And, later alone four days, they saw the first attempts made by threat actors to access the table of contents of the exposed source cypher folder.

Even though this could point to attackers already knowing of theNotLegit flaw and trying to find exposed Azure App Service apps' source code, these scans could also be explained as normal scans for exposed .git folders.

The Redmond-based technical school giant mitigated the flaw by updating PHP images to disallow serving the .so-and-so folder atomic number 3 static calm.

The Azure App Service documentation was also updated with a new section on properly securing apps' source code and in-place deployments.
