Matt Thomlinson, general manager of Trustworthy Computing Security at Microsoft, just wrote a blog post about this. Due to Microsoft protocol, the Redmond software giant didn’t make any public statements as they figured out exactly what was going on.
“During our investigation, we found a small number of computers, including some in our Mac business unit, that were infected by malicious software using techniques similar to those documented by other organizations,” Thomlinson writes.
Thomlinson noted the attacks on Facebook and Apple and the Microsoft computers were infected with malware using techniques similar to the Facebook and Apple hacks. Luckily, there is no evidence of customer data being affected.
“This type of cyberattack is no surprise to Microsoft and other companies that must grapple with determined and persistent adversaries (see our prior analysis of emerging threat trends),” he wrote. “We continually re-evaluate our security posture and deploy additional people, processes, and technologies as necessary to help prevent future unauthorized access to our networks.”
Microsoft’s investigation is ongoing.
