✍️ Sample OSCP Questions & Answers
1. What is a common technique to bypass file upload filters that block PHP extensions?
Using double extensions such as shell.php.jpg can bypass naive file extension checks if the server processes the PHP extension before the final jpg extension.
2. What technique allows an attacker to maintain a persistent rootkit-level backdoor without modifying disk-resident files on Linux?
Loadable kernel modules (LKMs) run in kernel space and can hide processes, files, and network connections; they can be loaded without leaving obvious file-system artifacts.
3. What type of attack involves tricking a victim into sending authenticated requests to a vulnerable web application without their knowledge?
Cross-Site Request Forgery (CSRF) forges authenticated requests from a victim's browser to perform unintended actions on a web application where they are logged in.
4. What are NTLMv2 challenge-response hashes and how are they typically cracked in OSCP?
NTLMv2 hashes are challenge-response authentication tokens captured from network traffic or via tools like Responder, and are cracked offline using hashcat module 5600 (NetNTLMv2).
5. Which PowerShell command checks whether the current user can modify a specific service's binary?
Get-Acl retrieves the security descriptor (ACL) of a file, revealing which users have read, write, or modify permissions on the service binary.
6. What does the SLEEP() function in a SQL injection payload help an attacker determine?
SLEEP() is used in time-based blind SQLi to confirm a vulnerable injection point by causing a measurable delay in the server's response.
