How did the Dkrf ransomware get on my computer?

The Dkrf ransomware spreads by posting links to get hacked programs or games. They keep their eye on all hype topics which can be chosen to spread ransomware. New games releases, new popular movies – Dkrf developers make everything to get their victims on that. One of the most popular tactics these crooks use is one-day sites with torrent downloading links. However, following the modern-day trends is not the single way these burglars utilize. Methods that have already turned into standard, such as email spamming, are likewise standard for STOP/Djvu ransomware distribution.

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

Avoiding this ransomware does not require a lot of initiative. Following the standard principles of computer hygiene will significantly decrease all risks. Remember that opening all files you get on email is not a good option. Even worse case is to enable macros in Microsoft Office documents. But it is much better to prevent the malware attack 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 anticipate, as well as when you see things like “support@amazon.com”– it is likely a legitimate e-mail. Meanwhile, stuff that tries to resemble Amazon or FedEx shipping notice, but 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.

Illegal sources of different digital things need some extra description. Breaking copyright regulation surely throws you to the danger of being fined. However, using torrent trackers or third-party websites to download “free” programs also exposes you to different malware. No one can oversee unnamed people that launch the torrent seeding or publish the hacked program version on the website with pirated program.
