Symantec has observed an interesting variation on this concept in the wild. A back door Trojan that we are calling Trojan.Grups has been using the Google Groups newsgroups to distribute commands,' writes Symantec employee Gavin O Gorman. He goes on to state that 'the Trojan itself is quite simple. It is distributed as a DLL,' and while the decrypted commands indicate it is used 'for reconnaissance and targeted attacks,' he does go on record as saying, 'It's worth noting that Google Groups is not at fault here; rather, it is a neutral party. The authors of this threat have chosen Google Groups simply for its bevy of features and versatility.'"
