Any hacker will tell you that the latest news and exploits are not found on any web site—not even Insecure.Org. No, the cutting edge in security research is and will continue to be the full disclosure mailing lists such as Bugtraq. Here we provide web archives and RSS feeds (now including message extracts), updated in real-time, for many of our favorite lists.

[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

TXT records are decoded into VID,...

[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:

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,

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,

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...

Bugtraq — The premier general security mailing list. Vulnerabilities are often announced here first, so check frequently!

Security Basics — A high-volume list which permits people to ask "stupid questions" without being derided as "n00bs". I recommend this list to network security newbies, but be sure to read Bugtraq and other lists as well.

Penetration Testing — While this list is intended for "professionals", participants frequenly disclose techniques and strategies that would be useful to anyone with a practical interest in security and network auditing.

Info Security News — Carries news items (generally from mainstream sources) that relate to security.

Web App Security — Provides insights on the unique challenges which make web applications notoriously hard to secure, as well as attack methods including SQL injection, cross-site scripting (XSS), cross-site request forgery, and more.

Daily Dave — This technical discussion list covers vulnerability research, exploit development, and security events/gossip. It was started by ImmunitySec founder Dave Aitel and many security luminaries participate.

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

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...

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
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...

Reduce complexity, duplication, and scope in your infrastructure. Your

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
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.

root-project/root (ROOT, the CERN C++ scientific computing framework)
version v6-40-00 and below. The issue was confirmed end-to-end against
the real ROOT library (v6-36-04, snap root-framework) with a
deterministic 3/3 reproducer.

I am requesting that you coordinate a CVE assignment. The maintainers
confirmed the bug and merged a fix, but declined to classify...

Re: Coordinated Disclosure in the LLM Age ROI AI (May 24)
suspecting that LLM-detected vulnerabilities

I replied to this thread because I reported a dozen issues to OpenStack, which the OP is a VMT lead for. He has yet to
claim any of the issues I've reported are invalid or duplicate. I believe people are overclaiming this. I also believe
duplicates, when found, are a good sign for prioritization.

I was also disappointed to see a serious security bug I reported on OpenStack pushed...

Yes, reporting issues without proper analysis is and always has been grossly negligent. For that I strongly encourage
people to fight fire with fire. AI assisted reports should always go into a queue which utilize agentic analysis. I
can't stress enough how effective this and we should stop shaking our fists at the inevitable.

Everyone also needs to appreciate the amount of donated tokens and money. When I reported my dozen...

Hello,

Thanks for sharing this incident with the community. On May 17, because of an incorrect filter configuration, routers
of AS202734 exported a number of prefixes from its internal routing table to the route collector of the Hurricane
Electric BGP looking glass (bgp.he.net).

For BGP sessions with upstream transit providers (real routers), AS202734 uses a tighter set of filters, and export
only prefixes that are within a small number of...

Tom,

Thanks for your perspective. I do appreciate the Hanlon's Razor point —
it's a good general principle.

However, in this case, the same ASN also:
- Manually injected China Telecom's IPv6 backbone (`240e::/20`) into its
BIRD config on May 1
- Submitted a new ASN (`AS402333`) on May 16, the day of the leak
- Maintains a global geofeed that still lists a Shanghai node as of May
22

If that's not malice, then perhaps...

Re: [BGP Hijack] AS202734 - Follow-up on the HE-only visibility Tom Beecher via NANOG (May 22)
As part of BGP scaling and convergence testing I do, I essentially simulate
the entire public internet, with all usable IPv4 space as part of it. I
perform those tests in an airgapped lab environment with no possible way
for those announcements to leak out into production networks or beyond.
Even if someone broke the airgap, it would take multiple config changes at
multiple layers with specific intent for anything to leak out.

Not every network...

Yanzheng,

Thank you for this clarification. This is the missing piece I've been
trying to find.

So, to restate what you're saying, the 3,948 bogon routes were real
(AS202734 did import them into its BGP table), but they were only leaked
to HE's collector(s) and not propagated to the global DFZ. This explains
the discrepancy between HE and RIPE RIS data perfectly.

This also answers Charlie's question about...

Re: [BGP Hijack] AS202734 hijacked multiple Chinese Carriers on May 16-17 – Full evidence and attribution Tom Beecher via NANOG (May 22)
Zhong-

As has been pointed out already, when a suspected hijack/leak only appears
on a single route collector, with no evidence that any other ASNs/upstreams
received/accepted those announcements, common sense should tell you that
perhaps no leak or hijack occurred.

It is quite common for individual route collectors to see something that
appears like a hijack or leak, but the context matters.

Hopefully this is a valuable lesson for you going...

Re: [BGP Hijack] AS202734 hijacked multiple Chinese Carriers on May 16-17 – Full evidence and attribution Yanzheng Sun via NANOG (May 22)
Dear Zhong,

After analyzing the routing data and verifying the incident with AS202734’s NOC, this was not a DFZ-wide BGP hijack.
The invalid announcements were visible only on bgp.he.net due to a route collector filtering issue and were not
propagated to the public Internet, with no evidence of upstream acceptance or actual traffic attraction.

A route appearing on a single collector is not sufficient evidence of Internet-wide propagation,...
