• Ledger emphasized user vigilance and reviewing token approvals to prevent theft.
• Phishing exposed recovery phrases, highlighting risks despite using hardware wallets.

The cryptocurrency community is grappling with a sobering security breach involving a Ledger Nano S wallet. A user known as “Anchor Drops” on X reported losing 10 Bitcoin (BTC) valued at around $1 million and $1.5 million in NFTs. Despite claims of keeping the seed phrase offline and untouched for months, the wallet’s contents were drained.

Anchor Drops asserted no suspicious transactions were signed knowingly, sparking intense debate about the security breach’s origin. Ledger, the wallet’s manufacturer, addressed the situation, reiterating the strength of their Secure Element chip, which isolates sensitive data to prevent tampering. However, they hinted that a phishing attack or seed phrase exposure could be responsible.

Moreover, Blockchain analysis later uncovered a phishing attack dating back to February 22, 2022, tagged “Fake_Phishing5443.” According to cybersecurity experts, this transaction provided malicious actors with access permissions to the wallet. Although dormant for nearly three years, the attackers exploited this vulnerability to seize the assets.

The theft of Ethereum-based NFTs was explained through the phishing transaction, but questions remain about the stolen BTC. Blockchain security researchers suggest that the recovery phrase might have been compromised during the phishing attack, enabling the theft of multi-blockchain assets.
