The list of significant cyberincidents in 2021 compiled by the Center for Strategic and International Studies includes 71 items through June. In addition to the Microsoft Exchange hack that penetrated 250,000 networks worldwide, there were the ransomware attacks on Colonial Pipeline, which shut down the U.S.’ largest fuel pipeline; the attack on the world’s largest meat processing facility, JBS; on Acer, the Taiwan computer manufacturer; as well as a North Korean attack on South Korea’s Atomic Energy Research Institute; and intrusions at water processing facilities in Norway, Israel, Florida and California. The list doesn’t include the July 4 hack by REvil, a suspected Russian government supported group of cybercriminals, that hit as many as 1,500 companies in what has been called the largest ransomware attack ever.
