.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,

All affected files are marked with the .jaff file extension. The displayed ransomware note reads the following message:
jaff decryptor system
Files are encrypted!
To decrypt flies you need to obtain the private key.
The only copy of the private key, which will allow you to decrypt your files, is located on a secret server
in the InternetYou must install Tor Browser: https://www.torproject.org/download/download-easy.html.en
After installation,run the Tor Browser and enter address: http://rktazuzi7hbln7sy.onion/
Follow the instruction on the web-site.
The hackers maintain a payment gateway located on the TOR anonymous network. When the site is opened by the computers victims they are asked to enter their unique machine infection ID which is generated during the encryption phase.
.Jaff File Virus Distribution Tactics
One of the primary distribution methods associated with the .jaff file virus is the large-scale email spam campaign. The criminals behind the threat operate a dangerous network that spreads message containing the .jaff file virus. Examples include the following:
- 116.103.236.119 [email protected] Your Invoice # 07889 invoice.pdf text.txt
- 176.217.8.122 [email protected] Your Invoice # 22554 invoice.pdf text.txt
- 45.248.37.247 [email protected] Your Invoice # 50501 invoice.pdf text.txt
- 49.244.17.138 [email protected] Your Invoice # 739159 invoice.pdf text.txt
- 213.147.120.183 [email protected] Your Invoice # 98263 invoice.pdf text.txt
Notice that the hackers use double extensions to fool the users that the files are a simple text document.
A prior email spam attack campaign included randomly-generated file attachments sent to the victims through hacked servers and botnets.
Other ways of getting infected with the .Jaff file virus include the use of modified software installers. They are usually legitimate copies that have been modified to include the malicious code. 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. In addition it harvest sensitive such as any stored account credentials, cookies, passwords, bookmarks, settings and etc.
Hacker-controlled ad networks and related redirects can also lead to a .Jaff file virus infection. The ad networks that are operated by the computer criminals both distribute the samples and also generate income if the users interact with them.
Another possible way of delivering the .Jaff file virus is by launching direct hacker intrusion attacks. The criminals use automated vulnerability testing frameworks against outdated software running on the victim computers. Security experts recommend all users to always patch their applications to the latest available versions.
