Malicious Code Extension

Definition ∞ A malicious code extension is software designed to operate within a larger program, carrying out harmful or unauthorized actions. In the digital asset space, this typically refers to browser extensions, wallet plugins, or smart contract additions that secretly execute harmful commands, such as stealing private keys, redirecting transactions, or draining cryptocurrency wallets. These extensions often masquerade as legitimate tools or updates, deceiving users into granting permissions that compromise their digital security. Their objective is often to gain illicit access to user funds or data.
