As attackers increasing employ stealthier methods to avoid detection, Azure Security Center is extending fileless attack detection for Linux, in addition to Windows. Fileless attacks exploit software vulnerabilities, inject malicious payloads into benign system processes, and hide in memory. These techniques minimize or eliminate traces of malware on disk and greatly reduce the chances of detection by disk-based malware scanning solutions.
To counter this threat, Azure Security Center released fileless attack detection for Windows in October 2018, and has now extended fileless attack detection on Linux as well.
