Russian startup Pirate Pay is taking aim at the growing popularity of illegal file-sharing as it looks to cooperate with music labels and movie studios to stem the distribution of copyrighted materials on the Internet. The company’s technology launches attacks on “BitTorrent swarms,” or groups of computers hosting pirated content, making it impossible for them to share copyrighted material, TorrentFreak reports. “After creating the prototype, we realized we could more generally prevent files from being downloaded, which meant that the program had great promise in combating the spread of pirated content,” Pirate Pay CEO Andrei Klimenko said recently in an interview. Pirate Pay recently received a $100,000 investment from the Microsoft Seed fund, and it claims to have blocked nearly 45,000 attempts to download pirated copies of Russian film “Vysotsky. Thanks to God, I am Alive” in a test campaign launched earlier this year for Russia-based Walt Disney Studios Sony Pictures Releasing.
