Exam Day Strategies

The final challenge isn’t just technical—it’s a marathon of endurance and strategy. Proper planning transforms those 24 hours from chaotic scrambling to controlled execution. We’ll break down the timeline, attack prioritization, and documentation essentials.

24-Hour Exam Breakdown

Divide your exam into three strategic phases:

• First 4 hours: Comprehensive reconnaissance on all machines. Document every open port and service.
• Next 4 hours: Focused attacks on the Active Directory set (40 points) and highest-value standalone targets.
• Final 16 hours: Privilege escalation and meticulous reporting. Leave buffer time for unexpected hurdles.

Prioritize the AD set first—it’s mandatory for passing. Then tackle 25-point standalones before lower-value machines.

Time Management During the Exam

Set hard stop times for each phase. If you haven’t rooted a machine in 90 minutes:

1. Document current findings
2. Switch targets
3. Circle back later

Metasploit has strict usage limits—save your one allowed module for critical moments. Most veterans complete all exploitation within 12-14 hours, reserving 10+ hours for reporting.

Note-Taking and Reporting

Your report accounts for 20% of the score. Follow this structure:

• Methodology: Explain your systematic approach
• Exploitation Steps: Detailed commands with timestamps
• Proof: Screenshots showing user.txt and proof.txt contents

Use tools like AutoRecon to automate evidence collection during the exam. Document every failed attempt—they demonstrate thoroughness.

Common Pitfalls and How to Avoid Them

Many candidates stumble into predictable traps during their OSCP journey. Recognizing these patterns early prevents wasted effort and frustration. We’ll examine two critical areas where test-takers frequently falter.

Over-Reliance on Tools

Automation crutches become liabilities in the isolated exam environment. Offensive Security bans several popular tools to force manual techniques. The prohibited list includes:

• AutoRecon (automated enumeration)
• SQLmap (SQL injection automation)
• Any mass vulnerability scanners

Web applications demand hands-on exploitation. Practice manual SQLi with:

1. Identifying injection points via error messages
2. Crafting UNION-based payloads
3. Extracting schema information step-by-step

Underestimating Privilege Escalation

Privilege escalation separates passing candidates from strugglers. Windows and Linux systems require different approaches to gain administrative access.

Windows vectors often overlooked:

• Unquoted service paths with spaces
• Token impersonation vulnerabilities
• Misconfigured registry permissions

Linux escalation pathways include:

• SUID/GUID misconfigurations
• Cron job hijacking
• Kernel exploits (last resort)

Use checklists like LinPEAS/WinPEAS to systematize your privilege escalation methodology. These scripts highlight potential vulnerabilities without violating exam rules.

Building deep system knowledge proves more valuable than tool mastery. Understand why vulnerabilities exist, not just how to exploit them.

Final Tips for OSCP Success

The last stretch before your certification attempt requires both sharp skills and smart habits. Beyond technical prowess, your mindset and routines will determine whether you cross the finish line. Let’s explore how to optimize your final preparations.

Mental and Physical Preparation

Treat the 24-hour test like an athletic event. Sleep deprivation and poor nutrition sabotage performance. Follow these strategies:

• Pre-exam rituals: Customize your Kali setup with essential tools and bookmarks. Verify all dependencies work offline.
• Energy management: Schedule 5-minute breaks every 90 minutes. Stretch, hydrate, or do quick push-ups.
• Meal planning: Prep high-protein snacks and electrolyte drinks. Avoid sugar crashes during critical hours.

Veterans swear by mock exams under real conditions. Simulate the full 24-hour experience, including report writing. This builds stamina and reveals workflow gaps.

Last-Minute Review Techniques

Final-week prep should focus on reinforcement, not new material. Prioritize:

• Cheat sheets: Print command references for Windows/Linux privilege escalation and common web exploits.
• Tool compilation: Organize scripts and one-liners in categorized folders for quick access.
• Reporting pitfalls: Triple-check that proof.txt screenshots include timestamps and clear system identifiers.

“Hacking is supposed to be fun—if you’re not enjoying the process, you’re doing it wrong.”

Approach the test with curiosity rather than fear. Every obstacle is just another system waiting to be understood. With disciplined breaks and strategic reviews, you’ll maximize your chances of success.
