  • Alert on UDP packet type 2005 response from a Grand MA 300 device on port 4370 — this response indicates the device is requiring a password and is therefore susceptible to brute-force.
  • Network sniffing of traffic to/from Grand MA 300 on UDP 4370 can also disclose the PIN directly; monitor for unauthorized passive capture sessions targeting this port.
  • ·The vulnerable firmware version is 6.60; confirm device firmware before applying detections to avoid false positives on patched devices.
