Hardware wallet manufacturer Ledger has verified that a physical unit associated with recent thefts of user assets contained an unauthorized hardware modification. According to the enterprise, every verified instance discovered thus far involves merchandise supplied by the Southeast Asian distributor CryptoBilis.
In a formal announcement published on October 10, Ledger Support stated, “Ledger can confirm that one of the impacted users’ devices contained an unauthorized hardware implant.” The organization further noted that it is actively reaching out to affected clients as part of an ongoing probe, while CryptoBilis has halted all hardware wallet sales until the inquiry concludes.
During a subsequent update on October 11, Ledger pointed out that the scale of compromised units appears restricted. “To date, all confirmed cases related to the disclosed draining incident of Oct 9th, 2026, involve devices sold through the Southeast Asia reseller CryptoBilis,” the firm explained, stressing that its internal network and official sales pipelines remain completely uncompromised.
The validation of a physical modification provides the initial definitive proof backing up earlier theories of supply chain interference.
The matter first emerged on Friday when Ledger acknowledged examining reports regarding missing client funds originating from purchasers who bought hardware through CryptoBilis, a vendor operating within Indonesia, Malaysia, and the Philippines.
Although Ledger has not formally verified a specific financial loss, independent blockchain researchers have estimated the damages between $86 million and $93 million extracted from upward of 300 wallets spanning multiple networks like Bitcoin, Ethereum, and Tron. The business reiterated that no signs indicate its proprietary security architecture, internal networks, or operational services were breached.
Ledger reported it is collaborating with relevant law enforcement on Sunday. The corporation also reminded its network of suppliers to procure merchandise strictly via official pathways and explicitly forbade restocking returned items.
The company reiterated previous security instructions directed at clients who acquired units through CryptoBilis: “Do not initialize unused devices. If already set up, move to a new seed on a device from Ledger.” The organization strongly encouraged impacted individuals to reach out to official Ledger Support and submit reports to local authorities.
Ledger also cautioned that malicious actors frequently try to capitalize on these situations, reminding users that the enterprise will never call, send direct messages, or request a 24-word recovery phrase.
When will wallets be SAFU?
The Ledger event has once again sparked broader industry discussions regarding the security of hardware wallets. Following the collapse of the FTX platform in 2022, countless investors shifted their wealth into self-custody solutions, depending heavily on physical security modules produced by companies such as Ledger and Coinkite (creators of Coldcard) to keep private keys offline.
In practice, however, physical storage solutions have not proven immune to vulnerabilities.
Back in July 2026, a vulnerability inside the seed-generation firmware of Coldcard enabled malicious actors to drain roughly $100 million to $130 million worth of bitcoin, according to findings from on-chain analysts.
Regarding the current breach, Ledger maintains that the physical interference is strictly confined to the shipment batch handled by CryptoBilis, and it is executing necessary measures to prevent similar threats.
“Security isn’t static and this incident underscores why we continuously review and strengthen our distribution and anti-tamper processes,” Ledger stated in its October 11 statement.
The enterprise added that it is evaluating certified reseller protocols, enhancing physical security features, and advocating for enhanced supply chain accountability across the broader sector.
Even so, speculation concerning the exact breach vector of the supply chain persists.
Via a post on X, Binance co-founder Changpeng Zhao (CZ) claimed that the perpetrators “apparently bought the reseller and made them sign a non-disclosure agreement to keep their mouth shut.”
These statements have not been independently verified. CryptoBilis did not immediately reply to inquiries concerning the incident or Zhao’s assertions.
