How did the Uihj ransomware get on my computer?

The Uihj ransomware spreads by posting websites to get hacked programs or games. Cybercriminals that distribute this ransomware are extremely foxy, and try to correspond with modern things. New games introductions, new popular films – Uihj developers make everything to get their victims on that. One of the most common tactics these crooks put to use is one-day sites with torrent downloading links. However, using the modern things is not the single manner these criminals use. Methods that have already become standard, such as e-mail spamming, are likewise common for STOP/Djvu ransomware distribution.

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

Avoiding this ransomware does not require a lot of initiative. Considering the standard principles of PC hygiene will considerably decrease all risks. Remember that starting all documents you receive on e-mail is not a good tactic. Even worse case is to allow macros in Microsoft Office files. But it is better to prevent the malware attack at the moment when you have only opened the e-mail message. Inspecting the sender’s address can point out a lot about what you can anticipate, and also when you see things like “support@amazon.com”– it is likely a legitimate e-mail. On the other hand, stuff that tries to resemble Amazon or FedEx delivery notice, however, uses the email address of “amazonspurrot1363@gmail.com”– must make you get on the alarm. Above, you can see the illustration of such a message.

Outlaw sources of different digital things need some extra description. Breaking copyright law surely throws you to the risk of being fined. However, using torrent trackers or third-party websites to download “free” programs also exposes you to different malware. Nobody can control unidentified people that launch the torrent seeding or release the hacked program version on the site with pirated program.
