Israel tipped off the United States about a Russian hacking operation to obtain classified information from the National Security Agency, The New York Times reported Tuesday.

The Russians were able to hack into the home computer of an NSA employee by using an antivirus software made by Kaspersky Lab, a global cybersecurity company with over 400 million users worldwide.

According to The Times, Israeli intelligence officials who had hacked into Kaspersky’s network alerted the US about the Russian hacking, prompting the US government to order the immediate removal of any Kaspersky software from government computers.

In mid-2015, Kaspersky detected an intrusion in its network and revealed it in a public report, but did not name Israel as the intruder.

During the course of their hack, Russian officials reportedly managed to uncover hotels and conference venues used for meetings by members of the UN Security Council to discuss the terms of the nuclear deal with Iran.
