Security experts expect many more companies to disclose that they’ve been hacked by Russian intelligence agents who stole emails from executives following disclosures by Microsoft and Hewlett-Packard Enterprise in the past week.

Microsoft said late Thursday that it had found more victims and was in the process of notifying them. A spokesperson declined to say how many. But three experts in and out of government said that the attack was deeper and broader than the disclosures to date reveal.
