During an assumed breach ops via a virtual desktop interface, we discovered a wildcard allow firewall rule for the Azure Blob Storage service. We proved that even with restrictions in place, it was still possible to reach the Internet. Afterwards, we thought of abusing this firewall misconfiguration (recommended by Microsoft) in a much more useful way. To demonstrate that I built a SOCKS5 proxy that uses blobs to tunnel traffic to the target's internal network.
