  • Specifics for variant Agent.Y
    • It drops a file with an extension of .fld. It copies the filename of the original executable file. For example, if the original executable file is randomFile.exe, it drops the file named randomFile.fld. This .fld  file is a text file containing the path for the malicious copy of itself.
    • This malware chooses a path by looking for a random folder under the Program Files folder. It then copies a random filename from the chosen folder. Files that are chosen are usually those that have an extension than is not exe. It then drops a copy of itself to that directory using the copied filename with the exe extension name.
