OS(es) Affected: Windows


The Alphabet Ransomware is a piece of threat that may still be in development since malware researchers identified entirely different variants of the threat. Both behave in a similar fashion, but the newer version also includes an encryption algorithm that locks the victim's files and then demands a ransom payment in exchange for the decryption instructions. The other variant that was discovered just hours before the release of the crypto-threat only works as a screen locker and even provides the victim with the unlock code. The screen locker variant of the Alphabet Ransomware also includes a line that tells the victims that they have been infected by the 'debug version,' and they can find their unlock code below. Surprisingly, the author of the Alphabet Ransomware appears to be a bit more advanced in the field, since his threat uses a randomly generated unlock code, unlike recently discovered screen lockers whose unlock codes were hardcoded in the program.

Despite carrying out entirely different attacks, both variants of the Alphabet Ransomware infiltrated the system by displaying a fake Windows Update screen that victims could mistake for a legitimate one easily. Once the fake update is finished, users are greeted by a new screen, which contains the ransom message. There's a slight difference between the lock screen used by the first and second variants of the Alphabet Ransomware. The first one uses a red background, while the crypto-threat variant of the Alphabet Ransomware relies on a green background.

The A B C Of Dealing with the Alphabet Ransomware

The crypto-threat variant of the Alphabet Ransomware demands a ransom fee of 1 Bitcoin that must be sent to the Bitcoin wallet address specified in the message. The author also gives a very short deadline for the ransom fee to be paid – only 5 hours. Usually, ransomware operators give their victims 24 or more hours to complete the transaction, but the Alphabet Ransomware's message clearly states that failing to pay the ransom fee in the next 5 hours will result in the permanent deletion of the private decryption key. The author was also 'friendly enough' to leave the victim the exact time their files were encrypted so that they'll know how much time they have left to pay the ransom fee. It is understandable to be annoyed if your files were modified by the Alphabet Ransomware, but don't forget that paying the ransom fee is not the correct thing to do. The author of the Alphabet Ransomware has not left any contact details or other information, so even if you pay the ransom fee, there's no way for them to provide you with the decryption key. It is very likely that the Alphabet Ransomware is a tactic that aims not just to damage the files, but also take money from its victims. Any victims of the Alphabet Ransomware reading this post should use an anti-malware tool to remove the infected files from their computers. Then, they should backup the encrypted files in case a free decryptor becomes available. It also may be a good idea to try 3rd-party file recovery utilities that are recommended when it comes to recuperating from a ransomware attack frequently.
