EVEREST RANSOMWARE CLAIMS 90GB DATA THEFT INVOLVING LEGACY POLYCOM SYSTEMS

Summary from the TLDR InfoSec newsletter

The Everest ransomware group claimed to have exfiltrated 90GB of internal data from systems linked to Polycom, now owned by HP Inc., including engineering build environments, source code, and technical documentation for the RMX and RealPresence conferencing platforms. Evidence suggests the data originated in legacy Polycom environments from 2017–2019, predating HP's acquisition, though it remains unclear when the systems were accessed. HP Inc. has not confirmed the breach.
