Coldcard

Whitehat operators have moved 52.37 BTC connected to the July Coldcard wallet exploit into an address tied to a newly formed recovery trust. The transfer is part of the continuing effort to separate recovered funds from malicious activity after estimated losses of more than $100 million.

Six Bitcoin wallets last active between 2011 and 2014 moved 553.59 BTC worth about $40 million from Aug. 16 through Aug. 26. The transfers drew attention because most of the coins did not move to known exchanges, while broader dormant Bitcoin activity has slowed to its lowest level since 2022.

Coinkite has released new Coldcard firmware after a randomness flaw enabled attackers to steal more than $114 million in bitcoin. The company says AI-assisted review found additional issues, but users with affected seeds still need to create new wallets and migrate funds.

Attackers have drained nearly $114 million in bitcoin from more than 709 addresses after exploiting a Coldcard firmware flaw that weakened wallet seed randomness. The incident is forcing the self-custody community to confront uncomfortable questions about verification, reputation, and how security review is encouraged or discouraged.

Russian retailers reported a sharp increase in hardware crypto wallet sales as new rules for digital assets move closer. The surge highlights growing interest in self-custody, even as legal limits and device-security risks remain firmly in place.

Bitcoin is approaching the $66,000 resistance area after rising 3% over the past 7 days, while spot ETF demand has strengthened sharply. Technical traders are watching whether BTC can confirm a bullish breakout toward $75,000 or fail again and risk a retreat toward $60,000.

Large Bitcoin holders have accumulated over 20,000 BTC since July 29, while U.S. spot Bitcoin ETFs attracted $754.69 million this week. The buying has not yet delivered a decisive breakout, with technical traders watching for a close above $65,000.

A bitcoin wallet inactive since 2011 moved nearly 50 BTC worth about $3.2 million to a SegWit address with prior links to FalconX-labeled deposits. The coins remained at the receiving address as of Friday morning, leaving the holder’s intent unclear.

A volunteer group of Bitcoin developers using AI tools has identified thousands of vulnerabilities across wallets, cryptographic libraries and infrastructure projects. The effort underscores both the defensive promise of AI-assisted security research and the growing risk that attackers can use the same methods.

The Coldcard wallet exploit has intensified debate over the operational risks of bitcoin self-custody after at least 1,816 BTC was drained from more than 5,200 addresses. Analysts say the breach could support demand for spot bitcoin ETFs and regulated custody platforms as some investors reassess how they hold crypto exposure.

A five-year-old Coldcard firmware flaw led to the theft of almost 1,600 BTC from around 7,300 addresses, intensifying debate over bitcoin self-custody. FXCOINZ finds that many affected holders are not abandoning self-custody, but are shifting toward collaborative multisig models designed to reduce single-device risk.

Bitcoin’s mempool transaction count has surged after the Coldcard wallet hack, highlighting a wave of coin movement across wallets and exchanges. BTC remains confined to its recent trading band as market participants weigh policy risk around the Clarity Act and pressure from real Treasury yields.

A bitcoin wallet linked to the Coldcard hacker is receiving small deposits carrying permanent on-chain messages, ranging from pleas for refunds to opportunistic pitches. The activity highlights how Bitcoin’s OP_RETURN function can turn a theft address into a public, immutable message board.

Jim Cramer says he plans to sell all of his bitcoin because of concerns that quantum computing could threaten crypto security within three to four years. Bitcoin has remained resilient near $64,000, with many traders treating the warning as another contrarian signal.

A Bitcoin wallet inactive since 2013 moved 500 BTC worth about $31.3 million on Monday, drawing attention as long-dormant coins began shifting on-chain. The movement comes during a broader security crisis tied to Coldcard hardware wallets, with market participants watching whether old holders are migrating funds out of caution.

Bitcoin recovered in Asian trading, reclaiming the $63,000 level after a Monday dip near $62,250. Major tokens mostly advanced, though ether remained the lone large cryptocurrency still lower over the past seven days.

A solo Bitcoin miner packaged block 960,804 and earned 3.157 BTC, worth about $199,300, in another rare win for independent operators. The milestone arrived as Coldcard wallet concerns, rising BTC exchange reserves, weaker technical signals and fading regulatory momentum weighed on market confidence.

A new wave of bitcoin sweeps tied to Coldcard-generated addresses may have lifted observed losses to about 1,816 BTC, or nearly $114 million, since July 30. Researchers say the latest pending transactions appear to use replace-by-fee, giving alert users a narrow window to outbid the attacker before confirmation.

Bitcoin and ether weakened even as oil prices, Treasury yields and equity futures pointed to a more supportive macro backdrop. Market attention remains fixed on Coldcard-linked wallet sweeps that have drained roughly 1,367 bitcoin from thousands of addresses.

Bitcoin holders are moving funds back to centralized exchanges after a Coldcard hardware wallet vulnerability raised fresh concerns about self custody. On chain data shows smaller transfers and exchange deposits spiking in a pattern that contrasts sharply with the response to FTX’s collapse.

A Coldcard firmware vulnerability tied to weak software-based randomness has been linked to three waves of bitcoin sweeps across thousands of addresses. The latest activity is targeting smaller balances and using more complex onchain collection patterns.

Bitcoin slipped nearly 3% after a Coldcard wallet bug rattled confidence in cold storage security and triggered fresh caution across crypto markets. With spot Bitcoin ETFs seeing a $265 million daily outflow, traders are watching whether BTC can defend $60,000 or risk a deeper move toward $50,000.

Binance founder Changpeng Zhao has urged crypto holders to spread funds across multiple wallets after a major Coldcard hardware wallet exploit. The incident exposed a long-running firmware flaw that allowed an attacker to reconstruct private keys offline and drain bitcoin from affected addresses.

More than 1,000 bitcoin was drained from 1,196 Coldcard wallets in a 41-minute window on July 30 after weak seed generation made private keys computationally searchable. Security researchers warn the episode challenges a core assumption of cold storage: that offline keys are not just unreachable, but effectively unguessable.
