ShurL0ckr ransomware. How to remove? (Uninstall guide)

removal by Julie Splinters - - | Type: Ransomware

ShurL0ckr – a ransomware virus that avoids detection by most of AV engines

Illustration of the ShurL0ckr ransomware

ShurL0ckr is zero-day ransomware[1] which has been detected by security broker Bitglass and Cylance at the beginning of February 2018. It was confirmed to be a new version of Gojdue ransomware and a Ransomware-as-a-Service[2] type virus. In other words, all people who want to earn money illegally by locking people's data and then demanding a ransom, can participate in the distribution of the ShurL0ckr virus.

Currently, ShurL0ckr is capable of bypassing the most of the anti-virus engines and evading well-known cloud applications, including Google Drive and Microsoft Office 365. Several tests of Bitglass on VirusTotal have revealed that only 7% of 67 tested AV engines are able to detect and remove ShurL0ckr.

As we have already mentioned, this ransomware has already been dubbed as a new version of Gojdue, though its performance coincides with Satan ransomware. However, no matter how surprising its ability to infect cloud services seems, it uses traditional distribution techniques. Mostly, it spreads around via spam when Word attachments are filled with the malicious Macros code.

ShurL0ckr virus is hazardous regarding capabilities to lock data in the cloud. The Bitglass Threat Research Team has already provided shocking test results[3] that claim that 44% of organizations have already been infected and at least one of their clouds has been locked by this ransomware. OneDrive, Google Drive, Dropbox and other cloud services with the built-in malware protection have already been found to be vulnerable to ShurL0ckr ransomware attack.

Because of the ability to evade detection by apps and services with the in-built malware protection, ShurL0ckr virus is expected to continue spreading worldwide. The amount of the ransom demanded is not clear. It might be that hackers customize the ransom fee according to the number of files encrypted or the amount of organization.

If you fall victim to this ransomware, you should remove ShurL0ckr virus from the system at first. At the moment, there are no official decrypters for this ransomware virus. Therefore, security experts do not recommend paying the ransom. Each ransom motivates hackers for further crimes, but there's no guarantee that the victim will receive a working decryptor after the transfer.

To decrypt files encrypted by the ShurL0ckr virus, you should either use backups or employ professional data recovery tools. You can find more information on data recovery methods at the end of the post. However, make sure you perform ShurL0ckr removal first. For that, use Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware or other professional anti-malware.

There's no hundred percent protection from ransomware attack

The ransomware we are talking about in this post is disseminated using the same methods as Satan ransomware. The author of the virus distributes spam email messages with a Word file attached. Such emails are sent to diverse email clients that are chosen randomly, so no one is immune from the reception of the spam. If the potential victim tries to open the file, he or she is asked to enable Macros. If the user allows for it, the ransomware executable, which is usually named as setup.exe, is launched and the virus settled down.

Also, hackers can also distribute it via phishing or a drive-by download. Once the virus is executed, it starts encrypting files and then creates a .txt file on the desktop, which is dubbed as ransom note by the security community. It explains the background of the virus and instructs the victim to pay the ransom (usually in Bitcoins via Tor browser).

Unfortunately, the golden rule that would help people to stay protected from ransomware doesn't exist. However, we suggest people not to open suspicious email messages, do not click on fishy lookings ads while browsing or downloading unknown software. You should be careful with stand-alone .exe installers.

Remove ShurL0ckr before recovering data

The Shurl0ckr virus is currently under investigation. Up until now, ransomware hunters informed people about the risk of this new zero-day ransomware attack and warned that it's capable of evading the detection by the majority of AV engines and cloud apps,[4] including those managed by Microsoft and Google.

If you are a victim of this virus, we would not recommend paying the ransomware. Since it's a newcomer to the market, it may have many flaws that can be discovered by cybersecurity experts in the nearest future.

Before that happens, we would suggest you remove Shurl0ckr ransomware from the system. Yes, all encrypted data will be wiped out with Shurl0ckr removal, but there's a chance to retrieve personal information from backups, Volume Shadow Copies or previous Windows Versions.
