Ransomware has actually been a major problem for the last 4 years. It is difficult to realize a more damaging virus for both individuals and companies. The algorithms utilized in W32.Tempedreve.A5 (typically, 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 currently exists, and possibly will exist. But that malware does not do all these horrible things instantly – it may require up to a few hours to cipher all of your files. Thus, seeing the W32.Tempedreve.A5 detection is a clear signal that you should start the removal process.

Where did I get the W32.Tempedreve.A5?

Usual tactics of W32.Tempedreve.A5 spreading are common for all other ransomware variants. Those are one-day landing sites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a quite new strategy in malware distribution – you receive the e-mail that imitates some standard notifications about shippings or bank service conditions changes. Within the email, there is an infected 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.

Avoiding it looks quite uncomplicated, but still requires a lot of recognition. Malware can hide in different spots, and it is much better to stop it even before it gets into your computer than to trust in an anti-malware program. Essential cybersecurity knowledge is just an essential thing in the modern world, even if your interaction with a PC stays on YouTube videos. That can save you a great deal of money and time which you would spend while looking for a solution.
