What are the key techniques used in malware evasion?

### REPLY:
Malware evasion techniques involve using advanced anti-virtualization and anti-sandboxing mechanisms to avoid detection. Additionally, employing rootkit technology can help hide the presence of malware on the infected system. By encrypting or compressing the malicious code, it becomes harder for security tools to identify the malware. Moreover, exploiting zero-day vulnerabilities can allow malware to bypass security measures and remain undetected.
