What is VirTool:Win32/Obfuscator.AQZ virus?

VirTool:Win32/Obfuscator.AQZ is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for receiving the decryption key.

Ransomware has been a horror story for the last 4 years. It is challenging to picture a more harmful virus for both individual users and corporations. The algorithms utilized in VirTool:Win32/Obfuscator.AQZ (generally, 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 currently exists, and possibly will exist. But that virus does not do all these bad things immediately – it may take up to a few hours to cipher all of your documents.

Where did I get the VirTool:Win32/Obfuscator.AQZ?

Routine ways of VirTool:Win32/Obfuscator.AQZ injection are usual for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty modern tactic in malware spreading – you get the email that imitates some regular notifications about deliveries or bank service conditions changes. Within the email, there is an infected 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.

Avoiding it looks pretty simple, but still needs a lot of recognition. Malware can hide in various spots, and it is much better to stop it even before it gets into your computer than to depend on an anti-malware program. Simple cybersecurity knowledge is just an important item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a great deal of time and money which you would spend while seeking a fixing guide.
