Microsoft Corp., the largest software maker, said a small number of its computers were infected by malicious software in a cyberattack similar to those experienced by Facebook Inc. (FB) and Apple Inc. (AAPL)
There’s no evidence that customers were affected, Microsoft said in a blog post Friday. Some of the techniques were similar to those documented by others, and the investigation is ongoing, Microsoft said.
The incident follows recent attacks that hit more than 40 companies, including microblogging service Twitter Inc., and were linked to an Eastern European hacker gang trying to steal company secrets, Bloomberg News reported Feb. 20, citing two people familiar with the matter.
“This type of cyberattack is no surprise to Microsoft and other companies that must grapple with determined and persistent adversaries,” the company said in the blog post.
