@zebriez British Special Forces uses the phrase "switched on."
News flash: your top security priorities in a world where attackers move faster thanks to AI tooling are... ...the exact same as they are today. CIS Top 20 is still the CIS Top 20. Execute those well, you'll be better prepared than your peers. And remember: attackers are lazy.
People shouldn’t be scared by this CrowdStrike report. I don’t even know why they added the “AI-enabled ransomware” part -probably a PR idea that nobody stopped The real issue is wrong risk perception. CISOs worry about what sounds new instead of what actually causes incidents.

Hey @LinkedIn - your newly aggressive notification preferences are so loud and your UX for disabling the types so tedious I am on the precipice of turning off all notifications from everywhere. That’ll make my experience worse, but right now lesser of two evils. Please fix.
A preview of what's coming soon from @SevcoSec. SO MUCH fascinating and never before seen data to dig through!
@jeremiahg @SevcoSec I was wrong. At least in this [one, small] sample it is ~25% differing results: One org, ~10k devices, ~21k total CVEs, two sources of CVEs. ~75% of those CVEs reported by both. More to come soon!

@jeremiahg @SevcoSec Overlapping. We’ll see what the actual numbers end up like, but in general I expect wider variance than most end users expect. Smaller variance on a single machine, increasing as count of assets compared increases.

📣 @jjguy will be talking Vulnerability Management & Asset Inventory at #ThursdayDefensive tomorrow. We hope to see you there! reconinfosec.com/thursday-defen… #cybersecurity
@secprentice @TheSharp0ne Here's a screencap from the console showing the overlap between Crowdstrike, Active Directory and SentinelOne. (lifted from a client during their migration from S1 to CWRD) sevcosecurity.com/book-a-demo/ or DM me to get rolling
Fixing this is @SevcoSec‘s mission.
In six months of working for an MDR that services all manner of industries, I feel like any time I see an incident occurring it started on an asset that didn't have EDR installed.
🧙♀️ CISO Story Time This is not exaggeration. I have a good friend. He's a CISO of a multinational organization in the technology sector. We talk often. Market trends, sales, and business regulations had the business decide to open an facility in China. a 🧵 👇
CISO: How many windows hosts do we have? Sevco admin: "9,618 between EC2, AD and S1. That good or do you need something more specific, boss?"
