To scale protection, we employ machine learning technologies to sort through this massive amount of information and determine a verdict for analyzed files. The volume of detonated threats translate to millions of signals that need to be inspected. These automated systems include a robust detonation platform, heuristics, and machine learning models.Р”Вetonation in controlled environments exposes thousands of signals about a file, including behaviors like dropped and downloaded files, registry manipulation for persistence and storing stolen information, outbound network connections, etc. Office 365 ATP protects customers from unknown email threats in real-time by using intelligent systems that inspect attachments and links for malicious content. These techniques include multiple redirections, large dynamic and obfuscated scripts, HTML for tag manipulation, and others. Typical email attack chain Detonation-based heuristics and machine learningР”Р„ttackers employ several techniques to evade file-based detection of attachments and blocking of malicious URLs. Every month, Office 365 ATP blocks more than 500,000 email messages that use malicious HTML and document files that open a website with malicious content.Р”Р‡igure 1. These file types allow attackers to constantly tweak email campaigns to try slipping past security defenses. Attackers use non-PE file formats because these can be easily modified, obfuscated, and made polymorphic. Modern email attacks combine sophisticated social engineering techniques with malicious links or non-portable executable (PE) attachments like HTML or document files to distribute malware or steal user credentials. Machine learning technologies, powered by expert input from security researchers, automated systems, and threat intelligence, enable us to build and scale defenses that protect customers against threats in real-time.

Office 365 Advanced Threat Protection (ATP) uses a comprehensive and multi-layered solution to protect mailboxes, files, online storage, and applications against a wide range of threats.
