Guccifer, an unemployed Romanian whose real name is Marcel-Lehel Lazar, breaks into the AmericaOnline (AOL) email account of Blumenthal. Guccifer does not have typical hacking skills but instead attempts to guess passwords and answers security questions. In recent months, he broke into the accounts of famous people, or the friends and family of famous people, including those of former secretary of state Colin Powell and former US president George W. Bush.
He takes screenshots of the text of emails of Clinton and Blumenthal discussing sensitive foreign policy issues during her time as secretary of state. He also takes a screenshot of Blumenthal’s inbox showing a list of the latest emails sent from Clinton.
In the next few days, the screenshots are made public, and for the first time, Clinton’s private email address email@example.com is revealed to the world. (USA Today, 3/22/2013) (The Smoking Gun, 3/3/2015)
