Ransomware has actually been a nightmare for the last 4 years. It is difficult to imagine a more hazardous malware for both individuals and businesses. The algorithms utilized in Ransom:AutoIt/Genasom.B (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these unpleasant things without delay – it may take up to a few hours to cipher all of your files. Thus, seeing the Ransom:AutoIt/Genasom.B detection is a clear signal that you should start the removal process.

Where did I get the Ransom:AutoIt/Genasom.B?

Routine tactics of Ransom:AutoIt/Genasom.B injection are standard for all other ransomware variants. Those are one-day landing websites where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new strategy in malware spreading – you get the email that imitates some routine notifications about shipments or bank service conditions updates. Within the email, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks quite simple, but still requires tons of awareness. Malware can hide in various spots, and it is much better to stop it even before it goes into your system than to trust in an anti-malware program. Simple cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a computer remains on YouTube videos. That may save you a great deal of money and time which you would certainly spend while looking for a solution.
