#Counterintelligence

After leaving counterintelligence, life became public due to WikiLeaks. This led to writing "Reverse Deception," a book on counter-exploitation, teaching how to hack hackers. It also laid out the first structured criteria for APTs. #Cybersecurity #Counterintelligence #Hacking

THE HUNT FOR SPIES IN THE US — Chinese authorities say there is “no such thing as an overseas police station.” But for those tracking foreign #intelligence operations inside the US, what the National #Counterintelligence and #Security Center (@NCSCgov) sees is quite different...

The #FBI Ten #MostWanted Fugitives Program launched in 1950 to bring national attention to dangerous criminals who have avoided capture. To date, 519 fugitives have appeared on the list. #FBI110 #FugitiveFriday

Researchers, beware of impostors trying to get information out of you with false pretexts (fake journalists, researchers, etc.). Here is most likely some Iranian dude working me... Next time, try something better than that, "kevin" #osint #cyber #counterintelligence

A Russian GRU spy posed as a Brazilian, studied in Washington and tried infiltrating an international court. That's how deep Moscow's espionage goes! Fake identities can open doors to sensitive American institutions. #GRU #Counterintelligence #NationalSecurity
