Ransomware has been a headache for the last 4 years. It is challenging to realize a more harmful malware for both individual users and organizations. The algorithms utilized in Trojan:Win32/Ymacco.AB92 (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy actually exists, and possibly will exist. However, that virus does not do all these bad things immediately – it can require up to a few hours to cipher all of your files. Thus, seeing the Trojan:Win32/Ymacco.AB92 detection is a clear signal that you need to begin the removal process.

Where did I get the Trojan:Win32/Ymacco.AB92?

Common tactics of Trojan:Win32/Ymacco.AB92 distribution are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a pretty new tactic in malware distribution – you receive the email that mimics some regular notifications about shipments or bank service conditions updates. Within the e-mail, there is a malicious MS Office file, or a web 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 quite easy, however, still requires a lot of attention. Malware can hide in various spots, and it is better to prevent it even before it goes into your system than to rely upon an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That can save you a great deal of money and time which you would certainly spend while looking for a solution.
