.Anonfive File Virus – Specifics

The .Anonfive file virus is ransomware. According to the analysis of the malware researcher Karsten Hahn, the virus is a variant of HiddenTear. The extension .anonfive will get appended to all files that become locked after the encryption process is finished.

The Anonfive ransomware could make entries in the Windows Registry to achieve some kind of persistence, and might even launch or repress processes inside the Windows operating system. Some of these entries are designed in a way that will start the virus automatically with every booting of Windows.

The ransom note will be placed inside a .txt file after the encryption process is set and done. The file with the ransom note is called READ_IT.txt. It should contain very strict instructions for payment and file recovery.

The note will read something in the lines of the following:

Anonfive was Encrypt your File
Send 50 USD BTC Address 1BYT6TBwwJzr2vXXkhz918VvkB7yb3MgAD
[some email is given for contact]

The ransomware is reported to be a HiddenTear/EDA2 variant by the malware researcher Karsten Hahn. You can read more about the HiddenTear/EDA2 open-source project from the corresponding article in the blog.

The note of the Anonfive ransomware the cybercriminal behind the virus demands 50 US dollars to be paid out as ransom in the form of BitCoins. A Bitcoin address is provided and an e-mail address is given as a contact. However, you should NOT under any circumstances pay the crook behind this virus, neither should you use the provided e-mail for contact. Your files may not get restored, and nobody could guarantee it. Furthermore, giving money to the criminal will likely just be the motivation needed for distributing more ransomware viruses or doing other criminal activities.

→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
