Pentagon Treating Base Freezer Failures as Suspected Cyberattack

The Pentagon is now treating a string of freezer and refrigerator failures that spoiled food at U.S. military base grocery stores in August as a suspected cyberattack, according to a Reuters report published Thursday that cited four officials familiar with the matter.

The outages hit at least six commissaries, the on-base stores where service members and their families buy groceries, according to Reuters, which reviewed the bases’ own Facebook posts and website updates from the time. Stars and Stripes reported in early September that affected stores included Fort Irwin and Travis Air Force Base in California, F.E. Warren Air Force Base in Wyoming, Fort Huachuca in Arizona, Naval Station Newport in Rhode Island, and Columbus Air Force Base in Mississippi.

In at least one case, the equipment did not simply shut off. Fort Huachuca’s Facebook account said on August 26 that its freezer “went into defrost mode where it heated up all the food,” adding, “Trust us when we say it was ‘spoiled,'” according to Reuters. The wire service reported that cooling temperatures were turned up overnight, leaving piles of melted or wilted food by morning.

Cyber Command and Army investigators involved

Asked about the probe, the Pentagon told Reuters that a unit of U.S. Cyber Command, the military’s cyber force, was “working in close coordination with interagency and law enforcement partners.” The department did not elaborate, according to the report.

The Army Criminal Investigation Division said its Cyber Field Office was involved in the investigation and was working with French law enforcement to better understand “the refrigeration outages in Europe,” Reuters reported. Stars and Stripes reported in September that Army CID and the Air Force Office of Special Investigations had confirmed active investigations at the time, while the Defense Department publicly acknowledged only a “possible refrigeration disruption.”

Reuters said it could not determine how far along the Pentagon’s investigation is or whether investigators have reached any conclusion about the cause or who might be responsible. No official finding of a hack has been announced.

A similar attack hit France this month

One of the officials told Reuters that U.S. military investigators have been in contact with French counterparts about a cyberattack on commercial freezers that disrupted supermarkets in France earlier in October. According to Reuters, that attack overrode temperature controls on cooling units at more than 350 establishments, and some units were heated so high they caught fire. Reuters reported that the French hack, like the Fort Huachuca incident, involved raising temperatures rather than simply knocking the units offline.

The Independent noted that the rash of failures and the possibility of sabotage were first reported on August 28 by a blog called Signal and Silence.

Why it matters

If investigators confirm a cyberattack, it would show how exposed everyday internet-connected equipment can be, even on military installations. Reuters described the incidents as another illustration of how vulnerable critical infrastructure such as cold storage can be to hackers. For bases that must keep running under pressure, the security of something as basic as the food supply is a readiness question.

For now, the key facts are limited: the failures happened, multiple bases reported them publicly, and the Pentagon’s cyber and criminal investigators are treating them as a possible hack. Who did it, how they got in, and whether the same actors are behind the French attack remain unanswered, according to the reporting so far.
