israeli intelligence officials monitoring Russian government hackers found they were using Kaspersky Lab antivirus software that is also used by 400 million people globally, including U.S. government agencies,  media reports said Tuesday.

The Israeli officials who hacked into Kaspersky’s network over two years ago had, at the time, warned their U.S. counterparts of the Russian intrusion, The New York Times reported.

That led to a decision in Washington only last month to order Kaspersky software removed from all government computers.

The Washington Post reported Tuesday that Israeli officials also found in Kaspersky’s network hacking tools that could only have come from the U.S. National Security Agency.

Upon this discovery, the consequent NSA investigation found that these tools had been obtained by the Russian government, the report said.

Late last month, the U.S. National Intelligence Council completed a classified report that it shared with NATO allies concluding that Russia’s FSB intelligence service had “probable access” to Kaspersky customer databases and source code.

That access, the council concluded, could help enable cyberattacks against U.S. government, commercial and industrial control networks, The Washington Post reported.

The New York Times said the Russian operation, according to multiple people briefed on the matter, is known to have stolen classified documents from an NSA employee who had improperly stored them on his home computer, which had Kaspersky antivirus software installed on it.

It is not yet publicly known what other U.S. secrets the Russian hackers may have discovered by turning the Kaspersky software into a sort of Google search for sensitive information, the report said.

The newspaper said the NSA and the White House declined to comment, as did the Israeli Embassy in Washington, while the Russian Embassy did not respond to requests for comment.

The Russian embassy in Washington last month called the ban on Kaspersky Lab software “regrettable” and said it delayed the prospects of restoring bilateral ties.

Kaspersky Lab denied any knowledge of, or involvement in, the Russian hacking. “Kaspersky Lab has never helped, nor will help, any government in the world with its cyberespionage efforts,” the company said in a statement on Tuesday.

Eugene Kaspersky, the company’s co-founder and CEO, has repeatedly denied charges his company conducts espionage on behalf of the Russian government.

Kaspersky spokeswoman Sarah Kitsos said that “as a private company, Kaspersky Lab does not have inappropriate ties to any government, including Russia, and the only conclusion seems to be that Kaspersky Lab is caught in the middle of a geopolitical fight.” She said the company “does not possess any knowledge” of Israel’s hack, the Post said.

U.S. intelligence agencies have concluded that Russian President Vladimir Putin ordered a multi-pronged digital influence operation last year in an attempt to help Donald Trump win the White House, a charge Moscow denies.
