00:02:22 Key listening attack
New acoustic attack steals data from keystrokes with 95% accuracy [BleepingComputer]
A team of researchers from British universities has trained a deep learning model that can steal data from keyboard keystrokes recorded using a microphone with an accuracy of 95%.
When Zoom was used for training the sound classification algorithm, the prediction accuracy dropped to 93%, which is still dangerously high, and a record for that medium.
“Much before AI key listening there was just key listening. And also hidden cameras and tempest attacks. That’s why key scrambling for PINs is so important.” ~ @NVK
00:15:03 Libbitcoin Bitcoin Explorer Vulnerability CVE-2023-39910
“If you generated a wallet using Libbitcoin’s Bitcoin Explorer, including as described in the appendix to Mastering Bitcoin, your funds are at risk (or already stolen).” [David A. Harding / Full details]
Details:
Milk Sad discovered a cryptographic weakness in the widely utilized Libbitcoin Explorer (bx) cryptocurrency wallet tool while following up on mysterious wallet thefts.
The bx seed subcommand for generation of new wallet private key entropy is flawed and produces insecure output.
On Libbitcoin Explorer 3.x versions, bx seed uses the Mersenne Twister pseudorandom number generator (PRNG) initialized with 32 bits of system time.
Bad actors have discovered this flaw and are actively exploiting it to steal funds from affected wallets on multiple blockchains.
There is reason to believe some Libbitcoin Explorer versions before 3.0.0 also produce weak bx seed output in some system environments.
Think of this as securing your online bank account with a password manager that creates a long random password, but it often creates the same passwords for every user. Malicious people have figured this out and drained funds on any account they can find.

Decompositions that produce change outputs are now rarely chosen.
Adjustments to the anonymity score calculator reduces the amount of coinjoining required before coins are considered private

01:59:36 Orage: A new lightning network server implementation by Civkit [Announcement]
Focus on high-availability, modularity and security
Built on the Lightning Development Kit (#LDK), Orage aims to provide the necessary tools, simplicity, and infrastructure to seamlessly integrate both individual users and enterprises into the ecosystem
Utilizing the LDK, Orage offers built-in features such as custom scripts. This will pave the way for greater flexibility in the types of applications that can be built on the #LightningNetwork.
The goal is to stimulate the development of more ‘Lightning-aware’ applications by integrating custom scripts, Discreet Log Contracts (DLCs), and Taproot.

Bitcoin Optech Newsletter
02:03:52 Highlights from recent Bitcoin Optech Newsletters
LN specification clean up proposed:
Rusty Russell posted to the Lightning-Dev mailing list a link to a PR where he proposes to remove some features that are no longer supported by modern LN implementations and to assume other features will always be supported.
Simplified LN closing protocol:
Rusty Russell posted to the Lightning-Dev mailing list a proposal that simplifies the process of two LN nodes mutually closing a channel they share. With the new closing protocol, one of the nodes tells its peer that it wants to close the channel and indicates the amount of transaction fee it will pay.
That closing initiator will be responsible for the entire fee, although both outputs of a typical mutual close transaction will be immediately spendable so either party will be able to use CPFP fee bumping in the normal case.
The new protocol is also compatible with exchanging information for MuSig2-based scriptless multisignatures, which are part of in-development upgrades to LN that will increase privacy and lower onchain fee costs.
LN Summit notes:
Ropics discussed included: Reliable transaction confirmation, Taproot and MuSig2 channels, Updated channel announcements, PTLCs and redundant overpayment, Channel jamming mitigation proposals, Simplified commitments, The specification process
Safety of blind MuSig2 signing:
Tom Trevethan posted to the Bitcoin-Dev mailing list to request a review of a cryptographic protocol planned as part of a statechains deployment.
The goal was to deploy a service that would use its private key to create a MuSig2 partial signature without gaining any knowledge about what it was signing or how its partial signature was used.
The blind signer would simply report how many signatures it had created with a particular key.
