Additionally, it is important to remove the ransomware from the infected devices to avoid further data loss. Paying a ransom does not necessarily ensure that the attackers will uphold their end of the deal and is thus not recommended. Typically, decryption of files is only possible with tools possessed by the cybercriminals who launched the ransomware attack.

In the event of a ransomware attack, victims are often left with no choice but to pay the attackers for the decryption of their data unless they possess a copy of their files or can find a third-party decryption tool. It says that the encryption method used is RSA, and the encryption and decryption keys are different. The note promises that after the email is sent, the requirements for the decryption process will be provided, along with the password itself and a sample virus into which the password must be entered. The ransom note says that all of the victim's files have been encrypted, and an email must be sent to with the text 'Расшифровки Имя паразора: n40vU5uS' and to regain access to files. Thus, victims who do not have this language installed on their computers see gibberish text. Screenshot of files encrypted by this ransomware: DrWeb' extension to filenames, displays an error pop-up window and creates the ' КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt' file (a ransom note).Īn example of how DrWeb modifies filenames: it changes ' 1.jpg' to ' 1.jpg.DrWeb', ' 2.png' to ' 2.png.DrWeb', and so forth. Our malware researchers discovered DrWeb during an analysis of malware samples submitted to the VirusTotal website. Portable Defraggler lets you analyze and defragment either individual files and folders, or the whole computer hard drive, all in a nicely designed user interface.DrWeb is ransomware belonging to the Xorist family. Overall Portable Defraggler is a great alternative to Windows' built-in defrag tool, with great customization tools - though it can be a bit slow. One little detail missing, however, was the ability to minimize it to the system tray. Portable Defraggler can be set to turn the computer off once the disk has been defragmented, and also lets you schedule new analyses in the future. You can also create a personal list of all the files and folders that should be excluded from the analysis. You can set your own rules for Quick defrag, customize the Drive Map by choosing a design and setting the blocks' color and size. Another good thing about Portable Defraggler is its customization options.
