HackTheBox - Perfection

00:00 - Introduction
00:50 - Start of nmap
02:50 - Discovering the Weighted Grade Calculator which we will exploit
04:50 - Using FFUF to enumerate all bad characters and discovering we can't send any symbols
07:10 - Quick bash one liner with JQ to URL Encode each line of our wordlist
09:30 - Discovering a New Line character breaks the search for Bad Characters, then getting a shell on the box
14:40 - Shell returned, looking at the source code and seeing the "Bad Character" filter was really a regex whitelist
18:50 - Discovering mail that says the password format in the database
21:50 - Using hashcat Bruteforce mode to crack the password

22:50 take a look at the "Using 'p' (Nth instance of a character) with positional rules" section on the Hashcat wiki page you were on (closer to the bottom of the page)

echo ippsec | hashcat --stdout -j '$_ f /_ Dp $_'

$_ = append character _ to end
f = duplicate word reversed
/_ = memorize position of first instance of _
Dp = delete character at position p
$_ = append character _ to end (again)

output is ‘ippsec_cesppi_’

I learned pen-testing largely from these videos. Three years ago, I got my first pentesting job and somehow promptly forgot all about IppSec. Until today. It's such a great feeling, to know that all my studies paid off. I can finally understand the full content of these videos! Yipee!!

[NatteeSetobol]

I didn't know you could brute force with hashcat like that. I always learn something new!!

Babe, wake up, new IppSec video dropped

[Ms.Robot.]

❤🎉 another sweet drop from the Wizard of the Matrix.

Thanks, as always your explanations are gold!

[bread_girl_jane]

ippsec you’re one of my heroes but the way you pronounce ubuntu kills me lmao

[muhammadather]

Hey ippsec. Thanks for amazing content as always. I was just curious y do you use separate machine for cracking ? Can you share specs of your "kracken" machine. Looking to build one

[Martin-Pentest]

Hey Ippsec i have a question that i guess is unrelated to this particular video but i know your the man to ask.. so i'm trying to figure out why if i type echo "password" | md5sum the output or string is totally different to the string i would get on say md5 hash generator online? Maybe i am being stupid but i guess i won't know if i don't ask.

Aside from HTB and TryHackMe, what tools should I be playing around with on my computer in order to break into Cyber? I have a few ideas: Kali Linux, Linux GUI, Windows command prompt. What else should I download?

[kvdp]

makes it look so easy. This box would take me 5h to crack probably.

[shxpr]

I assume hashcat checks file each iteration instead of remembering it's content

[ManuGram]

Really great content, i just wanna ask if you could do more mobile app hacking

[seMcln]

ffuf supports OS commands to encode input

[jhncnnr-sec]

Hard to tell he ever had a speech impediment now

[raphaelriera-vb]

hey my burpsuite browser can't connect to the website

[_Mann_Kasodariya]

can you make video about how can you have option to which search engines do waan search for it or give me name of softwer so i can to. if anyone know in chat will you help me into this 3>.

Hey Ippsec, yesterday I got a new VIP sub for HackTheBox for a year. Haven't done any of the Sherlocks earlier until today. I really liked the LockPick3 Sherlock! Have you done that one yourself already ?
