Reported losses linked to suspected Ledger wallet thefts are nearing $90 million, while Tether has frozen USDT investigators linked to the incident. Ledger says it is investigating reports involving devices bought from CryptoBilis, an authorized reseller in Southeast Asia, and asked the distributor to pause sales and shipments.
Ledger advised customers who bought from CryptoBilis in the past 90 days not to initialize devices that are still unused. Customers who already set them up were urged to consider moving funds to a new Ledger device initialized with a fresh recovery phrase. Investigators have not confirmed how many devices were affected or whether the thefts stemmed from counterfeit hardware, physical tampering or another cause.
Why it matters
The case raises questions about hardware-wallet supply chains and the limits of device authentication. Ledger's documentation says its Genuine Check verifies a device's Secure Element but may not detect physical changes elsewhere in the hardware if that chip remains intact. There is no confirmed evidence that malicious hardware implants caused the reported thefts.
Changpeng Zhao described the suspected attack as localized to one vendor and urged industry players to help trace and recover funds. Former Mt. Gox CEO Mark Karpelès has asked CryptoBilis to open unsold devices for inspection of their circuit boards.
Market impact
Estimates vary: investigator Specter initially put suspected losses above $86 million, while MistTrack later estimated them at nearly $90 million. Those figures have not been independently verified, and investigators have not established that every wallet counted was compromised in the same operation.
Tether's freeze can stop transfers of affected USDT from designated addresses, but it does not automatically return tokens to their owners. The reported thefts also span Bitcoin, Ethereum and Tron, and Tether cannot freeze native Bitcoin or Ethereum. Investigators have not disclosed the value of the restricted USDT, leaving the potential recovery share unclear.
Frequently asked questions
-
How much has reportedly been stolen in the suspected Ledger incident?
Estimates range from more than $86 million to nearly $90 million. Investigators have not independently verified the totals or confirmed that every wallet counted was affected by the same operation.
-
What did Ledger advise customers who bought from CryptoBilis?
Customers who bought a device in the past 90 days were advised not to initialize it if setup was incomplete. Those who had already configured it were urged to consider transferring funds to a new Ledger device with a fresh recovery phrase.
-
What can Tether's freeze do to the linked USDT?
The freeze can prevent transfers of affected USDT from designated addresses. It does not automatically return tokens to their owners, and the value of the restricted USDT has not been disclosed.
-
Why might Ledger's Genuine Check not detect every hardware modification?
Ledger says the check verifies a device's Secure Element but may not identify physical changes elsewhere in the hardware if that security chip remains intact.
-
Why can't Tether freeze all assets linked to the reported thefts?
The suspected thefts span Bitcoin, Ethereum and Tron, as well as USDT. Tether cannot directly freeze native Bitcoin or Ethereum, so investigators may need cooperation from exchanges, custodians and law enforcement.
