How did the Jjll ransomware get on my computer?

The Jjll ransomware spreads by posting links to download hacked programs or games. Cybercriminals that spread this ransomware are very tricky, and try to keep in touch with the latest things. New games releases, new popular films – Jjll developers make whatever to get their victims on that. Some of the most popular strategies these burglars use is one-day sites with torrent downloading links. Nonetheless, pursuing the contemporary trends is not the only tactic these burglars use. Options that have already become classic, such as e-mail spamming, are likewise usual for STOP/Djvu ransomware spreading.

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

Preventing this ransomware does not require a lot of initiative. Considering the standard principles of computer hygiene will noticeably decrease all hazards. Keep in mind that opening all files you get on email is not a good tactic. Even worse case is to enable macros in Microsoft Office files. However, it is better to stop the malware intrusion at the moment when you have only opened the e-mail message. Inspecting the sender’s address can say a lot about what you can expect, as well as when you see the thing like “support@amazon.com”– it is likely a legitimate email. Meanwhile, stuff that tries to look like Amazon or FedEx shipment notice, but uses the email address of “amazonspurrot1363@gmail.com”– should make you be on the alarm. Above, you can see the illustration of such a message.

Illegal sources of various digital things need some additional description. Violating copyright law surely exposes you to the danger of being fined. Nonetheless, using torrent trackers or third-party sites to download “free” programs also exposes you to a wide range of malware. Nobody can control undisclosed people that launch the torrent seeding or publish the hacked program version on the website with pirated program.
