Trojan:Win32/Wacatac.H!ml is ransomware-type malware. It looks for the documents on your disk drive, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this virus also does a ton of damage to your system.

Summarizingly, Trojan:Win32/Wacatac.H!ml malware actions in the infected system are next:

Ransomware has actually been a major problem for the last 4 years. It is hard to realize a more hazardous virus for both individuals and companies. The algorithms utilized in Trojan:Win32/Wacatac.H!ml (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these unpleasant things immediately – it may take up to several hours to cipher all of your documents.

Where did I get the Trojan:Win32/Wacatac.H!ml?

Routine ways of Trojan:Win32/Wacatac.H!ml distribution are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a pretty modern method in malware distribution – you get the e-mail that imitates some normal notifications about shipments or bank service conditions changes. Inside of the e-mail, there is an infected 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 fairly simple, however, still needs a lot of attention. Malware can hide in different places, and it is better to stop it even before it invades your PC than to rely upon an anti-malware program. Standard cybersecurity awareness is just an essential thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can save you a lot of time and money which you would spend while looking for a fix guide.
