A .S. intelligence official tells Inside the Ring that China is the main suspect in the sophisticated computer attack on the defense giant Lockheed Martin announced Sunday.

The Bethesda-based company said in a statement that its computer network was targeted May 21 with a ” significant and tenacious attack on its information systems network.”The attack was thwarted and no data was compromised, the company said.

“The fact is, in this new reality, we are a frequent target of adversaries around the world,” Sondra Barbour, Lockheed’s chief information officer, said in a letter to employees. She said one new measure was for the company to upgrade “our remote access SecurID tokens” used by employees to access the network.

The intelligence official said the link between the attack and China is based on initial analysis of the methods used. Unidentified hackers used counterfeit SecurID tokens to break through security barriers and breach the Lockheed Martin network. The tokens generate codes that, when mated to a secure computer, provide the first step in providing secure off-site access to networks.

The tokens used to gain unauthorized access to Lockheed Martin were reproduced from public key cryptology technology used by the security company RSA that was targeted in an attack originating from China several months ago, the official said.
