A misconfigured data hub within the **DHS Office of Intelligence and Analysis (I&A)** exposed sensitive national security information to thousands of unauthorized users—including government workers, private-sector employees, and foreign nationals—over a **two-month period (March–May 2023)**. The breach stemmed from a **programming error**, allowing improper access to **439 I&A products**, which were accessed **1,525 times** without authorization. Among these, **518 accesses were from the private sector**, and **46 were by non-American citizens**, primarily targeting **cybersecurity intel** (39% of accessed data), including details on **foreign hacking campaigns, state-sponsored hacker groups, and domestic protest surveillance**. The exposed records included **surveillance data on American citizens**, law enforcement investigations, and **foreign disinformation operations**, raising concerns about the integrity of the **Homeland Security Information Network (HSIN)**, which DHS markets as a secure platform for critical national security sharing. While the memo confirmed some records were accessed, it **lacked an impact assessment** on affected agencies, leaving uncertainties about broader operational or intelligence compromises. The incident underscores systemic vulnerabilities in handling **classified intelligence**, with potential repercussions for **national security, diplomatic relations, and public trust** in government cybersecurity protocols.
