Symantec-linked reporting traces Lazarus activity from early DDoS operations against U.S. and South Korean government, financial, and media sites through destructive attacks, espionage, bank fraud, watering holes, and WannaCry. The excerpt highlights repeated South Korea targeting, including 2011 DDoS activity using embedded commands, 2013 Jokra wiping attacks against banks and broadcasters, and Castov malware used to steal passwords, account data, and digital certificates. It also connects later Lazarus-linked operations to Destover at Sony Pictures, BanSwift and Contopee code sharing in SWIFT-related bank thefts, Ratabanka watering-hole activity against banks, and tool, technique, and infrastructure overlaps with early WannaCry attacks. The chronology matters because it shows Lazarus evolving from disruptive attacks into financially motivated and globally disruptive operations while retaining recurring destructive tradecraft.
