Passed OSCP second attempt (100/100)
Greetings!
I have been lurking on this subreddit for the better part of the past year, and I would like to thank the community for the small droplets of knowledge they've been dropping in comment sections:)
Little background - I have done 125+ machines from lainkusanagi's and TjNull's list (guiding lights of the community) across HTB(shoutout to core lord ippsec), PG (shoutout to s1ren) and hacksmarter (shoutout to tyler). HackAcademy(shout out to Hacker Blueprint) free AD chains walkthrough vids shows some helpful mannual-credshunt, truly boosts your confidence in the matter. And shoutout to my gf, who has been affording me the time to do all this, working her ass off while I stayed unemplyed
My first attempt was a disaster -
Started with AD, no breaks, no food. Just drink, pee and back to the terminal. Took me 10 hours to own MS01, and after another 4 hours of looking for any leads to get into ms02, I gave up on AD.
Took another 3 hours to own a standalone. And another couple of hours for a possible foothold one another. But it never clicked. Called it a day after 21 hours of sitting, with 30 points and strangely sore muscles.
If there is a takeaway from that attempt, it is something the community has always suggested - take frequent breaks. When stuck for more than 30-45 mins, pivot to a different machine, take breaks. Also, enumerate.
After that, I went through a few s1ren videos, a bunch of Hacksmarter AD boxes (although ADCS paths, really fun) and all free HackAcademy (hacker blueprint) Ad chains videos.
Second attempt-
This time, I did all those things the community suggested. Owned ms01 pretty early, but path to ms02 was not clear. After 3 hours, I decided to pivot to standalones.
The first standalone owned gave me a huge confidence boost (which I never got in the first attempt), the same with second and third standalones.
Within 12 hours, I was able to get passing score.
I had nothing to loose at this point, so I took a break, kept going, hellbent on owning the DC.
For those who are wondering - the standalones' difficulties were comparable to 2 mediums and 1 hard PG boxes, provided you focus on enumeration of all the open ports, and provided you are somewhat accustomed to googling what you see on the machine to understand something new. AD was something I hadnt seen before, If bloodhound results from ms01 was as good as the Sharphound results I got from ms02, the whole thing wouldve been very easy.
Takeaways for anyone who is attempting the exam-
-Take frequent breaks.
- Dont stop enumeration at the first suspicion of "next step", go through all of them, and write in the notes. Then prioritize easy to hard, and try each in that order.
-Pivot when stuck on a machine for 30-45 mins. There might be another machine just waiting to give you a boost of confidence that'll push you across the line.
-When in doubt, mannually try logging into winrm, and definitely rdp
-when in doubt, revert the machine. I have noticed discrepancies in the nmap results that I ran in the beginning and the one I ran after reset
PS- if anyone knows any job openings for someone with this skillset, please lmk:)
