NEW: $STRC up 3% on the day, following the news that MSTR has increased their cash position to $4 billion.

COLDCARD BUG MAY HAVE BEEN CAUSED BY A COMPILER WORKAROUND A new technical analysis by Core-Lightning dev ddustin suggests the 2021 COLDCARD vulnerability may have started while a developer was trying to connect three layers of the firmware: the wallet’s Python code, MicroPython’s C code, and the STM32 hardware random number generator. The custom code appears to have conflicted with MicroPython’s existing implementation, likely triggering a compiler error. The evidence suggests the developer then disabled the hardware RNG by setting MICROPY_HW_ENABLE_RNG to 0, allowing the firmware to compile. That change had an unintended consequence. When users created new wallets, the firmware no longer used the hardware random number generator. Instead, it fell back to MicroPython’s much weaker Yasmarang software random number generator. The commit message left by the dev was just the word “runs.” The analysis argues this is a reminder that developers should never ship security-critical code they don’t fully understand, especially when it protects billions of dollars in Bitcoin.

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.

NEW: Michael Saylor confirms that the main impetus for the Bitcoin Security Consortium was to help address institutional investor fears over the quantum threat.

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.

FRATERNAL ORDER OF POLICE BACKS REVISED CLARITY ACT The Fraternal Order of Police, representing more than 382,000 law enforcement officers, has formally endorsed the revised CLARITY Act after reviewing its updated text. The group says new clarifying language preserves law enforcement’s ability to investigate digital asset-related crime while addressing concerns it previously raised. It also praised provisions expanding anti-money laundering tools, improving information sharing, strengthening fraud prevention, supporting state and local enforcement, and clarifying that protections for non-custodial software developers do not shield those who intentionally facilitate criminal activity. The FOP says its initial concerns have been satisfactorily addressed and is urging Congress to pass the amended bill.

🇮🇳 INDIA ORDERS GITHUB TO REMOVE BITCHAT REPOSITORIES India’s Ministry of Home Affairs has ordered GitHub to remove or disable access to the BitChat repositories within three hours under Section 79(3)(b) of the Information Technology Act and the 2021 IT Rules. The order targets the BitChat repository, the Android repository, and Android releases. Authorities claim the decentralized Bluetooth mesh messaging app enables anonymous, serverless communication that hinders lawful interception and could be misused to evade surveillance, coordinate unlawful activities, spread misinformation, or operate during internet shutdowns.
