Using a VPN May Subject You to NSA Spying

In a letter sent Thursday to Director of National Intelligence Tulsi Gabbard , the lawmakers say that because VPNs obscure a user's true location, and because intelligence agencies presume that communications of unknown origin are foreign, Americans may be inadvertently waiving the privacy protections they're entitled to under the law.
Several federal agencies, including the FBI, the National Security Agency, and the Federal Trade Commission, have recommended that consumers use VPNs to protect their privacy .
But following that advice may inadvertently cost Americans the very protections they're seeking.
The letter was signed by members of the Democratic Party’s progressive flank: Senators Ron Wyden, Elizabeth Warren, Edward Markey, and Alex Padilla, along with Representatives Pramila Jayapal and Sara Jacobs.
The concern centers on how intelligence agencies treat internet traffic routed through commercial VPN servers, which may be located anywhere in the world.
Millions of Americans use these services routinely, whether to access region-restricted content like overseas sports broadcasts or to protect their privacy on public Wi-Fi networks.
Because VPN servers commingle traffic from users in many countries, a single server—even one located in the United States—may carry communications from foreigners, potentially making it a target for surveillance under authorities that allow the government to secretly compel service from US service providers .
Under a controversial warrantless surveillance program, the US government intercepts vast quantities of electronic communications belonging to people overseas.
The program also sweeps in enormous volumes of private messages belonging to Americans, which the FBI may search without a warrant, even though it is authorized to target only foreigners abroad.
The program, authorized under Section 702 of the Foreign Intelligence Surveillance Act, is set to expire next month and has become the subject of a fierce battle in Congress over whether it should be renewed without significant reforms to protect Americans' privacy.
Thursday’s letter points to declassified intelligence community guidelines that establish a default presumption at the heart of the lawmakers' concern: Under the NSA's targeting procedures , a person whose location is unknown is presumed to be a non-US person unless there is specific information to the contrary.
Department of Defense procedures governing signals intelligence activities contain the same presumption.
Commercial VPN services work by routing a user's internet traffic through servers operated by the VPN company, which may be located anywhere in the world.
A single server may carry traffic from thousands of users simultaneously, all of it appearing to originate from the same IP address.
