How did the Gcyi ransomware get on my computer?
The Gcyi ransomware spreads by posting websites to get hacked programs or games. Cybercriminals that spread this ransomware are extremely foxy, and try to stay connected with modern things. New games releases, new popular movies – Gcyi developers make whatever to get their victims on that. One of the most popular strategies these criminals use is one-day sites with torrent downloading links. Nevertheless, pursuing the current trends is not the only manner these criminals use. Methods that have already become classic, such as email spamming, are also common for STOP/Djvu ransomware spreading.
Avoiding this ransomware does not need a lot of initiative. Using the standard principles of computer hygiene will significantly decrease all risks. Bear in mind that launching all documents you receive on email is not a great habit. Even worse scenario is to allow macros in Microsoft Office files. But it is much better to prevent the malware attack at the moment when you have just opened the e-mail message. Inspecting the sender’s address can say a lot about what you can expect, and also when you see the thing like “firstname.lastname@example.org”– it is likely a trustworthy email. At the same time, stuff that tries to resemble Amazon or FedEx shipment alert, but uses the e-mail address of “email@example.com”– should 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 regulation already throws you to the possibility of being fined. However, utilizing torrent trackers or third-party sites to download “free” programs also exposes you to a wide range of malware. Nobody can control undisclosed individuals that launch the torrent seeding or release the hacked program version on the website with pirated program.
