De nada sirve defenderte contra ataques automatizados con IA si luego el fin de semana Paco utiliza su portátil del trabajo para descargarse películas piratas.
Somos y seremos los principales culpables de los ciberataques.

This is bang on. At the pace this field evolves what is important is showing initiative, curiosity, the ability to learn and willingness to take on the less glamorous work.
If you work in IT and want to transition into cybersecurity do this:
Ask your boss if you can help with cybersecurity related tasks like vulnerability management, managing the EDR or web content filtering. Just a couple examples but my point is…
Don’t wait until you get a cybersecurity job, start now.

Genuine nightmare mode. I can defend against users wanting a free burrito coupon. I don't know how you stop someone interviewing for a fake $150,000 job on a corporate asset and doing whatever the carrot says.

Happy Wednesday Everyone!!
Now, we announce the final Golden #Clippy nominees for the #ChuckNorris Award. #RIP Chuck Norris, you've served us well.
Our 4 finalists are very special people that do amazing things. The Chuck Norris Award is for people who excel in multiple areas and make a major different in our industry.
Last year, this award was separated by ONE VOTE between @knudsenmortendk and @fabian_bader
🪄 Morten, the creator of @ExpertsLiveDK, incredible community advocate, and double threat in both #MSEntra and #MSSecurity has been making some amazing strides in Entra over the last year or so, with some
#PIM tools, and incredible sessions showing why he is the favorite to repeat in this category.
⛸️ @NathanMcNulty one of the biggest names across our industry of @PatriotExperts, is one of the most talented experts of several areas like #DefenderXDR, #GraphAPI, #MSSecurity, and everything else. His #MSEntra skills are just as amazing, with as a master of #Passkeys, #Identity, #authentication, and so much more. He's a master practitioner who is one of the "go-to" people when you have a problem no one else can solve.
🍺 @Bindertech, is another special technologist. One of #JNUC's favorite speakers. Simon can do so much, whether its #Apple, #iOS, #MacOS, #MSIntune in general, #Windows 365, and is just so incredibly brilliant. @advania is incredibly lucky, as he's continued to add more skills on the #AI and #Security #Copilot side. On top of all of that, he has become a #Nerdio #NVP in the last few years, and continues to grow his Chuck Norris-like versatility.
@SSkotheimsvik is another huge addition to the #WPNinjaSUS this year as one of the brilliant members of @TeamCloudWay, who is a nominee for a few different #Golden #Clippy awards this year. He excels in multiple areas and is one of the best speakers that our community has today. Simon has received awards from @SessionizeCom numerous times for most active speaker and has spoken on several areas like Security, Microsoft #Teams, Intune, #M365, and so much more. We're so appreciative of him joining us in Scottsdale!
Gentlemen, let's make our old friend Chuck Norris PROUD.
Don't forget to register now, because these tickets are GOING FAST, as we just sold out of the primary hotel, but still have some great space available in our 2nd hotel:

I love that people want to assume that I formed my opinions on the viability of current generation open-weight LLMs for enabling low-skilled criminals to find useful zero-day exploits, based on having just never used an LLM at all.
The first thing I did when Anthropic added me to their CVP was build an autonomous zero-day exploitation pipeline. I've since backported it to use open-weight models because the token cost was insane, so I have a fairly good feel for both current frontier and open-weight model capabilities.
I'm well aware of what LLMs are capable of doing, and that they can, with the right steering or harness find zero-day exploits. Where we drift off course is with the claim that low-skilled criminals can just pick up something like GLM and find viable zero-day exploits.
I think that:
a) More than 90% of CVEs are functionally useless for threat actors. Threat actors have a very specific operational needs and "random issue in random software" does not fall into their scope.
b) Many (quite possibly even the majority of) critical rated CVEs are not exploitable under real-world conditions in a way that is useful to threat actors. There's entire teams in China dedicated to n-day exploitation and watching them will give you a good feel for what percent of critical RCEs are actually useful.
c) Threat actor with no exploit development background and minimal technical skills, even with access to a completely unrestricted open-weight LLMs, would struggle or completely fail to find useful zero-day exploits.
d) People with very little experience in software exploitation, Large Language Models, and CTI, are watching professional vulnerability researchers working with next-gen frontier models and ending up with a wildly unrealistic beliefs of just how "easy" what they are doing is.
e) There is an extremely noticeable lack of both zero-day exploitation and use of novel (non-public) n-day exploits by all threat actors, especially unskilled ones, and proponents of the "anyone can just pick up GLM and find useful zero-day exploits" theory continually refuse to even acknowledge that fact, let alone attempt to explain it.
I'm not coming at this from the position of some dude who just logs on to social media to says uninformed shit. I'm coming at this from the perspective of a researcher who has spent thousands of hours since LLMs came out researching their capabilities, and has also spent their entire career tracking threat actors and their capabilities.
I have a mountain of real-world data, because the low-skilled AI-powered threat actors have a high tendency to accidentally infect themselves with their own malware. This often results in them exfiltrate their entire hard disk, along with all their AI prompt logs, to a vibe-coded C2 with client-side authentication (the admin credentials are hardcoded into the javascript or something equally stupid, so anyone can log in and download it).
My entire career I've been very pro "degrees and certs don't matter, everyone is welcome, and the best way to gain experience is hands-on practical work". But when I have some dude whose only experience is essentially just "downloaded abliterated GLM and scared himself with it", I feel like it's necessary to draw a line somewhere.
It's not just the bad opinions, everyone has bad opinions on something, I have plenty. It's that resources are actively being diverted away from addressing real and pressing issues in cybersecurity, as a result of FUD being spread about imaginary GLM-powered zero-day wielding scriptkiddies.

Special thanks to @techspence for teaching TISU cohort 9, educating us all on assume breach penetration testing, enumeration, hacking of active directory, and privilege escalation. It was one of our most iconic sessions of all time. The best part was that Spencer loaded a demo with extreme practical relevance, before I even did the intro. Instant Threat Intelligence Support Unit/TISU MVP status. 🤘
My only regret is that I could not have sent this session back to 5/10/15 years ago me - wish I knew some of this sooner. 🫶🤷♂️

Whatever you do, DO NOT ask who the CISO is if it isn’t already obvious!

Ask your boss if you can help with cybersecurity related tasks like vulnerability management, managing the EDR or web content filtering. Just a couple examples but my point is…

In case it helps, I recorded a short video showing common causes of this issue - all are related to your tenant config
This is called an interrupt - it happens because you don't have a suitable auth method, you need to register for SSPR, or a policy requires fresh authentication

The new NTLM signing security improvements in Windows look great and are long over due.
While all supported Windows Server versions are capable of NTLM signing; The new changes/update help ensure that signing is negotiated and eventually required by default.
Phase 1 (November 10, 2026): Windows client devices begin offering NTLM signing on all connections by default. Servers accept both signed and unsigned clients. Auditing events identify clients not using signing.
Phase 2 (May 2027): Windows servers begin requiring NTLM signing by default. Clients that do not offer signing will be rejected by secure servers.
Nice to see Microsoft begin making changes that don't just address single vulnerabilities but address entire classes of attack paths

Which AMSI providers are actually on your endpoints? Most teams have never checked.
A technique that changes how Defender picks its signatures doesn’t automatically silence every other provider. We tested it. The two didn’t match.
Registry commands to inventory yours and see which are actually inspecting content.

Solid advice. Also, by picking up bits at a time you’re less likely to burn yourself out. Keep in mind that it’s impossible for you to know everything about ‘all the things’. However, experiencing as much as you can will make you a well-rounded security professional.

When I started learning ethical hacking, I was so focused on tools, exploits and advanced attack techniques that I somehow overlooked the fundamentals.
After a while, I realised that understanding the basics is what makes you a better security professional.

🚨 During the past 24 hours, we have observed probing of N-able N-central for the 0-days that were dropped publicly yesterday.
We have seen opening of anonymous agent sessions, pulling appliance config and hitting the remote control endpoint without auth. These pathways are part of the 0-day exploit surface.
If you run N-central exposed, take it off the internet now.
