Dear Senator, I am writing all US Senators about the national security issue of Russia hacking our troops' smartphones. As you can read in the attached article, US Army Lt. Col. L'Heureux discovered them physically tracking to geolocate him. I was a USAF targets intelligence officer. Those lat/longs enable Russian target intel officers to put guided munitions on his position if hostilities break out. My Senator, Angus King, stated "The next Pearl Harbor will be cyber an we are already under attack!" Please stop this ongoing attack. Help get our troops the MFA/OOBA defensive software, chosen by DISA, on their mobile devices as soon as money is available following passage of the Federal funding authorization bill. Thank you for consideration of my viewpoint on this vital communications security matter. Sincerely, 4sleddogs Major USAF Retired. (This is what I am in the process of sending them. Some may question why I don't mention SFOR directly. I refer you to the USPTO site. Ram's patent wording is "MFA/OOBA for mobile device"
