Bluetooth is one of the most widely deployed wireless technologies, yet most discussions barely scratch the surface of how it actually works. Underneath the simple “Pair” button is a layered networking stack that includes HCI, L2CAP, SDP, RFCOMM, ATT, GATT, SMP, and several application profiles, all working together to establish secure communication between devices. Like any complex networking protocol, Bluetooth has also had its share of implementation flaws, from early attacks like Bluesnarfing and Bluebugging to more recent vulnerabilities such as BlueBorne, KNOB, BIAS, BLESA, and SweynTooth. Here’s a comprehensive guide to everything about Bluetooth

A serious firmware flaw in COLDCARD hardware wallets has shaken the Bitcoin community after researchers linked it to large-scale wallet thefts. The issue affects seed generation, where some firmware versions produced recovery phrases with significantly lower entropy than intended. That makes the 24-word seed phrase far more predictable, allowing attackers to brute-force private keys in cases where users relied solely on the generated seed. Reports indicate hundreds of wallets have already been drained, with approximately 594 BTC stolen.

PwC is facing scrutiny after several AI-assisted reports were found to contain fabricated citations and references to sources that either did not exist or could not be verified. Following an investigation by the Financial Times and GPTZero, the firm withdrew or updated the affected reports

Many people assume that an AI “Share” link is effectively private unless they send it to someone. That’s not how the web works. Recently, users discovered that searches like site:claude.ai/share and site:claude.ai/public/artifacts returned publicly shared Claude conversations through search engines. Some indexed pages reportedly contained resumes, company discussions, code, and other sensitive information. Google began removing many results, but the incident highlights an important privacy lesson: once a conversation is published as a public webpage, it can become discoverable

India has directed GitHub to disable access to the repositories of Bitchat, Jack Dorsey’s decentralized Bluetooth mesh messaging application, under Section 79(3)(b) of the Information Technology Act and the IT Rules, 2021. According to the official notice issued by the Indian Cyber Crime Coordination Centre (I4C), authorities argue that Bitchat’s decentralized architecture, lack of mandatory user registration, absence of centralized logging, and ability to operate without internet connectivity make lawful interception and criminal investigations significantly more difficult.

A newly disclosed vulnerability chain dubbed wp2shell affects WordPress Core, not a third-party plugin. The disclosure has prompted emergency security updates and includes publicly available PoC, IoCs, and detection guidance for defenders

Discord has quietly begun testing Incode as a new age verification provider, replacing its previous vendor for some users. The company says face scans are processed on-device where possible, IDs and selfies are deleted after age confirmation, and Discord only receives an age result, not your identity. But the move still raises important privacy questions around biometric verification, third-party trust, and the growing trend of mandatory age checks online, especially after the massive Persona breach linked to Discord user data back in 2025

Ach, ein Böllerverbot … so richtig mit effektiver Durchsetzung, das wär’ mal was. Ich ahne: die Verantwortlichen “… beobachten aufmerksam, was der Rest der Welt so macht …”

Also – rechtzeitig Feiertagslektüre ausleihen!

Und im Rest der Stadt so?

Na gut, ist jetzt nicht SO ein Wilkdkost-Thema. Aber da starteten bis zur Einstellung die Mundraub-Touren, und wäre wohl auch ein geeigneter Ort/Treffpunkt für Überlegungen zu einem Neustart.

Vielleicht schon bald?
