Praetorian is hiring for another 3 red teamers at the lead+ level of experience. Have to be lead or above for this hiring round, no junior or senior for the red team until next quarter, but there are other open positions on our website. We filled 29 reqs in Q1 and are scaling quickly but sensibly. Our clients have mature environments, you won’t have an easy life; but if you like to be challenged, this is a good place for you. **I am slow in DMs, best apply via our website but drop me a note

Which sounds more realistic? “If we do a few strategic things we kneecap the attackers” “We can do all the things everywhere all at once, 365x24 forever.” It seems like focusing our limited resources where it matters would be better. 3

My friend Krypt3ia is still searching for a remote CTI role after being caught in the layoff cycle. He's got years of solid experience and technical chops - including LLM training. If you've got leads, ping me and I can pass them along or share his resume. RT for reach pls.

First, I want to compliment @Microsoft for being forthright with details. Some of the problems I see in this report, I SEE EVERYWHERE due to VULNERABLE DEFAULTS. Let's start with creating malicious OAuth applications. By default, ANY USER can create app registrations and consent to Graph permissions as well as sharing 3rd party company data. In tenants where this is hardened, ability to create app registrations require Application Administrator or Cloud-Application Administrator and admins must consent to permissions used by the application whether local or from another tenant.

Howdy folks! I wrote another free Trimarc whitepaper on #ActiveDirectory Object Ownership. 50+ pages of PDF goodness on how ownership can be abused, how to discover non-standard object ownership, remediate it retroactively, & how to defend against it proactively.

Microsoft recently reached out to get my perspective of identity security (Active Directory & Azure AD). Here's the interview: techcommunity.microsoft.com/… TLDR: Many of the issues we have seen with Active Directory are in Azure AD as well from a customer perspective.

Without proprietary collection sources and methods, unique placement and access, what is the real value of a threat intel team at this point?

One of my biggest regrets was not contributing to my 401K with matching employer funds starting when I was 18.
Do NOT fuck this up if you can manage it financially. I've been contributing overtime recently and I'm still in deficit.
Go to your employee portal. Fucking free money

Thats the crazy thing us old timers know. The pen test we did 24 years ago reads exactly the same as one done today.

Based on what we have seen during Active Directory security assessments, if you have Active Directory Certificate Services (ADCS) in your environment, you want to download and run Locksmith to scan for ADCS security issues. Locksmith provides remediation as well!

This approach assumes that most relevant target orgs will have: 1. Fairly poor internal defenses against lateral movement & privilege escalation, imposing minimal delay. 2. No detection & response processes able to reliably, rapidly, and successfully stop even noisy intrusions.
