Hi all


I have a ton of encrypted files:


  • ANNRUMBAUT0209.doc.id-5AC1C432.{mailrepa.lotos@aol.com}.CrySiS
  • cp011348.xml.id-5AC1C432.{mailrepa.lotos@aol.com}.CrySiS
  • cp011800.xml.id-5AC1C432.{mailrepa.lotos@aol.com}.CrySiS
  • ...

https://id-ransomware.malwarehunterteam.com/ doesn't give a proper result.

The email address in the filename has become invalid, so no way to contact the guy.


I have no decrypt txt files, the files are all on a NAS, which has been infected with a device which isn't in our network anymore.


Sample files: http://www.filedropper.com/cp011348xmlid-5ac1c432mailrepalotosaolcom



Any help much appreciated!!!

Troldesh is a crypto-ransomware variant created in Russia that appends encrypted data files with an .XTBL or .YTBL extension to the end of each filename using GPG Cryptography. In later versions, Kaspersky lab advises the malware added the infected computer’s ID and then the .xtbl extension to the file name like this example... ArSxrr+acw970LFQw.043C17E72A1E91C6AE29.xtbl. According to ESET, the newer variants append an additional .<id-random>.<email>.xtbl extension.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion noted by al1963...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion, this topic is closed.
