OnePercent Group is a cybercriminal operation active since at least November 2020 that targeted US organizations using phishing with IcedID trojans, Cobalt Strike, and double-extortion, threatening a "one percent leak" of data before escalating to a full dump or sale to REvil; the FBI issued a formal flash advisory in August 2021.
