What is ColdLock Ransomware
If you did not have the appropriate software to fend off ColdLock Ransomware in time, then your files might be already encrypted with the .locked extension. For example, the original 1.mp4 has been changed to 1.mp4.locked once ransomware stroke its configuration with RSA algorithms. Most of the time, decrypting files with third-parties tools is impossible and may be dangerous for them. This is why extortionists force you to buy their software by following the instructions mentioned in a file called How To Unlock Files.txt that is created after encryption. Here is what original text of the note looks like:
!!! ALL YOUR FILES ARE ENCRYPTED !!!
Your files are encrypted by RSA 2048, you are not able to decrypt it by yourself!
Told your CEO/CTO or whoever in charge write us email to restore your files.
WE WILL ONLY KEEP YOUR SECRET KEY FOR 5 DAYS, SO DON'T PULL TIME, WAITING YOUR EMAIL.
Email address: firstname.lastname@example.org
Reserved email: email@example.com
Unfortunately, buying the decryption key may put your finances under risk because cybercriminal activity cannot be trusted. Instead, delete ColdLock Ransomware to prevent further encryption and try to decrypt the affected data through the instructions below.
