Multi-Stage Infection

Definition ∞ A multi-stage infection refers to a cyberattack where malicious software deploys its harmful components in sequential phases. This infection strategy often begins with a seemingly innocuous initial payload that establishes a foothold, then downloads and executes additional malicious modules. Each stage may perform different functions, such as reconnaissance, privilege escalation, or ultimately, the exfiltration of sensitive data like cryptocurrency private keys. This phased approach helps evade detection by security systems and complicates forensic analysis.
Context ∞ Multi-stage infections are frequently reported in cybersecurity news related to digital asset theft, as attackers employ sophisticated methods to compromise cryptocurrency wallets and exchange accounts. Understanding these attack patterns is vital for developing effective defensive strategies against persistent threats. Security researchers often analyze the stages of such infections to identify indicators of compromise and improve threat intelligence.
