The algorithms utilized in Win32:WannaCry-E [Trj] (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these horrible things immediately – it may require up to several hours to cipher all of your documents. Therefore, seeing the Win32:WannaCry-E [Trj] detection is a clear signal that you must begin the elimination procedure.

Where did I get the Win32:WannaCry-E [Trj]?

Routine ways of Win32:WannaCry-E [Trj] distribution are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free program, so-called bait emails and hacktools. Bait emails are a pretty modern strategy in malware spreading – you get the email that simulates some regular notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks fairly uncomplicated, however, still demands tons of focus. Malware can hide in different places, and it is better to prevent it even before it goes into your computer than to rely upon an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a solution.
