In a blog post , Microsoft Corp. security manager Phillip Misner said that the software giant had already built defenses against nine of the 12 tools disclosed by TheShadowBrokers, a mysterious group that has repeatedly published NSA code . The three others affected old, unsupported products.
“Most of the exploits are already patched,” Misner said.
The post tamped down fears expressed by some researchers that the digital espionage toolkit made public by TheShadowBrokers took advantage of undisclosed vulnerabilities in Microsoft’s code. That would have been a potentially damaging development because such tools could swiftly be repurposed to strike across the company’s massive customer base.
