Israel has now killed more than 130 medics in Lebanon in less than 3 months. And the world watches in silence.

Beste @vrtnws, Als u uw data over de "Foto van Vlaanderen" echt wil delen, dan zet u ze op een website in een csv, xlsx, pdf, word, sav, en nog een paar andere formaten. Maar ik kom niet volgende dinsdag om 14h met mijn pc naar Brussel met mijn SPSS licentie. Dank u voor de parkeerplaats, maar anno 2026 delen we digitaal. mvg Geert

It has been assumed that hantavirus is contagious only if someone is in close contact with someone who’s having symptoms. Some experts now suggest it’s possible it may be more contagious than thought. nbcnews.com/health/health-ne…

Compared to Concord, Suicide Squad or recent slop, Mixtape is a true Millennial unc-core story to enjoy. It's not so original, but the nu-con moaning is misplaced because: 1) ultimately it's a story about growing up and freedom 2) artistically it shows knowledge in the niche it picks

Volvo organiseert een paar feestjes, en achter de schermen is er misschien nog een jaartje, of allezja 2 jaartjes, politiek en zo. Bij Nike net hetzelfde. Nadien zal het zijn van: ah ja maar dat was de vorige politieke generatie. Het geld is op, het gaat hier niet meer.
Nu een index erbij is de dood van veel private jobs. Volvo en Nike staan op sluiten. De chemie én de pharma staan op instorten. Maar men blijft honderduizenden mensen uitkeringen uitbetalen waar ze geen recht op hebben, en doen alsof de rijken alles gaan betalen. Fantasialand.

Ah if that is true it explains a lot. After the weekend we get a lot of left over CISO bullshit why our headers were not right...

Hacking the #EU #AgeVerification app in under 2 minutes. During setup, the app asks you to create a PIN. After entry, the app *encrypts* it and saves it in the shared_prefs directory. 1. It shouldn't be encrypted at all - that's a really poor design. 2. It's not cryptographically tied to the vault which contains the identity data. So, an attacker can simply remove the PinEnc/PinIV values from the shared_prefs file and restart the app. After choosing a different PIN, the app presents credentials created under the old profile and let's the attacker present them as valid. Other issues: 1. Rate limiting is an incrementing number in the same config file. Just reset it to 0 and keep trying. 2. "UseBiometricAuth" is a boolean, also in the same file. Set it to false and it just skips that step. Seriously @vonderleyen - this product will be the catalyst for an enormous breach at some point. It's just a matter of time.
.@vonderleyen "The European #AgeVerification app is technically ready. It respects the highest privacy standards in the world. It's open-source, so anyone can check the code..." I did. It didn't take long to find what looks like a serious #privacy issue. The app goes to great lengths to protect the AV data AFTER collection (is_over_18: true is AES-GCM'd); it does so pretty well. But, the source image used to collect that data is written to disk without encryption and not deleted correctly. For NFC biometric data: It pulls DG2 and writes a lossless PNG to the filesystem. It's only deleted on success. If it fails for any reason (user clicks back, scan fails & retries, app crashes etc), the full biometric image remains on the device in cache. This is protected with CE keys at the Android level, but the app makes no attempt to encrypt/protect them. For selfie pictures: Different scenario. These images are written to external storage in lossless PNG format, but they're never deleted. Not a cache... long-term storage. These are protected with DE keys at the Android level, but again, the app makes no attempt to encrypt/protect them. This is akin to taking a picture of your passport/government ID using the camera app and keeping it just in case. You can encrypt data taken from it until you're blue in the face... leaving the original image on disk is crazy & unnecessary. From a #GDPR standpoint: Biometric data collected is special category data. If there's no lawful basis to retain it after processing, that's potentially a material breach. youtube.com/watch?v=4VRRriyD…

If you try and copy and paste something from @coursera, they hide a prompt injection in your clipboard. It tells the AI agent to click on an invisible button called "AiHoneypot" that presumably then bans you from the course.
