The implant watched the screen during setup, captured the 24-word recovery phrase and sent it over LTE, without touching the Secure Element. Tether froze about $10 million USDT. Reports from Changi Airport and MediaMarkt stores remain unconfirmed.

Ethresear.ch post porting Tornado Cash to Flock, a post-quantum binary-field SNARK, proving a depth-32 SHA-256 withdrawal in about 19.5 ms (203.6 KiB proof), with recursive aggregation at about 0.68 s per withdrawal. It also proposes a ZIP 2005-inspired recovery protocol: wallets derive note secrets from a seed, the pool freezes on a discrete-log break, and users withdraw through a post-quantum verifier. Security is argued under an epoch assumption, with Grover-bounded pre-image attacks.

Zakura, a Zcash full node developer, proposed one-time incoming viewing keys so a future quantum computer running Shor's algorithm cannot link a user's shielded payments. The target is NEAR Intents swaps, which post a shielded refund address on a public chain. The fix needs no network upgrade and uses private information retrieval for seed restores. Wallets such as Vizor can add it within weeks.

Zakura, a newer version of the Zcash node software, plans to give each ZEC swap through NEAR Intents its own viewing key. Today a refund address posted on NEAR's public chain shares one viewing key with the whole account, so a future quantum attacker running Shor's algorithm could link the account's full payment history. Spending keys stay with the user, and private information retrieval lets wallets find refunds without revealing which addresses they check. Wallets such as Vizor could ship it within weeks.

CoinDesk reports Google's Science paper showing its Willow chip prepares "magic states" with about 40x fewer errors (about 99.99% fidelity, but only about 8% of attempts survive post-selection) using a method called cultivation. It explains why this lowers one hardware bottleneck for a Shor's-algorithm attack on Bitcoin's ECDSA keys, but does not make an attack 40x cheaper. It also separates coins with permanently exposed public keys (early Satoshi-era outputs, which an offline attacker can target) from hash-hidden keys, where the attacker must race the spend. The article cites Google's March estimate of under 500,000 physical qubits and about 500,000 reliable magic states per second for a roughly nine-minute attack.

Rekt write-up on LTE-equipped hardware implants found in Ledger Nano X and Flex wallets sold through resellers such as CryptoBilis and MediaMarkt. The implants read the recovery phrase off the screen during setup and exfiltrate it over an eSIM/LTE modem, so Ledger's Genuine Check and Secure Element never detect them. It covers the teardown timeline (Joe Grand, Mark Karpelès, a Japan-based researcher), the 47-minute multi-chain drain (Bitquery estimates about $102M across 324 wallets, unverified by Ledger), the laundering path via USDD, THORChain, Tornado Cash and Zcash, the CryptoBilis ownership change, and the failure of "authorized reseller" trust.

Galaxy Research's weekly brief leads with the roughly $91M theft from Ledger devices sold via the reseller CryptoBilis. A hidden hardware implant read the 24-word recovery phrase off the screen during setup and sent it over LTE through an eSIM, leaving the Secure Element untouched so Genuine Check still passed. Galaxy's onchain tally covers 474 victim addresses, 88% of the value moved in one hour on Oct. 9, and about $56.6M was still parked as of Oct. 15, with Tornado Cash use and a $10M Tether freeze. It places the theft alongside the Coldcard weak-seed, Liquid peg-out and Bitget compromises, and ends with buyer and custody advice. The Papertrade and OCC debanking sections are unrelated to security.

Galaxy Research newsletter piece on the roughly $91M theft from buyers of Ledger hardware wallets sold by the reseller CryptoBilis. A hidden component reads the 24-word recovery phrase off the screen during setup and sends it over LTE via an eSIM. The Secure Element and Genuine Check are untouched, so the check passes on tampered units. It traces the drain across 474 victim addresses on Bitcoin, Ethereum and TRON, including 88% of the value moving in one hour on Oct. 9, and the laundering and freezes (Tornado Cash, Tether). It also places the incident among the quarter's other custody and infrastructure failures (Coldcard weak seeds, Liquid, Bitget) and gives buying and operational guidance.

The Defiant reports that Mark Karpelès found hardware implants in Ledger devices bought from two more resellers. Ledger says its inspections of German stock found no tampering and that it has not verified a fund drain tied to a device bought outside Southeast Asia. Ledger's authenticity check cannot detect the added hardware, which shows the limit of attestation against reseller-channel tampering. The page text is only a teaser, so technical detail is limited.

Ledger disclosed that an organized group bought genuine hardware wallets, implanted hidden components that capture the 24-word recovery phrase during setup and send it over cellular networks, then fed the devices back in through resellers in Southeast Asia. Onchain researchers estimate up to $93M stolen across 300+ wallets, a figure Ledger has not confirmed. Ledger asked regional resellers to suspend sales, found no tampering in samples it inspected, and added reseller rules (no shelf display, report suspicious units, no resale of returned devices). It says its chips, OS and servers were not compromised.

News report on a Southeast Asia supply-chain breach in which Ledger devices sold via resellers such as CryptoBilis were modified with hidden chips. The chips read 24-word recovery phrases from the screen signals during setup and sent them out over LTE. Tether froze $10M USDT tied to the theft, and Ledger suspended sales in several Asian markets. It also covers Ledger's Android-based Atom signer, which adds a protective enclosure, screen and back-cover removal sensors with their own battery, tamper-evident packaging, and website-only initial sales.

Ledger asked resellers and distributors in Indonesia, Singapore, Thailand, the Philippines, Vietnam, Malaysia and Hong Kong to pull its hardware wallets while it investigates devices fitted with a hidden implant. Its Donjon team found the implant reads the 24-word recovery phrase from the screen during setup and sends it out over LTE. All confirmed losses trace to devices sold through reseller CryptoBilis, and Specter has traced over $86M in suspected thefts, which Ledger has not verified. Ledger says its own infrastructure and direct channel show no compromise. MediaMarkt Saturn halted sales after a German customer reported an implant, and Trezor is ending reseller authorizations on January 1, 2027.

Draft ERC from Quantova Inc proposing a "Quantum Bridge Shield" for Ethereum bridges. A committee signs the Merkle root of each message batch with RFC 8554 LMS hash-based signatures instead of ECDSA/BLS keys that Shor's algorithm can break. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain, chain, guard and epoch, and applies a 60-second delay. The post gives gas costs (LMS W4 height-10 verification about 205k gas, a LayerZero packet 128,683 gas, worst-case rotation 12.44M gas under the EIP-7825 cap) and cites a NioLabs assessment with no critical or high findings. It is relevant as a worked post-quantum migration design for bridge key custody, including hybrid ECDSA+LMS mode and stateful-signature pitfalls such as leaf reuse and rollback.

Draft ERC from Quantova Inc that has Ethereum bridges accept cross-chain message batches only when a committee signs the Merkle root with RFC 8554 LMS hash-based signatures. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain tag, chain ID, guard address and epoch, and enforces a 60-second delay. It reports gas benchmarks (about 205k per LMS W4 height-10 verify, 12.44M worst-case rotation under EIP-7825), a hybrid LMS+ECDSA migration mode, and a NioLabs assessment with no critical or high findings. It argues that Shor's algorithm makes secp256k1 and BLS committee keys a quantum theft target.

News roundup on hardware implants found in Ledger wallets sold through authorized resellers, starting with CryptoBilis in Southeast Asia and then Singapore, Japan and German MediaMarkt stores. The implants read the 24-word recovery phrase off the screen during setup and send it out over a hidden cellular link, while Ledger's secure chip stays untouched so the devices look genuine. Researchers describe three generations dating to 2025, each harder to detect. Suspected losses are put at $86M (Specter) to $103M (Yfarmx), and neither figure is verified by Ledger.

Ledger's Donjon team confirmed that Ledger signers sold by the reseller CryptoBilis contain an unauthorized implant. It captures the 24-word recovery phrase during setup and sends it over LTE using a provisioned eSIM. It does not touch the Secure Element, the OS, or transaction signing. Onchain researchers estimate losses above $86M, but Ledger says that figure is unverified. MediaMarkt Saturn halted European Ledger sales after a tampered unit was reported in Germany, and Trezor and OneKey tightened or revoked reseller authorizations. The case shows a reseller-channel tampering risk for hardware wallets.

Protos reports that German retailer MediaMarkt pulled all Ledger products after teardowns of Ledger hardware wallets showed physical spyware implants, tied to an $86M drain of wallets bought from Malaysian reseller CryptoBilis. Ledger's investigation concluded the implant recorded the 24-word recovery phrase and sent it out over an attached eSIM. Mark Karpelès has helped identify implants in dismantled devices from MediaMarkt, LazMall (Philippines), CryptoBilis and Metapod (Singapore airport). Ledger has so far confirmed only the CryptoBilis devices and says it is reviewing reports of implants elsewhere.

Ledger says some hardware wallets sold by the reseller CryptoBilis contained a covert implant inside the enclosure. Its microcontroller recognised the 24-word recovery phrase when it was displayed during setup and sent it to attackers over LTE using an eSIM. Ledger says its secure element, OS, transaction signing and internal systems were not compromised. Onchain researchers estimate up to $93.2M lost across more than 300 wallets, and Tether froze $10M of USDT. Ledger's guidance is not to initialize units bought from the reseller and to move funds to a new device with a fresh phrase if already used.

XRP Ledger maintainers disclosed a critical integer overflow in the payment engine, reported via bug bounty in September. A payment consuming hundreds of crafted order-book offers made the buyer's owed sum wrap around to a tiny value while sellers were paid in full, minting XRP. The built-in "no XRP created" invariant check used the same flawed arithmetic and missed it. The fix shipped in 3.4.1 on Sept. 25, bypassing the usual amendment vote and two-week wait for the first time, so the open-source patch would not expose a live exploit. No exploitation evidence was found.

Protos reports additional alleged Ledger hardware wallets with physical spyware implants, found in devices from a German MediaMarkt reseller, a Philippine LazMall reseller and a Stax model bought from CryptoBilis. Mark Karpelès found that the implants read the device's screen output to capture seed phrases and evade Ledger's Genuine Check. The earlier CryptoBilis-linked incident of Oct 9 drained over $86M. Ledger told resellers to use only authorized channels and never restock returned units, and teardowns have also shown many devices to be clean.

CoinDesk reports that up to $93–94.5M in mostly USDT and TRON tokens was drained from 315–521 wallets across six or seven blockchains. The wallets were tied to Ledger hardware wallets sold by the authorized reseller CryptoBilis. Ledger confirmed an unauthorized hardware implant in at least one device but did not say how the devices were tampered with. Tether froze $10M, some funds moved through Tornado Cash and Zcash, and Ledger told affected users not to set up unused devices and to move funds to a new device with a fresh recovery phrase. The figures come from Bitquery and YFarmX onchain estimates, not a confirmed Ledger loss total.
