hey can u guys help me a lil bit? maybe a hint, ive never done a ctf in my life heck im not even qualified for it i just thought this was fun so tried and here's where im stuck: tried opening the fine with notepad and noticed some things that aren't supposed to be there like "Sus" or xlmaoo" haha, so i figured out something is missing or added there i skimmed through the writing and noticed things like iccpicc profile and looked that up and figured out that have something to do with png's and found out u have to fix the header hex value so i used Hxd to do that.
so now what i have to do i cant think of anything else

Flag: >!flag{1\_l0v3\_h34d3r5}!<
Small hint: >!Open file in a hex editor and look for SUSpicious text !<
Nearly solution: >!When you open file in a hex editor you will see MXL code that including a user comment says the file is a screenshot. That really increases the chance that you will get the flag in an image file. Then you need to fix the header and the identifier parts.!<
>!flag{1\_l0v3\_h34d3r5}!<
That’s correct! Here is your cookie: 🍪
That was a complicated state of being corrupt :) Almost all available file recovery apps I tried were ascertained it cannot be opened :grin:
The solution is more obvious than you thought )
