3PARA RAT is a remote access tool (RAT) programmed in C++ that has been used by Putter Panda.1

Techniques Used

  • Redundant Access - 3PARA RAT will sleep until after a date/time value loaded from a .dat file has passed. This allows the RAT to remain dormant until a set date, which could allow a means to regain access if other parts of the actors' toolset are removed from a victim.1
  • File and Directory Discovery - 3PARA RAT has a command to retrieve metadata for files on disk as well as a command to list the current working directory.1
  • Timestomp - 3PARA RAT has a command to set certain attributes such as creation/modification timestamps on files.1
  • Standard Cryptographic Protocol - 3PARA RAT command and control commands are encrypted within the HTTP C2 channel using the DES algorithm in CBC mode with a key derived from the MD5 hash of the string HYF54&%9&jkMCXuiS.1
