Tactics for the 24-Hour Grind

The OSCP isn't just a technical exam; it's an endurance test. After finishing my attempt yesterday, I realized that many failures happen not because of a lack of skill, but because of poor workflow and mental burnout.

Egress and RevShells

Firewalls and egress filtering are your silent enemies. I wasted time on payloads that were actually working but were being blocked by the network.

The Move: Use common ports like 80 or 443 for everything. If a reverse shell fails on 4444, try 80 before you start rewriting your exploit. It's a simple change that saves hours of troubleshooting.

Credential Logic

Don't overcomplicate initial access. Spray common credentials on every service you find. More importantly, keep a clear loot file. A password pulled from Service A is often the key to Service B. Credential reuse is a frequent intended path, especially in the Active Directory sets.

Tooling for Sanity

• Penelope: Manual shell stabilization is a waste of time. I ran Penelope at the start and forgot about it. It accepts multiple shells on a single port and keeps them stable automatically, which is one less thing to manage when you're tired.
• SysReptor: I self-host this for reporting. When your brain is fried at hour 23, the last thing you want to do is fight with Word formatting. It handles the structure so you can just dump your notes and proof files.

Thoroughness vs. Tunneling

Be exhaustive, but know when to quit. Cover as much ground as possible, but if you've been banging your head against one path for two hours, you've hit your limit. Revert the machine, take a breath, and look for a different angle.

The Strategy of Rest

I actually took longer breaks than I spent working. Stepping away from the screen isn't "wasting time", it's where the breakthroughs happen. If you can't see the solution, you're likely just too close to the problem.

Good luck to everyone heading into the labs. Stay calm, keep eating, and remember that you've got this.
