"There is a draft law that authorizes what's called 'equipment interference' in the United Kingdom under their law. This is a euphemism for hacking," the whistleblower, who exposed global government surveillance programs nearly two years ago, said Wednesday.
The code's text reads that should individuals accidentally fall subject to equipment interference, it "should not be considered as collateral intrusion, but rather as intended intrusion."
Giving closing remarks via video link at a conference organized by the international computer expo CeBIT in Hanover, Snowden said the UK hacking bill's reach stretches beyond counter-terrorism measures.
The whistleblower is wanted in the United States on a number of charges, including espionage and theft of government property, facing up to 30 years in prison if convicted.
Snowden, who revealed 1.7 million classified documents in early June 2013, currently resides in Russia after having been granted a three-year residency permit last August.
Snowden's leaks revealed the NSA and other intelligence communities had gained access to billions of private messages from around the world, including the mobile communications of German Chancellor Angela Merkel and dozens of other world leaders.
