Definition ∞ Defense evasion tactics are techniques employed by malicious actors to avoid detection by security systems and tools. These methods include obfuscating malware code, using legitimate system processes, disabling security software, or exploiting vulnerabilities to bypass firewalls and intrusion detection systems. The objective is to maintain persistence and execute harmful actions without triggering alerts. These tactics constantly evolve to counter new defenses.
Context ∞ In the cryptocurrency and digital asset domain, defense evasion tactics are critical for cybercriminals seeking to compromise wallets, exchanges, or smart contracts. News reports frequently detail new evasion techniques discovered in malware campaigns targeting crypto users. Understanding these tactics is essential for developing robust cybersecurity solutions and threat intelligence to protect digital assets. Security researchers continually analyze and report on these evolving adversarial strategies.
