Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more hazardous malware for both individuals and companies. The algorithms utilized in Win32/Spy.Chekafev.AB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these horrible things immediately – it may take up to a few hours to cipher all of your files. Therefore, seeing the Win32/Spy.Chekafev.AB detection is a clear signal that you must start the elimination procedure.

Where did I get the Win32/Spy.Chekafev.AB?

Usual methods of Win32/Spy.Chekafev.AB injection are basic for all other ransomware examples. Those are one-day landing sites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a quite modern method in malware distribution – you receive the email that mimics some regular notifications about shipments or bank service conditions modifications. Within the email, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly simple, however, still requires tons of awareness. Malware can hide in different places, and it is far better to prevent it even before it invades your system than to trust in an anti-malware program. Standard cybersecurity knowledge is just an essential item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a lot of time and money which you would certainly spend while looking for a solution.
