[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...

Hello Everyone!

We are conducting a research study on how organizations handle the
aftermath of cybersecurity incidents and we would greatly value your
perspective. Our focus is on what happens after a security incident is
resolved. How do teams reflect on these events? How do organizations

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

My name is Adithya, and I am a 4th-semester Computer Science student
specializing in Cybersecurity. I am writing to express my strong interest
in the "Password Security Wizard" project for GSoC 2026.

Over the past few days, I have cloned the repository, set up my build
environment, and have been digging into the nselib/brute.lua library and
several of the -brute.nse scripts (specifically focusing on...

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

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

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
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,

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.

I'd like to also point out that the copy.fail website may underplay the
impact this mitigation has on userspace. It's not the easiest thing in
the world to find out everywhere where an AF_ALG socket is opened and
then set up in AEAD mode in Debian, but so far I've found that at least
bluez, cryptsetup, iwd, and stress-ng contain code that does this, as

An initial test of adding:

initcall_blacklist=algif_aead_init

to the kernel command line and rebooting seems to block the exploit.

Cheers.

So this is one of the worst make-me-root vulnerabilities in the kernel
in recent times. I see that on the 11th of April 6.19.12 & 6.18.22 were
released with the fix backported.

Longterm 6.12, 6.6, 6.1, 5.15, 5.10 have not received the fix and I
don't see anything in the upstream stable queues yet as I write. My
guess is backporting that far back is not as straightforward. As this
was introduced in 2017 all those older kernels are...

You think you can type into an llm build a better protocol and it will snap
one out of the air.

But do you think you should build an ietf standard in 2026 with out llm.

If your not using llm everyday your competitors are.

But further to my problem what else do i need to solve.

I solved route growth as peering is now optional,
Vpns by making vpn over quic
And best path by cost factor.

Anything else need to be fixed?

Re: IPv8 / BGP8 / CF Jamie Thain via NANOG (Apr 30)
Shrihari,

The point I'm trying to work thru right now is the fib has a field to mark
forwarding for v4vpn type ii and if for the asn i make a vrf = asn and an
rd of asn:65535 i might be able to avoid tunneling and use the silicon
while in transition.

Ipv8 is not a 64 bit address its an 32bit asn postal code.

And a 32 ipv4 address.

Reinventing IP is a common enough phenomenon. None of the reinventions
have added anything new to the baseline wireline protocol that hasn't
already been discussed to death by protocol wonks, and probably
discussed to death in the early 1990s. This iteration is no different.

Appreciate attempt to solve the problem, but I am absolutely disgusted

Call me radical but I think that's an even worse problem than the LLM

completely undeserved access to capital and are burning literally

So? Fine. We're not even at the "reviewing code" stage. How about just

If anything, the existence of LLMs and VMs and software-defined light

Re: IPv8 / BGP8 / CF Saku Ytti via NANOG (Apr 30)
LLM produces code much much faster than you can review it.

This argument worked in days of yore, when the person writing the code
had to put in orders of magnitude more work in that person reviewing
it.

Anyone maintaining any open source project has seen this, massive
complicated pull requests from people who cannot code and have strong
expectations that you review it. They spent minutes generating it,
you'll spend days reviewing it.

Re: IPv8 / BGP8 / CF Mikael Abrahamsson via NANOG (Apr 30)
Agreed. This has already been making the rounds in IETF and the feedback
there was tougher because people have already lived through this with
IPv10 which wasted an enormous amount of time and effort.

Just tell whoever is proposing something like this to start coding up
their effort, and show that it works. This doesn't need more design
documents, it needs running code. Then the authors will find all the

Re: IPv8 / BGP8 / CF Jamie Thain via NANOG (Apr 29)
Shrihari

Let's think about it for a while. There are two ways to transport things in
an ipv8 network.

1. Inside the asn and it's basically ipv4 with a path set so it takes a
lookup to the next ipv4 hop but at the ipv8 router inside the asn it makes
a decision on the ipv4 address destination part and sends it to that
encapsulated address.

So basically the loopback of that ipv8 address.

2. Outside the asn it send it to the ipv4...
