Fastbk@qq.com ransomware (Removal Guide) - Decryption Steps Included

What is Fastbk@qq.com ransomware?

Fastbk@qq.com ransomware is one of the Matrix ransomware variants that appends .FASTA extension to encrypted files

fastbk@qq.com ransomware is the cyber threat that focuses on file-locking processes to have the reason for a ransom demand.

Fastbk@qq.com ransomware – the cryptovirus that is using both, AES and RSA, algorithms in data encryption. Alternatively, this virus is known as Fasta ransomware. Once this malware infiltrates the system, it finds files for the encryption and then demands the payment for an alleged decryption key. Virus developers have even been offering to test their recovery service by sending them 3 encrypted files, but you shouldn't trust these cybercriminals because fastbk@qq.com virus is one of Matrix ransomware that has been active for more than three years now. Developers have been slightly altering the primary version by releasing updated variants to make more profit from inexperienced victims. The ransom note placed in #README_FASTA#.rtf is typically stating that your files will be automatically deleted after seven days, but paying shouldn't be considered because it may lead to permanent data loss anyway. You need thorough virus removal and data recovery instead.

Fastbk@qq.com virus is the malware that can be called most dangerous because the ransomware attack involves cryptocurrency and can lead to permanent money or data loss. People behind this threat are not trustworthy. Cybercriminals only care about the payment and your files may get deleted no matter if you pay or not.^[1]

However, fastbk@qq.com ransomware is not only encrypting your files. File encoding makes your audio files, documents, photos or archives affected but there is a huge possibility of system alterations that include:

• added system files;
• altered registry;
• deleted files;
• disabled functions or programs.

If fastbk@qq.com ransomware adds or alters Windows Registry entries, it makes sure that the malicious process is launched every time your device is rebooted, this ensures persistence and difficult termination. Also, for that purpose ransomware is set to disable antivirus programs or security features on the device.

But these features are secondary and you cannot notice any of the alterations besides the main Fasta ransomware process – encryption. When the process is done, and your files get marked with the appendix, a ransom note is delivered in every folder containing encoded data. #README_FASTA#.rtf reads the following:

This lengthy Fasta ransomware developers' message states that you should contact them via fastbk@qq.com and discover the ransom amount for your files. Researchers^[2] always note that cybercriminals offers test decryption and encourages you to contact them to create a feeling of trust.

Unfortunately, fastbk@qq.com ransomware developers are well known for previous activity with Matrix ransomware and other versions. Cybercriminals can disappear immediately after the transfer and forget about the promise to restore your data.

You should remove Fasta ransomware from the system as soon as you get the ransom note or notice files marked with suspicious extension. Waiting for more than a week can lead to deleted files permanently. If ransomware does so, data recovery using software or tools becomes barely possible.

Your computer system can get infected from a malicious email attachment

Email spam campaigns get even more clever these days.^[3] Phishing campaigns can be set to deliver various malware directly or also distribute different attacks and a cocktail of malicious cyber threats. Spam emails often don't even go to the spam email box and look legitimate enough, so people open them and download attached files.

Once the document, archive or PDF is downloaded and opened on the device, malicious content can get enabled either automatically, or you press some button and allow the malicious script to launch its designed functionality. The direct ransomware can get on your device this way, or payload dropper infects the system with the virus.

The only solution when you want to avoid these infections is to clean the email box more frequent and pay more attention to emails that you receive. Well-known companies or services are not sending Order information or Invoice marked emails to people that are not using their products.
