Crypto drainers are malicious scripts designed to steal cryptocurrency from user wallets, tricking individuals into authorizing transactions unknowingly. They often masquerade as legitimate projects and are proliferated through compromised social media accounts. The growing threat of crypto drainers is exacerbated by Crypto Drainers-as-a-Service (DaaS), which offers ready-made draining scripts for a share of the stolen funds. DaaS tools include JavaScript-based drainers, token approval malware, and clipboard hijackers, making it accessible even to low-skill scammers. In 2023, phishing campaigns using drainers led to losses of over $295 million. Key indicators of a crypto drainer attack include unusual transactions, loss of wallet access, and alerts from wallet providers. To protect against such threats, users should utilize hardware wallets, enable two-factor authentication, avoid phishing links, and regularly monitor wallet activity. If a wallet is compromised, it is crucial to change passwords, notify providers, and report to authorities for assistance.
