@Phantagasmagoria, your steam account might be compromised, have you recently entered your steam credentials on any suspicious website/service and when was the last time you changed your password?
You might be victim of the scam type described here:
https://marketplace.tf/blog/posts/YHLZOB
To test it, you could try sending some cs:go skins or keys to a friend, the trade offer will be swapped by scam bot when you are about to confirm with authenticator.
Check as well if you got any API keys attached to your account: https://steamcommunity.com/dev/apikey
Otherwise change your password as suggested in the article, it's very possible that some phishing service got a hold of your credentials.
Hi my account has no problem, I have the authenticator and I have never received mail or SMS compromising a suspicious connection.
I summarize the problem: Here I was scammed because the first bot "dispenser vault" refused the first trade for unknown reason when I request keys deposit, then they re-send a second trade offer some seconds later with their "scam bot" (who had the same profile than the dispenser vault bot)
It's not a security problem, Today I had lots of trade without any worries. It's here that there is something suspicious and dishonest
Your description is exactly like described in the article, even the part with cancelled trade, that's how the scam works. About your other trades, i guess the scam only works either for specific sites or more probably when items are only present on your side of the trade offer, then it will try to steal them by sending fake offer.
dispenser.tf is trustworthy, i and other users have been trading here for years. I don't won't rule out that it can be compromised as well, but in that case there would be many more reports like yours.
I'm still inclined to think that it's a problem on your side, some phishing website got a hold of your credentials because you entered them there and has access to your trade offers and can automatically cancel them when you are depositing items and resend you fake ones that you are confirming with authenticator. Read the article again, it's a type of a scam where you will never receive any mail or sms about anything.
