The Amnesia Ransomware first surface at the beginning of May, and about a month later the original authors have released a successor dubbed the Amnesia 2 Ransomware. This new version does not appear to feature any major changes in terms of the core features of the file-locking Trojan, but it uses a different ransom message style and contents, as well as two separate extensions to mark the locked files. Users whose files have been taken hostage by the Amnesia 2 Ransomware may notice that many of their documents, images, audio files, small videos, spreadsheets, and other files have either the '.01' or '.02' extensions appended to their names. The original names of the files are not preserved so that it may be very difficult for victims to determine how much of their important data was taken hostage by the Amnesia 2 Ransomware. In addition to encrypting and renaming files, the Amnesia 2 Ransomware also makes sure to provide the victim with instructions on how to get their data back. Unsurprisingly, the road to recovery is not a free one, and users who open the 'RECOVER-FILES.HTML' will find out that the threat's authors demand a ransom sum of 0.5 BTC.

The ransom note features a contact form that also allows victims to attach one file. According to the message, the Amnesia 2 Ransomware's operators are willing to decrypt one file for free to proof that they'll restore all data as soon as they receive the money they ask for. If your data has been taken hostage by the Amnesia 2 Ransomware, then we advise you to take advantage of the offer, but it is not recommended to pay the ransom sum of 0.5 BTC. The money might be used to fund more sophisticated file-encryption Trojans, and even with one file decrypted for free, you still can't be sure that the attackers will give back the rest of your files.

The best solution when dealing with crypto-threats is to run an anti-malware tool to detect and remove all corrupted files from the computer. Sadly, due to the nature of ransomware attacks, removing the source of the problem does not recover the locked files back to their regular state. That's why it is recommended to use 3rd-party file recovery utilities and techniques to recover from the attack at least partially.
