How Web Hackers Make BIG MONEY: Remote Code Execution

Show how sql injection evolves into remote code execution by installing a backdoor and redirecting exploit output to a file containing attacker data, followed by a practical demo.

The lecture demonstrates moving from SQL injection to remote code execution on a vulnerable online shopping platform, revealing a practical backdoor and proof of concept commands.

Understand how disclosure of software versions in response headers can lead to remote code execution and how attackers use exploit databases to find and launch exploits, demonstrated step by step.

Explore how disclosed software versions in response headers enable remote code execution through traffic analysis with a proxy to uncover exploits.

explain how remote code execution can occur through file uploads by tricking image files and handler configurations. compare set handler and add handler behavior and highlight risks in default config.

This demo shows remote code execution via file upload, highlighting how at handler vs set handler affects execution; includes Apache restart and warns that extension whitelists do not prevent it.

Explains remote code execution via deserialization and demonstrates a malicious serialized object triggering a reverse shell in Java using a beans decoder and Groovy shell.

Demonstrate remote code execution via Java deserialization by intercepting and replacing a serialized object in a web request, encoding it with base64, and triggering a reverse shell.

Explore how remote code execution lets attackers take full control of vulnerable machines, and learn common attack vectors—from file writes and backdoors to serialization and reverse shells—driving five-digit bug bounties.
