NUNCHUK ON COLDCARD VULNERABILITY

Some Nunchuk platform keys were generated with a Coldcard Mk4, but the company says those keys are never used directly.

Instead, it derives separate keys through custom logic, making them less susceptible to lookup-table attacks based on compromised Coldcard seeds.

Nunchuk adds that, given enough time, it assumes attackers could eventually include those derived keys as well.

COINKITE WARNS COLDCARD MK3 USERS OF POTENTIAL FUND RISK

Coinkite is urging anyone who generated a seed on a COLDCARD Mk3 running firmware version 4.0.1 (released March 2021) or later to treat their funds as potentially at risk.

The company says the vulnerability affects all Mk3 firmware through version 5.0.3, the final release for the device.

Based on its initial analysis, Coinkite says Mk4, Q, and Mk5 devices are not affected.

Users who protected their Mk3 wallet with a BIP-39 passphrase face minimal risk, according to the company.

Coinkite recommends migrating funds to a newly generated seed on an unaffected device, or, if necessary, using a strong BIP-39 passphrase or a dice-only seed as an interim measure.

The company says its investigation is ongoing and a full technical review will follow.

ANTHROPIC: AI DISCOVERS NEW CRYPTOGRAPHY ATTACKS, WEAKENS POST-QUANTUM CANDIDATE

Anthropic says its Claude Mythos Preview AI discovered two new cryptographic attacks, including one that significantly weakens the HAWK post-quantum digital signature candidate and another that speeds up attacks on a reduced-round version of AES by 200-800x.

The company stressed neither finding affects production systems or breaks the full AES standard.

Instead, the research demonstrates AI’s growing ability to uncover mathematical flaws in cryptographic algorithms that have withstood years of expert review.

Anthropic says Claude developed the HAWK attack in roughly 60 hours and estimates each breakthrough cost about $100,000 in API compute.

NEW NEWSLETTER JUST DROPPED

Despite Bitcoin trading around the same price it reached at the peak of the 2021 bull market, the network has racked up so many victories over the past five years that it is difficult to keep track.

The launch of spot Bitcoin ETFs, an explosion in Layer 2 development, a wave of corporate adoption, Bitcoin-backed mortgages, and even the creation of a Strategic Bitcoin Reserve were once considered distant dreams. Today, they are reality.

Yet with nearly every major milestone has come a chorus of critics arguing that Bitcoin is somehow losing its way.

The same debate has now emerged around the newly formed Bitcoin Security Consortium, where some of the biggest names in institutional Bitcoin have pledged $15 million to support Bitcoin development and long-term security.

Is this institutions giving back to the network that made their success possible, or is it the first step toward covertly gaining influence over Bitcoin's future? We investigate below.
