New Kimsuky campaign compromised South Korean software vendors

The Record · · International · Data Breaches

A North Korean state-linked hacking group known as Kimsuky conducted a recent campaign against South Korean vendors of collaborative-work software, according to South Korean researchers. The operation is consistent with Kimsuky's pattern of targeting software supply chains to gain broader downstream access.

Why this matters: When attackers go after software vendors, they are not just after the vendor. They are after every organization that runs that software. Collaborative tools are especially dangerous targets because they sit inside networks, touch communications, and often run with elevated permissions. If Kimsuky gets into a vendor's build or update process, the compromise can spread quietly before anyone notices. The real exposure here belongs to the customers downstream, not just the companies that got hit.
