Oh Wiz
To teach a lesson, After Wiz rushed to buy php2shell domain and use its marketing machine to steal the spotlight, I spotted "phpbleed" in a recent Calif tweet and bought phpbleed.com before wiz could pull the same stunt again. A big budget can buy a domain. It shouldn't buy someone else's research credit. If you have contacts at CISA or in the press, do the right thing: make sure the researchers who actually did the work get the recognition they deserve. Hack the planet. Credit the researchers.

Bought two Ledgers from the Ledger Authorized Store on Amazon Sweden and opened them. Both clean. No antennas, no cellular module, no extra wires. What bad luck :P In the tampered ones, the chip was genuine. The attackers didn’t hack it, they just read the seed from the screen while you set it up. Crazy!

En 2026 se han generado casi el 40% de todos los CVE del Kernel de Linux desde 1997. Tras la IA, ¿qué provoca más CVEs del kernel? Según Greg Kroah-Hartman, mantenedor del núcleo y voz relevante en la seguridad, una línea es responsable de la mitad de los CVE desde 2024. Hilo¬

Ledger Nano X received from @0xJohannes_ (who bought it from MediaMarkt in Germany) confirmed bugged (he sent another one to @Ledger). This is not news and action has already been taken, the next question will be to understand how this ended in Germany...

Ledger Flex sold at Singapore Airport confirmed to contain a spy implant! @BenYorke found suspicious marks on his @Ledger and sent it to me rather than using it, that was probably the best decision here. youtube.com/watch?v=Nf4FEFlg… xitter.cf/BenYorke/status/210908…
I have a $300 @Ledger Flex that I bought from the Singapore airport in summer (Metapod, should be fine?) I never plugged it in but it looks like theres some scratches on the casing, an indication of potential tampering? Anyways theres no way i can trust it (or Ledger) now

The @hackinhire team spent last Wednesday with future HR people in Lund. The ones who’ll be screening security candidates in a few years. Good place to start the conversation.

Replying to @IKEA
@IKEA makes the most enjoyable hackable products out there. My home has many that have been extended (documented github.com/danielcuthbert/ho…) but they have a new one ikea.com/lt/en/p/kortlinje-a… and some Dutch hackers have started playing forum.revspace.nl/t/ikea-kor…

This is escalating quickly 😳
PSA the ledger incident isn't limited to Asia This is a device purchased in store from an official reseller in Europe (a legitimate device doesn't have any of these cables as can be seen in picture 2) This even seems to be an old version of the 'spy implant' even though the device was purchased a couple of weeks ago. The newer versions usually hide the implant by the screen so it's easier to miss What's interesting is that this compromised ledger never transfered funds to an exploiter. Either the device didn't work or they were waiting for a more widespread usage of the comprised devices? If you own a ledger that didn't directly come from the ledger online store make sure to not just rely on the software genuinely check by ledger but to actually open up the ledger yourself to make sure its original, again there are reported cases in Asia, south America and now Europe as well. @MagicalTux made some useful videos on how to open the ledger and what to look for.

Si convertir un ESP32 en SDR era un flipe, llega ESTO:
Turned a WiFi 7 router into a 320Msps SDR. Custom firmware on its MediaTek MT7996 streams raw 14-bit IQ from 2.4/5/6GHz over 10GbE without dropping samples. It's not a snapshot mode, the waterfall is just one thing reading the stream. github.com/h0m3us3r/w1700k-s…

First time raising. If you invest in cyber or European B2B and you’ll be in Helsinki, my DMs are open.
Hack in Hire will be at #Slush 2026 in Helsinki, 18 and 19 November. We're raising our first funding round. We got here bootstrapping, working with clients like ING Hubs Spain, Zynap and Zerolynx, because we wanted to test the model before asking anyone to bet on it. It works, and clients are renewing. Now it needs to move faster. We'll be showing the product and meeting investors focused on technology, cybersecurity, hiring or European B2B. If that's you, we'd like to talk before Helsinki, not just there. This one happens thanks to Minc. Being part of the Malmö startup community has put us in rooms we wouldn't have reached alone.

Do yourself a favour and read the terms 👇🏼
Replying to @claudeai
The terms for this sucks, and you agree to them by just applying. - §2.4 Anthropic "may develop similar or competitive technology" - §2.4 permits reuse, for any purpose, of general ideas, know-how and techniques remembered by personnel looking at your data - §D.4 prohibits accessing their services to build competing products or services - §F.1 allows them to retain and perform safety reviews, superseding ZDR (whats the point of ZDR then?) and it could get worse later! - §6 permits changes to the addendum at any time without notice or liability @jason you advising your start ups to apply for this?
