From iframes and file reads to full RCE. 🔥

We found an HTML-to-PDF API allowing file reads and SSRF - then chained it into remote code execution via a Chromium 62 WebView exploit.

And the day is not over: Trying to fix some household stuff, I google for parts. First result is a recall notice claiming a dozen incidents with human injury o.O

(The part I was searching for was the cause of the failure too)

I struggled a couple of hours because my sshfs connections kept breaking, that made my browser hang in many different ways (fuse ftw!).

I suspected my router getting bust, but of course I was wrong. The problem - as always - was DNS.

I'm proud to announce that myself and @atipriyabajaj have created the Workshop on Software Understanding and Reverse Engineering (SURE), which will be co-located at CCS 2025. https://sure-workshop.org/

Please follow our workshop account @sureworkshop and RT it for visibility :).

Here's something counterintuitive to non-practitioners: curve P-521 is often less secure in practice than curve P-256.

The latter is more popular, and so better tested. The risk of implementation bugs dwarfs the risk of partial cryptanalysis of ECC, so picking P-521 optimizes for the wrong thing.

Intel's 386 processor (1985) moved the x86 architecture to 32 bits, but it needed to be backward compatible with earlier 16 and 8-bit processors. As a result, it needed complicated circuitry for its internal registers: six different circuits for 30 registers. Let's look at the silicon circuits. 1/N

🔐 The SLB 9670VQ2.0 FW7.85 SPI TPM module sounds like something your cat would type mid-zoom call — but it's actually a serious piece of security hardware.

This TPM (Trusted Platform Module) chip is used in motherboards and SBCs to store crypto keys, generate true random numbers, and keep your hardware’s trust chain tight, even if the rest of your system isn’t Fort Knox. TPM 2.0 is even a requirement for modern OSes like Windows 11.

TP-Link is CNA now.
