Drone Hacking Part 1: Dumping Firmware and Bruteforcing ECC Desoldering a drone's flash chip and reconstructing the firmware from broken data.

Drones are hot - their security is not.
Here is how removed the NAND, dumped firmware, and reverse-engineered ECC on a consumer drone. Stay tuned for part 2!

Thanks to @thezdi.bsky.social for hosting yet another well-run and inspiring Pwn2Own edition!

Another amazing #Pwn2Own in the books! 💪
Our team pulled off some great hacks:
🖨️ HP Printer — $20K / 2 MoP
🏠 Home Assistant — $15K / 3 MoP
🔌 Smart Plug — $20K / 2 MoP
📸 Canon — $10K / 2 MoP
Total: $65K / 9 MoP
So proud of what we achieved together! 🧠⚡

Verified! Team @neodyme.io used a single integer overflow to exploit the Canon imageCLASS MF654Cdw. Their unique bugs earns them $10,000 for the 8th round win and 2 Master of Pwn points. #Pwn2Own

Diving into the depths of Widevine L3 This post explores various approaches to attacking Widevine L3, a DRM system commonly used by streaming services. We analyzed the Android library and instrumented it dynamically to extract the keybox ...

Check out our new blog post on a research-driven look at software-only DRM. Explore how the Qiling emulation framework can be used to analyze Widevine and how Differential Fault Analysis (DFA) and emulation aid de-obfuscation.

🖨️ Print victory! Team @neodyme.io just hacked the Canon imageCLASS MF654Cdw at #Pwn2Own. They head off to the disclosure room once more to provide the details of their exploit. #P2OIreland

Confirmed! Team @neodyme.io used three bugs to exploit the Amazon Smart plug. In doing so, they earn themselves $20,000 and 2 Master of Pwn points. #Pwn2Own

Success! We had a little configuration confusion, but Team Neodyme hopped for joy as their exploit of the Amazon Smart Plug was successful. Their attack went over Bluetooth & WiFI, so they used the RF enclosure. They head off to the disclosure room with details. #Pwn2Own

From Pwn2Own Ireland 2025: NEODYME VS HP YouTube video by Trend Zero Day Initiative

Shout-out to our colleagues at #Pwn2Own in Cork: www.youtube.com/watch?v=e20D...

📢 Confirmed: Team Neodyme used 2 bugs to exploit the Home Assistant Green, but only 1 was unique. They still earn $15,000 and 3 Master of Pwn points. #Pwn2Own

🏠 Well that was quick. Team Neodyme needed only one second to demonstrate their exploit of the Home Automation Green. We know they took their time creating the exploit, but wasted no time showing it off. The head off to the disclosure room to dish the deets. #Pwn2Own

Pwn2Own Ireland 2024: QNAP Qhora-322 In 2024, we competed as team Neodyme in the Pwn2Own Ireland contest, targeting the "SOHO Smashup" category and all available printers. For our entry, we focused on the QNAP QHora-322 router, successfu...

While our colleagues hack live at #Pwn2Own in Cork, take a look at our newly published last year's writeup on our blog: We compromised a QNAP router to take over a networked Canon printer.

Our first confirmation of #Pwn2Own Ireland is in! Team Neodyme used a stack based buffer overflow to exploit the HP DeskJet 2855e. They earn $20,000 and 2 Master of Pwn points. #P2OIreland

Heading to #hack_lu? 🔐
Our colleague Felipe will discuss how partial emulation and DFA can be used to study a legacy version of Widevine L3, Google's software-based DRM.

Lenovo DCC: Part 1 - A simple ACL Exploit The Lenovo Display Control Center (DCC), widely deployed in Windows enterprise environments, contained a critical local privilege escalation vulnerability enabling unauthorized elevation to administra...

⚡️ Lenovo DCC contained an easy-to-exploit LPE: a weak ACL bug → local privilege escalation → full admin 🖥️👨‍💻
We break it down with reverse engineering, process tracing, & two exploit strategies. Read Part 1 of our deep dive: 👉 neodyme.io/de/blog/leno...

Building Our Own Post-Quantum FIDO Token We have built our own FIDO2 token based on post-quantum crypto. Here is how.

▶️ We built a proof-of-concept post-quantum FIDO authenticator. It's phishing- AND quantum-resistant.
✅️ Bonus: it even outperforms Google's prototype. 👀

☀️ Teamwork doesn't just happen at the desk. This week, our crew is in Mallorca, building ideas, strengthening bonds, and enjoying some well-deserved sunshine together. 🌴

Great collaboration comes from trust, connection, and a shared good vibe ✨

Back from @blackhatevents.bsky.social & @defcon.bsky.social! 🎉
Our colleagues delivered insightful trainings on crypto hacking and binary exploitation and got amazing feedback from the crowd 🙌
Missed it? We offer tailored security trainings for companies too. Just reach out.

We reported a vulnerability in Parallels Client via the ZDI last year.
🔥 The issue (CVE-2025-6812) - now fixed: A privileged service searched for an OpenSSL config file in an unsecured location, enabling LPE.

Your router might be a security nightmare: Tales from Pwn2Own Toronto 2022 Three years ago, Neodyme took aim the "SOHO Smashup" category at Pwn2Own Toronto 2022, targeting a Netgear RAX30 router and an HP M479fdw printer. We successfully gained remote code execution on both ...

🏆 Throwback to #Pwn2Own Toronto 2022: "Routers are just Linux boxes with antennas." So we treated one like it. At #Pwn2Own 2022, we turned a Netgear RAX30 into a stepping stone for a full LAN pivot. Story: neodyme.io/en/blog/pwn2...

Riverguard: Mutation Rules for Finding Vulnerabilities Riverguard, the first line of defense for all Solana contracts

HTML to PDF Renderer: A tale of local file access and shellcode execution In a recent engagement, we found an HTML to PDF converter API endpoint that allowed us to list local directories and files on a remote server. One of the PDF files we created, revealed that the conver...

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.
