Microsoft says a foreign power enlisted more than 1,000 software engineers to pull off a massive computer hack against U.S. government agencies.
An investigation by Microsoft revealed hackers were able to access Microsoft’s source code, but no changes were made, the company said in a blog post.
“We detected unusual activity with a small number of internal accounts and upon review, we discovered one account had been used to view source code in a number of source code repositories,” the blog said. “The account did not have permissions to modify any code or engineering systems and our investigation further confirmed no changes were made.”
Intelligence and law enforcement officials are still trying to piece together the cyber-espionage campaign blamed on Russia that has badly shaken the U.S. government and private sector.
