Trying to talk a customer out of buying firewalls for their MPLS transport network. They'd do better to invest the time in hardening, monitoring but apparently that's too hard.

Excellent DR exercise last week after the DC caught fire. Now, I do parallel backups so wasn't directly caught out but it turns out the corporate backup solution doesn't notify on failure. This seems a gap.

Gotta love IT. copy.fail directions that use perl and curl to apply patches. Not only elite UNIX knowledge but the patching command rhymes. We must curl the perl.

For all the AI hype, I'm absolutely fascinated to see more bug content that focusses on the mass of internal, commercial, compiled code that runs businesses. Most of the disclosures thus far appear to be for open source, where we should assume the models know the code, have seen the bug reports and have access to the patches but that's really not the reality of "interesting" enterprise software.

"We're all doomed. GlassWing can read source code and find vulnerabilities."
If the adversary has access to the source code, then they already somewhat could. They will still have to sort the wheat from the chaff no matter if they're using grep or some new super intelligence because not every bug ends up being exploitable. Also, how many controls have they subverted to get there...

Discuss: x isn't a security boundary because ... (where x is represented in https://attack.mitre.org/datacomponents/ or other control lists).
Counter point: Anything that changes the profile of the attack surface and presents an opportunity for detection can be considered a security boundary. Some may be more effective than others, some may have bugs, others may be configured badly but they all have some boundary value. The point of a security test is to point out the bugs and misconfigurations.

Particularly like the "Waiver required for all participants"... Presumably this means that if someone turns up shooting, it's on individual attendees heads... Bold move, "you might get shot, but that's on you...".

Hmm. Just got invited to Guns & Cyber by virtue of our CREST membership. I'm sure for some this would be a very welcome invite but not really one for me. Should I follow my personal ethics and make a complaint that I'm not really all that keen on shooting things and ask if they have an alternate event for people who would prefer to help people?

Forget about the intricacies of the DNS spec. This should have seemed like a bad life choice in any event. Turning user input into a command line when all you really wanted to do was write a 0 byte file:
sprintf(acfcommand, "/bin/touch %s/control/notlshosts/'%s'",
info->pw_dir, partner_fqdn);
fp = popen(acfcommand, "r");
