AlphaBetaCrypt ransomware removal instructions

What is AlphaBetaCrypt?

AlphaBetaCrypt ransomware is designed to encrypt victim's files, change their filenames and create a text file (ransom note). It renames all files by appending the ".CRYPT" extension (e.g., it renames "1.jpg" to "1.jpg.CRYPT", and so on), and creates the "README_README_README_README.txt" text file. This file contains instructions on how to contact AlphaBetaCrypt's developers and some other information.

As stated in the "README_README_README_README.txt" file, victims should contact cyber criminals via betasup@mail.ee or betasup@cock.li and provide the appointed personal identifier. After that they will receive a Bitcoin wallet address that should be used to pay a ransom. AlphaBetaCrypt's developers promise to send a decryption tool after a payment. Also, it stated that attempts to uninstall AlphaBetaCrypt, rename encrypted files or decrypt them with some other software will damage encrypted data irreversibly. Unfortunately, most programs of this type (including AlphaBetaCrypt) encrypt files with strong encryption algorithm and it is impossible to decrypt them without a tool (or tools) that only cyber criminals who designed ransomware have. Another problem is that ransomware developers cannot be trusted, quite often victims who pay a ransom get scammed. In other words, cyber criminals do not send decryption software and/or key even after a payment. In most cases the only way to recover files for free/without having to use tools that only cyber criminals can provide is to restore them from a backup. Also, it is worth mentioning that files remain encrypted even after removal of ransomware. However, by removing ransomware from the operating system victims prevent further encryptions/data loss.

More examples of ransomware-type software are Reha, Topi and Kristina (OnyxLocker). Typically, these programs encrypt files and display and/or create some ransom note. In most cases the only main differences are size of a ransom and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data. Unfortunately, it is impossible to decrypt files without the right tools and cyber criminals behind a particular program are the only ones who can provide them. It is possible to decrypt files without their help (and monetary loss) only when ransomware is not finished (contains some bugs, flaws, and other vulnerabilities). However, it does not happen often and victims can restore their data for free only if they have a backup. That is why it is important to always have data backed up and keep it on a remote server and/or unplugged storage device.

How did ransomware infect my computer?

Usually cyber criminals spread ransomware (and other malware as well) via spam campaigns, fake software updaters, untrustworthy software download channels, unofficial software activation tools and Trojans. Very often they send emails that contain malicious attachments or website links that are designed to download some malicious file. Attachments in their emails usually are Microsoft Office documents, archive files (like ZIP, RAR), PDF documents, JavaScript files, and executable files like .exe. If opened, those attachments usually install some malicious program. The same applies to files that get downloaded through links that are included in their emails. People who attempt to update software with some unofficial tools risk to cause installation of some malicious program. Also, tools of this could be designed to exploit bugs, flaws of some outdated software as well. Untrustworthy software download channels can be used as tools to spread malware too. Quite often cyber criminals use Peer-to-Peer networks (like torrent clients, eMule), various free file hosting, freeware download websites, third party downloaders and other similar channels for that. They upload infected files and hope that someone will download and open them. When opened/executed, those files infect systems with some high-risk malware. Unofficial software activation/"cracking" tools supposed to bypass paid activation of licensed software for free. Nevertheless, instead of doing that these tools often download and install ransomware or some other malicious software. Trojans are programs that often are designed to spread other malware. If a computer is infected with a Trojan, then it is very likely that it will cause additional damage (installation of malware).

How to protect yourself from ransomware infections?

We strongly recommend not to open attachments (and web links) that are included in irrelevant emails, especially if those emails are received from unknown, suspicious addresses. Installed software should be updated only through implemented functions, tools that are designed by official developers. All files should be downloaded from official websites and via direct links. Other tools or sources that we mentioned in the paragraph above should not be trusted and may be used to proliferate malicious software. All installed software must be activated properly. It is not legal to activate software through various third party, unofficial tools. Also, these tools can be designed to install malicious software. One more important thing is to occasionally scan the operating system for threats with a reputable antivirus or anti-spyware suite and always keep that software up to date. If your computer is already infected with AlphaBetaCrypt, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
