GandCrab 5.0.2 ransomware (Removal Guide) - Oct 2018 update

What is GandCrab 5.0.2 ransomware?

GandCrab 5.0.2 — yet another version of GandCrab ransomware that emerged together with three other versions

GandCrab 5.0.2 ransomware is a cyber threat that focuses on data encryption and ransom demanding.

GandCrab v5.0.2 ransomware is a malicious cryptovirus that locks data by using Salsa20 and RSA-2048 encryption algorithms. It emerged together with the GandCrab 5 and is using the same pattern using random characters to generate the file extension. To mark files that were encrypted by Gandcrab 5.0.2, the virus takes 10 random letters or less that it places at the end of each file name. According to one of our victims, his files were marked with the .bundvvi file extension, but other victims found .wrvoqvipr, and similar random characters added to their encrypted data. After this encryption^[1] procedure is finished, the virus also creates a text file which is named by using the same characters used in the extension and a word “DECRYPT.” The note is asking to pay a ransom in exchange for the decrypted files, but keep in mind that this paying the ransom doesn't guarantee that your data will be presented with Gandcrab v5.0.2 decryptor.

The ransomware virus is one of the most recent variants in the notorious ransomware^[2] family that is known to encrypt users' data and demand a hefty amount in Bitcoin as the only way to unlock them. This particular version came out on the 1st of October and has been spreading around with the help of Fallout exploit kit since then.

Immediately after the encryption process is finished, the ransomware virus generates a file with some instructions and more details about the initial attack. Since the appearance of the first variant of GandCrab family, these ransom messages have been placed in the HTML file. At the moment, the ransom note file is created as a text file. The particular GandCrab 5.0.2 ransomware creates a ransom note named as RANDOM FILE EXTENSION CHARACTERS-DECRYPT.txt and drops it on every folder that contains encoded files. It reads the following:

Ransomware developers use different tools set for distribution

Since crypto viruses are one of the most dangerous cyber threats, these techniques of distribution may vary from variant to variant and be more dangerous than you think. The most common way of spreading these cyber infections are spam email attachments containing malicious files or directs ransomware payload.

However, these few versions of ransomware in particular family of threats are known to be distributed using exploit kits and various system vulnerabilities. Fallout exploit kit, in particular, is used in this attack, alongside Adobe Flash and Task Scheduler ALPC vulnerabilities.
