Pentagon treats base freezer failures as a suspected hack, Reuters reports

The Pentagon is treating a spate of freezer malfunctions that spoiled food at US military bases in late August as a suspected hack, Reuters reported on 29 October, citing four officials familiar with the matter. No cause or perpetrator has been confirmed. Reuters could not ascertain how far the investigation has progressed, or whether it has reached any conclusions about what happened or who might be responsible. Nextgov/FCW reported on 29 October, citing two people familiar with the matter, that US officials suspect Iran-linked hackers are behind the freezer failures. Nextgov said it is possible the assessments may change as investigators learn more.

What Reuters reports

The malfunctions affected at least six commissaries, the on-base stores where military personnel buy food, according to a Reuters review of the bases' Facebook posts and website updates at the time. In at least one case the freezers did not simply stop: temperatures were raised overnight. Fort Huachuca in Arizona posted on 26 August that its freezer "went into defrost mode where it heated up all the food."

Asked about the investigation, the Pentagon said a Cyber Command unit was "working in close coordination with interagency and law enforcement partners." The US Army Criminal Investigation Division said its Cyber Field Office was involved and was working with French law enforcement to better understand "the refrigeration outages in Europe." One official told Reuters that military investigators were in touch with French counterparts about a similar attack on commercial freezers in October.

The French incident

According to Reuters, that attack overrode temperature controls on commercial cooling units in more than 350 establishments in France, and some units were heated so much that they caught fire. Reuters said it could not establish whether Danfoss equipment, or any other controller brand, was in use at the US bases. Neither Danfoss nor the French Embassy in Washington replied to Reuters.

Reuters credits the blog Signal and Silence with first reporting the failures on 28 August. It credits Stars and Stripes with reporting the investigators' involvement and the Daily Telegraph with reporting their French contacts.

Why it matters

If it is confirmed as a cyberattack, the case would show that cold-storage controls can be tampered with to destroy stock, not just switched off. Until investigators say more, operators of networked refrigeration should treat this as a prompt to check what is reachable from the internet, not as evidence about any particular product.
