github nmap/npcap v0.99-r5
Npcap 0.99-r5

Executable installer and debug symbols available at https://nmap.org/npcap/#download

  • Restored installer code to silently uninstall WinPcap if silent installation
    in WinPcap API-compatible mode is needed (Npcap OEM only).

  • Removed several optional passthrough driver functions that can be handled
    more efficiently by NDIS, since Npcap was not using them.

  • Added validation of IRP parameters for additional security.

  • Fixed a crash reported via Microsoft crash telemetry,
    DRIVER_IRQL_NOT_LESS_OR_EQUAL in NPF_SendCompleteExForEachOpen when the
    system is suspended. Fixes #1193.

  • Fixed a crash reported via Microsoft crash telemetry,
    DRIVER_IRQL_NOT_LESS_OR_EQUAL in NPF_IOControl when setting
    OID_GEN_CURRENT_LOOKAHEAD. Fixes #1194.

  • Bundle and install the correct public code signing certificate. The
    certificate used to sign Npcap was updated for Npcap 0.99-r4, but the public
    cert file included was not, leading to some unwanted publisher trust dialogs
    during installation.
