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)

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

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

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: 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...

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

preauthenticated sessions
- Everything has ~40 dependencies, each of which has ~40 dependencies, etc, which, combined with a published CVE rate

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.

How would one actually move the actual bar in defense? A big part of me

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.

Re: Best practices for signature verifcation Clemens Lang (Jan 01)
Hi Simon,

SLH-DSA relies on the security of hashes, which I think we understand pretty well, so I’m not sure we need a hybrid
with SLH-DSA. But then again, an Ed25519 pub key and signature are minuscule compared to SLH-DSA, so maybe that doesn’t
matter.

Note that there are some outside requirements that at least companies will not be able to ignore:

Unless the CMSAlgorithmProtection attribute is added (RFC8933), it's

This looks... slightly worrying to me. Is it called "signify" or
signify-rs"?

I assume the latter is a workaround for the fact that there's already a
semi-popular "clean rust" implementation that started life in 2016,
which owns the former name:

https://crates.io/crates/signify

Re: What do you consider acceptable packet / session modification for a network operator? Lukas Tribus via NANOG (Dec 30)
In some cases the last router before the MTU bottleneck is not
emitting the ICMP Type 3 Code 4 response.
In Cisco land for example many configs and templates contain the "no
ip unreachables" interface configuration, stopping the router from
emitting all ICMP Type 3 messages, including Code 4 Frag needed.

Non routable source IPs discarded by uRPF have been mentioned, which
is a common problem.

Then there is the issue of rate limiting....

Re: What do you consider acceptable packet / session modification for a network operator? William Herrin via NANOG (Dec 30)
Actually, they only have to agree on the MRU and the upper level
protocols just about always provide mechanisms to assure the packets
they emit won't exceed the recipient's MRU. It's not -quite- that
simple but it's simple enough that but for PMTUD being broken on the
Internet we could have moved to 9k MTUs by now.

Interestingly, AWS VPCs mostly have moved to 9k MTUs. Check your EC2 instance:

$ ifconfig -a
ens5:...

Re: What do you consider acceptable packet / session modification for a network operator? nanog--- via NANOG (Dec 30)
I thought 9000-byte MTU wasn't used on LANs due to the headache of ensuring every single device on the LAN has the same
MTU.

You don't need PMTUD to work on the internet to use longer packets in your LAN. The "packet too big" reply only has to
make it from *your* edge router back to *your* server through *your* network.

But every host and switch in an Ethernet must agree on MTU because there's no Ethernet-layer PMTUD.

Re: What do you consider acceptable packet / session modification for a network operator? William Herrin via NANOG (Dec 27)
Correct: PMTUD on the Internet is broken. ISPs work around this by
engineering a clean 1500 byte path everywhere they can and clamping
the MSS the few places that they can't.

There's a reason we haven't moved up to 9kb ethernet frames on the
server and eyeball LANs. This is that reason.

Everybody emits them. Too many don't make it to the destination.

Bill Herrin

Re: What do you consider acceptable packet / session modification for a network operator? Saku Ytti via NANOG (Dec 27)
While it would be terrific if this would work, reality is that content
networks all have tried, and all have resorted to fixing lower MSS.
Internet is just too broken. Idealistically I agree.

Quic, being modern, has many of these ideas built-in.

For example, it has a spin bit and active pmtu discovery along with general
lower mss built in.

Yup, sure it’s UDP; I was just curious wether those providers were also trying to find a way to affect QUIC…

Re: What do you consider acceptable packet / session modification for a network operator? Marco Moock via NANOG (Dec 26)
It uses UDP, so it is affected by NAT, but not by MSS-clamping.
If PMTUD fails and people use MSS-Clamping, QUIC will fail.

Re: What do you consider acceptable packet / session modification for a network operator? Pedro Prado via NANOG (Dec 26)
Is QUIC also affected in any way?

I think the general stance, at least in my opinion, is that it may be acceptable for a non-fixed broadband service
(e.g., cell phone service), while it is not for a fixed broadband (FTTP or otherwise). I fully expect CGNAT, a basic
level of packet mangling in an effort to maximize performance on the cell network, etc., while I am hopping between

Some devices you can configure this, but it varies and gets even more interesting when you have a device that may not
even have an IPv4 address but is processing IPv4 packets.

Eg:

If that fixes the problem, PMTU discovery (mandatory for IPv6 and IPv4

The ISPs I used emit ICMP packet too big messages.
