Microsoft urgently needs to add QR code detection into EXOP. The QR codes bypass essentially all existing protections. KQL queries like the one in this thread are no longer effective, as they rely on specific filename patterns and attackers have already adapted. EXOP should be able to detect QR codes and handle the URLs just like it handles any other links. There should also be an option to block all QR codes. Or perhaps replace QR code images with a SafeLinks HTML link.
This threat is not going away, and the current tools are not able to adequately mitigate it.
