Pakistan

Message

At Rewterz, I led the SOC team delivering detection and response for Faysal Bank before transitioning into a dedicated DFIR role. I’ve investigated incidents across banking, financial services, and oil and gas, using memory, disk, and log analysis to establish root cause and scope.

I also played a hands-on role in incident response and forensic analysis for the 2021 National Bank of Pakistan cyber incident. I build and tune detections across SIEM platforms, automate repetitive SOC workflows with SIRP and AI-assisted tooling, and align investigations and detection coverage with MITRE ATT&CK and NIST frameworks.
