The hackers Syrian Electronic Army Saturday seized control of multiple CBS Twitter accounts, posting messages that redirected to malicious websites that launched drive-by attacks at browsers. Twitter responded by suspending the affected accounts and returning them to their rightful operators. Then it suspended the hacking group's own Twitter feed.
In response, the Syrian Electronic Army registered a new Twitter account at "@Official_SEA," which Twitter subsequently froze. Cue @Official_SEA3, which Twitter duly shut down, and so on.
