Ransomware behavior characteristics
-
This ransomware was developed in the .NET-based VB language and employs various obfuscation techniques to complicate analysis. Key logic and strings within the code are encrypted in a static state, decrypted and executed only at runtime. This structure is a typical technique used to hinder static analysis and evade detection.
Furthermore, while some variants of the same family have been found to change the user's desktop after infection, this feature was disabled in the sample analyzed this time. This is likely due to differences in build options, the test version, or functional limitations resulting from distribution purposes.

Infection results
After encryption is complete, a guide file is created in each folder location with the name Cyborg_DECRYPT.txt, and each encrypted file is changed to < file name. extension. Cyborg1 >.
