Pentagon officials on Tuesday confirmed that the temperature controls in six Army commissaries went into defrost mode overnight on 24‑26 August, spoiling thousands of meals.
The first public hint of sabotage came from the Signal & Silence blog on Aug. 28, citing social‑media posts and base website updates that described the sudden heating of frozen goods.
US Cyber Command is coordinating with federal law‑enforcement and French investigators, who are probing a similar incident that disrupted more than 350 supermarkets across France earlier this month.
Experts say the vulnerability stems from obsolete refrigeration controllers—many of which use outdated firmware—making remote manipulation easier, according to Danfoss, a Danish manufacturer that supplied some of the units.
The investigation remains in progress; the Pentagon will release further details after the cyber‑field office completes its forensic analysis, and a potential criminal case could follow if an attacker is identified.
