Ransomware has actually been a nightmare for the last 4 years. It is hard to picture a more hazardous malware for both individual users and organizations. The algorithms used in Ransom:Win32/Stopcrypt!mclg (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. But that malware does not do all these terrible things immediately – it can take up to several hours to cipher all of your documents. Therefore, seeing the Ransom:Win32/Stopcrypt!mclg detection is a clear signal that you must begin the elimination process.

Where did I get the Ransom:Win32/Stopcrypt!mclg?

Typical ways of Ransom:Win32/Stopcrypt!mclg distribution are usual for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a pretty modern tactic in malware distribution – you get the e-mail that imitates some standard notifications about shippings or bank service conditions shifts. Within the e-mail, there is an infected MS Office file, or a web link which opens the exploit landing page.

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 focus. Malware can hide in different spots, and it is far better to prevent it even before it gets into your system than to rely on an anti-malware program. General cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while seeking a solution.
