The algorithms used in Backdoor:Win32/Dridex.AA!MSR (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the Backdoor:Win32/Dridex.AA!MSR?

Routine methods of Backdoor:Win32/Dridex.AA!MSR injection are basic for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively modern tactic in malware distribution – you receive the e-mail that simulates some regular notifications about deliveries or bank service conditions shifts. Within the email, there is a corrupted 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 quite uncomplicated, but still needs a lot of attention. Malware can hide in different spots, and it is much better to stop it even before it goes into your system than to rely upon an anti-malware program. General cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of money and time which you would spend while looking for a solution.
