The algorithms utilized in Trojan.Script.AI (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these bad things without delay – it can require up to a few hours to cipher all of your documents. Hence, seeing the Trojan.Script.AI detection is a clear signal that you need to start the removal procedure.

Where did I get the Trojan.Script.AI?

General methods of Trojan.Script.AI distribution are usual for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free program, so-called bait emails and hacktools. Bait emails are a quite new strategy in malware spreading – you get the email that imitates some standard notifications about shipments or bank service conditions changes. Within the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks quite easy, however, still demands a lot of attention. Malware can hide in different spots, and it is much better to stop it even before it invades your PC than to rely on an anti-malware program. Essential cybersecurity knowledge is just an essential thing in the modern world, even if your relationship 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 solution.
