How does .abc virus operate?

There have been lots of various discussions related to .abc file extension virus. The most important thing is that security experts haven’t found the developers of this ransomware.[1] It has been declared that this virus is a member of notorious family of ransomware which is known for TeslaCrypt and Alpha Crypt. If these claims are true, victims having .abc ransomware virus on their computers are in a big trouble because this threat makes itself active as soon as it enters the system. Once there, it starts looking for the most-used files on victim’s computer. After finding each of these files, it encrypts them with the help of RSA-2048 encryption algorithm.[2] You can find your encrypted files among the safe ones by looking at their extensions. According to the latest reports, this ransomware can append these file extensions: .exx, .xyz, .zzz, .aaa, .abc. Also, it drops Restore_files.txt file on computer’s desktop that explains about the recovery of the encrypted files. Unfortunately, there is no chance to guess the code needed for the decryption of affected files. The virus seeks to convince its victims that the only way to recover their files is to pay the ransom which is equal to 0.7 BTC (or $300). Beware that there is no guarantee that, after making the payment, you will get a private key that you need.[3] According to the most of security experts, you need to remove .abc virus first. Once you do so, make sure you restore your files with the help of recovery instructions or try TeslaCrypt decrypter released by Eset.[4]
