Add a billionaire Silicon Valley titan to the growing list of public figures victimized by the hacker “Guccifer.”

Venture capitalist John Doerr had his AOL account breached several days ago by the same hacker responsible for illegally accessing the e-mails of Colin Powell, former White House aide Sidney Blumenthal, and assorted Bush family members (among others).

Doerr, 61, is a general partner at Kleiner Perkins Caufield & Byers, the powerhouse venture capital firm. Doerr, whose net worth Forbes pegs at $2.7 billion, has worked closely with firms like Google, Amazon, Twitter, and Groupon, and has been a member of Google’s board of directors since May 1999.

Doerr’s AOL account was broken into last week by “Guccifer,” who sent unsolicited e-mails to TSG from the compromised account. “do you like my new face?” the hacker wrote in one e-mail. “i wear glasses right now an I have 2 zillion + in my bank accounts:))” Doerr is pictured above.

During his months-long spree, “Guccifer” has employed a series of “burner” e-mail accounts, and has also sent correspondence while “inside” e-mail accounts he has breached (including those of Doerr; John Negroponte, former U.S. ambassador to the United Nations; and the wife of a Hollywood actor).

To prove that he controlled Doerr’s AOL account, “Guccifer” forwarded a screen grab of a page from its “Contacts” section that listed e-mail addresses and/or phone numbers for several Kleiner Perkins officials, as well as Doerr associates like author Walter Isaacson and AOL co-founder Steve Case. The “Guccifer” screen grab also showed that the Doerr account contained at least 5000 e-mails.

Doerr did not reply to a TSG e-mail seeking comment about “Guccifer”’s illegal access of his AOL account.

Doerr is not the first Kleiner Perkins figure to be victimized by the hacker. Powell has served as a “strategic adviser” to the firm since July 2005. After breaching the former Secretary of State’s AOL account earlier this month, “Guccifer” had access to correspondence from Kleiner Perkins partners and even confidential tax documents provided to Powell by the firm.
