Definition ∞ Transaction instruction manipulation involves altering the parameters or data of a digital asset transaction without the user’s explicit knowledge or consent. This malicious act can redirect funds, change recipient addresses, or modify transaction amounts. Attackers typically achieve this by compromising a user’s device, browser, or an intermediary service. It represents a direct attack on the integrity and security of a user’s financial operations.
Context ∞ Transaction instruction manipulation is a severe security threat in the digital asset space, often facilitated by sophisticated malware or phishing attacks that intercept and alter transaction details before submission. Users might unknowingly approve a modified transaction, leading to irreversible loss of funds. The development of hardware wallets and multi-signature schemes aims to mitigate this risk by providing additional layers of verification. Educating users on verifying transaction details thoroughly before signing remains a crucial defense.
