美国调查人员正与法国警方合作，调查欧洲发生的冰箱故障，此前美军基地也出现了原因不明的类似故障。
American investigators are working with French police on refrigerator outages in Europe amid unexplained failures at US military bases.
此次合作源于本月初法国超市疑似遭遇破坏活动，黑客据称将冰箱和冷柜温度升至 50 摄氏度（122 华氏度）。
The collaboration follows suspected sabotage at French supermarkets earlier this month, when hackers allegedly raised fridge and freezer temperatures to 50C (122F).
约 700 家超市遭袭，数千吨食物变质，极端高温在某些情况下引发火灾并触发喷淋系统，造成进一步损失。
About 700 supermarkets were targeted, spoiling thousands of tons of food, with extreme heat triggering fires and sprinkler systems in some cases, causing further damage.
目前尚未确定肇事者，但调查人员认为黑客利用了联网制冷控制系统的漏洞。
No perpetrator has been identified, but investigators believe the hackers exploited a weakness in the internet-connected refrigeration controls.
弗吉尼亚联邦大学国土安全与应急准备副教授克里斯托弗·怀特表示，美军基地的故障与法国超市遭受的攻击相似。
Christopher Whyte, an associate professor of homeland security and emergency preparedness at Virginia Commonwealth University, said the American failures resembled the attacks on French supermarkets.
“它们地理位置分散，显然都是冰箱故障，且都在相当短的时间内发生，”他对《每日电讯报》表示。但他称美军基地故障的原因仍不清楚。
“They’re geographically dispersed. They’re obviously all refrigerator failures and they all happen in a pretty short amount of time,” he told The Telegraph. But he said the cause of the US outages remained unclear.
美国陆军刑事调查部（CID）发言人称，该部门“正积极与国防军需品署和国防刑事调查局（DCIS）合作，以确定军需品商店制冷设备故障的全部情况”。
A spokesman for the US army’s Criminal Investigation Division (CID) said it was “actively working with the Defence Commissary Agency and the Defence Criminal Investigative Service (DCIS) to determine the full extent of what occurred with the refrigeration units in the commissaries”.
“陆军刑事调查部还在与国防刑事调查局和法国执法部门合作，了解欧洲发生的制冷故障。”
“Army CID is also working with DCIS and French law enforcement in understanding the refrigeration outages in Europe.”
