Trezor warns of suspected crypto-theft implant in hardware wallet

Trezor warns of a suspected crypto-theft implant in a Trezor Safe 5 sold by reseller CryptoBilis in Southeast Asia. An Indonesian buyer found an extra board with a cellular module and antenna between the main board and screen, apparently able to read the recovery phrase and send it over mobile networks. Trezor has not examined the device, advises moving funds to a new wallet for any CryptoBilis purchase since March 2026, and notes a similar Ledger implant was confirmed.

Trezor hardware implant report: CryptoBilis buyers urged to move funds

Trezor advised everyone who bought wallets from reseller CryptoBilis since March 2026 to move funds to a new wallet with a new recovery phrase. An Indonesian customer reported a Safe 5 bought via Tokopedia in August 2026 with an extra board holding a cellular module that allegedly sends the wallet backup out. Trezor has not yet examined the device. Ledger separately confirmed tampering on CryptoBilis devices in October 2026.

Explained: The Ledger Supply Chain Incident (October 2026)

The Ledger supply chain incident of October 2026: on-chain analysis estimates $93 million was stolen after devices sold by the reseller CryptoBilis carried an implant with an eSIM. 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.

Weekly Research Brief: Ledger’s $91M Theft, Papertrade

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.

Inside the $91M Ledger Reseller Wallet Theft

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.

Karpelès Reports Ledger Implants in Devices From Two More Resellers

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 Officially Responds to Hardware Wallet Attack

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.

Ledger’s Atom device adds tamper detection after a recovery-phrase breach

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 Asks Resellers in Seven Asian Markets to Pull Devices After Suspected $86M Drain

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.

Ledger Spyware Scare Spreads Across Asia and Europe

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 confirms hardware implant in CryptoBilis reseller units as MediaMarkt suspends sales in Europe

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.

German Ledger reseller pauses sales following $86M draining incident

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 hardware wallet breach exposes LTE implant stealing recovery phrases

Ledger's Donjon team confirmed on October 10, 2026 a physical implant inside a hardware wallet sold by Malaysia-based reseller CryptoBilis. The implant reads the device display, decodes the 24-word recovery phrase with a microcontroller, and exfiltrates it over LTE via a provisioned eSIM, leaving the Secure Element, OS, transactions and signatures untouched. Onchain investigator Specter traced over $86 million in suspected thefts across Ethereum, Tron and Bitcoin; Ledger advises CryptoBilis buyers to migrate funds to a new device with a new recovery phrase.

$86 Million Crypto Heist Linked to Ledger Signer Hardware Implant

SecurityWeek reports that Ledger signers sold through the Southeast Asia reseller CryptoBilis had a hardware implant soldered onto the circuit board. The implant reads the screen during setup, decodes the 24-word recovery phrase with a microcontroller and sends it over LTE through a provisioned eSIM. Ledger says all confirmed losses trace to CryptoBilis devices and advises buyers from the last 90 days to move funds to a new signer with a new seed. On-chain investigator Specter puts losses at up to $86M, a figure Ledger has not confirmed.

CoinDesk reports that Ledger confirmed an unauthorized hardware implant in at least one device sold by the Southeast Asian reseller CryptoBilis. On-chain researchers estimate $86–93M was drained from more than 300 wallets across Bitcoin, Ethereum and Tron. Ledger says its internal systems and direct sales are unaffected, and it advises not initializing unused devices and moving funds to a new seed on a device bought directly from Ledger. It also covers the reseller's sales suspension, Ledger's tightened distributor chain-of-custody rules, unverified speculation that the reseller was bought out, and the July 2026 Coldcard seed-generation flaw.

XRP Ledger patches decade-old bug that could have minted trillions of XRP

The Block reports on the XRP Ledger disclosure of a critical bug that had been in the payment engine since 2015. Order-book offer totals had no overflow check, so a single payment consuming a few hundred crafted offers could wrap the sum and mint spendable XRP past the 100B cap. Veria Labs' AI agent found it and built a working exploit, and RippleX shipped the fix in xrpld 3.4.1 on Sept. 25, bypassing the usual amendment vote to avoid tipping off attackers. The article also covers the $250K bounty, a separate Batch bug, and the closed-source-release criticism.

An XRP Ledger security bug could have created 18.45 trillion XRP

Reports a decade-old integer overflow in the XRP Ledger payment engine's DEX offer-crossing code (added 2015). A single transaction across hundreds of seeded accounts could have minted about 18.45 trillion XRP, because the overflowed total understated what the buyer paid and the mint-check safeguard used the same wrong total. Veria AI found it on 2026-09-21 and reported it through the bug bounty. RippleX reproduced it on a standalone server and shipped xrpld 3.4.1 on 2026-09-25 as binaries only, with no patch source. RippleX's Mayukha Vadari warns that AI makes silent critical patches easy to reverse engineer, and the withheld source drew open-source criticism.
