FBI warns of fresh North Korean hacking tactic
The US Federal Bureau of Investigation (FBI) has issued a joint advisory warning of a new tactic being used by North Korean intelligence-gathering cyber group Kimsuky. The warning is squarely aimed at think tanks, academic institutions, non-profit organizations, and members of the media in Western countries. Despite North Korea’s previous reliance on revenue from international crime to finance its weapons and military programs, the FBI reports that Kimsuky’s role is intelligence gathering. Kimsuky exploits an improperly configured Domain Name System (DNS) to mimic legitimate email senders and hack targeted individuals. Without properly configured DNS Domain-based Message Authentication, Reporting, and Conformance (DMARC) policies, malicious hackers can send spoofed emails as if they came from a legitimate domain’s email exchange.
