Zenmap wrong ptr Scott Mayoral (Feb 04)
Hello,

While using zenmap (Mac OS) and ran a number of scans on the ip 165.232.151.85 (my client's server which I manage) and
the ptr returned is cr1osbydoe.com <http://cr1osbydoe.com/> When I run a dig -x on the terminal, the correct ptr
appears (hncda.livinginarchitecture.org <http://livinginarchitecture.org/>), same correct results from nmap proper on
my PC, as well as on the PC command line. crosbydoe . com is a url on...

Re: NMAP Scan help Jon Gorenflo (Feb 04)
Seeing JavaScript comments during an NMAP scan can indeed be a concern for clients with proprietary information. The
best way to protect this information is to not include it in the source code of the website. If it is absolutely
necessary to include it, it can be obfuscated to make it more difficult for an attacker to understand, but it cannot be
completely protected from being seen during a scan.

Yes, the JavaScript is sent to the browser as part of the "web page

Re: NMAP Scan help Robin Wood (Feb 04)
JavaScript is sent to the client as part of the way the web works and so
can't be blocked or hidden. If you stop sending it then whatever bits of

Nothing should be considered secret in client side JavaScript.

PR: NSE Script: Oracle NNE Crypto Parameter Enumeration Moritz Bechler via dev (Feb 04)
Hello,

a while back I did some reversing and security analysis on Oracle database's
proprietary transport security protocol (NNE/SNS).
Based on that research I have put together a NSE script that determines the
NNE server parameters/configuration and identify weak/vulnerable instances.

Happy to contribute that to nmap, I have opened a PR: https://github.com/nmap/nmap/pull/2603

Proposal for a new feature to Ncat codergaz (Feb 04)
Hello,

First of all, I wanted to thank you for your work in developing great software. I use Ncat on a daily basis and it is a
must have tool for services management. And I would like to contribute to the project.

A very useful feature would be for Ncat messages to have a timestamp, to know when connections have been established.
Especially in listen mode, but also in connect mode.

Possible minor erros in nmap-os-db João Medeiros (Dec 23)

I was parsing nmap-os-db for research purposes and found 3 empty

Good morning, dear friends.

I would like to share that I've updated the RadialNet tool [1] to work

any bug I did not notice.

To test you may execute a Scan using Nmap as a backend tool (initially
assumed to be on /usr/bin/nmap, but can be changed in config.cfg). You
may also test it loading any Nmap XML output file (a sample is
included in share/sample/nmap_example.xml)....

CVE-2023-1075 - Linux Kernel: Type Confusion in tls_is_tx_ready() Pietro Borrello (Mar 01)
Hi all,

I am disclosing a type confusion in the net/tls stack of the Linux Kernel.

However, this condition can never happen.
For an empty `tx_list`, list_first_entry() returns the list_entry() of the head,
which, when used, is a type confusion.
Thus, tls_is_tx_ready() may potentially use a type-confused entry
to the list_head, leaking the last byte of the type confused field...

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Mark Andrews (Mar 08)
Correct, you can’t use 100.64/10 for any service expected to be reached
by customers. CPE shouldn’t see traffic from 100.64/10 with the possible
exception of ICMP ERROR messages. Even advertising a 100.64/10 address as
next hop is problematic for dual homing CPE.

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) William Herrin (Mar 08)
Hi Lukas,

Thanks for the clarification. As others have said: the error lies in
the base conditions of your reasoning, not team-cyrmu's bogon list.

The bogon list is designed to be used unmodified at one particular
kind of location only: the BGP-speaking link between two different
Autonomous Systems. Anywhere else you might choose to use it, you must
first exclude or override the filtering for locally used addresses.

Perhaps the folks...

I>'d say that they shouldn't send them to her without her acknowledgement

Exactly

We use CGNAT in our network unfortunately. We skip CGNAT for internal resources only, to reduce logging, load, etc.
but all outbound and/or customer to customer traffic goes through the CGNAT. Only public IP addresses are allowed to
communicate between customers.

I argue that Alice should expect to not receive any traffic from
non-globally routed IPs UNLESS her cloud provider has informed her that
she should expect them.

I'd say that they shouldn't send them to her without her acknowledgement

I disagree.

Nothing prevents someone from filtering bogons without using RFC 6598 as
justification to do so.

I suspect that there are many people using DFZ feeds that...

NY Verizon FIOS IPv6 routing issue Robert Blayzor via NANOG (Mar 08)
Any Verizon IP engineers lurking on this list that can contact me about
a recurring and chronic IPv6 routing issue in the upstate NY Verizon
FIOS network. Getting feedback from several customers that have valid
IPv6 PD from FIOS but routing is broken 2-3 hops out in Verizons

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Tom Beecher (Mar 08)
Respectfully, this is exceptionally ignorant.

Team Cymru is not misrepresenting anything. They are very specific and
detailed about which addresses the bogons and fullbogons lists contain.
They also clearly state that individual networks MAY need to make
adjustments based on their circumstances.

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Victor Kuarsingh (Mar 08)
This was the intention of the RFC. As this space was intended to be used
with an AS's network to service CGN needs. That CGN boundary likely ends
before a given customer and/or neighboring network, so it would make sense
that downstream and neighboring networks would filter at their borders.
All that said, if for some reason, a downstream network has 100.64/10
assigned to direct links on an interconnection, that may be a problem.
That type...

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Lukas Tribus (Mar 08)
You know all this if you are the network operator.

If you are the customer of the ISP, let's say a datacenter/cloud
customer and you are deploying Web or Mailservices, you have no idea
whether this ISP will route RFC6598 traffic to you or not and you
certainly will not get informed by the ISP if that ever changes. You
only know about this once you are dropping production traffic from
clients in 100.64/10 and a trouble ticket has found...

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Lukas Tribus (Mar 08)
It very much is.

An autonomous system can contain both "eyeballs" (possibly RFC6598
adressed) and services in datacenters/clouds, it's not *always* a
different ISP.

Perhaps I should have started this topic with a very specific example:

- ISP A has a residential customer "Bob" in RFC6598 space
- ISP A CGNATs Bob if the destination is beyond it's own IP space
- ISP A doesn't CGNAT if the destination is within...

Re: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Lukas Tribus (Mar 08)
Absolutely, everybody's free to drop whatever they like on their gear,
I'm sure there are networks, gear, applied and documented
configurations out there that block 1.1.1.0/24.

That doesn't mean publically available blocklists need to misrepresent
their use-case.

The concern is not about networks that know what they are doing, the
concern is about the rest (and more specifically entities that don't
operate their own ASN)....

Re: Re[2]: RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all) Lukas Tribus (Mar 08)
Hello,

I disagree, authoritative and accurate product description and
documentation of the tools used by the public matter a lot. If a
ticket lands on my desk because a third party misuses a tool, I want
to point to a single authoritative source of information.

I know that, you know that. That doesn't solve my problem. What solves
my problem is accurate documentation and education.

This is an operational networking issue that goes beyond...

Healthcare organizations face rising ransomware attacks – and are paying up Matthew Wheeler (Jun 03)
https://www.theregister.com/2022/06/03/healthcare-ransomware-pay-sophos/

Healthcare organizations, already an attractive target for ransomware given
the highly sensitive data they hold, saw such attacks almost double between
2020 and 2021, according to a survey released this week by Sophos.
