Warning Signs in the Bull Market: A Reminder for Cryptocurrency Users
The cryptocurrency community has once again been reminded to remain vigilant, especially during a bull market, after a hardware wallet user reported massive losses linked to a phishing attack. This serves as a stark reminder that even with enhanced security measures in place, users must stay aware of potential threats.
A Personal Loss of $1 Million in BTC and NFTs
Anchor Drops, an X user, shared their personal experience on December 13, reporting losses of approximately $1 million in Bitcoin (BTC) stored in their Ledger Nano S wallet. In addition to the loss of BTC, Anchor Drops also reported losing a staggering $1.5 million worth of non-fungible tokens (NFTs) stored within the same wallet.
The Phishing Attack: A Malicious Transaction from Years Ago
Ledger has pointed out that the incident appears to be linked to an earlier phishing hack that occurred in February 2022 but was only recently uncovered. The wallet manufacturer noted that Anchor Drops seems to have been a victim of phishing and malicious transactions several years ago.
Blockchain Evidence Points to Phishing Transaction as Likely Culprit
Several blockchain security platforms confirmed that the phishing transaction caught by KDean, a community member, is believed to be responsible for the losses. Hakan Unal, senior scientist at Cyvers, stated, "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.
Understanding the Incident and Lessons Learned
While the NFT losses were tied to Ethereum transactions, there are still questions surrounding how the malicious activity extended to the user’s Bitcoin holdings. Fuzzland’s lead security researcher Tony Ke expressed his concerns, "For the NFT, KDean’s comment can explain everything. But I don’t understand how the BTC is stolen."
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.
Lessons for Users: Vigilance is Key
Following the incident, Ledger strongly advised users to be vigilant while signing any transactions on-chain. 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.
As Fuzzland’s Ke noted, "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."
