What is FASTBOB ransomware? And how does it carry out its attack?
FASTBOB ransomware is a file-encrypting malware. Based on the analysis done by security experts, it appears that this new crypto-malware is a variant of FASTBOB ransomware. This new variant uses a .FASTBOB extension in marking its encrypted files, hence the name.
The instant it starts to carry out its attack, it drops its malicious payload in the system and uses it to establish a connection to a remote server and download more malicious files. It then uses the malicious files to make changes in the system such as creating and modifying entries in the Windows Registry to allow the malware to run on every system boot automatically. After that, it starts the encryption using both the AES 128-bit and RSA 2048-bit encryption algorithm. Once the encryption is completed, it adds the .FASTBOB extension to each one of the locked files. In addition, it also opens a file named “#_#FASTBOB_README#_#.rtf” which contains the following content:

If you are one of the victims of this crypto-malware, paying the ransom demanded by creators of this threat is definitely not advised as you will only add fuel to the fire by giving them what they want. These crooks are not to be trusted and besides, there is no guarantee that they will really give you the encryption key or decryption software used to restore the encrypted files. The best thing you can do is to try other recovery options without spending a cent rather than give in to their whims.
How does FASTBOB ransomware proliferate?
Just like its predecessor, FASTBOB ransomware proliferates using malicious spam emails. Crooks behind this threat attach an infected file to emails. The infected file may be a ZIP file, PDF file, an executable file or a document with macro scripts used to launch FASTBOB ransomware in the targeted machine. Aside from spam emails, the malicious payload of this threat might also be distributed via fake installers, games and so on. Thus, you need to always practice caution when downloading anything from the internet.
