New Troldesh Ransomware July 2016 Technical Specifications
What’s New in Troldesh’s Latest Version?
- Tor functionality;
- Glyph/symbol errors on the wallpaper ransom note;
- Modified extension names for encrypted files;
- Updates in the ransom note that cover the added Tor functionality.
- New malware being downloaded to the victim’s PC – Trojan:Win32/Mexar.A;
The most notable modification in this version is the addition of Tor links. Using Tor addresses as the ransom payment method (as opposed to standard www addresses) is the current fashion among ransomware, Microsoft researchers explain.
A Tor address is now included in the ransom note, as opposed to the older Troldesh where an email address was the only way to provide decryption keys.
However, the Tor payment website is not functioning as it is reported to be down (see image above). This means that there’s no way to pay the ransom and recover the files through contacting the cyber criminals.
Other changes in the code of this new Troldesh are the “creative” file extensions – .da_vinci_code and .magic_software_syndicate.
Also, the crypto virus is now capable of encrypting even more file type categories and delivers an additional piece of malware – Mexar (Trojan:Win32/Mexar.A). This is a completely new malware, detected by Microsoft for the first time on July 7. No technical information is available at the moment, but it’s highly likely that the Trojan is an infostealer. We will update the article when we have more information.
Microsoft recently revealed that Troldesh is the tenth most active ransomware family in the past 30 days.
