Tax The FRIGGIN RICH....

Quick note on giving talks. It is not enough to have great content. Expectations are low. When you start off, quickly establish some kind of bond with your audience. Once that is in place, your listeners will give your presentation a decent chance: berthub.eu/articles/pos...

Rubio publicly criticizing an ally for cracking down on right-wing extremism. And Germany hitting back. We are in a new world

We already know that any Web server listening on the loopback interface is a security risk, because it may be accessed by a browser or its extensions. But the impact may be way bigger if this Web server is a MCP server 😱 blog.extensiontotal.com/trust-me-im-...

I don’t understand why DOGE’s access to critical data isn’t a scandal by itself 🤔 www.npr.org/2025/04/15/n...

AppSec Ezine - 585th edition pathonproject.com/zb/?44122470...

Just finished the book "THIS IS HOW THEY TELL ME THE WORLD ENDS" by @nicoleperlroth.bsky.social A great view at the people finding, selling or using 0-day vulnerabilities A few friends appear here and there, and that make the book even better

If there's one thing I've learned about covering cybersecurity over the past decade or so, is that the cybersecurity community (the fixers and breakers) and the cybersecurity industry (profits above all else) are two very, very different things.

@stokfredrik.bsky.social This one is for you!

My device is safe (as of today’s public techniques), but I should nonetheless use my USB condoms more often when traveling arstechnica.com/security/202...

If you like hacking XML, this article is a gold mine! 😱 It includes parser discrepancies, round-trip attacks and my favorite, namespace confusion 🤩

NEW: In an 11th hour move, CISA spokesperson says the agency extended the contract for the MITRE-backed CVE Program last night:

In case you missed today's *HUGE* news, the funding for the CVE and CWE projects is "expiring" today 😱 Yes, you read it right... www.youtube.com/watch?v=itbs...

3 milliseconds to admin — Our analyst John Ostrowski turned a DLL hijacking into a reliable local privilege escalation on Windows 11. He chained opportunistic locks, and API hooking to win the race to CVE-2025-24076 & CVE-2025-24994. Read his blog post: blog.compass-security.com/2025/04/3-mi...

Le Mont Saint Michel Rising from a sea of low fog… Captured Friday morning in this iconic location, which happens to be super close from my home. #photography #art #landscape

💥 Whopper scoop from @andybounds.bsky.social: Brussels is issuing burner phones & basic laptops to commissioners & senior officials travelling to the US for IMF/World Bank spring meetings next week to avoid risk of espionage — a measure traditionally reserved for China. www.ft.com/content/20d0...

Went on Wicked Words to talk all about DARK WIRE, my book on the incredible true story of the biggest sting operation ever in which the FBI secretly ran a tech company for organized crime. Years later still nothing has come close podcasts.apple.com/us/podcast/j...

I will definitely not attend or speak at any US event in the coming years—not that I liked Las Vegas in the first place—and I’m wondering how common that will be. There are only a few speakers making a living out of it so I assume that CFP review boards will have noticeably less submissions? […]

From what I hear, everybody is reconsidering their stays and stop-overs in the US... From an European PoV, that means less people going to @blackhatevents.bsky.social or @defcon.bsky.social this summer, and more people going to @why2025.bsky.social 🏕️

We are in 2025, and both XInclude and XSLT are still useful (at least for attackers) gist.github.com/parrot409/e9...

I was pretty confident in my position, but your persuasive use of all caps and excessive punctuation made me realize I was wrong all along.

I do have quite a backlog of blog posts, so let's start with this one 😎

Another undercover FBI investigation related to cryptocurrency 💰
