A Telco Security Researcher and Embedded System Developer with over 10 years of experience in telecommunication protocol analysis, embedded system design, and cybersecurity research. Founder and principal researcher at NOZ Berkarya Indonesia, focusing on emerging network security, OpenBTS/Osmocom stack integration, and SIEM for Telco networks. Specialized in combining radio frequency analysis, reverse engineering, and real network behavior modeling to improve detection, response, and resilience in telecom infrastructures (2G–5G). Committed to advancing Sustainable Development Goal (SDG) 9: Industry, Innovation, and Infrastructure, by fostering innovation and resilient digital infrastructure through open-source research and secure communication technologies.These are some of the results of my research that I have published.1. 2 Januari 2015 - Publication of research result at Infosec Institute with title “Introduction to RFID Security” At this research we do Reverse Engineering at ticket commuter line and make a attack scenario RFID 2. Januari 2015 - Research RFID – Berdikari Standalone RFID Reader dan Emulator At this research we do a design PCB use ATmega328P to be Reader and Emulator to do cloning RFID Tag. • Deep learning microcontroller • Emulate RFID Tag • RFID cloning more than 3 tags in 1 Device 3. 12 Februari 2015 - Publication of research result at Infosec Institute with title “Introduction to Smartcard Security”At this research we learn about communication of protocol used on Smartcard EMV Debit Card and 4G Provider BOLT and implement several attack • Deep learning about SIM Card • Smartcard Architecture • simulated attack identification ◦ Physical attack: Reverse engineering, Smartcard cloning ◦ Remote attack: IMSI catcher, OTA 4. 19 Maret 2015 - Publication of research result at Infosec Institute with title “Introduction to GSM security” At this research we learn about communication of protocol used on Handphone and BTS (base transceiver station). We do analysis using radio (Universal Software Radio Peripheral) to know type of encription used and tracking handphone location used LAC and Cell ID. • Analisys 2G GSM Protocol • Tracking IMSI in your area 5. 9 Juni 2015 - Publication of research result at Infosec Institute with title “Reverse Engineering of Embedded Devices”At this research we learn about how to work “broadcasters livestream” with identify all CHIP used and learning about protocol communication used, we do Reverse Engineering using Bus Pirate and Saleae Logic Analyzer. • Device disassembly and PCB design analysis. • Debugging Communication Protocol 1-Wire, UART, I2C, SPI, JTAG. • Analyze the logic signals, capture sampling and decode protocol. • extracting the firmware. • Mapping the component Device and protocol used 6. Maret 2016 - Publication Mini Course of INFOSEC INSTITUTE with title “Advanced Pentesting Techniques with Metasploit” • AUXILIARY — Scanners (Intermediate → Advanced). Mastery of additional modules for discovery, fingerprinting, and brute force against services • AUXILIARY — Fuzzers (Intermediate). Find crashes/vulnerabilities in services through Metasploit's built-in fuzzing • Credential Harvesting & Social-Engineering (Intermediate → Advanced). Technique to retrieve credentials from endpoints via post-exploit modules. • Post-Exploitation — Privilege Escalation (Advanced). • Post-Exploitation — Lateral Movement & Persistence (Advanced). • IE Proxy PAC / Proxy Abuse (Attack on Browsing Infrastructure) (Advanced). • Misc: NOP generator & Encoders (Exploit robustness / Evasion) (Advanced). • Advanced module/payload configuration & custom Metasploit modules (Expert) 7. Desember 2018 - Research and manufacture of post-disaster telecomunication equipment. Post-disaster telecommunications equipment (portable BTS / emergency comms kit) aims to provide emergency voice/data services when commercial infrastructure is damaged. This solution involves the design of radio equipment (small/portable BTS), a standalone power system, backhaul options (satellite / microwave / cellular fallback), antenna and RF tuning, signal security, and field operations and logistics procedures.8. 24 Agustus 2019 - Publication of research result at Infosec Institute with title “Mobile Phone Tracking”At the research we learning about protocol communication between Mobile Phone and BTS (base transceiver station) working, with identification LAC , Cell ID and Timing advance (TA) we could to know where the signaling come from. 9. September 2025 – SIEM Telco Research at the research we make a idea inovasion combination of OpenBTS , Osmocom Stack , and ella-core to build a telco-aware SIEM pipeline, benefit for analysis behavior endpoint and cell realtime for detection response, low level kernel analysis behavior realtime detection response, fraud detection realtime.
