Food and beverage came in second at 11%, and transportation came in a close third with only 8%. While compiling the report, Dragos found that ransomware became the "number one cause for compromises in the industrial sector." Breaking it down further, manufacturing led the list by a landslide, accounting for 65% of all ransomware attacks. "It continues to be a constant theme in our life getting called in." Attacks by sector I think there's a decrease in people reporting it to the government, but not a decrease in actual cases," Lee said. "I would disagree with some of the public commentary I've heard from various government officials and others that based on the actions of the administration, we've seen a decrease in ransomware cases.

While testifying at the Committee on Energy and Commerce of the House of Representatives last year, Lee said he believed a significant number of ransomware cases go unreported. While rarely gaining national attention on the level of Colonial Pipeline, such ransomware attacks are becoming common. One reason contributing to it gaining national attention was that Colonial "did the right thing, taking down their operations environment proactively," he said, which temporarily halted pipeline operations. Very rarely, he said, is ransomware going to be a national security event like it was with the Colonial Pipeline, for example. Lee addressed the concerns during a media preview of the 2021 report last week. While the Colonial Pipeline attack affected only IT systems, and the FBI seized back a portion of the ransom paid by the company, it represented an increasing threat to ICS and OT environments.ĭragos CEO and co-founder Robert M. Three heavily reported attacks included the Colonial Pipeline Co., JBS Foods and a water treatment facility in Oldsmar, Fla. "During 2021, cyber risk to industrial sectors grew and accelerated largely led by ransomware," the report said. Most notably, Dragos discovered a growing concern over ransomware attacks, particularly against the manufacturing sector.
