How the Ledger Connect hacker tricked users

Exploitation through tricking Web3 users The “Ledger hacker,” who siphoned at least $484,000 from multiple Web3 apps on Dec. 14, did so by tricking Web3 users into making malicious token approvals, according to the team behind blockchain security platform Cyvers. This highlights the importance of user education and vigilance when it comes to interacting with decentralized applications.

Use of malicious token approvals The hacker utilized a phishing exploit to compromise the computer of a former Ledger employee, gaining access to the employee’s node package manager javascript account. This allowed them to trick Web3 users into unknowingly making approvals for malicious tokens, ultimately leading to the theft of funds.

Involvement of blockchain security platform Cyvers Cyvers played an instrumental role in identifying and analyzing the exploit used by the Ledger hacker. Their expertise in blockchain security helped shed light on the methods employed by the attacker, providing valuable insights for future prevention and mitigation strategies.
