OffSec shifted from static PDFs to a dynamic, live learning library. If you are looking to advance your career
The updated curriculum shifts focus from basic web flaws to complex white-box source code analysis. You must find vulnerabilities by reading code and exploiting them externally.
You might find a local file read vulnerability, use it to steal an encryption key, forge an administrative session token, and then use administrative privileges to trigger an insecure deserialization flaw that grants Remote Code Execution (RCE). 3. Exploit Automation with Python
