NSE submission: detect & enumerate AI infrastructure (MCP servers + LLM inference APIs) Ben Williams via dev (Jun 20)
Hi,
I've opened a PR adding three NSE scripts and two shared nselibs to detect and enumerate two classes of AI
infrastructure that nmap doesn't currently cover:

* mcp-info (discovery, safe, version) + mcp-enum (discovery, safe): MCP server detection (initialize handshake over
Streamable HTTP + legacy SSE), OAuth 2.1 protected-resource discovery (RFC 9728), and read-only tools/resources/prompts
enumeration with schema-based risk...

[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:

- looks_like_address(value) -- regex candidate detection
- 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.

[NSE] matter-identify: identify Matter smart-home devices via mDNS Balázs Zoltán (May 11)
Hi,

Attached is matter-identify.nse, a new discovery script for identifying
Matter (formerly Project CHIP) smart-home devices.

It sends DNS PTR queries to 5353/udp for the three Matter service types
defined in the Matter Core Spec section 4:

_matter._tcp.local commissioned / operational nodes
_matterc._udp.local nodes in commissioning mode
_meshcop._udp.local Thread border routers

[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:

1. Fix OpenSSL provider...

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
1.3. My debug logs show the server is dropping the connection (EOF) during
the Nmap TLS 1.2 handshake attempt:

[PATCH] Support Linux capabilities for non-root raw packet scanning Ali Norouzi via dev (Apr 14)
Hi everyone,

I just opened a PR that adds support for Linux capabilities, allowing nmap to
perform raw packet scans without sudo when the binary has `CAP_NET_RAW` set via
setcap:

Please review.

Fix for issue #3326 advait deshmukh (Apr 14)
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...

GSoC 2026: Password Security Wizard - Optimizing the NSE Brute Library Adithya Shetty (Mar 02)
Hi Nmap Development Team and Fotis,

Question about Nmap and GSoC 2026 Sweekar (Jan 29)
Hi Nmap developers,

I am a student contributor and have previously worked on Nmap. I am
preparing for Google Summer of Code 2026 and wanted to ask whether Nmap is
considering participating as a mentoring organization this year, or if
there are no plans at this time.

Thank you for your time and for maintaining such an important project.

Best regards,

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...

Nmap 7.95 released: OS and service detection signatures galore! Gordon Fyodor Lyon (May 05)
Dear Nmap Community,

I just arrived in San Francisco for the RSA conference and am delighted to
announce our Nmap Version 7.95 release! I'm most excited that we finally
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.

RE//verse, DistrictCon, an Anole Friend Dave Aitel via Dailydave (Feb 02)
Last month was DistrictCon, a great conference that I did not attend
because the sky decided to dump snow on Washington, DC. Anyone who has
spent more than ten minutes in that city knows this is how you cancel every
flight out of DCA and turn the roads into skating rinks filled with deeply
furious government contractors. Life is short, so I remained in Miami where
it was 80 degrees and everyone was pretending winter is a myth.

For reasons I still don’t fully understand, Miami Beach has enormous
colonies of turkey vultures. You’ll see them circling over the city and the
interstates, perched like huge awkward toddlers on lampposts, or standing
motionless as a shadow in the strip of grass between the road and the blue
water of the bay. If you look up at almost any moment, there’s a column of
them somewhere overhead, wings spread wide, fingers splayed, feeling the...

Re: Defense ? Dean Pierce via Dailydave (Nov 16)
I like the idea of having a software supply chain that people can pay into
that basically funds a universal bug bounty system for anything that
matters.

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...

Re: Defense ? Chris Anley via Dailydave (Nov 16)
(gingerly raises head above parapet)

Historically, “we’ve” moved the bar in defense.

- Everything is now in the cloud, accessible 24/7 via APIs whose keys are stored in plaintext alongside code, or via
preauthenticated sessions
- Everything has ~40 dependencies, each of which has ~40 dependencies, etc, which, combined with a published CVE rate
of 1 per 15 minutes (calendar year 2024), means that patching an enterprise before an...

Re: Defense ? Alfonso De Gregorio via Dailydave (Nov 16)
Imbalances in the skills and workforce are real. The gap remains hard
to bridge also in the presence of greater degrees of automation that
AI buys us, because, at this stage, we want humans to be in the loop –
and for good reasons – and, also, cause we are not going to grow the
skillset faster than the attack surface, I am afraid.

I hate to sound like a broken record, but I will take a bite
regardless: those imbalances are a byproduct of the...

Re: Defense ? Conan Dooley via Dailydave (Nov 16)
Reduce complexity, duplication, and scope in your infrastructure. Your
developers and infrastructure staff would need to agree on standardized

scope, and make them accountable for making sure adding that level of
complexity led to business value that was greater than that overhead (vs,

How would one actually move the actual bar in defense? A big part of me
thinks that you're just not going to patch your way out of the problem. But
the number of organizations that you can rely on to actually make a
difference seems pretty small? Like even converting every Linux binary to

maintain and support that code base, which I don't know that you could.

Server boxes/packing request Tom Storey via NANOG (Jun 24)
Hi all, would anyone in the Los Angeles area happen to have recently taken
a delivery of, or will be taking an imminent delivery of, Dell PowerEdge

We're looking to ship about 14 of these and need boxes and foam inserts to
pack them up.

Re: BGP user friendliness (was Re: IPv4 flag day) Saku Ytti via NANOG (Jun 23)
When measuring use, we shouldn't measure bytes moved per AFI.

Because if you care about bytes moved, you can pick some big tech that
loads their global caches over IPv6 and you might be confused to think
that traction is good.

We should be looking at SRC,DST pairs over all traffic, billion bytes
is the same as 1 byte, the internet is still sometimes used for
something else than looking at big tech ads, not much by byte count,
but by...

Tom,

a certain way, that may require more complexity that has to be paid for. (
in equipment or expertise.) Or > they can just swap cables and reboot
something once in a while, and find that acceptable.

I don't think this is a valid expectation.

The reality is they just make it work with current products, over IPv4, and
the IPv6 usage graph is stuck at 50% and doesn't really move up (at least
not fast enough).

Tnx
Arie

Re: BGP user friendliness (was Re: IPv4 flag day) Shane Ronan via NANOG (Jun 23)
But when something works with IPv4, we shouldn't expect that the user
experience is reduced when moving to IPv6.

Shane

Re: BGP user friendliness (was Re: IPv4 flag day) Tom Beecher via NANOG (Jun 23)
This is just the standard complexity vs cost question.

If someone wants 2 upstreams , that's easy. If they expect it to function a
certain way, that may require more complexity that has to be paid for. ( in
equipment or expertise.) Or they can just swap cables and reboot
something once in a while, and find that acceptable.

I'm amazed anyone in this list would consider PAT in IPv6 as a preferred solution.

If you need fast failover multihoming with consumer-class connections (ignoring the fact that connections will still
break when failover occurs), then use NPT between the two providers. Pick your primary ISPs prefix as your internal
prefix, NPT to the other one, no port translation needed. Or use ULA, whatever.

This multihoming issue could have been solved...

Re: BGP user friendliness (was Re: IPv4 flag day) Saku Ytti via NANOG (Jun 23)
I think it's entirely fair to want for A but know that B must be done.

Like of course I always wanted that IPv6 would bring some brave new
world of end-to-end Internet. But I want a lot of good things for this
world, which are naive things to want under the incentives the world
has.

And in this case, not budging on our principles which cannot be
achieved is causing tremendous harm.

level of competence, agreed.

BUT: we can't expect everyone who wants to connect to the Internet to have
that level of competence.

And for those customers who do 1:many nat, my software just won't support them. It's simple enough.

NPT/1:1 NAT is fine. PAT 1:many is not. The "NAT is cancer" statement is entirely relevant.

NPT for SMB stuff is braindead simple - click a few checkboxes. That's the 1:1 scenario that just works and doesn't
require extra code (outside of external address detection) to support unlike 1:many PAT.
