Regin Espionage Tool Active since 2008 | Symantec Connect

Symantec published research on the Regin malware family, describing a sophisticated, multi-stage, encrypted backdoor active since 2008 that has been used for stealthy surveillance of private and public organizations (including telecommunications firms). Regin's modular, compartmentalized design and encrypted components enable long-term, hard-to-detect espionage activity; Symantec notes it behaves opportunistically rather than as a destructive APT.
