Definition ∞ Process injection is a stealth technique used by malicious software to execute arbitrary code within the address space of another running process. This method allows malware to hide its operations, evade detection by security software, and gain access to the resources or privileges of the legitimate process. It involves writing malicious code into a target process’s memory and then forcing the target process to execute it. This is a common tactic for privilege escalation and persistence.
Context ∞ Process injection is a dangerous cyberattack technique that poses a significant threat to systems handling digital assets, including cryptocurrency wallets and exchange clients. News reports occasionally detail how malware uses process injection to compromise legitimate applications, steal private keys, or siphon funds. Cybersecurity professionals constantly work to develop countermeasures and detection methods to protect users from these sophisticated attacks.
