What are some common techniques used in malware evasion?

### REPLY:
One effective technique for malware evasion is to use zero-day exploits, which are vulnerabilities that are unknown to software vendors and have no available patches. By exploiting these vulnerabilities, malware can bypass security measures and infect systems without being detected. Additionally, using fileless malware, which resides only in memory and does not leave traces on the disk, can also help evade detection by traditional antivirus software.
