Role Summary
Malware Researcher? Red/Blue/Purple team member? We have a fantastic opportunity here at Sophos Labs for a Threat Researcher role to join our global team of Behavioral Protection engineers, to hunt, to research, and to add real-time protection for suspicious activity across our customer environments. Our team of skilled security experts combine their passion to detect & disrupt cyber-attacks with their capability to develop protection rules that can cut through the noise in modern computing environments to tease out attacker’s nefarious activities. You are intrinsically motivated to understand the core logic behind malware and hacking attacks, to find & predict new ways attackers will modify their techniques and take great satisfaction in developing robust protection logic that is immune to evasive actions. You will be responsible for writing behavioral protection rules that are able to block malicious activities across all types of TTP (even if a Mitre Technique doesn’t exist yet). This is the foundation of Sophos next-gen approach. Above all - you enjoy thinking creatively; combining your deep technical knowledge, your tenacity for innovation, and your can-do attitude to solve complex and challenging problems on daily basis. Additionally, you will also be supporting our remediation effort to remove artifacts left behind, by writing cleanup rules, and supporting our Sandbox development, such as (but not limited to) creating signatures, identifying evasion techniques that prevent the sandbox from running the threat smoothly.What You Will Do
