Hands-on hardware security: finding UART root shells on embedded devices, reading NAND flash with flashrom, extracting firmware with binwalk, analyzing for hardcoded credentials, and JTAG debugging.
Learn proactive threat hunting using MITRE ATT&CK framework. Hunt for living-off-the-land attacks, credential dumping, and lateral movement using Sigma rules, Velociraptor VQL, and Wazuh.
Cryptography demystified: Caesar to AES, ECB mode failures, RSA key pairs, why bcrypt beats SHA-256 for passwords, TLS handshake walkthrough, and common implementation mistakes that break real systems.
Essential cryptography knowledge for security practitioners: hashing vs encryption, password storage with bcrypt/Argon2, AES-GCM, TLS internals, digital signatures, and the most common crypto implementation mistakes.
Real-world cloud security failures in AWS, Azure, and GCP: open S3 buckets, leaked IAM keys, overpermissioned roles, Capital One breach analysis, and tools (Prowler, ScoutSuite, Pacu) to find issues before attackers do.
Complete beginner guide to malware reverse engineering: setting up FlareVM safely, static analysis with strings and PE headers, dynamic analysis with Cuckoo Sandbox, and code analysis with Ghidra.
Learn malware analysis from scratch: static analysis with strings and PE imports, Ghidra decompilation walkthrough, dynamic analysis with Process Monitor and x64dbg, and the best free practice resources.
The most dangerous cloud security misconfigurations in AWS, Azure, and GCP with real detection commands and remediation steps. Exposed S3 buckets, IMDS exploitation, IAM privilege escalation, and more.
