Twitter has temporarily disabled a feature that gives its users the ability to post a tweet from their account just by sending an SMS message to the company number from their registered mobile number. Twitter CEO Jack Dorsey’s Twitter account was compromised last week when a hacker group called “Chuckling Squad” replicated a mobile phone number associated with the CEO account and abused this particular feature to post racist, offensive messages and bomb threats from it via SMS. Twitter has not provided any timeline of the reactivation of this feature.
