Bartłomiej Biskupiak's IT and Cybersecurity Project Portfolio 🔐
Hands-on blue-team work: vulnerability management, Windows hardening, SOC-style investigations (Sentinel + Defender), OSINT/CTI volunteering and a lightweight SIEM/log parser.
- WinTriage v0.4 - lighweight PS triage script for rapid IR
- Incident Response Report (PowerShell Suspicious Web Request)
- Incident Response Report (Virtual Machine Brute Force Detection)
- Threat Hunt Report (Unauthorized TOR Usage)
- Vulnerability Management Program Implementation
- LogSniper - lightweight SIEM / log parser
- 🔭 LinTriage - Developing a Bash-based counterpart to WinTriage for rapid Linux forensic collection.
- 🧪 SC-200 Mastery - Intensive study on Microsoft Sentinel, KQL, and all the Defenders.
- 🚩 CTF Training - Participating in solo and team-based CTFs to sharpen investigation skills.
- Threat Hunt Report (Unauthorized TOR Usage)
- Incident Response Report (Virtual Machine Brute Force Detection)
- Incident Response Report (PowerShell Suspicious Web Request - Azure VM)
Built during a 24-hour national hackathon focused on fighting online disinformation and phishing targeting Polish citizens.
-
Prawda w sieci - Verifier (gov.pl URL & QR checker) Web app + backend prototype that lets a user paste a link or scan a QR code claiming to be a
gov.plpage and get a clear “trusted / expired / invalid”-style verdict.
Focus on:- server-side session / token checks instead of trusting the raw QR,
- simple validation and basic input hardening to reduce obvious abuse.
-
Prawda w sieci - Trusted gov.pl QR generator widget Small widget (gov.pl / mObywatel style) for offices to generate time-limited QR codes only for approved
gov.plURLs.
Designed to work together with the Verifier:
office generates QR → citizen scans in the app → Verifier checks the backend entry and shows whether the page is legitimate.
These were rapid prototypes built with heavy AI assistance - our focus was on the security design, threat model and user flow.
