By Joseph Menn SAN FRANCISCO (Reuters) – Researchers have found a flaw that could expose the identities of people using a privacy-oriented operating system touted by Edward Snowden, just two days after widely used anonymity service Tor acknowledged a similar problem. The most recent finding concerns a complex, heavily encrypted networking program called the Invisible Internet Project, or I2P. Though a core purpose of I2P is to obscure the Internet Protocol addresses of its roughly 30,000 users, anyone who visits a booby-trapped website could have their true address revealed, making it likely that their name could be exposed as well, according to researchers at Exodus Intelligence. “People shouldn’t trust something wholeheartedly just because Snowden says,” Exodus Vice President Aaron Portnoy told Reuters.
