Manual Data Transfers Turn National‑Security Networks Into Easy Targets

A recent CYBER360 analysis highlighted that numerous national‑security agencies still depend on manual data‑transfer methods—such as USB sticks, external hard drives, and optical media—to move sensitive information between isolated systems. These physical media are frequently exchanged without rigorous sanitization or authentication, creating a predictable attack surface that threat actors exploit by pre‑infecting the devices before they reach the target environment.

The consequences are severe: compromised media can introduce malware, exfiltrate classified data, or sabotage critical infrastructure, undermining mission integrity and national defense. Defenders must prioritize eliminating ad‑hoc transfers, enforce strict media‑control policies, deploy automated encryption and integrity‑checking tools, and embed zero‑trust principles across all data flows to prevent these low‑tech, high‑impact breaches.
