Hackers gained access to the email account of a senior executive at a major global stock exchange and exfiltrated data for months.
The attack, investigated by Broadcom’s Symantec and Carbon Black threat-hunting team, began in October 2025, and the threat actor retained access to the compromised Outlook mailbox until March 2026. The security experts estimate that the dwell time was roughly 150 days.
The goal of the operation was most likely espionage, but Symantec and Carbon Black did not share any information about who may have been behind the attack or which stock exchange was targeted.
