What does .pashka stand for?

Recently the newest threat has attacked a great number of personal computers. This threat is Quimera ransomware. The characteristic feature of this virus is .pashka extension, that is added to the end of the files’ names. This virus doesn’t belong to any already known family of viruses, however, it has the same features with well known ones, such as STOP(DJVU), Medusa Locker and DHARMA. As far as it’s known, this virus spreads by the means of fake installators. It’s interesting, that the creators of Quimera virus hack YouTube channels in order to promote the file, that contains this virus. However, nowadays it’s not the only way to distribute it. Hackers can also infect your computer with a remote access software, that gives them an opportunity to install Quimera virus remotely without any suspect. Moreover, they can easily spread it by the means of fake emails. Hackers often write messages, as if they are representatives of a well-known company, such as DHL, by the means of which they try to force a victim to open an infected file. On the basis of the previous statements, we strongly recommend you to have a strong antivirus protection, that can prevent a potential attack. If you are unlucky and your device is already infected with this virus, don’t try to rename .pashka files! Such modification of a file can easily damage it.

Quimera ransomware encryption process.

The Quimera ransomware encryption process can be described as a very complex one. At first the Quimera makes some changes in the Registry in order to launch itself with the next startup of an infected computer. Then it injects into a memory of another process in order to stay undetected. At the same moment it checks if it’s started in a virtual machine or not. In the end it begins the scanning process in order to find files, that can be modified. In the most cases such files are all formats of media files and documents, however, Quimera can also easily modify archives and databases. When the files are found, Quimera immediately begins to modify them and makes them unreadable. The easiest way to identify this virus is “.pashka” extension, that is added to the files’ names and ransom note, that is called “HELP_ME_RECOVER_MY_FILES.txt”. By the means of this note hackers try to force a victim to pay for the decryption services, that they offer. Unfortunately, only they can surely decrypt your files, however, there is a great number of cases, when ransoms refuse to fulfil their promises. As far as they are paid, criminals just stop all contacts with the victims. Moreover, they can even make the situation much worse. They can send you a malicious software instead of the a decryptor and easily destroy all your data. That’s why we strongly recommend you to avoid any contact with them and check your system with a powerful antivirus.
