An anonymous reader writes: The notorious hacker most recently in the news for releasing Clinton Foundation documents has said on Thursday in a blog post that the stolen confidential files from the DNC was his "personal project." Guccifer 2.0, as he identifies himself as, added that security firms and the DNC may be trying to blame the attack on Russia, but "they can prove nothing! All I hear is blah-blah-blah, unfounded theories, and somebody's estimates," he wrote. He claims to be Romanian and says he acted alone, pouring water on the theory that he may be a "smokescreen" to divert attention away from the real culprits, that may have been expert hacking teams based in Russia. "I'd like to reveal a secret to all those cool IT-specialists: All the hackers in the world use almost the same tools," he said. "You can buy them or simply find them on the web." He broke into the network using a little-known vulnerability found in the DNC's software, he added. "The DNC used Windows on their server, so it made my work much easier," he said. "I installed my trojan-like virus on their PCs. I just modified the platform that I bought on the hacking forums for about $1.5k." Guccifer 2.0 also disputed the idea that the DNC breach was an intelligence gathering operation for Russia, saying it was hacktivism.
