The cryptocurrency community has been reminded yet again to remain vigilant in the bull market as a hardware wallet user has reported massive losses. The incident highlights the importance of staying informed and taking necessary precautions to prevent such attacks.
Massive Losses Reported by Hardware Wallet User
On December 13, Anchor Drops, a user on X, shared their personal experience with the social networking platform. They reported losing approximately $1 million in Bitcoin (BTC) from their Ledger Nano S wallet. In addition to the alleged loss of BTC, they also lost $1.5 million worth of non-fungible tokens (NFTs) stored in the same wallet.
Linking the Incident to a Phishing Hack
The cryptocurrency community and Ledger have linked the incident to a phishing hack that occurred several years ago but only recently surfaced. Ledger pointed to malicious transactions from years ago, which they believe are connected to the reported losses.
Ledger’s Statement on the Incident
Ledger told Cointelegraph that Anchor Drops "seems to have been a victim of phishing and malicious transactions many years ago." The wallet manufacturer referred to an X post by community member KDean, who linked the loss to a phishing transaction involving the hacked Ethereum address shared by Anchor Drops. Tagged ‘Fake_Phishing5443,’ the alleged phishing transaction occurred on February 22, 2022.
Blockchain Security Platforms Confirm Phishing Transaction
Several blockchain security platforms confirmed that the fishing transaction caught by KDean was likely the culprit of the losses. Hakan Unal, senior scientist at the blockchain security platform Cyvers, told Cointelegraph:
"Blockchain evidence shows they signed a phishing transaction nearly three years ago, unknowingly granting approval to a malicious actor. The hacker remained dormant for years before eventually draining the wallet."
Unal stressed that the incident has nothing to do with Ledger itself and encouraged users to follow best practices and regularly review token approvals to ensure their assets remain secure.
Questions Surrounding Bitcoin Loss
While the NFT losses were tied to Ethereum transactions, it remains unclear how the malicious activity extended to the user’s Bitcoin holdings. Fuzzland’s lead security researcher Tony Ke told Cointelegraph:
"For the NFT, KDean’s comment can explain everything. But I don’t understand how the BTC is stolen."
Cyvers and Ledger Suggest Malicious Transaction on Ethereum Expanded to Other Blockchains
Cyvers and Ledger suggested that a malicious transaction on Ethereum could have expanded to more blockchains within a wallet. If the phishing attempt also captured the user’s recovery phrase, the attacker could gain access to the wallet across all supported chains, including Bitcoin.

Fuzzland’s Ke added:
"It’s essential to regularly review token approvals and ensure that your assets remain secure."
