Twitter Responded to Its Jack Hack by Turning Off Tweeting via Text Message

Its CEO’s account was compromised in that fashion last week

Nothing gets a quicker response from a company than its CEO being hacked, especially when that company is a social networking giant.

Twitter responded to last week’s hack of Jack Dorsey’s account by temporarily halting users’ ability to tweet via SMS.

Dorsey’s account was hacked last week and used to spread pro-Nazi and anti-Semitic messages, along with other hateful content.

Kate Conger of The New York Times reported last week that the hack was executed using messaging service CloudHopper, which enables its users to tweet via text message after linking their mobile phone numbers to their accounts.

Twitter acquired CloudHopper in April 2010.

Twitter Support tweeted Wednesday that it was temporarily turning off the ability to tweet via SMS, saying in one follow-up tweet, “We’re taking this step because of vulnerabilities that need to be addressed by mobile carriers and our reliance on having a linked phone number for two-factor authentication (we’re working on improving this),” and adding in another tweet that the feature will be reactivated soon in markets that depend on text messaging for reliable communication.
