Intel sues former staffer for allegedly stealing Xeon cloud secrets in USB drives and exploiting info at Microsoft

Redmond says it used forensics to find files on its own gear... rather than avail itself of deals for rivals

Intel has accused a former staffer of not only leaving the manufacturer with a trove of confidential documents but also trying to use the information they contained to help Microsoft.

In a lawsuit [PDF] filed on Friday in a federal district court in Oregon, Intel said Dr Varun Gupta spent a decade at Chipzilla before departing in January 2020. The suit alleges that Gupta had a handle on Intel’s trade secrets and strategies for selling custom Xeon chips, among other confidential data, and was not afraid to exploit that information in his new gig at Microsoft.

“Gupta explicitly referred to pricing offers and technical specifications that Intel had developed and marketed for other cloud computing environments to leverage favorable terms for Microsoft,” the suit stated. In other words, the allegation is that Gupta used details of confidential deals Intel had struck with Microsoft's cloud rivals to negotiate better contracts for the Azure goliath.

The defendant had no right to use that information. Indeed, Intel said he would have been aware he was not allowed to because his employment contract contained lots of clauses about trade secrets, and he was asked to sign a “trade secret acknowledgment form” that “specifically identifies the categories of confidential information and trade secrets to which the departing employee has had access and confirms the employee’s contractual obligation not to use or disclose that information post-employment.”

But Intel alleged that in his last days at the company, Gupta moved 3,900 internal documents from his company laptop to two external USB-based drives, one made by Seagate and another from Western Digital. The suit claimed Intel knows the drives’ serial numbers.

Four days after leaving Intel, Gupta took up a new role as a principal of strategic planning in Microsoft’s Cloud and Artificial Intelligence department. The suit alleged he immediately used info he accessed at Intel “in head-to-head negotiations with Intel concerning customized product design and pricing for significant volumes of Xeon processors.”

Intel’s suit said that its own staff who subsequently negotiated with Gupta at Microsoft became suspicious he had stolen documents from Chipzilla. The chip giant’s investigations, we're told, yielded evidence about both external drives being used to store sensitive files, and Intel asked Gupta to hand over the first one. He said he could not find it, and had never connected it to an Intel-owned PC.

By this time Intel had asked Microsoft for help. The Windows giant, we're told, discovered the first drive had been used within its walls, including on Gupta’s Microsoft-issued PC.

The suit alleged that one of the files from the disk was also found on that Microsoft PC’s hard drive. Gupta said he gave away the second drive and does not know where it might be found. It has never been recovered. And the second drive is even scarier, because it contains documents including “highly sensitive product specifications for customized Xeon processors.”

“This confidential information would be extremely useful to Gupta in his employment at Microsoft because it provided him information about Intel’s manufacturing capacity and customized product offerings for other data centre and cloud computing environments—which Gupta could then leverage in his negotiations with Intel on behalf of Microsoft,” the suit alleged.

The filing stated that Gupta claimed he accessed the Intel documents either from public portals or was provided them by Microsoft. Intel assessed that argument as “nonsensical” based on its probe into the two external drives.

If nothing else, this tells us that Microsoft and Intel both have some impressive forensic capabilities.

Intel wants Gupta to hand over the drives and any devices to which they were connected, then sign documents declaring he has no more of the company’s information in his possession.

Chipzilla also wants $75,000, which it said is the cost of getting the matter to its current state, plus costs, compensation for breach of contract, and “an award of exemplary/punitive damages.”

Intel doesn’t say what that will add up to beyond the $75k costs it claims to have incurred so far. But the filing refers to the case of Anthony Levandowski, the top engineer who pleaded guilty to stealing self-driving car trade secrets from Google. Levandowski was jailed and hit with a lawsuit seeking $179m in damages, then pardoned by Donald Trump. ®
