Zeon
Zeon is a ransomware group identified in reporting as one of the successor or splinter groups that emerged after the 2022 breakup of the Russian-language Conti ransomware collective. Multiple sources in the provided content state that former Conti members rebranded under three subgroups: Zeon, Black Basta, and Quantum; other reporting also lists ZEON among groups that former Conti members later joined, formed, infiltrated, or took over. The content places Zeon activity in 2022, with Trend Micro observation cited for September 2022 and possible earlier activity as early as late January 2022. Zeon is therefore best understood here as part of the broader post-Conti ransomware ecosystem tied to Russian-language cybercrime actors. Known related groups and aliases directly mentioned in the content include Conti as its predecessor context, and peer successor groups Black Basta and Quantum; Quantum is further described as later rebranding to Royal and then BlackSuit. No additional Zeon-specific victimology, TTPs, or sub-groups are directly provided in the content beyond its association with former Conti members and its place in that rebranding/splintering timeline.
