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.

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.

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 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.

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 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.

A firmware flaw in Coinkite’s Coldcard hardware wallet has been linked to the theft of nearly 600 bitcoin, worth roughly $38 million so far. The incident is forcing Bitcoin investors to reconsider the trade-offs between self-custody, professional custodians and spot Bitcoin ETFs.

A flaw in Coldcard firmware key generation enabled an attacker to drain roughly 594 bitcoin, worth about $38 million, from around 500 single-signature wallets. Coinkite has warned users who created seeds on certain Mk3 devices, while early analysis suggests Mk4, Q and Mk5 devices are not affected so far.
