HSCTF - Hidden UTF-8 Encoding (Real Reversal)

[infiniti]

Never knew about rev until now. Thank you!

Real appreciate you making these HSCTF make them look so easy !!!

Another great video. I'm not sure how you keep up with ctf's, work, and find time for the videos and explanation, but keep up the good work.

If you were to treat the file as binary data in any language a reversal by loop would work fine.
The only issue with your python3 is you didn't open the file in BINARY mode!

Solve: reverse binary 》 decode utf-8 》 normalise utf8 to latin-1 compatable characters 》 reverse Text 》 grep flag prefix.

Love your channel. Been a part of this and the JHdiscord community for about 6 months now. You legit make learning fun. I made some contributions/PRs on the ctf-katana repo would love if you could check them out! also can you do some vulnhub machine's writeups, prolly machine's that are suitable for beginners starting with vulnhub/HTB ? I just love the way you solve a challenge, it's not just about capturing the flag, but so intuitive!

I just noticed something (aside from this video being super old).
When John first showed the weird binary data, the first thing that popped out were the random characters in places. I don't they are just random/coincidental bytes...
Look at 5:27, at around the center of the binary text data thing, you can actually see parts of the flag. ({, }, _)

In py3 you can use bytes instead of string. Py3 bytes == Py 2 str

Hi can you make a guidance for hack the box before you put the solution

[mohamedabdou]

Great job. However, you mistakenly blamed python3 for not reading it right :P
In fact you should have specified an encoding method as a param while opening the file such as: open("reversed.txt", encoding="utf-8")

[danieleperera]

can you make an ENCODER for this challenge ?

[NethTech]

I like how you named the python script reverser yet didn't bother reversing the txt via python instead opting for piping to rev lol

Please do Verbose in Miscellaneous hsctf Brain f**k char

around 2:11 if u read it from the end reversed, then u can read

Wow this is

and if u skip and go to a part which looks like a ctf flag and then type it reversed then u get the answer
