There May Be Truly "Fake" or "Spoofed" items

In a video I came across the other day, DooM appears to show a couple suspected hackers providing his evidence at the beginning of the video. He then shows one of them change his skin mid-game without leaving the match in an uncut segment. I do believe it's impossible to change your skin midmatch, but perhaps there is an exploit or like one of DooM's viewers suggested, perhaps they are sending packets with false information to the server. Otherwise I don't know how this player did what he/she did.

Skip to 7:06 to see the skin change with explanation

He's talking about "verification" of items....

To clarify: I am not saying you should believe scammers who claim your items may ne duplicated, glitches, bugged, Ect.

I don't know what this player was doing. I can see he changed his weapon skin mid-game without leave in a competitive match.

I've seen that video before, your inventory is disabled in matchmaking, you can't access it to change your equipments while in-game, however DooM is claiming that he's scamming, manipulating items and using exploits to scam others depending on just the fact that he changed his knife while in game, which is a pretty useless and ignorant claim

There isn't any evidence of the player scamming anyone, but if the player is able to change his skins mid-game and the skins are not truly owned by the player, then there's plenty of potential to scam. However to say that scamming is absolutely happening isn't true either.

@Lava Understood. Thanks for clarifying.

worth noting that the suspect owns both knives in his inventory, I believe he just foubd a way to access his inventory mid game, nothing else

I suppose unless someone finds evidence otherwise, the items are genuine, however the switching is abnormal and could be the result of cheating or exploiting.

Thanks for the input guys and for taking the topic seriously as well as without hostility.

We're not hostile for honest discussion, which this is. Only to obnoxious idiots who don't read, misquote, false accusations against people etc.
You come with an honest (semi-related) trade issue, and kept talking on point, and people chimed in. That's what this board is for, and nobody will be hostile or w/e, and if, then those are in the wrong.

On point, I'm not a CS:GO player, so don't know specifics on the "possibilities" in matches etc for changing items / skins etc. What I DO know, is that if you record a demo in TF2, you can edit the demo to change things and then replay it. You have to know the format and know how to etc, but I do know it is possible.
If you replace for example a rocket launcher for a shotgun, in the play it will still be a rocket that's been fired, and see a rocket fly and not the bullet spread etc.
The difference of one knife to another? you won't notice any difference.

Also, you can record from both the original demo and the edited one and make a cut that won't be noticeable, as long as for both the same frame rate was used in the same resolution.

I'd suppose the ID code for the knife is easy replaceable in the recorded demo.....

That's my educated guess for this, maybe he used some program to make his game believe so, no idea, but that would be risking his items with VAC....

I see the last reply on this post was somewhat old, but I have come across a person who changed some code around in the game and made a downloadable program that will let you access your inventory while alive in competitive matchmaking. Googling LoadoutEnabler will bring up the page about the program and also have another link to another code for the source code for the exploit.

I'm not sure if this exploit still works or not but I hope it clears up some confusion about the "packets" thing. All of the items in his inventory were owned by the player him/herself and may have or may not have been acquired through scamming.
