What is Jjww Ransomware

Jjww Ransomware is a conditional name, given by security experts, for the recent version of STOP/Djvu Ransomware, that appends .jjww extensions to files. STOP Ransomware is a wide-spread, long-living ransomware infection, that has been active since 2017. As it uses RSA-1024 cryptography encryption and online key (in most cases) direct decryption using released decryptors is currently not effective. However, some methods of file-recovery, provided in this article, may help you restore some of your files or even all the data. If your files were encrypted with offline key (2-3% of all cases) 100% decryption becomes possible with STOP Djvu Decryptor from EmsiSoft, featured on the page below. In general, Jjww Ransomware creates ransom note _readme.txt, that contains decryption conditions, amount of ransom and contact details. See the sample here:

The ransom note states, that cost of decryption is $980, however, it can be reduced in a half ($490), if victim pays in first 72 hours. Unfortunately, this makes many users affected by Jjww Ransomware pay the malefactors, which is NOT recommended. The matter is, often, hackers never send the promised decryption key, and paying the ransom is just a waste of money. We recommend you to remove Jjww Ransomware first, using anti-malware tools below. Once you made sure your PC is secured, you need to back up encrypted files and then use all known methods to recover the data, using instructions below. Backup is needed, if your attempts will be unsuccessful, to preserve the data for possible decryption in the future. From the technical point of view, this won’t happen soon, however, authors of the ransomware can be finally caught by police, as it happened with other ransomware families. Once there is an access to the servers, the master key can be released and all data, encrypted by STOP Ransomware restored. Please, read the guide carefully and perfrom instructions carefully. Read all the documentation and manuals provided by the vendors.
