Twitter warns users that something bad may have happened, possibly...

Twitter has started warning users that their accounts may have been targeted by state-sponsored hackers, but without providing any evidence to back up those claims or enable users to batten down the hatches. It is thought that only a couple of dozen account holders, including security researchers, cryptographers and activists in the west, have so far been sent the email warnings from Twitter. Just why the warnings have been sent is, frankly, something of a mystery. Including, it would appear, to Twitter itself. The emails state, in part, "At this time, we have no evidence they obtained your account information, but we're actively investigating this matter." The Twitter warning then goes on to explain, if that's the right word, "We wish we had more we could share, but we don't have any additional information we can provide at this time."
