Russia offers 3.9m roubles for 'research to identify users of Tor'

Russia's interior ministry has offered up to 3.9m roubles (£65,000) for research on identifying the users of the anonymous browsing network Tor, raising questions of online freedom amid a broader crackdown on the Russian internet.

The interior ministry's special technology and communications group published a tender earlier this month on the government procurement website offering the sum for "research work, Tor cipher".
