Ransomware has been a nightmare for the last 4 years. It is challenging to imagine a more dangerous malware for both individuals and businesses. The algorithms utilized in Win32/Filecoder.OLQ (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. But that virus does not do all these unpleasant things without delay – it can require up to a few hours to cipher all of your files. Hence, seeing the Win32/Filecoder.OLQ detection is a clear signal that you need to begin the clearing procedure.

Where did I get the Win32/Filecoder.OLQ?

Ordinary tactics of Win32/Filecoder.OLQ distribution are common for all other ransomware variants. Those are one-day landing sites where victims are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern method in malware spreading – you get the email that imitates some standard notifications about shipments or bank service conditions changes. Within the email, there is a malicious MS Office file, or a 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 fairly simple, however, still needs tons of awareness. Malware can hide in different places, and it is much better to stop it even before it goes into your system than to depend on an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer stays on YouTube videos. That can keep you a lot of money and time which you would certainly spend while looking for a solution.
