As the cryptocurrency market continues to experience a bull run, a recent incident has served as a stark reminder for users to remain vigilant against potential threats. A hardware wallet user, identified by their username ‘Anchor Drops’ on X, reported significant losses on December 13, which have been linked to a phishing attack.
Massive Losses Linked to Phishing Attack
The user, Anchor Drops, claimed to have lost approximately $1 million in Bitcoin (BTC) and $1.5 million worth of non-fungible tokens (NFTs) stored on their Ledger Nano S wallet. This incident has sparked concerns within the cryptocurrency community, with many users expressing surprise that such a large loss could occur despite the use of a hardware wallet.
Ledger Links Incident to Phishing Hack
In an effort to clarify the situation, Ledger took to X to address the incident and provided further information on the alleged phishing hack. According to Ledger, Anchor Drops’ losses appear to be linked to a malicious transaction that occurred in 2022.
Phishing Transaction Involving Ethereum Address
As revealed by community member KDean’s post, the alleged phishing transaction involved an Ethereum address shared by Anchor Drops. This malicious activity is believed to have taken place on February 22, 2022, and was linked to a user account known as ‘Fake_Phishing5443.’
Blockchain Security Platforms Confirm Incident
Several blockchain security platforms have confirmed that the phishing transaction identified by KDean is likely responsible for the losses suffered by Anchor Drops. Hakan Unal, senior scientist at Cyvers, stated:
"The hacker remained dormant for years before eventually draining the wallet."
Unal emphasized that this incident has nothing to do with Ledger itself and instead highlights the importance of users following best practices when interacting with their wallets.
Questions Surround Bitcoin Loss
While the NFT losses can be explained by the phishing transaction on Ethereum, it remains unclear how the malicious activity extended to the user’s Bitcoin holdings. As Fuzzland’s lead security researcher Tony Ke pointed out:
"For the NFT, KDean’s comment can explain everything. But I don’t understand how the BTC is stolen."
Phishing Transaction Timeline
The phishing transaction ‘Fake_Phishing5443’ occurred 1,019 days ago, raising questions about why it has only surfaced now.
Cyvers and Ledger Suggest Phishing Attempt Could Have Expanded to More Blockchains
In an effort to shed more light on the incident, Cyvers suggested that a malicious transaction on Ethereum could have expanded to other blockchains within the wallet. According to Cyvers:
"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."
Ledger’s spokesperson echoed this sentiment, stating that if the user’s recovery phrase was compromised, it is possible that the malicious activity extended to other blockchains.
Incident Highlights Importance of User Vigilance
Following the incident, Ledger has strongly advised users to be vigilant when signing any transactions on-chain. Fuzzland’s Ke emphasized:
"While using hardware wallets is crucial in terms of security enhancement, it’s equally important to understand every interaction with the wallet and make informed decisions."
This warning serves as a stark reminder for cryptocurrency users to remain cautious against potential threats and to regularly review their token approvals.
Staying Vigilant in the Bull Market
As the cryptocurrency market continues to experience a bull run, it is essential that users stay vigilant against potential threats. This incident highlights the importance of user education and awareness when interacting with their wallets.
Best Practices for Hardware Wallet Users
- Regularly review token approvals
