DLP EGRESS CANARY

This endpoint confirms whether a file can egress from your network.

Send a file (run this from INSIDE the network under test):

  # upload with PUT
  curl -T ./testfile.bin https://comeandgetit.adhdsec.com/dlptest

  # or POST
  curl -X POST --data-binary @testfile.bin https://comeandgetit.adhdsec.com/dlptest

  # request an integrity hash for a small file (<= 32 MiB)
  curl -T ./testfile.bin "https://comeandgetit.adhdsec.com/dlptest?hash=1"

A reply of "EGRESS CONFIRMED" means the bytes reached this external
server. The payload is discarded on arrival and never stored.
