French supermarket hackers allegedly forced some freezers to stay in defrost mode for up to eight hours overnight on 11–12 October, a French media report has claimed, delaying alarms as temperatures surged and forcing shops to throw away food. The account, from Le Monde, emerged after cyberattacks disrupted cold storage at hundreds of outlets across the country.
Affected retailers disposed of fresh and frozen stock after temperatures rose beyond safe storage levels. French authorities opened an investigation on Monday into the attacks and reported fires. The precise way the intruders accessed the equipment has not been publicly established.
