IntelBroker claimed responsibility for leaking Deloitte’s internal communications.
The breach occurred in September 2024, due to an exposed Apache Solr server with default login credentials, enabling unauthorized access.
The compromised data includes email addresses, internal settings, and intranet communications.
IntelBroker is linked to the BreachForums community, a hub for trading stolen data and hacking tools, and shared proof of the breach there.
BreachForums is a successor to RaidForums and continues to resurface despite law enforcement efforts to shut it down.
Apache Solr, a popular enterprise search platform, was the vulnerability point that enabled the breach.
The incident highlights the importance of securing digital infrastructures against unauthorized access.
