Washington, February 14 : While U.S. President Barack Obama's blackberry has been claimed to be a spy-proof device, the world's most famous hacker Kevin Mitnick says that it can still be breached.
.
He said that Obama's super-secure BlackBerry only makes cracking into it more challenging, but it can still be done.
.
"It's a long shot, but it's possible. You'd probably need to be pretty sophisticated, but there's people out there who are," Fox News quoted Mitnick as saying.
.
Mitnick served nearly five years in prison after pleading guilty to charges of wire and computer fraud for hacking into computer systems at some of the country's largest cell-phone and computer companies during the 1990s, and he presently heads Mitnick Security Consulting.
.
"If I was the attacker, I would look to Obama's close circle of friends, family and associates and try to compromise their machines at home. The objective would be to get Obama's e-mail address on the BlackBerry," Mitnick said.
.
He said that hackers might target a person with access to Obama because their networks would be much less secure than those used by the commander-in-chief.
.
Mitnick added that upon being armed with Obama's coveted e-mail address, any hacker might send an e-mail to Obama in an attempt to lure him to a Web site that had previously been breached in order to transfer "malicious code".
.
He, however, warned any potential hacker to consider the consequences before acting.
.
"The government would go after them full force," he said.
.
Obama administration officials declined to comment on the issue.
