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.

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...

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:

[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:

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).

I read the source code and, from what I understood, the current output

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...

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.

Dangling DNS record for bastion.certb.cdp.bethesda.net shed riot (Aug 06)
# Summary

The hostname resolved to an address within a dynamic cloud IP pool.
The address had been released and was no longer controlled by the
organisation operating the hostname.

This condition is referred to as an "afterlife" issue.

Unlike a conventional CNAME-based subdomain takeover, the DNS record
pointed directly to a reusable cloud IP address. An attacker obtaining
that address could receive traffic intended for the...

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

Hi,

Thank you for bringing this to oss-security.

On these distros, the SCTP module is not part of a typical install, but
is in the kernel-modules-extra subpackage.

Further, that subpackage includes module blacklist files with:

blacklist sctp

Although it does not hurt (well, your wasted time)

For residential, it seems most ISPs believe RFC6177
is more of an idea than a firm suggestion[0], and if you
want a /56, you need to upgrade to being what they
consider a business site, and, of course, pay more.

Good luck…

I guess, despite being against best practices, a /64 is better than nothing… especially considering “most” home users

Anyone here have a knowledgeable contact at Frontier? I’m on a residential

they’re only handing out /64s. Obviously this doesn’t allow for proper

Re: how about a well-known DOWNGRADE BGP Community? (Was: RTBH Support Across the Industry) Saku Ytti via NANOG (Aug 05)
We ran this very config in production while we still had asr9k.

It is slightly confusing as 0, 1 and 2 on CLI are not same in Tomahawk, in HW they are well ordered. But in CLI
unconfigured 0 is worst, 1 is best and 2 is middle, so can be confusing if you debug in HW level to see where packets
are going.

I am very glad this is possible on the 9k. Are you certain there are
no negative consequences moving the entire BE traffic into a fabric
priority queue (back-pressure, etc)?

The *transit* network is technically protected. But the incentive for
the *customer* network to actually announce the scavenger route is
gone.

If the transit network is injecting a scavenger route itself without
involving the customer, sure, then this makes sense for the...

Re: how about a well-known DOWNGRADE BGP Community? (Was: RTBH Support Across the Industry) Saku Ytti via NANOG (Aug 04)
Mind you, in your scenario, even without ASR9k priorities, the network
is protected.

DoS -> IngressPE -> Core1 -> Core2 -> ASR9k -> Victim

As the victim prefix has community, IngressPE sets the LE QoS bits.
Each hop egress side stops congesting the far end ingress side
Even if ASR9k congests the victim (which it shouldn't with the right
priority level), the rest of the core is protected, so the blast zone
is still just the...

Re: how about a well-known DOWNGRADE BGP Community? (Was: RTBH Support Across the Industry) Saku Ytti via NANOG (Aug 04)
I don't think this is true.

You set 'priority level 1' for NC+AF, 'priority level 2' for BE, and
leave LE unset on the ingress policy.

This sets the fabric priority, and VoQ will honor it.

Depending on what you're after, there's a number of options.

There are very simple "turnkey" solutions like UptimeRobot and StatusCake that do periodic ping/traceroute from a
single location.

I stray from host-your-own stuff for monitoring (i.e. UptimeKuma) because you either host it in your network or at a
remote location (single origin).

Single origin pings may be good enough for public status page, but you'll be...

Re: Recommendations for public-facing automated status page? Andrew Langhorn via NANOG (Aug 04)
Atlassian bought statuspage a while ago, so it’s now Atlassian Statuspage.
You can see it in the wild at

too. Openstatus and cachet are popular OSS systems, but self-hosted.

If your SMS provider supports sending messages after being triggered by

can be used with your own SMS provider.
