Greetings everyone. It is with much regret that I am writing this post. A plugin, ss-otr, was added to the third party plugins list on July 6th. On August 16th we received a report from 0xFFFC0000 that the plugin contained a key logger and shared screen shots with unwanted parties.
We quietly pulled the plugin from the list immediately and started investigating. On August 22nd Johnny Xmas was able to confirm that a keylogger was present.
But even without that you should really (!) not use Pidgin or OTR for XMPP.
