"A Pentagon-wide advisory went out one week ago warning against using the
messaging app Signal, even for unclassified information.
"A vulnerability has been identified in the Signal messenger application," begins the department-wide email, dated March 18, obtained by NPR.

Google has identified Russian hacking groups who are "targeting Signal Messenger to spy on persons of interest."
