FBI Alert Outlook OneDrive Vulnerability Exploited in Corporate Data Heists
The FBI has issued a stark warning to corporate executives: a sophisticated cyber-espionage campaign is actively using Outlook and OneDrive as vectors to exfiltrate sensitive data. This is not a routine threat. We have confirmed with security contacts that the operation bypasses standard MFA by intercepting authentication tokens via a new strain of password-stealing malware, masquerading as routine Microsoft update notifications. Initial reports indicate Fortune 500 legal and finance departments are the primary targets, with data streams being silently copied to external servers within hours of initial compromise. The agency advises immediate adoption of hardware-based security keys and a complete review of app consent permissions. Latency in response now directly correlates with irreparable reputational damage.
