When Microsoft's own engineers started using the endpoint in 2022 for its email system products, they didn't realize these checks weren't in place, either, we're told. Crucially, Microsoft did not provide enough automatic checks in those libraries to ensure that, say, an enterprise user wouldn't be validated using a consumer key, another issue it said has now been corrected. Wait, a consumer key signed tokens for enterprise email?īack to the consumer key being used to access enterprise email: Microsoft explained this dates back to September 2018, when it began offering a converged API endpoint that applications could use to authenticate users, whether those users were within an enterprise or individual consumers.Īt the time, Redmond updated its documentation and software libraries so that application developers could use this endpoint to ultimately provide a single-sign-on interface. "Due to log retention policies, we don't have logs with specific evidence of this exfiltration by this actor, but this was the most probable mechanism by which the actor acquired the key," according to Redmond. However, as per Microsoft's "standard debugging process," workers moved the crash dump from the isolated production network into a debugging environment on the internet-connected corporate network.Įven after the move, credential scanning systems did not detect the key (Redmond also says "this issue has been corrected") and while the key was sitting in the crash dump on the general IT network, Storm-0558 compromised a Microsoft engineer's corporate account and swiped the digital key from the snapshot. You do not need to be connected to the Internet to use the Office apps, such as Word, Excel, and PowerPoint, because the apps are fully installed on your computer.If the dump had stayed within the production network, it wouldn't have necessarily been the end of the world: if an intruder could access the dump in prod, they could perhaps access a lot of other things anyway.
