About ListZenmap 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.

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

any bug I did not notice.
To test you may execute a Scan using Nmap as a backend tool (initially

may also test it loading any Nmap XML output file (a sample is

All of tcsh's uses of TIOCSTI are in `#ifdef TIOCSTI` blocks so tcsh

Re: TTY pushback vulnerabilities / TIOCSTI Hanno Böck (Mar 17)
This is interesting.
Given this works only on "virtual terminals" (aka not in a terminal
window on X, not over SSH), I think the severity is much lower than the
TIOCSTI issue. Still it should be fixed.
I've created a patch for the Linux kernel very similar to the patch

From a security perspective tossing out functionality is the better
option compared to restricting access. If there is practically no use
of that functionality and it's mostly a security risk, then removing it
is the right choice.
Reducing complexity is a good principle for IT security.

In Solaris we've changed how TIOCSTI works; when a process reads the

echo Payload as `whoami`

But when having root calling tciosti, you get:

Request for additional data points Etienne-Victor Depasquale via NANOG (Mar 10)
Good people,
Last year, I collected some data for my study from this list.
I published a summary of the data for a short time and
recently sent a snapshot regarding metro area access technologies.
I am currently writing my paper and would love to have some additional data
points.
If anyone who has ***not yet contributed***
would like to do so, I am still collecting data here:

Re: Is malicious asymmetrical routing still a thing? William Herrin (Mar 09)
Come to think of it, there are probably botnets for rent where the
"owner" has verified non-compliance with BCP38 and will arrange for X
number of fresh machines spread across everywhere to VPN into your
server and pass packets for you. Why not bring in a little extra cash
while waiting for the next DDOS target? Particularly when the packets
emitted are unlikely to be traceable to the bot.
Regards,
Bill Herrin
Re: Is malicious asymmetrical routing still a thing? William Herrin (Mar 09)
If I had to put money on it, it's not VPN providers but other VPS
providers. VPN providers don't have enough business that anyone cares
about to avoid getting killed over BCP38 non-compliance.
It's trivial to turn a $5 VPS into a disposable VPN head-end that can
spray TCP SYN packets at a modest rate, and once the packet is on the
backbone somewhere in the world not only can't you do anything about
it, it's just on the...
Re: Is malicious asymmetrical routing still a thing? Grant Taylor via NANOG (Mar 09)
I'd be curious what VPN providers they are using so that I could start
blocking them. That seems like another player in the criminal support
ecosystem.
Interesting.
Re: Is malicious asymmetrical routing still a thing? Grant Taylor via NANOG (Mar 09)
I would hope so too.
I also would hope that uRPF was enabled by default on SOHO routers.
And yet ... I'm routinely disappointed.
CADIA has a Spoofer probe project that tests this very thing. I see
periodic announcements to various mailing lists about their monthly
results. -- I'll find one if you care to know more.

Re: Is malicious asymmetrical routing still a thing? Christopher Munz-Michielin (Mar 09)
Not this exact scenario, but what we see a lot of in my VPS company is
people sending spam by using our VPS' source addresses, but routing
outbound via some kind of tunnel to a VPN provider or similar in order
to bypass our port 25 blocks.
We've had to start blocking source port 25 to catch the replies from the
recipient mail servers in order to prevent this kind of abuse.
