Utilities and infrastructure, government agencies, hospitals and healthcare institutions, schools, food production and distribution industries–even ferry service to Martha’s Vineyard, all have been attacked by cybercriminals using ransomware, probably now the most used kind of exploit of network systems.
“Even as we speak there are thousands of attacks on all aspects of the energy sector and the private sector generally…it’s happening all the time,” said Energy Secretary Jennifer Granholm to CNN.
In the first 6 months of 2022, thirty-four percent of all cyber insurance claims were due to ransomware, with an average ransom paid out by the insurance company (during the same period) was $255,000. In 2021, ransomware payments stood at $102.3 million a month—an increase of 518% from 2020. Typically, a single victim (usually a business) is hit for $50 million, up from $30 million in 2020. Sixty-eight different ransomware variants are known at present, the most notable being REvil, Sodinokibi, Darkside, Avaddon, and Phobos. The attack vector most used is business email compromise (BEC), arising from phishing emails that contain links or files that load ransomware. It has risen 97.25% since 2016.
