Ransomware has actually been a horror story for the last 4 years. It is hard to realize a more harmful virus for both individual users and businesses. The algorithms used in VBS/Kryptik.OW (typically, 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 actually exists, and possibly will exist. However, that virus does not do all these bad things instantly – it may take up to a few hours to cipher all of your files. Therefore, seeing the VBS/Kryptik.OW detection is a clear signal that you have to start the elimination process.

Where did I get the VBS/Kryptik.OW?

Usual ways of VBS/Kryptik.OW distribution are typical for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively modern method in malware spreading – you get the email that imitates some routine notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is an infected MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks quite easy, but still demands a lot of attention. Malware can hide in different places, and it is much better to prevent it even before it goes into your computer than to trust in an anti-malware program. Essential cybersecurity awareness is just an essential thing in the modern 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.
