A Ledger User Deposited 7 Million USDT Just Three Weeks After Purchasing the Device

BlockBeats reported on October 9 that multiple users who purchased Ledger hardware wallets from CryptoBillis had funds stolen, with cumulative losses close to $90 million.

Largest individual loss: 7 million USDT drained

On-chain tracker lookonchain monitored address TY24Ya. The user bought a Ledger device from CryptoBillis three weeks earlier and deposited 7 million USDT. About 10 hours before the report, the entire balance was stolen, making it one of the largest individual losses in the incident.

Cause is not confirmed

There is no confirmed evidence that the devices were tampered with. The technical cause of the theft and the attacker's identity remain unproven. Hardware wallets are generally designed to keep private keys offline, but security also depends on device authenticity, the setup process, and how recovery phrases are handled.

What the incident means for users

The case highlights the risk of buying hardware wallets through third-party sales channels rather than trusted sources. Users should be cautious about unknown supply paths and avoid exposing wallet setup information to others.

Background on the devices and the asset type

Ledger hardware wallets are often described as cold-storage tools: their intended role is to keep private keys away from internet-connected computers, while allowing users to approve transactions through the device. USDT is commonly understood as a stablecoin-style token whose value is generally associated with attempts to track a fiat currency. In incidents involving large token balances, the concern is not only price volatility, but also whether the asset can be transferred quickly once access to keys or approval authority is compromised.

Why supply-chain concerns matter

A hardware wallet can only provide the protection it is designed to provide if the device is authentic, initialized correctly, and never exposed to malicious instructions. Third-party distribution channels may create additional uncertainty because buyers may not be able to verify the full path from manufacturer to end user. Possible concerns include altered packaging, pre-activation, replacement of a legitimate device with a counterfeit, or social-engineering attempts that ask for recovery phrases. These possibilities are general risk categories, not confirmed conclusions about this case.

What remains unresolved

Because the technical cause is not confirmed, it is important to separate observed on-chain movement from proven root cause. Monitoring services can track addresses and balances, but public reports alone may not show whether theft occurred through device firmware, setup interference, phishing, compromised credentials, or another method. Until further evidence is available, the most defensible conclusion is that users should treat the incident as a warning about wallet acquisition, initialization, and operational hygiene.

Practical lessons

Users who want hardware-wallet protection should prioritize trusted sources, verify packaging where possible, and initialize devices in an environment where no one else can observe or interfere. Recovery phrases should never be shared, photographed, stored online, or entered into websites that claim to activate, update, or support the device. Large balances also warrant stronger habits: separating storage, limiting exposed assets, and keeping transaction approval steps isolated from everyday online activity.

Risk Warning

This article is only a compilation of publicly reported information and does not constitute investment, trading, or security advice. Cryptocurrency prices can be highly volatile, and hardware wallets purchased through unverified third-party channels may involve serious risks, including device tampering, key exposure, and irreversible loss of funds. Readers should verify sources, protect recovery phrases, and make independent, rational decisions based on their own risk tolerance. Any investment carries potential losses, and past incidents do not guarantee future outcomes.
