Ransomware has actually been a horror story for the last 4 years. It is difficult to realize a more dangerous virus for both individual users and organizations. The algorithms used in Ransom:AutoIt/Lokmwiz (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 actually exists, and possibly will exist. But that virus does not do all these bad things without delay – it may take up to a few hours to cipher all of your files. Hence, seeing the Ransom:AutoIt/Lokmwiz detection is a clear signal that you should begin the elimination procedure.

Where did I get the Ransom:AutoIt/Lokmwiz?

Ordinary tactics of Ransom:AutoIt/Lokmwiz distribution are basic for all other ransomware variants. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively modern method in malware spreading – you receive the email that imitates some routine notifications about shippings or bank service conditions changes. Inside of the e-mail, 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.

Preventing it looks fairly easy, but still needs tons of awareness. Malware can hide in various spots, and it is better to stop it even before it invades your computer than to depend on an anti-malware program. Common cybersecurity knowledge is just an important item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may keep you a great deal of time and money which you would spend while searching for a fix guide.
