Cloud communications giant Twilio, the owner of the highly popular two-factor authentication provider Authy, says that it has so far identified 125 customers who had their data accessed during a security breach discovered last week.

"We have identified approximately 125 Twilio customers whose data was accessed by malicious actors for a limited period of time, and we have notified all of them," Twilio revealed in an update to the original disclosure.

The attackers gained access to Twilio's network using credentials belonging to multiple employees, stolen in an SMS phishing attack.

After discovering the intrusion, Twilio revoked the compromised employee credentials to block the attackers' access to its systems and started notifying affected customers.

Cloudflare, whose employees also had their credentials stolen in a similar SMS phishing attack, said the attackers failed to breach its systems after their login attempts were blocked because its employees are using company-issued FIDO2-compliant hardware security keys.

Twilio also disclosed in May 2021 that it was affected by last year's Codecov supply-chain attack where threat actors trojanized the legitimate Codecov Bash Uploader tool to steal credentials and secret keys from Codecov customers.
