Hackers breached cloud communications company Twilio, Vice reports. The company provides infrastructure to companies that send automated text messages to users, so the hackers had an opportunity to take over users’ accounts that were tied to their phone number on a service backed by Twilio. One such service was encrypted messaging application Signal. Signal announced approximately 1,900 users were targeted by the hackers. For those users, hackers may have registered the stolen phone numbers on their devices and intercepted text verification codes from Signal.
