 What's up YouTube? This is another video right up for this challenge Weird Logo from TJCTF, the recent capture the flag competition. Challenge Prompt is this company's logo stands in contrast of those other leading edge tech companies with its poor design and it gives us a simple link here that we can grab the address for because I'll download it and this is the image that we are working with just this weird logo. Okay so in the terminal I will W get this so I can download and work with it and then we can do some regular file analysis stuff that we've done on regular things that we've worked with before. We could use our low-hanging fruit, check out strings on this, run it through XF tool etc etc. There's not a whole lot that I'm going to see in this so I'm going to move to my next inkling and then okay this may be a steganography challenge. I want to take a look at more of this image. So what my typical go-to and other low-hanging fruit knee-jerk reaction for steganography challenges is called the tool StegSolve. So if you wanted to just simply google this you could and there are some links here, some github things that will give you an install script but really what I'm looking for is this jar itself. That install script will go ahead and download that for you if you wanted but it looks like I can just go ahead and grab the raw file here so I will do that. If I go ahead and grab this link we can download W get StegSolve.jar. Okay great so stegsolve.jar is a java archive file so we will run it with java tag jar on stegsolve and then it's this tiny window up here that I don't often see sometimes I have to use like alt space m to move it just so I can get it on my monitor and the file and the browser the menus are kind of hard to navigate so the o is a hotkey for simply opening up the open browser. So once we have it in there we can analyze this image by looking at it in different alpha planes but depending on the color the last bit of one specific color are red green or blue maybe if the image is x-word or inverted etc etc but we'll see in just the last couple bits of some colors you can see there is a flag tjctf and inplane site so I'm going to just take a note of that flag dot text tjctf it was inplane site great and then we can uh go ahead and write a solution dot text if you wanted to just noting that we are using stegsolve but just keep track of your own simple write-ups at least minimal that you can prove okay this is remind yourself this is how I solve the challenge but that is what we would submit for another five points very simple challenge on tjctf but cool good to know that secondography tool and have that in your back pocket quick and special shout out to the people that give me some love on patreon you guys are the best thank you so much I can't say it enough one dollar a month on patreon will give you a special shout out just like this at the end of every video five dollars a month on patreon will give you early access to every video that I release on youtube just before it is actually going to go live and deployed so hey if you like this kind of video ctf write-ups if you want to see more of these or more programming tutorials stuff that I do please do like comment subscribe join at our discord community link is in the description uh it's an awesome community of ctf players hackers and programmers if you're willing to uh check me out on patreon but i'll see you in the next video thanks
