In other words, how did this Amnesia ransomware variant sneak into your system to encrypt all your data?
The most popular methods of distributing cryptoviruses such as .crypt virus file include pirated software, landing on scam pages, and malicious email attachments. Let’s examine the most widespread scenarios of getting a ransomware infection:
- 1.Victims downloaded a suspicious program from an untrustworthy torrent or freeware site.
Keep in mind that most torrent and free download websites may contain unverified files that may expose you to risks of Trojans and ransomware. Why is that? If you have downloaded a trojanized application (an application which contains a hidden Trojan component), it may have contained a backdoor, later utilized by ransomware operators in their campaigns.
- 2.Victims have opened a malicious email attachment sent to them by a seemingly verified sender.
Malicious spam) operators have their ways to trick you into opening an infected email attachment. Even big companies may fall victims to malware and ransomware, and this usually happens when an employee opens a malicious email attachment and executes the attached file.
The attached file may look like a regular document, but in truth, it contains malicious code that could compromise your system severely. Opening an unexpected email attachment is very dangerous and shouldn’t be done without additional verification.
