contracts, sign other legal documents, and fill out tax forms without making trips to the bank, post office, or other courier services. But Digital signatures can also come with risks.

Scammers have come up with a good practice to break the Digital signing system and create fake digital signatures on desktop PDF viewer apps. These include apps such as Adobe Acrobat Reader, Libre Office, and online services like DocuSign.

Digitally signed documents are admissible in court, can be used as a legally binding contract, can be used for Income tax filing purposes, can be used to approve financial transactions, and can be used for press releases and announcements made by the government.

The ability to a fake digital signature on an official PDF document can threaten to steal large amounts of money or cause chaos inside private companies and public institutions.

Three vulnerabilities have been found in the digital signing process used by several desktop and web-based PDF signing services. Summarized, they are:

Universal Signature Forgery (USF) – vulnerability lets attackers game trick the signature verification process so that it will display the user a fake panel/message that the signature is valid.

Incremental Saving Attack (ISA) – vulnerability lets attackers add extra content to an already signed PDF document via the “incremental saving (incremental update)” mechanism, but without breaking the saved info of the signature of that document.

Signature Wrapping (SWA) – vulnerability is similar to ISA, but the malicious code also contains extra logic in order to fool the process of signature. This means the content which was added (the incremental update) has been digitally signed.

The researchers found that there were two root causes of why this sort of spoofing could be carried out.

First, they said, “The specification provides incomplete information and without any concrete procedures on how to validate signatures. Description of pitfalls and any security considerations are missing. Thus, developers must implement the validation on their own without best-common-practice information.”

Secondly, they found “The error tolerance of the PDF viewer is abused to create non-valid documents bypassing the validation, yet correctly displayed to the user.”

How to Protect Yourself?

Avoid sharing sensitive information or financial information over email.

Use two-factor authentication or multi-factor authentication to enhance security.

Have up to date secured apps installed on your device.

Use encrypted email.

Have a more secured transaction process.

With technology enhancement, the chances of online fraud are increasing every day. Taking the advantage of advanced Digital Signing Solution technologies, you can rest easy knowing your documents are safe.
