Reports are coming in of a systematic hack of Twitter accounts
According to Mikko Hyponnen, chief research officer with F-Secure, more than 1000 accounts on the microblogging social networking service were hacked within the space of 12 hours, each of them broadcasting the message: "Hacked by Turkish Hackers."

In a security blog posting made last night, Hyponnen said that, although the exploit mechanism is unclear, most of the compromised accounts "seem to seem to belong to Israeli Twitter users."

Infosecurity notes that the Twitter hacking methodology appears to be the same as a rash of Facebook attacks identified by fellow IT security vendor AVG around two weeks ago when its research team revealed that a rash of "political hacktivism" was appearing.
