Security Flaws in Key Defense Project Trigger Palantir Stock Plunge

Army Report Reveals Systemic Security Issues

Palantir shares faced a severe downturn on Friday, plummeting over seven percent following revelations about critical security vulnerabilities in a major military project. The defense technology company’s most significant client, the U.S. military, identified fundamental weaknesses in a battlefield communication network that Palantir helped develop.

A newly released internal assessment from the U.S. Army exposed what it classified as “very high security risks” within the combat communication system. Military officials specifically highlighted untraceable user activities and uncontrolled data access—fundamental flaws in a platform requiring absolute operational integrity.
