Ransomware has actually been a major problem for the last 4 years. It is difficult to imagine a more harmful malware for both individuals and companies. The algorithms utilized in Win32/Sepohie.G (usually, 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 virus does not do all these bad things without delay – it can require up to several hours to cipher all of your documents. Therefore, seeing the Win32/Sepohie.G detection is a clear signal that you should start the removal process.

Where did I get the Win32/Sepohie.G?

Ordinary methods of Win32/Sepohie.G distribution are typical for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free app, so-called bait emails and hacktools. Bait emails are a quite modern method in malware spreading – you receive the e-mail 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 leads to the exploit landing site.

Malicious email spam

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

Preventing it looks pretty simple, however, still demands a lot of attention. Malware can hide in various spots, and it is far better to prevent it even before it goes into your PC than to rely upon an anti-malware program. General cybersecurity awareness is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of time and money which you would spend while trying to find a solution.
