npcap 1.50 receiving too many packets.
Michael D. Lawler (Jun 24)
This worked fine with 1.31 as the number of sent and received packets
were equal. This is with Win 10 19043.1081. Let me know what I can
do to help. Also notice the results are not always the same I show
two runs below.

Re: Error getting nmap to read hosts from file

Not with nmap, but I've seen similar issues with other tools so recognised
that type of error.
Glad it is fixed.

Re: Error getting nmap to read hosts from file
Kurt Buff (Jun 08)
Genius.
Notepad said it was UTF-16 LE. I changed it to ASCII and it's working.
This was an export from our SIEM as a CSV in UTF-8, from which I extracted
the hosts with PowerShell and lightly edited with Notepad++. I suppose
somewhere in there it got converted, probably by PowerShell.
Definitely something to keep in mind.
Thank you very much.

Error getting nmap to read hosts from file
Kurt Buff (Jun 08)
All,
I'm getting an error trying to run a simple scan with Nmap, as shown.
Running in a CMD session on Win10 20H2. Scans with Zenmap work when not
using a file, as does Nmap. It's just when trying to use a file that I get
this very strange output. I've upgraded npcap from 1.10 to 1.31, and get
the same behavior out of both.
Am I doing something ignorant/stupid, or have I stumbled upon a bug?
Further information gladly provided....
Re: NPCAP GitHub Security Advisories
Daniel Miller (May 04)
I would like to add a clarification on the libpcap CVEs: since libpcap is a
user-mode DLL (wpcap.dll in the Npcap installation), it is not capable of
crashing the entire system. Instead, the impact of any CVEs would be
limited to the application and user that is using the DLL. For specifics on
the particular CVEs addressed, see the libpcap changelog at
https://www.tcpdump.org/libpcap-changes.txt

Re: NPCAP GitHub Security Advisories
Gordon Fyodor Lyon (May 01)
Hi Jay. Good questions, and I'm glad you like Nmap and Npcap! We are not
using GitHub's security feature at present. If we issued a security
advisory for Npcap or Nmap, we would likely host it ourselves. But Github
adds that tab to all projects by default and, from a quick glance at
settings, I don't see an obvious way to remove it. I think your best bet
is to sign up for release announcements through GitHub and look for...

Nmap Bug in payload.cc: corrupted UDP packets during -sU scan
mzet via dev (Apr 02)
Hi List,
It was observed that UDP packets that are sent during an UDP port scanning (-sU) are corrupted.

Re: Empty do_ipv4 function in address-info
nnposter (Mar 27)
I agree that there is no obvious reason why to have the function there

In other words, there should be no expectation that the script does
anything with IPv4.

In the current version of address-info.nse the do_ipv4 function body is

least expect a comment that explains why the function doesn't do anything.

Npcap 1.30 Released: Raw WiFi + Better Performance

Hi folks. The Nmap Project is pleased to release Npcap Version 1.30 at

happy with the raw WiFi improvements, since you tend to be particularly

bugs in our driver. Oops! But at least that means we can fix them

Re: Fully Automated CONOPs Exercise
Dave Aitel via Dailydave (Jan 28)
I mean, the goal of the question is to start putting some meat on the idea
of what "harm" is and how that is reflected both from a policy and
technical perspective. But also: It's useful to put some real definitions
around what is required to make people comfortable with fully-automated
techniques.
I don't think the idea that we are going to come up with and enforce norms
is as useful as figuring out what the norms really are...

Did any of them mention international humanitarian law, specifically
discrimination, respecting territory of neutral ("green") actors and
their infrastructure, and avoiding harm to neutral third parties and

accurately discriminate targets and resulting harm. This is an area
where technical experts need to be balanced with operators and policy
makers to ensure that...
Fully Automated CONOPs Exercise

So one of my new fav questions to ask policy teams is what they would do if
they were told to switch their offensive team entirely to worms. Nothing
else. Just worms. What needs to change to make that happen - from op tempo
to supply chain to personnel to policy and technological investment.
And how would their defensive team need to change strategically if they
were facing such an offensive team.

Re: The Lost Decade of Security Metrics
toby via Dailydave (Jan 05)
I don't think you are wrong but your comparison of CVSS and the multiple
(also separately bad) metrics for a WAF isn't effective or accurate.
The values going into CVSS have something in common; they are attempts to
characterize the importance of the vulnerability in question. You are
making (have made before) the claim that the importance of a vulnerability
is too variable and specific to an environment or an attack scenario to be...
Re: The Lost Decade of Security Metrics
Chuck McAuley via Dailydave (Jan 05)
Throughput* is perhaps the wrong unit of measure. Most of the time you would be interested in measuring
“requests/second” or “transactions/second”. Aside from say a content ingesting site/repeater
(facebook/twitter/instagram), almost all content for a WAF to handle is inbound, using low amounts of available
bandwidth. The outbound content is rarely inspected by such a device, with the exception of 5xx error or similar
(headers).

CVE-2021-3600 - Linux kernel eBPF 32-bit source register truncation on div/mod
Thadeu Lima de Souza Cascardo (Jun 23)
It was discovered that eBPF 32-bit div/mod source register truncation could
lead to out-of-bounds reads and writes in the kernel.
It was introduced by commit 68fda450a7df ("bpf: fix 32-bit divide by zero"). It
was first introduced in 4.15-rc9, but backported and applied to v4.14.y, v4.9.y
and v4.4.y. However, this specific attack will not work on v4.4.y and v4.9.y
kernels as pointer arithmetic is prohibited on those kernels. This was...

[CVE-2021-33624] Linux kernel BPF protection against speculative execution attacks can be bypassed to read arbitrary kernel memory
Adam Morrison (Jun 21)
The Linux kernel BPF subsystem's protection against speculative
execution attacks (Spectre mitigation) can be bypassed.
On affected systems, an unprivileged BPF program can exploit this
vulnerability to leak the contents of arbitrary kernel memory (and
therefore, of all physical memory) via a side-channel.
The issue is that when the kernel's BPF verifier enumerates the
possible execution paths of a BPF program, it skips any branch...

Re: Can somebody explain these ransomwear attacks?
Jakob Heitz (jheitz) via NANOG (Jun 26)
Finding vulnerabilities and how to exploit them to run malware

Anyone can read open source code.
What is possible is to analyze patches to figure out what was fixed
and then to attack those that didn't apply the patches.
Even easier is old releases. Patches often have more than one fix,
but a patch for an old release is almost guaranteed to be a fix
for a single vulnerability. That makes it...

I don't know. I'm trying to figure it out too.
I just know that the less diverse an ecosystem, the more vulnerable it
is to destruction. Heterogeneity (and change, by the way, i.e being a
moving target) mitigates against the risks of a monoculture.
Homogenous, centrally managed, massively networked systems bring many
benefits, but we are now seeing the sorts of weaknesses it brings, too.

Re: ASN.1-based dissector decoding by port number vs switch/case using 1st octet
Guy Harris (Jun 26)
So this isn't really a Wireshark dissector question, it's a protocol design and encoding question.
The issue isn't "how do I get a Wireshark dissector to distinguish between different message types without giving each
message type its own UDP port", it's "how do I get *the recipient of the messages* to distinguish between different
message types without giving each message type its own UDP port" - this...
Re: GRegex deprecated
Gerald Combs (Jun 25)
Has this change actually been committed? It looks like GLib's internal copy of PCRE was removed in

but meson.build still requires an external libpcre in GLib's main branch.
As MR 1451 points out, PCRE1 is in maintenance mode so it might make sense to migrate to PCRE2.

Re: ASN.1-based dissector decoding by port number vs switch/case using 1st octet
Vincent Randal (Jun 22)
The protocol does not exist yet.
Neither. I am helping develop this protocol for IEEE 1451.0. I do not
represent the IEEE. I am simply volunteering (as others) in one of the
working groups (IEEE 1451.0).
Why on earth did I choose to use ASN.1? Because I was asked to provide some
form of IDL for the messages, and I found esnacc and omiidl in Linux as a
means for translating ASN.1 to IDL and syntax checking it. So then I
decided it was worth it...
Re: ASN.1-based dissector decoding by port number vs switch/case using 1st octet
Guy Harris (Jun 22)
You should be using whatever encoding the protocol is using.
Is this a protocol for which you have an ASN.1 specification plus an indication of the encoding being used, or is this
something you're reverse-engineering?
Re: ASN.1-based dissector decoding by port number vs switch/case using 1st octet
Vincent Randal (Jun 22)
We are using PER per the foo example (Simple ASN.1-based dissector). Wow, I
never about all these different encodings.
Maybe we should be using something other than PER? We think we like PER
because the dissected values agree with what we can see in the raw UDP data.
Re: ASN.1-based dissector decoding by port number vs switch/case using 1st octet
Guy Harris (Jun 22)
"ASN.1-based" in what sense?
If the data to be dissected is *entirely* specified by an ASN.1 specification, using one of the representations for
ASN.1, then the way it should decode the first octet depends on the representation - BER or one of its derived variants
(DER, CER), PER or one of its derived variants (CPER), XER, OER, etc..
...and which does not appear to use any ASN.1 encoding, so it may not be relevant in your case.

Re: Struggling to build NSIS installation
Gerald Combs (Jun 22)
As far as I can tell, Chocolatey doesn't support alternative package dependencies, so you get too choose between
depending on a specific JRE (which might install an unwanted extra copy of java.exe) or none (which requires an extra
installation step). The AsciidoctorJ package went with the latter. I've added a note about installing a JRE separately
to the Developer's Guide in MR 3441.

Also, the answer is “because you can’t do a relative match to something that doesn’t exist (distance:1; within:10;)”.
So, in order to do what you want to do, you have to do the positive match and then read backwards. Which is why I ask
