DLL side-loading is a cyberattack where a malicious Dynamic Link Library file is placed in a legitimate application’s execution path. The application then inadvertently loads and executes the attacker’s code instead of the intended system library. This technique grants unauthorized access or control over the compromised system. It exploits how applications search for and load external code components.
Context
In the digital asset security landscape, DLL side-loading represents a persistent threat, often targeting software wallets or trading applications. News reports frequently detail instances where this method is used to gain access to private keys or siphon funds. Preventing such attacks involves rigorous software security practices, including code signing and strict path validation, alongside user vigilance regarding application sources.
Sophisticated phishing leverages DLL side-loading and clipboard hijacking, enabling silent cryptocurrency diversion and data exfiltration from unsuspecting users.
