  "whatItIs": "IANA assigns 7778 to interwise, a corporate e-learning and conferencing product, with no public protocol specification. What actually shows up on scans is the sequential neighbour effect: a host already using 7777 for a game or application server takes 7778 for a second instance, a query port, or an admin channel. The registration is not a reliable identification, so read the banner and the owning process rather than the name.",
  "exposure": {
    "verdict": "careful",
    "note": "Identify it before opening it — when 7778 is the companion of a 7777 service it is frequently the query or admin side, which is the half you least want reachable."
