ls ./investigations
Optional navigation. Type help for available commands.
Documented blue team training labs exploring attacker activity through security logs, network traffic, and memory artifacts.
SIEM log investigation · Training lab
I used Splunk to investigate suspicious activity against a web application, tracing reconnaissance, authorization-bypass indicators, reverse-shell attempts, and SSH authentication activity.
Evidence: SIEM logs and the lab web application.
Tool: Splunk.
Network and memory investigation · Training lab
I examined network traffic, a Windows memory image, and a recovered executable to trace an IIS server intrusion, identify a web shell and a suspicious startup executable, and review malware intelligence.
Evidence: Packet capture, memory image, and malware sample.
Tools: Wireshark, Volatility 3, and VirusTotal.
Network traffic investigation · Training lab
I analyzed TCP and HTTP traffic in Wireshark to trace port scanning, web enumeration, a web-shell upload, and command-execution activity, identifying indicators at each stage.
Evidence: Packet capture.
Tool: Wireshark.
Tool: Wireshark
Tool: Splunk
Tool: Volatility 3
Tool: VirusTotal
Programming: Python, PHP, Java, and C.

I’m Lance Joseph De Vera, a Computer Science student at Universidad de Dagupan and a CTF competitor focused on digital forensics and blue team operations. As a member of Cyberowls, the university’s cybersecurity varsity, I develop my investigative skills through competitions and hands-on labs involving network traffic, security logs, and memory analysis. This portfolio brings together my investigations, technical projects, and achievements as I continue exploring how attacks unfold and how defenders uncover them.
