Marcel Lazăr Lehel (born in ), known as Guccifer, is a Romanian hacker responsible for a number of high-level computer security breaches in the U.S. and Romania. Lehel targeted celebrities, Romanian and U.S. government officials, and other prominent persons.
Lehel first appeared in news media in February 2013 after the website The Smoking Gun reported he was responsible for hacking the AOL account of Dorothy Bush Koch, sister of former president George W. Bush. Family photos of former president George H. W. Bush, who was in the hospital at the time, were circulated to the internet. He also circulated a self-portrait painted by George W. Bush. Lehel went on to hack a number of AOL, Yahoo, Flickr, and Facebook accounts, giving him access to information about current and former high-level government officials.
In January 2014, Lehel was jailed in his native Romania for seven years after being convicted of hacking emails of Romanian officials. Lehel was subsequently extradited by Romania to the United States, where he was indicted on federal charges. In May 2016, Lehel pleaded guilty in federal court to two charges. He is currently awaiting sentencing at Alexandria City Jail in Alexandria, Virginia.
