Qlocker ransomware automated removal and data recovery If you are a QNAP user and the Qlocker nasty is holding your data for ransom, try the following methods to clean the device and get those files back. The service provider has released patches for all loopholes it could identify when investigating this stratagem, so it’s now up to users to apply these updates and stay protected. The most-exploited weakness is an SQL vulnerability documented as CVE-2020-36195. The apps exposed to easy infiltration include the Media Streaming Add-on, Multimedia Console, and Hybrid Backup Sync.
.7Z FILE EXTENSION VIRUS SERIES
The Qlocker crew uses a series of security gaps in QNAP components to gain original foothold in NAS devices. However, the threat actors fixed this bug shortly. Replacing a lowercase letter to uppercase in the “transaction ID” on Qlocker Tor site made the system misinterpret the event as if it were a new payment, when it was actually an edited string for a victimized user who had previously submitted the ransom. And yet, white hats were able to decrypt the keys for about 50 victims via a loophole in the criminals’ payment confirmation routine.
.7Z FILE EXTENSION VIRUS PASSWORD
It means that the odds of recovering these items without the criminals-owned unique password is close to fiction. This predatory program employs a cipher provided by 7zip to achieve a rock-solid degree of data scrambling. It’s about a dramatic change in the structure of every file at a deep level due to dodgy use of cryptography.

To get rid of the threat, you need to purchase the full version of the anti-malware tool:Īs is the case with any ransomware attack, the biggest issue with the Qlocker infection isn’t about the filename tweaking or scary-looking ransom demands. Free scan determines if your system is infected.
.7Z FILE EXTENSION VIRUS PC
Scan your PC with Combo Cleaner for Windows to detect all files related to Qlocker ransomware. Mass-scanning for devices with known QNAP NAS vulnerabilities, SQL injection Moves files to encrypted archives and drops a ransom note demanding 0.01 BTC (about $500) for the decryption key Fellow-extortionists from other groups must be feeling jealous right now. Pair the profit with the fact that the felons didn’t have to invest a penny in creating a separate ransomware program and are using an open-source archiver instead, and the whole extortion model gets really offbeat and crafty.

Note that this was just five days since the campaign began. Security researchers were able to track down the payments based on BTC addresses in ransom notes – they found that the malefactors received at least $260,000 as of April 24, 2021. In the Qlocker scenario, though, the relatively small ransom plays into crooks’ hands, as users are less hesitant when deciding whether or not to pay. This is interesting because most ransomware actors want much bigger amounts reaching thousands or tens of thousands of dollars per device. The site adds clarity to the blackmail by demanding 0.01 Bitcoin (worth about $500 at the time of writing) for the recovery password. Qlocker also drops a ransom note that explains what happened and provides an ID that must be entered to log into a specified Tor payment page uniquely associated with the victim.
.7Z FILE EXTENSION VIRUS ARCHIVE
Once this stage is completed, users cannot open their files that were moved into password-protected archive entities. Tor payment page used by Qlocker ransomwareĪccording to victims’ observations, the only conspicuous red flag is that numerous instances of the 7z process are visible in the Resource Monitor utility during the attack. With a fairly strong cryptographic algorithm being part of 7zip feature set, the target items undergo unauthorized encryption, which in turn allows Qlocker operators to set an ultimatum and demand money for decrypting files that suddenly became appended with the *.7z extension and, worst of all, inaccessible. The damage in this case goes beyond password-protecting victims’ files. The gang in charge has been exploiting vulnerabilities in several components of the QNAP network-attached storage (NAS) infrastructure to infiltrate the corresponding devices and remotely run the 7zip archive application to lock down data. An outbreak of a new unusual ransomware strain called Qlocker has demonstrated that cyber extortionists are good at outsmarting traditional security mechanisms and don’t mind taking shortcuts.
