EDA2-based ransomware is still being released, and the latest proof for this is the Anubis Ransomware, a cyber threat that uses the AES-256 encryption to lock files stored on the victim's computer. The Anubis Ransomware doesn't seem very sophisticated, and it appears that its author has not included any new features or modules that may make this EDA2-based threat more threatening than other EDA2 variants that malware researchers have already analyzed. Attacks that involve the Anubis Ransomware are fairly easy to recognize because this ransomware marks all encrypted files by adding the '.code' extension at the end of their names (e.g. 'document.txt' will become 'document.txt.code').

The ransom note that the Anubis Ransomware stores on the victim's desktop does not contain any information regarding the ransom fee or the payment method that needs to be used. The only instructions included tell users to contact 'support.code@aol.com' or 'support.code@india.com' if they want to receive decryption instructions. It is very likely that users who send a message to the attackers will be asked to pay a ransom fee via BitCoins in exchange for a decryption tool and instructions. Although this offer may tempt some users, we advise them not to send any money to the attackers since this doesn't guarantee that they'll get their data back. It is not uncommon for ransomware authors to stop responding to messages as soon as they receive the money, and there have been many cases in which ransomware operators asked for money even though they had no idea how to decrypt the files of their victims.

Previous EDA2 variants were successfully decrypted by malware experts, and there's a significant chance that this may happen with the Anubis Ransomware as well. That's why the best thing victims of the Anubis Ransomware can do is to use a reliable anti-malware software suite to erase the ransomware from their computers. The encrypted files should be preserved, as they will be required if a free decryption utility becomes available.
