The vendor revealed the attack in a filing to the Securities and Exchange Commission but it stressed that it is often the target of malicious attempts to gain access to information and company systems.
"We regularly face attempts by others to gain unauthorized access through the Internet to our information technology systems by, for example, masquerading as authorized users or surreptitious introduction of software," stated the vendor in its SEC Form-10k Annual report.
"These attempts, which might be the result of industrial or other espionage, or actions by hackers seeking to harm the company, its products, or end users, are sometimes successful," it added.
"One recent and sophisticated incident occurred in January 2010 around the same time as the recently publicized security incident reported by Google," the filing stated.
The word "sophisticated" will have echoes of the Google attack whichwas described by the CEO of McAfee to MicroScope as one of the mostsophisticated his company had ever seen using various attack vectors totry and get through the search giant's defences.
The latest admission by In tel will raise concerns, which areincreasingly being voiced in vendor reports about the state of thesecurity market, that government backed commercial hacking is nowbecoming a source of real danger for companies.
Intel has move to play the incident down in comments made to Reuters but the sense of growing unease that started with the Google attacks, which is still being discussed as the hunt for those responsible continues.
