i can finally share the google docs attack poc from my slides!!

blogpost coming later

(video 1/2 - the attack)

🔴 We just published our Black Hat Arsenal talk (part 1)!

It's a brief tutorial on:

1. using rev.ng from the CLI;
2. playing around with the decompiled code in VSCode;
3. finding bugs with clang static analyzer! 🦾

I didn't know how to explain it at the time but we have words for my bug report now: I used the SSDP RFC -> LLM-generated EBNF grammar -> vibe-coded Rust compiler for EBNF to Protobuf -> vibe-coded C++ frontend -> vibe-coded root cause -> vibe-coded report https://issues.chromium.org/issues/40070891

So I just reported a very interesting bug in Outlook - took me a while to analyze and understand (part of) the root cause..

The bug allows to read the value of an MAPI property* and use it *directly* as a memory pointer. We know OOB (e.g. caused by integer overflow) bugs are not rare but they're all some sort of "offsets", not someone just read the value and directly use it as a pointer.. So basically you can set the DWORD 0xdddddddd in the email and Outlook would happily access memory at 0xdddddddd. Not sure what severity it could be as it's an OOB-read at first glance, but def. an interesting find for me.:)

Full details will be released after MSRC's review.

The crates.​io team was notified of two malicious crates (with similar names as legitimate crates) which were actively searching file contents for Etherum private keys, Solana private keys, and arbitrary byte arrays for exfiltration. The malicious crates have been removed.

I wrote an article about what I wish juniors in cybersecurity would ask for and contribute when asking for a mentor and career guidance, in light of the terrible tech jobs market.

You just don't understand the fourth industrial revolution

"CVE-2025-1727 reveals a critical design flaw: the EoT/HoT linking protocol — which sends emergency brake commands [to trains] over a radio channel — has no cryptographic authentication."

🚨 SolarWinds, the gift that keeps on giving: a new Web Help Desk patch bypass, CVE-2025-26399, enables unauthenticated RCE via deserialization.

It’s a patch bypass of CVE-2024-28988/CVE-2024-28986 - previously exploited.

Given SolarWinds’ past, in-the-wild exploitation is highly likely. Patch now.

[RSS] BYOVD to the next level (part 1) -- exploiting a vulnerable driver (CVE-2025-8061)

Help, I need a code signing certificate that won't bankrupt me.

Three years ago, I paid $100 for a three-year code signing certificate. I've signed all my open-source projects' releases with it. Now that it's renewal time, Certera (SignMyCode.com) wants almost $700 for the same three-year certificate (excluding the mandatory HSM purchase, which I am totally on board with).

I write silly C and PowerShell code, and I timestamp my signatures so that they're perpetually valid. My PowerShell Gallery stuff, as well as binaries of aprs-weather-submit on Windows and macOS, are all signed and hashed (but not notarized by Apple, because that's another $99 a year for something that feels done unless Bob Bruninga's followers are thinking about APRS 2.0).

If I can't find a solution, anything I write or update in the future will have to be released as unsigned unless I half-ass something (like the Notepad++ developer using self-signed certs -- semi-dangerously clever). $100 every three years, fine. $700 every three years, and I'll do it if my three fans click my Buy Me A Coffee link over and over.

Is there any CA out there that will offer open-source, not-for-profit developers like me a chance to get globally-trusted code signing certificates? I don't think SigStore ever took off (sadly), and even if it did, I don't think it's part of the Microsoft Authenticode program.
