The DNA database used to find the Golden State Killer is a security risk from which a nation-state could steal DNA data on a million Americans. by @antonioregalado 

Security flaws in the service, called GEDmatch, not only risk exposing people’s genetic health information but could let an adversary such as China or Russia create a powerful biometric database able to identify nearly any American from a DNA sample. 

If a foreign counterintelligence agency grabbed a million American DNA profiles, that country could use genetic genealogy to identify the true identity of American spies or diplomats, locate their relatives, or discover genetic kompromat like unacknowledged children.

Since other countries don’t have such databases for the US to steal, the risk would not be symmetric.
