Idea
A defense-enhanced malware detection system improving robustness against byte-level adversarial attacks for email security providers.
Research Paper
Core Innovation
This paper presents a case study of Gmail's malware detection pipeline vulnerability to byte-level adversarial attacks targeting the Magika routing model. It demonstrates a novel attack that modifies minimal bytes to evade detection and proposes a practical defense that significantly raises the attack cost. The defense has been validated and deployed in a real-world production environment.
Market Size (TAM)
$20–50B TAM for cybersecurity and malware detection; $2–10B SAM from email providers and enterprise security. Driven by increasing malware sophistication and regulatory compliance needs.

Research Paper Overview
Evaluating the Robustness of a Production Malware Detection System to Transferable Adversarial Attacks
Summary
This paper analyzes how adversarial attacks on a machine learning component can compromise Gmail's malware detection pipeline by fooling the Magika model that routes malware samples to specialized classifiers. By modifying just 13 bytes, attackers can evade detection in 90% of cases. The authors develop a defense that increases the byte modification requirement to 50 bytes for a 20% success rate, which has been deployed in Gmail's production system.
