The surveillance program involves monitoring the online activity of Russian citizens and private corporations.
Russia launched its SORM project in 1995 that allowed the government to spy on citizen's phone records.
Hacking collective Anonymous on Wednesday released over 100 gigabytes of documents that it claimed showed evidence that the Kremlin is illegally monitoring citizens across Russia.
In a Twitter post, Anonymous dumped 128GB of documents that it said it acquired from the Russian internet service provider Convex.
The hacker group claimed that the company launched a project called "Green Atom" that involves installing and maintaining surveillance equipment to monitor the online activity of Russian citizens and private corporations.
The data dump contained the information of thousands of Russian citizens who were clients of Russian corporations targeted by the surveillance program, which the group claimed to be operated by Russia's Federal Security Service (FSB).
Changes to the legislation over the last decade have covered internet providers and web companies, requiring them to install SORM equipment. »
