The attacker behind the recent Twilio data breach may have accessed phone numbers and SMS registration codes for 1,900 users of the popular secure messaging app Signal.
“Among the 1,900 phone numbers, the attacker explicitly searched for three numbers, and we’ve received a report from one of those three users that their account was re-registered,” the Signal team shared on Monday.
What happened?
Twilio provides phone number verification services services (via SMS) for Signal.
