Microsoft is patching a major Windows 10 flaw discovered by the NSA (updated)
For a change, the NSA disclosed the vulnerability rather than exploiting it.
The IT world is waiting on pins and needles today for a high-profile Microsoft Windows 10 security patch, and now we know why. The US National Security Agency (NSA) discovered a serious flaw in Windows 10 that could expose users to surveillance or serious data breaches, according to the . That was backed by , which reported that the NSA confirmed that it did find a major vulnerability that it passed on to Microsoft.
The NSA confirmed that the vulnerability affects Windows 10 and Windows Server 2016. It said that it flagged the dangerous bug because it "makes trust vulnerable." However, it wouldn't say when it found the flaw and declined to discuss it further until Microsoft released a patch.
According to Krebs, the vulnerability was found in a Windows component called crypt32.dll, which handles "certificate and cryptographic messaging functions," according to Microsoft. An exploit in that area could affect authentication on Windows desktops and servers, sensitive data on Microsoft's Internet Explorer and Edge browsers and many third-party applications. Hackers could also use it to spoof digital signatures, making malware look like a legitimate app.
