In the ever-evolving landscape of cybersecurity, attackers are constantly refining their techniques to slip past traditional defenses. One such method that has gained traction among Advanced Persistent Threat (APT) groups and cybercriminals is PPSideLoader .

As macro-based attacks decline, sideloading techniques like PPSideLoader will become the new normal. Defenders must shift from trusting file extensions and signatures to monitoring —because even a trusted app like PowerPoint can become a backdoor when loaded the wrong way. ppsideloader

Here is everything you need to know about how it works, why it is dangerous, and how to stop it. PPSideLoader is a DLL sideloading attack that leverages Microsoft PowerPoint’s slide show mode. In a standard DLL sideloading attack, an attacker tricks a legitimate application into loading a malicious Dynamic Link Library (DLL) file instead of the legitimate one. Defenders must shift from trusting file extensions and

PPSideLoader takes this concept and applies it specifically to PowerPoint. Attackers package a malicious DLL alongside a legitimate PowerPoint executable (or related component). When PowerPoint runs a slideshow, it looks for specific supporting files. If an attacker has placed a poisoned DLL in the same directory, PowerPoint will load it—granting the attacker code execution on the victim’s machine. Unlike macro-based attacks (which require the user to enable scripts), PPSideLoader relies on file system behavior and search order hijacking. In a standard DLL sideloading attack, an attacker
