Hewlett Packard Enterprise (HPE) is investigating a new data breach after a threat actor claimed to have stolen data on a hacking forum.

Hewlett Packard Enterprise (HPE) is investigating a new data breach, following the discovery of an offer on a hacking forum where a threat actor claimed to be selling the allegedly stolen data.

According to Bleeping Computer, the company has yet to find any evidence suggesting a new security breach.

The announcement was published on BreachForums by a threat actor who uses the moniker IntelBroker.

“Hello BreachForums Community. Today, I am selling the data I have taken from Hewlett Packard Enterprise.” reads the announcement published by IntelBroker. “More specifically, the data includes: CI/CD access , System logs , Config Files , Access Tokens , HPE StoreOnce Files (Serial numbers warrant etc) & Access passwords. (Email services are also included)”

The announcement also published some screenshots containing allegedly stolen HPE credentials.


IntelBroker is considered a reputable threat actor, it was linked to the breaches of DC Health Link and Volvo Cars.

Recently Hewlett Packard Enterprise (HPE) revealed that alleged Russia-linked cyberespionage group Midnight Blizzard gained access to its Microsoft Office 365 cloud-based email environment.

The attackers were collecting information on the cybersecurity division of the company and other functions.

HPE became aware of the intrusion on December 2023 and immediately launched an investigation into the security breach with the help of external cybersecurity experts.

The investigation revealed that the attackers gained access to the company environment and exfiltrated data since May 2023. The cyberspies compromised a small percentage of HPE mailboxes belonging to individuals in our cybersecurity, go-to-market, business segments, and other functions.

“On December 12, 2023, Hewlett Packard Enterprise Company (the “Company,” “HPE,” or “we”) was notified that a suspected nation-state actor, believed to be the threat actor Midnight Blizzard, the state-sponsored actor also known as Cozy Bear, had gained unauthorized access to HPE’s cloud-based email environment. The Company, with assistance from external cybersecurity experts, immediately activated our response process to investigate, contain, and remediate the incident, eradicating the activity.” reads FORM8-K filing with the U.S. Securities and Exchange Commission (SEC). “Based on our investigation, we now believe that the threat actor accessed and exfiltrated data beginning in May 2023 from a small percentage of HPE mailboxes belonging to individuals in our cybersecurity, go-to-market, business segments, and other functions.”

The investigation is still ongoing, however, the IT giant determined that the intrusion is likely linked to another attack conducted by the same APT group, of which they were notified in June 2023.

As early as May 2023, the company discovered unauthorized access to and exfiltration of a limited number of SharePoint files.
