Popular social media service Twitter has finally patched up a security flaw after a cyber attack that happened earlier today, sending some users over to Japanese porn websites. According to Twitter, there was no user information which was compromised, so all should be fine and dandy from now on. According to a tweet from Twitter’s safety chief at around 10:30 a.m. EDT, the attack has since been “fully patched” and hackers will find the door used to roll out the exploit closed once and for all. This isn’t the first time something like that happened as back in April 2009, a security flaw was also reported and fixed only after several attacks. Hopefully this will be the last time Twitter has its security compromised.
