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.

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

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...

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.

In preparation for an imminent Nmap release (hopefully this week!), we have

For OS detection, we added 336 signatures, bringing the new total to 6,036.

the number of organizations that you can rely on to actually make a

Some telnet clients leak environment variables Justin Swartz (Mar 13)
Greetings,

In a recent oss-security thread [1] regarding the CVE-1999-0073 [2]
regression in GNU inetutils telnetd, Solar Designer suggested [3]
that the inetutils telnet client may not have been subject to an
adequate fix for CVE-2005-0488. [4]

If this were the case, then it would mean that a telnet server could

That's right.

No, we follow C's rules in this respect. Pointers can't point outside
the addressed object (except that that they can point to the very next
byte and this exceptional pointer cannot be dereferenced).

That assumes that sizeof slcbuf is at least 6. Although that may be true
here, a safer idiom in general is:

if (slcbuf + sizeof slcbuf - slcptr <= 6)

This cannot overflow, if slcptr points within the buffer...

Multiple vulnerabilities in AppArmor Qualys Security Advisory (Mar 12)
Hi all,

We will soon publish an advisory about multiple vulnerabilities in
AppArmor, but we first wanted to give an explanation and an apology.

We have been working on this for several months now, together with
Canonical's AppArmor developers (including AppArmor's maintainer, cc'd).
Once the patches were ready we contacted the Linux kernel security team,
and later the linux-distros list.

Unfortunately, problems were then...

Hi Hank,

It may also be Doha, the only way I arrived at the UAE conclusion is
RIPE Atlas measurements, and there is a Atlas probe 3 ms away within
the UAE:

But gcping is about Google Cloud regions, which is not necessarily the
