Sub Seven is back after hiatus

Summary: A July 31, 2009 entry on www.subseven.org announced that development of the SubSeven backdoor had resumed, with mobman - who wrote the first version in 1999 - saying work on a new version 2.2 had begun and would be called 2.3. Cisco Talos downloaded the latest build posted on the site, version 2.1.5, and ClamAV detected its server file as Trojan.SubSeven.215-srv and its client file as Trojan.Spy-50523.

Why it matters: SubSeven's return means a well-known backdoor with a decade of history is being actively revised again, and the source gives no reason for the resumed development - so the motive and the new build's capabilities remain unknown.
