Permanent link Tool: Chrommme

NamesChrommme
CategoryMalware
TypeBackdoor
Description(ESET) Chrommme is a backdoor we found during our adventures in the Gelsemium ecosystem. Code similarities with Gelsemium components are almost nonexistent but small indicators were found during the analysis that leads us to believe that it’s somehow related to the group. The same C&C server was found in both Gelsevirine and Chrommme, both are using two C&C servers. Chrommme was found on an organization’s machine also compromised by Gelsemium group.
