In some cases, Ransom:Win32/MegaCortex.A can also prevent the setup of anti-malware programs.

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Sample contains Overlay data;
  • Dynamic (imported) function loading detected;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;

Ransomware has actually been a horror story for the last 4 years. It is challenging to imagine a more dangerous virus for both individuals and businesses. The algorithms used in Ransom:Win32/MegaCortex.A (generally, 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 currently exists, and possibly will exist. But that virus does not do all these unpleasant things immediately – it can require up to several hours to cipher all of your files.

Where did I get the Ransom:Win32/MegaCortex.A?

Typical methods of Ransom:Win32/MegaCortex.A distribution are common for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a quite modern strategy in malware distribution – you get the e-mail that simulates some normal notifications about shipments or bank service conditions shifts. Within the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

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

Avoiding it looks quite simple, but still needs a lot of attention. Malware can hide in various places, and it is better to stop it even before it invades your system than to depend on an anti-malware program. Basic cybersecurity knowledge is just an essential item in the modern-day world, even if your interaction with a computer remains on YouTube videos. That may keep you a lot of money and time which you would spend while searching for a fix guide.
