Ransomware has been a horror story for the last 4 years. It is hard to imagine a more harmful virus for both individual users and organizations. The algorithms utilized in FileRepMalware [Boot] (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 actually exists, and possibly will exist. But that malware does not do all these bad things immediately – it may require up to a few hours to cipher all of your files. Therefore, seeing the FileRepMalware [Boot] detection is a clear signal that you have to start the clearing procedure.

Where did I get the FileRepMalware [Boot]?

Ordinary ways of FileRepMalware [Boot] spreading are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a relatively new method in malware distribution – you receive the e-mail that imitates some normal notifications about shipments or bank service conditions updates. Inside of the email, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite easy, but still requires tons of attention. Malware can hide in various places, and it is much better to prevent it even before it goes into your system than to rely on an anti-malware program. General cybersecurity awareness is just an important thing in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of time and money which you would spend while trying to find a solution.
