Briefing
// 30-second briefing. Subject: Ogi.
I think like an attacker — so organizations, and everyday people, don't have to learn the hard way.
For 10+ years I've worked on both sides of security: penetration testing, digital forensics, SOC operations, and today Cyber Threat Intelligence in Indonesia's banking sector — hunting phishing sites, fraud networks, malicious apps and data leaks before they reach people.
The other half of my work is AI. I build Agentic AI and LLM-powered systems that automate threat intelligence, brand protection and incident response — turning hours of manual analysis into minutes.
Outside my day job I break cybersecurity and AI down for everyone: how hackers and scammers really think, and how AI can genuinely help you.

Selected operations
Autonomous Threat Intelligence & Brand Protection
Agentic AI that crawls the open web and social media for phishing sites, malicious APKs and leaked data — then escalates and drives takedowns automatically.
AI-Augmented Incident Response
LLMs integrated into SOAR playbooks to move incident response from rigid rules to context-aware, autonomous triage.
Dark Web Intelligence Crawler
Automated dark web surveillance matched to organizational keywords, unified into a single threat intelligence platform.
Credential Leak Auto-Remediation
Aggregates leaked customer and employee credentials from multiple sources and remediates them before threat actors can use them.
Financial Account Abuse Hunter
Detects bank accounts used by illegal gambling and account-trading operations on social media, then disables them.
Face Recognition for Home Security
Published research comparing face-recognition accuracy under varying lighting using Kinect imagery (EIConCIT 2021).
