Role Summary

Threat hunter? Programmer? Data-driven?

We have a fantastic opportunity here at Sophos Labs for a Threat Researcher to join our global team of behaviour-based detection engineers, to hunt, to research, and to add real-time detection 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 classification 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 detection logic that is immune to evasive actions. You will be responsible for writing rules that are able to detect 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 a daily basis.

What You Will Do

Understand malware kill chain and lifecycle & hands-on-keyboard attacks

Mapping TTPs to MITRE ATT&CK matrix

Accurate & efficient classification of malicious & suspicious behaviour

Author classification rules, for both Endpoint & Cloud scenarios, to identify malicious & suspicious use of TTPs

Analyse real world kill chains to discover new TTPs and gaps in coverage

Measure and tune TTP coverage through data mining, customer telemetry & internal sandbox feeds

Build & maintain playbooks on threat actor TTPs

What You Will Bring

Strong knowledge of Windows or MAC operating system, internals & forensic tools

Demonstrated programming experience. Preferred: Python, Lua, RegEx and/or SQL.

Excellent grasp of MITRE ATT&CK tactics, techniques & procedures in order to create simulation

Familiar with computational cost analysis & problem solving to minimize impact

Bachelor degree in Computer Software (Computer Security preferable)

Big data experience, Elastic Search, Kibana, Redshift

SDLC or CI/CD Knowledge is a plus

Bachelor’s degree in computer software (Computer Security preferable) or equivalent experience
