Many current and former members of Congress likely aren't pleased with Guccifer 2.0 after the hacker dumped their contact information online before the start of the weekend.
The deed earned the self-described lone wolf hacker, who released thousands of documents from the Democratic National Committee, a temporary ban on Twitter. He was reinstated on Sunday.
A Twitter representative declined to comment on the status of personal accounts.
Guccifer 2.0 has kept his identity a secret, but he hasn't been shy in sharing a little about himself and his motives as he continues to evade authorities. Cyber security experts have even suggested he may simply be a front for Russian intelligence. Here's what he's shared so far.
Who Is He?
Guccifer 2.0 says he's male. "I’ve never met a female hacker of the highest level. Girls, don’t get offended, I love you," he wrote in a June 30 post on his WordPress site.
Where's He From?
He has claimed he is Romanian. However, some reports questioned whether he is a native speaker. An analysis of a chat transcript by several Romanian speakers concluded Guccifer 2.0 wrote short Romanian responses with an unusual sentence structure, according to Motherboard.
Is He a Lone Wolf Hacker?
Guccifer 2.0 insists he has been acting alone. Several cyber security experts and U.S. government officials beg to differ, saying that Guccifer 2.0 is a group of hackers based in Russia and who are intent on manipulating the U.S. presidential election. When U.S. cyber experts analyzed the DNC hacks, they found digital fingerprints and techniques consistent with state-sponsored Russian hackers.
Guccifer has denied this, writing on his blog, "I don’t want to disappoint anyone, but none of the candidates has my sympathies. Each of them has skeletons in the closet and I think people have a right to know the truth about the politicians."
What's His Connection to the Other Guccifer?
The original Guccifer, former taxi driver Marcel Lazar, is the Romanian hacker who first discovered that Hillary Clinton, then secretary of state, had been using a private email server.
"He inspired me and showed me the way. He proved that even the powers that be have weak points," Guccifer 2.0 wrote.
Lazar pleaded guilty to in May to charges of identity theft and unauthorized access to protected computers before a federal judge in Alexandria, Virginia. He is now awaiting sentencing.
How Easy Is It to Break in to the DNC Sites?
The simple answer: It's not easy.
"Personally, I think that I’m among the best hackers in the world. And I don’t really think it could be easy to become a hacker of such a level," Guccifer 2.0 wrote.
The hacker said he used a zero-day exploit to get in the back door. He said he then downloaded a Trojan-like virus on their PCs.
Does He Expect to Be Caught?
Guccifer 2.0 is taking precautions in the event he is captured and prosecuted.
"I’ve expected it and that’s why I’m ready. They certainly have great possibilities. But it won’t be that easy to catch me," he wrote. "I took all precautions. Yes, there’s still a risk. But I hope [the FBI] won’t find me."
What's With the Name?
Pronounced GOO-chi-fer, the original hacker said he said combined "the style of Gucci and the light of Lucifer."
