How did the Tyos ransomware get on my computer?

The Tyos ransomware spreads by posting websites to get hacked programs or games. They keep their eye on all buzz themes which can be used to spread ransomware. New games introductions, new popular movies – Tyos developers make whatever to get their victims on that. Some of the most popular tactics these criminals put to use is one-day websites with torrent downloading links. However, using the contemporary trends is not the single tactic these crooks utilize. Ways that have already turned into classic, such as email spamming, are likewise ordinary for STOP/Djvu ransomware spreading.

The example of email spamming that may lead to Tyos ransomware injection

Preventing this ransomware does not require a lot of initiative. Using the standard rules of PC hygiene will noticeably decrease all hazards. Keep in mind that starting all files you get on email is not a good option. Even worse situation is to allow macros in Microsoft Office files. But it is far better to stop the malware intrusion at the moment when you have just opened the email message. Examining the sender’s address can say a lot about what you can anticipate, as well as when you see things like “support@amazon.com”– it is likely a genuine e-mail. At the same time, stuff that tries to look like Amazon or FedEx delivery alert, however, uses the e-mail address of “amazonspurrot1363@gmail.com”– need to make you get on the alarm. Above, you can see the example of such a message.

Illegal sources of different digital things require some extra explanation. Violating copyright policy already throws you to the risk of being fined. Nonetheless, utilizing torrent trackers or third-party sites to download “free” programs also exposes you to different malware. Nobody can regulate anonymous people who start the torrent seeding or publish the hacked program version on the website with pirated software.
