What is COLORIT ransomware? And how does it implement its attack?
COLORIT ransomware is a data-encrypting virus discovered in April 2019. It appends a “.COLORIT” extension to its targeted files. According to security experts, it is a confirmed version of “DCRTR-WDM” ransomware although the individual or group of cyber crooks behind it is still unknown.
Once it executes its attack in the system, COLORIT ransomware will drop its malicious payload. And once its malicious payload is running in the system, it starts to alter some settings on the infected computer like the Run and RunOnce registry keys in the Windows Registry. By modifying the aforementioned keys, it can run automatically each time a user boots the computer. It also gathers information about the system and the user and send the harvested data to a remote server controlled by the attackers. After that, it will scan the system to look for files with specific formats. Once it finds them, it will encrypt them using a sophisticated encryption algorithm. Following data encryption, it releases a file named “HOW TO DECRYPT FILES.txt” which contains the ransom note stating:
“Hello, dear friend!
All your files have been ENCRYPTED
Do you really want to restore your files?
Write to our email – [email protected]
and tell us your unique ID”
It also opens another ransom note named “HOW TO DECRYPT FILES.hta” which contains the following content:
“All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail [email protected]
Write this ID in the title of your message 6f34b033fce61c65a909e1xxxxxxxxxx

If your files are encrypted by COLORIT ransomware, you must not give in to its demands as the crooks behind this threat can’t be trusted. The best way to deal with it is to terminate its malicious processes from your computer and get rid of its components and then try to restore the compromised files using an alternative method.
How is the payload file of COLORIT ransomware distributed online?
Creators of COLORIT ransomware might disseminate the payload file of this crypto-virus using spam emails. This is the primary distribution method for this kind of threat so it’s no surprise that COLORIT ransomware is also using this in spreading its payload. The malicious file may be an executable file (.exe), a PDF file or a document pretending to be sent out by a well-known company or group. So if you catch sight of any suspicious-looking or too-good-to-be-true emails, delete them right away especially if it’s only full of grammatical errors.
