The Herbert Attack stamp is a stamp on Club Penguin. In order to obtain it, the player must protect the EPF mainframe from Herbert. This stamp does not have the member badge on it, however it is currently impossible for non-members to defend the system from Herbert, and if they play Herbert's level by playing it in the levels screen after the Test Bots have attacked, you won't earn the stamp.
