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,
Sweekar

HTTP2 cleartext service probe Harrison Neal (Dec 24)
Good day,

In instances where HTTP2 is used cleartext without TLS+ALPN (a.k.a., h2c,
prior knowledge), nmap does not appear to have a service probe.

The following is something really simple based on RFC7540, which covers the
initial client message and the server's initial SETTINGS frame. The match
regex below ignores the length (RFC says the server's initial SETTINGS
frame can be empty, nghttpd appears to provide a single entry for...

GitHub PR #3214: Add compatibility fixes for various OSes + multiplatform autobuilds Jordan Ritter (Oct 30)
Just submitted https://github.com/nmap/nmap/pull/3214 — I think the contributing guidelines say to give an extra heads

The PR adds compilation fixes for FreeBSD, NetBSD, OpenBSD, Solaris, macOS, and Windows, against current master (on

I got the sense you guys may not have broad OS coverage in the existing TravisCI setup — given all the problems...

Re: .NET Wrapper for Npcap Daniel Miller (Oct 30)
Steve,

Npcap ought to work with any existing WinPcap wrapper, since the API is
backwards-compatible. I have not used any C# wrappers myself, though I am
aware of SharpPcap (https://github.com/dotpcap/sharppcap) as another.

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.
Additions include iOS 15...

CVE-2025-12758: Unicode Variation Selectors Bypass in 'validator' library (isLength) Karol Wrótniak (Jan 29)
Summary
=======
A vulnerability was discovered in the popular JavaScript library
'validator'.
The isLength() function incorrectly handles Unicode Variation Selectors
(U+FE0E and U+FE0F). An attacker can inject thousands of these zero-width
characters into a string, causing the library to report a much smaller
perceived length than the actual byte size. This leads to validation
bypasses,
potential database truncation, and Denial of...

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.

feeling the air Dave Aitel via Dailydave (Jan 05)
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
libraries, frameworks, etc, and you'd need skilled technical staff to
validate when people said doing something wasn't possible within that
scope, and make them accountable for making sure adding that level of
complexity led to business value that was greater than that overhead (vs,
say, just...

Defense ? Dave Aitel via Dailydave (Nov 15)
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
rust would only make sense if you could find a team that could actually
maintain and support that code base, which I don't know that you could.

Offensive AI Con Dave Aitel via Dailydave (Oct 08)
So I just got back from "Offensive AI Conference" in San Diego and it was a

All 3 of these "Heap-buffer-overflow" issues are actually out of bounds

blindly copying what it says into advisories and CVE titles.

It can't be ruled out (without code review) that if the out of bounds

I don't think I view this as a vulnerability, but I think the topic is

Re: Router Recommendations Brandon Martin via NANOG (Feb 09)
An Arista 7280SR3AK-48YC8 has the port selection you want along with FIB
scale. IDK exactly what you mean by meaningful packet buffers, but it's
not a dedicated small-buffer edge box. It should run about 300W.

The older 7280SR2K-48C6 also has the port selection and FIB scale you
want and can be found used at a price that may be more budget-friendly
but is near or just past end-of-support.

The non-K versions will do 2M with (what...

If you can't do control plane protection on a device, you should yeet it
into the sun, even on an internal network. Lateral movement is a thing.

Re: Router Recommendations Tom Beecher via NANOG (Feb 09)
Kinda want a pony here. :)

Put all your 100G ports on a device up top , you can do small buffers with
lots of RIB.

100G downlink to an agg device that consolidates all your 10/25s , has
deeper buffers to handle the speed mismatches, and needs almost nothing for
RIB.

You'll be better off.

Re: Router Recommendations Mike Hammett via NANOG (Feb 09)
I'd consider that a bad-faith argument.

"What if there is no control/management plane protection to the device?"

If any box is on the public Internet without management plane protection, you're going to be compromised. Sure, some
may be faster than others, but that doesn't excuse you from rudimentary protections.
