Google has acquired German security firm Zynamics, which was founded in 2004 by respected security expert Thomas Dullien, better known in the hacking community as "Halvar Flake."

"We're pleased to announce that Zynamics has been acquired by Google!" read a short statement provided on Zynamics' blog. "If you're an existing customer and do not receive our e-mail announcement within the next 48 hours, please contact us at All press inquiries should be sent to"

Asked for comment, a Google representative provided this statement: "We're delighted to have the Zynamics team aboard and hope their tools and skills in fighting malware will help us better protect Google's users."

Details of the deal were not disclosed.

Zynamics sells software, including BinDiff, BinNavi and VxClass, that allow companies to learn about and prevent security weaknesses and analyze malware.

Dullien often speaks at security events in the U.S. In 2007, he was scheduled to present a talk at DefCon, but was denied access at the border after U.S. Customs agents found his security research materials in his luggage and claimed he was subject to H-1B visa regulations.
