  • Coldcard Bitcoin Hack Update: 64 BTC Moves Through Wasabi Mixer While 1,159 BTC Stays Dormant

    Coldcard Bitcoin Hack Update: 64 BTC Moves Through Wasabi Mixer While 1,159 BTC Stays Dormant

    Investigators tracking the Coldcard wallet vulnerability have detected fresh movement of stolen Bitcoin through a privacy mixer. While a separate attacker has begun obscuring roughly 64 BTC via Wasabi Wallet, the largest known theft cluster remains untouched.

    1,159 BTC Still Unmoved

    Galaxy Research linked the biggest theft to approximately 1,159 BTC held across seven attacker-controlled addresses. The attacker consolidated the funds within about 41 minutes of the exploit and has not sent them to exchanges, mixers, or other identifiable services since then.

    Bitcoin’s protocol cannot freeze flagged addresses, so the funds remain spendable. However, converting such a large balance could expose the attacker. Exchanges, law enforcement agencies, and blockchain analytics firms are reportedly tracking around 600 addresses connected to the broader exploit.

    Separate Attacker Moves 64 BTC Through CoinJoin

    Analysts identified another attacker attempting to obscure approximately 64 BTC using Wasabi Wallet’s CoinJoin feature. About 10 BTC entered an initial mixing transaction, while roughly 54 BTC returned as change. The remaining Bitcoin later moved into outputs of about 7 BTC each, apparently for further mixing.

    CoinJoin combines multiple inputs and outputs, making direct links harder to establish. Still, timing patterns, output sizes, later consolidations, and exchange deposits can reveal useful clues for investigators.

    Exploit Scale and Affected Seed Phrases

    Galaxy Research estimates confirmed losses near 1,596 BTC. A suspected additional attack wave could raise the total to about 2,055 BTC, while other researchers have placed losses above 1,800 BTC.

    The vulnerability affected seed phrases created with weakened random-number generation. Firmware updates prevent new vulnerable seeds, but they cannot repair seed phrases already exposed. Affected users must create a new wallet seed and move their Bitcoin. Coldcard also destroyed remaining vulnerable inventory and urged users to generate fresh seeds.

    South Korean Users Avoided Major Losses

    South Korea’s Bitcoin community reported virtually no direct losses despite many experienced holders using Coldcard devices. Analyst Koji Higashi linked that outcome to local self-custody practices: community leaders had promoted independent entropy generation instead of relying solely on one hardware wallet manufacturer.

    Local guides described 128 coin flips for 12-word seeds and 256 coin flips for 24-word seeds. Some users converted binary results using hardware calculators rather than phones, adding another layer of protection against compromised random-number generators.

    Key Takeaways

    • The 1,159 BTC connected to the largest Coldcard attacker remains unmoved since consolidation.
    • A separate attacker has routed about 64 BTC through Wasabi Wallet CoinJoin transactions.
    • Confirmed losses stand at roughly 1,596 BTC, with possible totals exceeding 2,000 BTC.
    • Firmware updates cannot secure already exposed seed phrases; affected users must migrate to new wallets.
    • Independent entropy generation helped many Korean users avoid direct losses.

    Analyst Insights

    CoinSwitch Markets Desk noted that BTC remained range-bound near $65,000 despite a risk-on tone across global markets. The S&P 500 extended its rally past 7,793 points, and gold jumped 2.8% to a six-week high near $4,213 an ounce. A sustained Bitcoin recovery may need stronger ETF inflows and softer Treasury yields.

    Prateek Gupta, Head of Business at Mudrex, said Bitcoin stayed inside its broad $64,000–$64,700 band. He noted that the S&P 500 closed above Bitcoin on relative performance for the first time since 2012. Long-term holders sold over 11,500 BTC this week.

    Riya Sehgal, Research Analyst at Delta Exchange, said gold climbed to a seven-week high near $4,286 an ounce. Lower Treasury yields and renewed safe-haven demand drove the move. Bitcoin consolidated near $64,500, holding a constructive structure while staying above $64,000.

    Coldcard Exploit Losses Widen Past $130 Million

    Galaxy Research now estimates at least 15 separate attackers are exploiting the Coldcard firmware flaw. Confirmed and suspected losses have climbed to roughly 2,055 BTC across more than 7,700 wallet addresses. Coinkite founder Rodolfo Novak apologized publicly and pledged support for affected users.

The streak follows an eight-week outflow stretch that had tested confidence in the broader ETF adoption story.

    Hashdex to Close Its Smallest Bitcoin ETF

    Hashdex confirmed it will close and liquidate the Hashdex Bitcoin ETF, trading under the DEFI ticker on NYSE Arca.

    Bernstein warned that fading odds for CLARITY Act passage could pressure crypto prices as the Senate enters recess. Analysts said a failed vote may trigger an immediate negative market reaction.

Policy uncertainty remains a key variable for institutional positioning heading into September trading sessions.

    Metaplanet Raises $137 Million for Its Bitcoin Treasury

    Japan’s Metaplanet confirmed a $137 million capital raise through third-party allotment to expand its Bitcoin holdings.

Corporate accumulation in Asia continues to grow despite recent volatility across Bitcoin’s broader price structure.

    Coinbase Signals Doubts Over Senate Crypto Bill

    Coinbase indicated it may withdraw backing for the Senate’s crypto market structure bill over unresolved provisions. The exchange’s hesitation adds fresh uncertainty to an already fragile legislative timeline this month.
