The malware then tries to communicate with the other peers via the Overnet P2P protocol on how to proceed. It is basically downloading other component/configuration details via the P2P network. The malware has the ability to do the following:

  • Harvest e-mail addresses but avoid those that contain certain strings
  • Download messages to be used in spam
