The AES-256 or RSA-1028 cipher it uses to cipher the files is not decryptable with contemporary computers. Even quantum computers that already exist will spend thousands of years to brute force the decryption key.

It [ciphers all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera.

How did the Jjww ransomware get on my computer?

The Jjww ransomware spreads by placing links to get hacked programs or games. Cybercriminals who distribute this ransomware are pretty tricky, and aim to keep in touch with current things. New games releases, new popular movies – Jjww creators make everything to get their victims on that. One of the most popular methods these burglars apply is one-day websites with torrent downloading links. However, pursuing the current trends is not the only way these crooks use. Options that have already turned into classic, such as email spamming, are also standard for STOP/Djvu ransomware spreading.

Malicious email spam
The example of email spamming that may lead to Jjww ransomware injection

Preventing this ransomware does not need a lot of initiative. Using the standard rules of PC hygiene will noticeably minimize all hazards. Keep in mind that launching all files you get on e-mail is not a good tactic. Even worse situation is to allow macros in Microsoft Office documents. But it is far better to avoid the malware attack at the moment when you have just opened the e-mail message. Checking the sender’s address can say a lot about what you can anticipate, and when you see the thing like “support@amazon.com”– it is likely a genuine e-mail. At the same time, stuff that tries to appear like Amazon or FedEx shipment alert, but uses the email address of “amazonspurrot1363@gmail.com”– need to make you be on the alarm. Above, you can see the example of such a message.

Illegal sources of different digital things require some additional explanation. Violating copyright law already throws you to the chance of being fined. However, utilizing torrent trackers or third-party websites to download “free” programs likewise exposes you to different malware. Nobody can oversee undisclosed people that launch the torrent seeding or release the hacked program version on the website with pirated software.
