HPE disclosed that its email system was hacked by a Russia-sponsored actor called Midnight Blizzard, also Cozy Bear. In a regulatory filing, HPE reported it was notified in December 2023 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.”  During the breach, the hackers compromised “a limited number of SharePoint files as early as May 2023,” HPE’s filing stated.
