Thanks SAgnihotri - Problem is I don’t watch a lot of TV. :frowning:

If only I had a way to watch TV, my scan lines are too slow. :crying_cat_face:

Can someone please help me? I have the flag but it came out lets say hard to read and it is not being accepted.

Hi Mtitter,

I had also some troubles with the reading of the file.

I just tried and tried and found out that the i, l & 1 are kind the same in picture.

To help you, HTB{xlxx-xxxx_xxlxx1x1xx_xxx_xxx1x_xxxxxx}

The l is a lowcap (ell) L

I hope this helps you and others.

Kind regards,

Tom
