.Jaff file Virus – All Before and After This Event

The .Jaff file virus is advanced ransomware. The main goal of the application is to hijack the victim computer and encrypt valuable user data based on a predefined list of file type extensions.

Upon infection .Jaff file virus first performs a system check. The .Jaff file virus checks if the infected machine is a real one or a virtual machine, sandbox or debugging environment. If any false machine signatures are detected it deletes itself to avoid detection. The hackers behind have built-in fingerprints that include a wide collection of the most popular tools used by both system administrators and malware researchers.

The .Jaff file virus can also disable or permanently remove all installed security solutions, including anti-virus software. This is one of the reasons why we recommend that all computer users install a quality anti-spyware product. It can effectively protect against and remove .jaff file virus samples even before they can infect the computer.

.Jaff file virus is efficient at gathering system information. It can harvest sensitive data including the computer name, the unique cryptographic machine ID, the Windows registry and browser data. This includes all stored cookies, browser history, account credentials, bookmarks and settings. The data dump can then be used by the hackers to conduct identity theft and other related crimes.

The encryption is started soon after the virus has completed all preliminary checks and has made the needed system modifications. The module targets a predefined list of target file type extensions. The captured samples process the following file types:

.xlsx, .acd, .pdf, .pfx, .crt, .der, .cad, .dwg, .MPEG, .rar, .veg, .zip, .txt, .jpg, .doc, .wbk, .mdb, .vcf, .docx, .ics, .vsc,

The hackers then distribute the executable files on compromised or fake download sites and P2P networks such as BitTorrent.

The malware can also be delivered by browser hijackers. They are malicious extensions made for the most popular web browsers: Mozilla Firefox, Safari, Google Chrome, Microsoft Edge and Internet Explorer. Upon infection they modify important setting such as the default home page, default new tabs page and default search engine.
