Re:New OS fingerprint: China Unicom ONT/ONU (Realtek/Boa) gbfdhenr (Liang Xiangan) (Aug 01)
Hi Nmap developers,

I'd like to submit service fingerprints for a China Unicom GPON ONT (model PT927G) that I found in my home network.
This device runs a Linux-based firmware (kernel 3.18.24) and exposes several services.

**Device Information**:
- Model: PT927G
- Vendor: China Unicom (customized)
- Hardware hint: SMB share comment mentions "Realtek", suggesting a Realtek chipset.

**Service Fingerprints**:
1. **HTTP (port...

Re:Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Aug 01)
Hi developers,

I'd like to add a service fingerprint for port 37443/tcp on the Huawei AX3 router.

This port runs SSL/TLS and requires client certificate authentication (mTLS). When connecting with a self-signed client
certificate, the server rejects it with a "unknown ca" alert, indicating that it verifies the client certificate
against a trusted CA.

**Certificate details:**

Re:Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Aug 01)
Hi Nmap developers,

Following up on my previous submissions (OS fingerprint and NSE script for the Huawei AX3), I've conducted a full port
scan and discovered two additional services that may help refine the service fingerprint database.

**1. Port 37215/tcp – UPnP**
- Service identified as: `Huawei ATP gateway upnpd`
- This seems to be already correctly matched in `nmap-service-probes`. I just wanted to confirm its presence.

**2. Port...

Following up on my previous OS fingerprint submission for the Huawei AX3 router (Message-ID:

Correction: Huawei router misidentified as Netgear switch (fingerprint included) gbfdhenr (Liang Xiangan) (Jul 31)
Hi Nmap team,

I've encountered a clear OS detection misidentification that I believe should be corrected.

**Device in question**:
- A Huawei home router (MAC OUI: 30:A9:98 -> Huawei Device)
- Open ports: 53, 80, 443 (typical router/AP, not a headless switch)
- Running: Linux-based firmware (likely 3.18.24)

**Current incorrect result**:
Nmap 7.99 reports it as: "Netgear GS108Tv3, GS110Tv3, or GS308T switch (Linux 3.18.24)"...

[PATCH] nselib/bitcoin: add address classification helpers (refs #2857, PR #3371) Melo via dev (May 25)
PR #3371 adds three functions to nselib/bitcoin.lua:

- validate_address(value) -- Base58Check, Bech32, Bech32m validation
- classify_address(value) -- high-level classification

Supports mainnet, testnet, and regtest with full unittest (38/38 pass).
No network calls, no external APIs, no real keys, no changes to existing scripts.

[PATCH 0/5] ALPN-based HTTP/2 service detection improvements Urval Kheni (Apr 14)
Hi,

This patch series introduces ALPN-based improvements to service detection
for TLS services.

It adds support for extracting the negotiated ALPN protocol and uses
"h2" as a conservative fallback signal to infer HTTP over TLS when
service detection fails.

This improves detection of HTTP/2-only services, which return binary
responses not recognized by existing probes.

The changes are structured as follows:

Bug Report: ssl-enum-ciphers fails (EOF) on CloudFront/ECDSA targets supporting TLS 1.2 Jack Seredyniecki via dev (Apr 14)
Hello nmap dev team,

I am reporting a false negative where ssl-enum-ciphers fails to detect TLS
1.2 on a CloudFront target (itwisegroup.com:443) that uses an ECDSA
certificate and Post-Quantum hybrid key exchange (X25519MLKEM768).
While sslscan and openssl confirm TLS 1.2 is active, Nmap reports only TLS

Issue link <https://github.com/nmap/nmap/issues/3326>
Pull request link <https://github.com/nmap/nmap/pull/3337>
I read the source code and, from what I understood, the current output
appears to be intentional. The ipv4 value being shown seems to refer to the
next header, i.e., the protocol of the packet encapsulated within the outer
packet, which in this case is IPv6.
Since the user has explicitly specified -6 in the command, it...

Npcap Version 1.82 Released with VLAN Tagging and More Gordon Fyodor Lyon (Apr 28)
Dear Nmap Community,

In preparation for an imminent Nmap release (hopefully this week!), we have
released Version 1.82 of our Npcap Windows packet capture and transmission
driver. It builds upon the recent 1.81 release to add support for VLAN
tagging. This allows you to select for packets directed to a certain VLAN
or just inspect the VLAN headers on any packets received. It's especially
useful for Wireshark users. You can also now send...

Dear Nmap Community,

I just arrived in San Francisco for the RSA conference and am delighted to

tackled our backlog of OS and service detection fingerprint submissions.
We're not talking about dozens or hundreds of them-we processed more than
6,500 fingerprints!

For OS detection, we added 336 signatures, bringing the new total to 6,036.
Additions include iOS 15...

RE//verse, DistrictCon, an Anole Friend Dave Aitel via Dailydave (Feb 02)
Last month was DistrictCon, a great conference that I did not attend

I like the idea of having a software supply chain that people can pay into

You can put systems in place that utilize zero knowledge exploitability
proofs to automate bounty triage, so it doesn't even need to be run by a
central trusted entity. As the bounty markets stabilize, what you're left
with is a software ecosystem where anyone can build what they need...

Imbalances in the skills and workforce are real. The gap remains hard

the number of organizations that you can rely on to actually make a

Hello Kubernetes Community,

An NTLM coercion vulnerability exists on Windows nodes when the subPath
supplied in a pod's volumeMounts is set to a symbolic link that points to
an attacker-controlled network share. When a kubelet resolves symlinks, it
does not reject a target that resolves to a UNC path. As a result, the
kubelet will transparently attempt to authenticate to the share using NTLM.

This allows an attacker to obtain the NetNTLMv2...

Re: bgpmap.net - free multi-vantage BGP looking glass Matin via NANOG (Sep 20)
That's fair for networks where an AS's prefixes mostly share the
same paths. In my experience it isn't always the case -- we run
50+ prefixes and regularly steer individual ranges (tagging to
shift a path, announcing some prefixes only to certain upstreams),
so each prefix can end up with quite a different path. That's when
a per-prefix view actually helps.

Hi Tom,

Fair point, and thanks for the pointer.

I should have mentioned this in my first email: the idea came from
bgpmap.sdv.fr (SdV, AS8839). My team used it almost daily for
troubleshooting our own network (AS49556) -- it was genuinely
useful to us. A few weeks ago it started returning 403 Forbidden,
which pushed me to build our own.

No intention to compete with anyone here -- HE's tools are great
and have been around long before us....

Re: Is Snort3 no longer being developed? Oleksii Shumeiko -X (oshumeik - SOFTSERVE INC at Cisco) via Snort-devel (Aug 21)
Hi

Thank you for the question and your interest in Snort3 project.

Snort3 status has not changed. Releases are delayed for a good reason. Hopefully, they will resume in autumn. However,
exact date is not set yet.
I will ask around if we can share more details.

Thanks,
Alexey

Is Snort3 no longer being developed? Dheeraj Gupta via Snort-devel (Aug 20)
Hi,

The official Snort3 github repo has had no new commits since almost 4
months. Last commit was on 24-Apr-2026 (Snort3 rel 3.12.2.0). Has Cisco
made any announcement regarding change in status of Snort3 project which I
may have missed?

Thanks,
Dheeraj
