Someone bought an item off the marketplace on my account without being on my account???
I'm gonna type a whole lot to explain the entire situation.

I woke up this morning and logged on steam, I originally had about like 5 bucks on my funds but it was 49 cents when I checked today. I didn't recall buying anything at all, so I checked my purchase history and it said I had bought some DOTA thing off the marketplace for $4.49 when it's actually only worth about 5 cents. I checked my email and it said the purchase took place Monday, September 8th at 8:11 AM.

Before anybody says I probably bought it and forgot or smth, I literally don't even have DOTA in my library and wouldn't stupidly pay 5 bucks for something that's worth 5 cents. Thing is, it doesn't seem like whoever bought it logged on at all? I set up 2FA and Mobile Steam, so I would for sure get notified if someone were to try and access my account, but I don't have any notifications about them.

I don't know if anyone else has had t his happen to them, as I can't find any discussions or solutions to this problem, let alone a cause. Is this some new scam going around or something? Is it possible to be refunded for this? The account I bought off seems to also be a CS:GO Exploiter with no VAAC ban, at least according to the profile comments.

I reset my steam account password in case somebody were to be in my account, but I'm still suspicious if maybe that wasn't enough. A note to add is that it doesn't seem like whoever was on my account didn't sell anything very important on my account, only some scrap skin on CS:GO that's worth a couple cents. Hopefully, I don't wake up the next morning with my knife gone.

I've also been getting lots of scams who hit me up for my knife, but I don't click on any links they send or anything and just ignore them. Either way, the person I bought off wasn't anyone who messaged me either.

Sorry for typing a ♥♥♥♥♥♥♥♥ essay, but I'm genuinely confused and concerned for the safety of my account. If somebody could help me out with this, I would be greatly in your debt.

That would probably be the highest probability, as I log onto CS:GO Marketplaces often such as cs.money and more to check prices of skins. I must've logged onto a suspicious site without warning a while back. Thanks for the input, I wouldn't have came to this solution if I'm being honest.
Those are the main culprits usually and that 'money' site is also embroiled in phishing so I would avoid that in future.

The fact less that $5 was lost shows the scammers were amateurs because most sites will only act on an account they've compromised if they payoff is significant. Some will only intercept trades that have a 3-figure value and others wont launder through the market unless it's over $20. They know once they've acted, their cover is blown so to swipe only $4.49 minus fees is pretty lame and desperate.

Doing the steps has made your account completely secure going forward but the next time you give away your credentials to one of these sites then you'll end up getting shadow-hijacked again and you wont know until it's too late. Next time it could be for a much more significant sum.


I just got scammed today i sold my doppler for 330euros went outside to the shop for literlly 10 mins came back to look to buy a new game with the money i had and it was all gone... no notifications no nothing so i lost all 312 euros... im acc so pissed

first thing to do is see if it was a hiccup, seeing as how it ahppened so fast

restart steam, and see if that does anything

if not, do what the first post

your account is compromised
DO NOT TRADE


Steps to take NOW:
1. Scan for malware https://www.malwarebytes.com/
2. Deauthorize all other devices https://store.steampowered.com/twofactor/manage
3. Change passwords from a clean computer
4. Generate new backup codes for your Mobile App https://store.steampowered.com/twofactor/manage
5. Revoke the API key https://steamcommunity.com/dev/apikey (there should be nothing in the APIKEY)

after you secure the account, figure out now you gave away the log in

suggests and make sure that you account is clean

Your transaction/market history should trace where any funds went.

Yes, you leaked your information somewhere. There's no other way for hijackers to access your account.

And no, Support will not give you back any money spent on the market, and they will not restore any items that were stolen.

You can close that ticket, you are wasting Supports time and the time of everyone who actually has need of Support.

I got something similar happen to me. I saw this today but I "bought" this 4 days ago; Ascendant Phantom Lancer Loading Screen. For much more than it's worth.

It just took 14 PHP but that still means that my account is no longer safe :C

follow the steps that have been posted in this thread to secure your account. make sure you follow them exactly and carefully

Same thing that OP wrote happened to me today. Woke up with a purchase i never made, but it actually was a good price for the item, so i aint even mad. Why would someone hack my account and then buy something for a good price?

So i didnt lose anything, ofc i did everything suggested here already. Also yes, i used third party marketplaces before and gave them my api key, namely ♥♥♥♥♥♥♥ and buff163. I always logged in through steam though, never entered my info anywhere other than steam.
So can someone explain again please how these people logged into my account without needing to authenticate through steam guard (which still works btw)? Even if i try to login on a new device using correct credentials i have to confirm the login with steam guard.
Also i never entered my password anywhere other than steam, and logging in through steam should be safe regardless of the site, since you never share your login info with them directly.
Btw im a web developer so i know generally how this stuff works, even though unfortunately nobody is immune to being hacked/phished.
I would really want to find out how this happened and where my credentials got leaked, if they did. Unfortunately it seems i cant check who logged into my steam account during the time the purchase was made, seems like a feature that should be available. Or is it and im just missing it?

Steam accounts hijacked not hacked and clearly you did login on one of those sites. You might not usually but you did at least once.

Steam Guard is just another key. If you give a stranger the keys they have access just like if you gave a stranger you house keys

Once you login to a phishing site they don't log out

Can't check who logged in at the time???
1. They could have been in for hours, days or weeks
2. As far as Steam is concerned they are YOU as only you and Steam should know and have access to the account security credentials

So how exactly is Steam supposed to know someone else has access to an account?

"Steam accounts hijacked not hacked and clearly you did login on one of those sites. You might not usually but you did at least once."

Yes, if you read carefully what i wrote, i said that i use third party trading websites regularly.
I understand what you are saying, but i know the difference between a phishing site that asks for username, password and authenticator code and a "login through steam" button where you provide none of that.
If anyone wants to see an example of a phishing site and how it works, this video explains it very well: https://www.youtube.com/watch?v=EElGnqNZdBc&t=50s The timestamp shows what that would look like.
Cant see myself falling for that.

"Can't check who logged in at the time???"
Sorry, i meant to say "who WAS logged in at the time".
You know, a List of all logged in devices for example.

"So how exactly is Steam supposed to know someone else has access to an account?"

Well if someone is logged in simultaneously from multiple locations for long periods of time, you could have systems in place that recognise that this account has possibly been compromised and warn the user, plus require them to reauthenticate through steam guard, that would essentially solve that problem. This is just off of the top of my head, im sure there are more sophisticated solutions.
Guby 2023 年 5 月 9 日 上午 8:19 
Also, requiring steam guard confirmation for purchases from the community market would make this scam method impossible, but there is as far as i know no setting for that. You could have that as default and give people the option to disable it at their own peril. Seems like im not the first one to have this idea:

I know the difference but it only takes a innocent mistake, tired, stressed, distracted or any other reason. Thus why I said you must have at some point

As for the who/what Logged in the best you can do is

Help > support >Data related to account > Login history
https://help.steampowered.com/en/accountdata/SteamLoginHistory

Multiple devices logged in not really a deciding factor you have remote play, mobile apps, home could be downloading while logged in at a friends and so on

As for confirmation for purchases Hell NO!

Shouldn't need the bloody authenticator and confirmation for trading and selling. More than enough security. I'm sick of having to jump through all the added hoops
Guby 2023 年 5 月 9 日 下午 5:55 
Thats why i said "You could have that as default and give people the option to disable it at their own peril." So it would be your choice. No disadvantage for you, so i dont see your point.

And this take "shouldnt need authenticator and confirmation for trading", thats ridiculous. We are not talking about a couple cases here, many people have inventories and items literally worth six figures. 2FA is absolutely necessary for trading, because like steam said, all transactions are final.

BTW i just found out im just stupid, but at least i didnt get phished. It was an old buy order from months ago that i completely forgot about and that was still in place, so nevermind lol

For me for example something like that happened and nobody was logged in when that happened. In fact, i dont even have API key or didnt even enter any 3rd party sites.
IMG of login history: https://imgur.com/a/Y3f3tTn
As you can see i log off and when i logged in i didnt had the items, not even 1 notificacion, nothing. They don't need access to your account. I think it's a problem with Steam Security

To my surprise, it turned out that someone had sold 120 items on the Steam marketplace on June 2 and bought items that normally cost $0.04 to things like $8.
To my surprise (Many surprises) none of the 120 items have been authorized by my mobile Steam app. Which makes me wonder. Is it safe or does it help to have Steamguard?

In my Login history there are none on June 2, nor are there any that are not from my computer.
I have not received any notification to my Email, mobile phone or Steam Guard app.
None of the sales or purchases have been notified to my mobile application (Yes to my email, but only notifications, in no case has it been a purchase confirmation.
He never accessed any 3rd party page that asked me to log in with Steam and/or gave my API key to anyone or anything like that (I don't even have one).

With all this evidence on my account (And if anyone needs a screenshot I'm happy to provide) I've decided against it. Steam Guard is not secure. What's more, it might be even safer to have it disabled and have market transactions require if or if they stay frozen on the account for 15 days instead of being accepted instantly without needing SteamGuard.

And now the question comes: What is the solution that Steam gives me?

Response i had so far: None. Steam is not responsible for market transactions and since my account has not been "Breached" because there is no login attempt on June 2 nor is there any suspicious activity (Except for the fact that I have done 120 market trades with my account closed, no notification anywhere between 2am and 6am) there is nothing that can be done and no compensation for the items I have lost.

TL;DR: The Steam Guard app and 2-Step Verification is useless. In fact it is safer to have it disabled. There is no use not logging into 3rd party accounts. Good luck everyone because it seems that there is a backdoor or day 0 error that Steam does not know about and I hope it does not happen to you!.

IMG of the transactions: https://imgur.com/a/9lzSviw
IMG of login history: https://imgur.com/a/Y3f3tTn

I scanned my PC, no malware found.
i NEVER login in to 3rd party sites, because i never needed it.
I checked my login history till 2021 (The login history ends there) and no one login in to my account other than me.

This is not a "Account compromised". Is a real security breach on steam side.

I even checked on my Gmail for confirmation or notifications from Steam. Nothing.
Changed my password, checked everything, but that doesnt mean this will not happen again, nobody is actually safe.

An account hijacker can stay logged in to your account for a long time.
On the login form is a checkbox, that tells steam to remember your login on this computer.
Just like you can do that, so can the hijacker.

So you need to check your login history longer back in time.

About how someone managed to login:

Did someone message you, asking you to "Vote for my team" or similar, with a link to "Steam"?
Or did someone invite you to a tournament, with a link to "steam"?

If it asked for your username/password/steamguard code you would think you logged into steam, while in reality it was a fake designed to steal your account.
