Sadly, taking away valuable disclosure avoidance tools doesn't make fundamental trade-offs go away.
The US House reading Dutch emails shows digital sovereignty is about who can access data, not just where it is stored.
An AI agent tried to join the DN42 hobbyist network to perform a network scan, and bankrupted its operator with a $6531.30 AWS bill, to the extent that they are begging for donations from the DN42 community.
Following backlash, AMD agreed to fix an MITM RCE I discovered in Ryzen Master. All in all, it took them over four months to roll out the fix.
Today, I loaded the 1,000th data breach into Have I Been Pwned. Reflecting on that milestone number, I pondered how to mark the occasion in writing, and what immediately came to mind was a very simple question: why is it still needed? Especially considering the emergence of privacy regulations
Meta fixed the bug that let anyone trick its Meta AI chatbot into resetting the password on Instagram accounts that didn't have two-factor authentication.
In order to avoid accuastions of this "just being Claude defending Claude," "AI slop," "probably all hallucinations," etc., I've decided it's probably worth explaining a few key points about how this report was created:
Stella is the companion app for Meta's smart glasses. Inspecting version 273.0.0.21 of the Android build (com.facebook.stella), I found the entire computational and storage stack for on-device facial recognition: three face models, a local database schema, a cosine-similarity vector index dimensioned to
As a part of my work I do security research for various apps and websites. I wanted to see if LLMs could reproduce a common class of exploits I've found in multiple apps. So I built a deliberately vulnerable book review app and spent $1,500 finding out…
Abusing an unauthenticated Bluetooth protocol to turn a PC speaker into a Rubber Ducky.
My blog, mostly about programming
Yesterday, a slew of Instagram accounts, including some high profile ones like the Obama White House account, seemingly got hacked.
Since about a week, Cloudflare Turnstile (their "Verify you're human" device verification) has been looping indefinitely in my webkit-gtk based browser . Preventing access to quite few websites ( previously , but it even went worse lately). Turns out it's because Cloudflare wants to have a fingerprint of your device…
Transport Layer Security (TLS) is the protocol involved in getting the lock icon to appear in your browser next to the URL. Under the hood it uses a bunch of really cool numbers for encryption. Some numbers are considered private and need securing; some are considered public and are fine for sharing. You can mix your…
Update August 11, 2026: A group of researchers from all over Europe were inspired by this post, and actually turned it into a real working attack! Check out their writeup and paper here. This is a …
There is a moment in every investigation where the thing you have been looking for finds you instead.
Update: this post generated some interesting discussion on Hacker News. Friendly fraud is the laundered name for something that the payment system is not really able to prevent. Even though I’m pretty sure they can do way better. Particularly big and sophisticated payment providers like Stripe, with a mountain of…
Authorities in the Netherlands have arrested the co-owners of two related Internet hosting companies for operating IT infrastructure used by Russia to carry out cyberattacks, influence operations and disinformation campaigns inside the European Union. The two men were the focus of a 2025 KrebsOnSecurity story about…
The no-bid deal is five times the size of the agency's previous contract with the Massachusetts company and could put devices in agents' hands by late June.
This is going to be a rant about modern web design practices. But before I get to that, let me begin with a familiar principle from the world of cryptography. Among software developers, and especially among those who work on security-sensitive systems, there is a well-known maxim: Don't roll your own crypto. This does…
Oura users' data is not end-to-end encrypted and can be handed to the government. Will the wearable tech maker say how often it turns over data?
Lawmakers in both houses of Congress are demanding answers from the U.S. Cybersecurity & Infrastructure Security Agency (CISA) after KrebsOnSecurity reported this week that a CISA contractor intentionally published AWS GovCloud keys and a vast trove of other agency secrets on a public GitHub account. The inquiry comes…
Every end-to-end encrypted messenger ships a fingerprint UI. Almost nobody opens it. A note on what's actually missing.
Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files…
Behind a cheap Temu doorbell sits an IoT backend where device IDs are sequential and requests are forgeable with a string baked into every firmware. One signed call lifts any device's persistent password and lets anyone on the Internet hijack the next live call.
Back in March, I wrote about Bitwarden doubling their Premium price — and specifically how they did it. Buried in a feature announcement. Priced in fake...
Why frontier AI has broken the open CTF format, hollowed out the scoreboard, and made competitive CTF performance a weaker signal than it used to be.
The actual queries I run when I'm hunting fraud in transaction data. Velocity, impossible distances, suspicious amounts, merchant clusters, off-hours buys, and window functions.
Update 5/29: Mullvad has begun rolling out a mitigation feature on their servers that scrambles exit IP positions, thereby fixing this issue. IPs are still deterministically selected based on the pubkey. Mullvad is one of the few VPN providers that offers multiple exit IPs for its servers. If two people connect to the…
