Severity: medium · Patch status: no-fix-needed · Since 2026-08-13
In July 2026, the cloud-based business communications platform RingCentral was the target of a ShinyHunters "pay or leak" extortion campaign. The group subsequently published data they claimed was obtained from the platform, which included 1.6M unique email addresses along with names, physical addresses and phone numbers. In their disclosure notice, RingCentral advised that the incident affected "a limited portion of RingCentral customers" and that it was communicating directly with those affected. Exposed data: email addresses, names, phone numbers, physical addresses. The breach dates from Jul 27, 2026; Have I Been Pwned loaded it on Aug 13, 2026.
What to do
- If you had a RingCentral account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
