Jaff is the new Ransomware

 

Jaff is the new Ransomware.  Another active threat was discovered, Jaff is a new ransomware family that appeared just days before the WannaCry outbreak.

The new family of Jaff was discovered by Brad Duncan (a security researcher). It now has a new design for the ransom note and a new WLU extension for encrypted files. Same to the first variant of Jaff, this new version continues to be spread through spam campaigns that use malicious documents to download infect computer with ransomware.

The ransomware was adding the .jaff extension to the encrypted files and requesting around 2 Bitcoin for the payment. The infection vector was .PDF files sent as attachments in spam emails.

But now the ransomware appends the .wlu extension to the encrypted files. And it uses a new note with green fonts on a dark background. The researcher also said that the ransomware creators ask for a 0.35630347 Bitcoin for the payment now.

The new ransomware attack is being spread through messages that appear to be invoices. Victims receive emails with subjects like such as Copy of Invoice 99483713 or Invoice(58-0710), and they include an evil PDF attachment.

Unfortunately, there is no any decryption tool to decrypt .wlu files that encrypted by the Jaff Ransomware. Read this article to know how to fight against ransomware.

 

To conclude, A simpler form of Ransomware will only try to trick you into believing there’s something wrong with your computer and get you to pay money to fix it. A favourite tactic that we see in those banner ads that tell you that something has infected you. Now often with those, you’ve got at least basic control over your system still. So the only real issue is that you have to deal with constant pop-ups until you find a way to get rid of the malware.
