Reflective PE loading is a technique used in cybersecurity attacks where a Portable Executable (PE) file, such as a Windows executable or DLL, is loaded directly into a computer’s memory without being written to disk. This method allows attackers to execute malicious code stealthily, as traditional antivirus solutions often rely on scanning files stored on disk. By avoiding disk operations, reflective PE loading can bypass many security controls and leave minimal forensic evidence. This technique is commonly used in fileless malware attacks and advanced persistent threats (APTs) to evade detection and maintain persistence on compromised systems.
