Abhijith S

Security-focused Computer Science graduate (B.Tech, LPU) with hands-on experience in network administration, identifying attack vectors, analyzing compromised systems, and mapping adversary TTPs to MITRE ATT&CK as well as incident response, threat detection, and cloud security monitoring. Led a full-scope incident response engagement for a client organization, investigating a 15-host malware outbreak from initial triage through containment and remediation, and tracing the intrusion to nation-state-linked C2 infrastructure along the way. Backed by five industry certifications with a consistent track record of turning that knowledge into deployable tooling, including a kernel-level ransomware detection engine and an automated cloud threat-monitoring system.

Looking to bring this investigative rigor and tooling mindset to a SOC or incident response team operating in a production security environment.

IR Lead Investigator at Independent (2026-06 – Present)

Led a full-scope incident response engagement across 15 hosts in a compromised flat LAN environment, identifying the attack surface and infection vectors during triage, containment, and eradication.

• Led a full-scope incident response investigation across 15 hosts in a compromised flat LAN environment, identifying the attack surface and infection vectors during triage, containment, and eradication.
• Reverse-engineered 2 multi-layer VBS malware samples - decoding obfuscated dropper stages and tracing the full payload delivery chain to uncover the exploited weakness and the final-stage persistence mechanism (ManageEngine UEMS RMM agent).
• Documented 5 indicators of compromise and mapped adversary TTPs against MITRE ATT&CK; attributed C2 infrastructure hosted on Chinese dynamic DNS providers to financially motivated threat activity.
• Authored a structured audit methodology and remediation playbook - covering IOC sweeping, registry forensics, and network traffic analysis - to close residual attack vectors across remaining hosts.
