The Great Hackening of 2026

— Coldcard suffered a critical random number generator (RNG) bug where the firmware's safety check was "defined" but not executed, severely degrading entropy from cosmic-scale randomness to near-pseudorandom levels, potentially allowing key collisions and fund theft.

— Liquid Network was exploited for 4,200 BTC via a cache verification bug in confidential transactions; an attacker created fake proofs, inflated the LBTC supply, and extracted 4,200 BTC before returning 3,600 voluntarily (gray-hat).

— Multiple Lightning implementations (Core Lightning, LND, Eclair) disclosed buffer overflow and denial-of-service vulnerabilities that could crash nodes via malicious messages or flooded gossip protocols.

— BitBox, Sparrow Wallet, Trezor, and Ledger all disclosed security vulnerabilities and data breaches; none exploited in the wild but all require immediate firmware/software updates.

— AI-powered exploitation has inverted attack economics: frontier models can now discover and exploit bugs with minimal human skill or time cost, making Bitcoin and Layer 2 systems attractive targets due to irreversible payouts.

— Update all hardware wallets (BitBox, Trezor), Lightning nodes (CLN, LND, Eclair), and software wallets (Sparrow) immediately; move funds off Coldcard Mark 3 and Mark 4 devices without delay, as the RNG bug likely enabled real key collisions already exploited by attackers.

— Implement physical security (visible security cameras, dog, gun/weapon training) and operational security (use PO box for hardware deliveries, never click email links, forward security newsletters to an AI agent for daily threat monitoring) to reduce targeting and phishing risk from leaked personal data.

— Set up automated monitoring of all holdings using AI agents (e.g., PPQ.ai) to track firmware updates, security disclosures, and vulnerability reports across the entire personal security stack in real-time.
