Definition ∞ Wallet drainers are malicious scripts or websites designed to surreptitiously transfer all digital assets from a user’s cryptocurrency wallet. These sophisticated phishing tools often mimic legitimate decentralized applications (dApps) or trading platforms, tricking users into signing malicious transactions that grant the attacker broad permissions over their funds. Once activated, a wallet drainer can rapidly empty all connected assets, including cryptocurrencies and NFTs, from the victim’s address. They exploit trust and a lack of user scrutiny.
Context ∞ Wallet drainers are a significant and growing threat frequently covered in crypto news, causing substantial losses for unsuspecting users across various blockchain networks. Reports detail how these scams are distributed via compromised social media accounts, fake airdrops, or deceptive advertisements. Awareness of these predatory tactics and extreme caution when connecting wallets to unfamiliar sites are absolutely critical for digital asset security.
