Security & Reverse Engineering
Information security specialist: pentesting, reverse engineering with Frida/JADX, Linux hardening, banking APK analysis, exploit development and incident response.
Information security is my core area of expertise. I work in both offensive security (pentesting, exploit dev, banking app reverse engineering) and defensive (server hardening, WAF, firewall, IDS/IPS and incident response).
Frameworks & Tools
Real Projects
Protected Banking App Analysis
Breaking 9 protection layers in a banking app: encrypted DEX, JNI dispatch with 148 overloads, TEA-like cipher and anti-fraud bypass.
International Banking App Analysis
Reverse engineering of European banking app with SSL interception, Frida hooks and OAuth 2.0 protocol analysis.
Linux Production Hardening
14 hardening layers applied to real production servers: SSH, fail2ban, UFW, kernel sysctl, auditd, systemd sandboxing.
Scanning Tools
Web vulnerability scanners, SMTP testers, credential extractors and SSH brute-force tools.
Banking SDK with Crypto
RSA/AES cryptography in financial SDKs with device fingerprint and multi-step auth.
Highlights
- Reverse engineering banking apps with multiple protection layers
- 14 layers of Linux hardening in production
- Exploit development and offensive tools
- Cryptographic protocol and OAuth 2.0 analysis
- WAF, IDS/IPS implementation and incident response
