Ransomware has been a headache for the last 4 years. It is difficult to picture a more damaging virus for both individual users and corporations. The algorithms used in Trojan-Ransom.Win32.Darkside.k (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. However, that virus does not do all these horrible things without delay – it may take up to several hours to cipher all of your documents. Thus, seeing the Trojan-Ransom.Win32.Darkside.k detection is a clear signal that you have to start the removal process.

Where did I get the Trojan-Ransom.Win32.Darkside.k?

Usual ways of Trojan-Ransom.Win32.Darkside.k distribution are usual for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free program, so-called bait emails and hacktools. Bait emails are a relatively modern method in malware spreading – you receive the email that mimics some standard notifications about shipments or bank service conditions changes. Within the email, there is an infected 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 fairly simple, but still demands tons of recognition. Malware can hide in various spots, and it is much better to stop it even before it invades your computer than to depend on an anti-malware program. Standard cybersecurity knowledge is just an essential item in the modern world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of time and money which you would spend while searching for a solution.
