North Korean Regime-Backed Programmer Charged With Conspiracy to Conduct Multiple Cyber Attacks and Intrusions -
North Korean Hacking Team Responsible for Global WannaCry 2.0 Ransomware, Destructive Cyberattack on Sony Pictures, Central Bank Cybertheft in Bangladesh, and Other Malicious Activities ... The charges were announced by Attorney General Jeff Sessions, FBI Director Christopher A. Wray, Assistant Attorney General for National Security John C. Demers, First Assistant United States Attorney for the Central District of California Tracy Wilkison and Assistant Director in Charge Paul D. Delacourt of the FBIs Los Angeles Field Office.
