A North Korean ship resurfaced after several years off-grid while signaling to international tracking systems that it was sailing with a Cambodian flag, a change that, if accurate, would breach UN resolutions.

According to the NK Pro ship tracker, the DPRK-owned vessel briefly broadcast its location near China on August 15, though did not signal its location in any port facilities.

The unusual behavior and inconsistency in the ship’s Auto Identification System (AIS) broadcasts likely constitute red flags for suspicious activity, though the ship itself is not sanctioned by the U.S. or UN Security
