Islamic State using leaked Snowden info to evade U.S. intelligence

Washington Times:

Retired Air Force Gen. Michael Hayden ran the NSA when al Qaeda struck on Sept. 11, 2001. He moved to modernize technology and methodology in an agency that some internal critics said “had gone deaf” in the 1990s.

 

“The changed communications practices and patterns of terrorist groups following the Snowden revelations have impacted our ability to track and monitor these groups,” said Mr. Hayden, who writes a bimonthly column for The Times.

 

Matthew G. Olsen, who directs the National Counterterrorism Center, supports Mr. Hayden’s assessment.

 

“Following the disclosure of the stolen NSA documents, terrorists are changing how they communicate to avoid surveillance. They are moving to more secure communications platforms, using encryption and avoiding electronic communications altogether,” Mr. Olsen, a former NSA general counsel, said Wednesday at the Brookings Institution. “This is a problem for us in many areas where we have limited human collection and depend on intercepted communications to identify and disrupt plots.”
