Finance exec at stock exchange breached via Outlook email attack

A recent cyberattack targeted a senior finance executive at a global stock exchange, allowing hackers to access months of sensitive email communications. The attackers used legitimate Windows tools to infiltrate Microsoft Outlook and exfiltrate data, raising concerns about security practices in high-value organizations. Key findings include the attackers monitoring emails from August 2025 to February 2026 and employing sophisticated tactics to avoid detection. Security experts suggest that implementing cloud access security brokers (CASB) and data loss prevention (DLP) solutions could have mitigated the risk.
