Microsoft (NASDAQ:MSFT) was hacked in connection with the attack on SolarWinds’ widely used management software.
Like with the cyberattack of SolarWinds, hackers infiltrated Microsoft products and then went after others. According to the story, it’s not immediately clear how many Microsoft users were affected.
It’s a troubling look for Microsoft, which has been beefing up its own security offerings, including in its Office 365 software suite. The stock fell about 0.7% after the report.
Microsoft has taken steps to help secure its customers in the days since SolarWinds confirmed the attack, which was first reported by Reuters on Sunday.
Several U.S. government agencies have been breached in the attack, which impacted updates to SolarWinds’ Orion software. Microsoft counts U.S. government agencies, including the Department of Defense, as Office 365 customers. A page that has been removed from SolarWinds’ website identified Microsoft as a SolarWinds customer.
One Microsoft official tweeted "Like other SolarWinds customers, we have been actively looking for indicators of this actor and can confirm that we detected malicious SolarWinds binaries in our environment, which we isolated and removed. We have not found evidence of access to production services or customer data."
MSFT dipped 63 cents to $218.79.
