Twitter users suddenly learned to speak Turkish on Wednesday, posting an inflammatory message in the language replete with Nazi swastikas. Among those posting the message were the Twitter accounts of Forbes magazine, the Atlanta Police Department, and Amnesty International. Twitter identified a third-party app as being to blame for the attack. Twitter did not name the app involved, but the independent Twitter Counter service soon outed itself. It’s barely four months since Twitter Counter was last hacked, an attack that resulted in postings to high-profile accounts including those of Charlie Sheen and Lionel Messi.”]
