Wallet Drainer

Definition ∞ A wallet drainer is a type of malicious software or script designed to steal funds from cryptocurrency wallets. It typically operates by tricking users into approving transactions that transfer their digital assets to an attacker-controlled address. This is a common vector for cryptocurrency theft.
Context ∞ In the digital asset space, wallet drainers are frequently deployed through phishing websites, compromised smart contracts, or malicious browser extensions. The primary concern is the direct loss of user funds, necessitating robust security practices such as transaction verification and the use of hardware wallets. Ongoing efforts focus on identifying and disabling these drainer operations and educating users about the associated risks.
