The original content is primarily a comment section from a blog post on schneier.com. While there isn't a central article, the comments discuss two main topics: ### Bypassing On-Camera Age Verification Several comments address the ineffectiveness and potential ulterior motives behind on-camera age verification checks. One commenter, K.S., suggests that these checks are primarily intended to de-anonymize users and enable governments to restrict access to online platforms. The ease with which these checks can be bypassed raises questions about their true purpose. ### Hard Drive Firmware Hacking A separate discussion thread, initiated by "sweet tasty brain drippings," focuses on the reverse engineering of hard drive firmware. The commenter links to a [Hackaday article](https://hackaday.com/2026/05/15/hacking-hard-drive-firmware/) detailing efforts to modify hard drive firmware for unconventional purposes, such as exploiting **Xbox 360s**. The analysis reveals the existence of backdoor vendor commands and connections to diagnostic RS-232 ports on some drives. Firmware dumps obtained using a **PC-3000** data recovery tool provided valuable insights. The commenter also mentions that accessing the firmware via **JTAG** is another avenue for exploration. **Clive Robinson** adds a technical perspective, noting the significant compute power within hard drive microcontrollers, sometimes exceeding that of the motherboard CPU. He describes encountering multiple **ARM** CPUs within a single microcontroller, along with complex, potentially deliberately obfuscated code. Robinson advises caution when dealing with hard drive firmware due to the complexity and potential for unexpected behavior. ### Zero-Knowledge Proofs Clive Robinson also references a paper on Zero-Knowledge Proofs: [https://eprint.iacr.org/2025/1296](https://eprint.iacr.org/2025/1296) > **Gödel in Cryptography: Effectively Zero-Knowledge Proofs for NP with No Interaction, No Setup, and Perfect Soundness** > Rahul Ilango, Massachusetts Institute of Technology. > "*A zero-knowledge proof demonstrates that a fact (like that a Sudoku puzzle has a solution) is true while, counterintuitively, revealing nothing else (like what the solution actually is). This remarkable guarantee is extremely useful in cryptographic applications, but it comes at a cost. A classical impossibility result by Goldreich and Oren [J. Cryptol. ’94] shows that zero-knowledge proofs must necessarily sacrifice basic properties of traditional mathematical proofs — namely perfect soundness (that no proof of a false statement exists) and non-interactivity (that a proof can be transmitted in a single message).* > > *Contrary to this impossibility, we show that zero-knowledge with perfect soundness and no interaction is effectively possible. We do so by defining and constructing a powerful new relaxation of zero-knowledge. Intuitively, while the classical zero-knowledge definition requires that an object called a simulator actually exists, our new definition only requires that one cannot rule out that a simulator exists (in a particular logical sense). Using this, we show that **every falsifiable security property of (classical) zero-knowledge can be achieved with no interaction, no setup, and perfect soundness.** This enables us to remove interaction and setup from (classical) zero-knowledge in essentially all of its applications in the literature, at the relatively mild cost that such applications now have security that is “game-based” instead of “simulation-based.”*" Robinson highlights the potential implications of this research for age verification and other authoritative applications.
