What is Sodinokibi Ransomware

Sodinokibi Ransomware (a.k.a. BlueBackground Ransomware or REvil Ransomware) is disruptive cryptovirus, that encrypts user data using Salsa20 algorithm with the ECDH-based key exchange method, and then requires a ransom around 0.475–0.950 BTC to return the files. In other words, if the amount is set at $2500, then without paying within 7 days, it doubles to $5000. It appeared in April 2019 for the first time. Since then, security experts distinguish the following versions:

  • Sodinokibi Ransomware (initial version 1.0 from 23rd of April 2019)
  • Sodinokibi Ransomware (version 1.0b from 27th of April 2019)
  • Sodinokibi Ransomware (version 1.0c from 29th of April 2019)
  • Sodinokibi 1.1 Ransomware (from 5th of May 2019)
  • Sodinokibi 1.2 Ransomware (from 10th of June 2019)
  • Sodinokibi Ransomware (unclassified version with a modified ransom note from 8th of July 2019)

In the beginning, up to most recent versions, malware used following template for ransom note: {random-alphanumerical-sequence}-readme.txt, where {random-alphanumerical-sequence} is randomly generated set of letters and numbers used for users identification. This set is also used to modify extensions of affected files. Then, the virus started to utilize the following pattern: {random-alphanumerical-sequence}–HOW-TO-DECRYPT.txt. In the box below you can see an example of such file.
