Dapo Ransomware Will Make Your Files Unreadable

After examining malware samples, we discovered a new ransomware variant named Dapo. Further analysis revealed that Dapo belongs to the Djvu ransomware family, which is frequently associated with information stealers like RedLine and Vidar. Dapo encrypts data, changes file names, and generates a "_readme.txt" file containing ransom demands.

Dapo modifies file names by appending the ".dapo" extension to each file. For example, "1.jpg" would be renamed "1.jpg.dapo", while "2.png" would be renamed "2.png.dapo". The ransom note warns that the victim's files have been encrypted and can only be accessed by purchasing decryption software and a unique key. The decryption tools cost $980, but the attackers offer a 50% discount if victims contact them within 72 hours, reducing the price to $490.

The ransom note stresses that the victim will not be able to restore their files without paying the ransom. The attackers offer to decrypt one file for free and provide two email addresses, support@freshmail.top and datarestorehelp@airmail.cc, for victims to contact them.
