RingCentral data breach exposed info of 1.6 million accounts
The ShinyHunters extortion group stole personal information from 1.6 million RingCentral accounts after hacking the company in July, according to the data breach notification service Have I Been Pwned.
RingCentral is a cloud-based collaboration and communication platform used by over 600,000 businesses for services such as calling, messaging, and voicemail.
The company disclosed the incident on July 28, revealing that its systems were compromised following what it described as a “sophisticated social engineering campaign.”
“We have not seen any new unauthorized activity since taking these remediation efforts. To date, this incident has affected data for a limited portion of RingCentral customers, and we are communicating with affected customers directly,” it noted.
“If you are not contacted by RingCentral, you are not affected. This incident did not impact the core RingCentral platform, and our services continue to operate without disruption.”

Key Points that Matter
- Breached account data creates fuel for future voice attacks, giving threat actors information to build more convincing impersonations.
- Trusted communications platforms are increasingly attractive targets, expanding opportunities for social engineering across interconnected voice and digital channels.
- Voice Security helps break the attack chain, preventing malicious callers from exploiting stolen information to reach and manipulate employees.
