A ransomware-as-a-service virus, calling itself DotRansomware has appeared on the deep web. The virus has been created in English and is highly modifiable. It also uses AES encryption algorithm to encode the files on the victims’ computers. This encryption is sophisticated and generates a unique decryption key. The virus comes with it’s custom sales page which is oriented primarily towards selling it to people who want to infect users with it. The ransomware virus uses the TOR networking system to infect various users and hence remain untraceable. In case you have been infected by DotRansomware, recommendations are to read the following material and learn what DotRansomware exactly performs and how to neutralize it and try getting back the data.

How Does DotRansomware Spread
This particular virus is advertised online to absolutely everyone who has access to some particular areas of the deep web. This means that DotRansomware may spread depending on what the cyber-criminal decides. Typically most cyber-criminals choose e-mail spam messages with deceitful content, like the example picture below shows:
Such e-mails aim to get the user to open malicious e-mail attachment which is the infection malware that downloads the payload of DotRansomware, in this hypothetical scenario.
However, there are many other methods by which this ransomware infection could infect users:
- Via fake installers or updates downloaded from shady websites.
- If the user activates a fake patch for cracking unlicensed software, usually downloaded from torrent websites.
- Via other malware that has previously infected a computer.
- Via potentially unwanted program (PUP) that aims to perform an infection via multiple different advertisements, redirects or pop-ups.
DotRansomware – Further Analysis
The virus has been uploaded on a TOR-based web page and as soon as you open it, the terms of the developers immediately become evident:
The cyber-criminals offer as much as half of the extorted money paid by the victim to the one who distributes their own version of DotRansomware. The registration process of the virus is also quite simple. All one needs to begin infecting is a BitCoin address. As tempting as it sounds, this is quite the risk and at the end, trusting cyber-criminals is never a good idea at all.
During the infection process, DotRansomware may drop multiple malicious files on the computers it compromises. The files may have different names and may be located in different Windows folders, for example:
The official file extension of the DotRansomware virus is .locked, but the ransomware may undergo some changes, it really depends on how it is configured:

Amongst the files types this virus encrypts are around 400 different files that are connected with various programs that are used on a daily basis:

These important files are rendered no longer openable and the virus also has a ransom note which can be customized. Malware researchers believe that it may be somehow connected to Unlock26 ransomware – a relatively new virus that hit the wild recently.
