Setup 2FA

One question for those that know how these things work - if you have 2FA and you sign in to one of these sites, how do they use that information to login to your account? How do they bypass steam guard?

Well,it looks good that you got your account back!

I asked one of these dudes why they keep spamming me and they actually apologized and said it was a different person the other time LOL

Yeaaaah, That is kind of a big deal in steam for a few years now.
Always check url address on your browser to make sure you are not login into a fake website.

It's great that I have no friends and no one writes to me ... yes, great
sad lonely sounds

damn just found out about it :c , i was hacked too

You didn't get hacked. You got hijacked. Those are two different things. :P
You unwittingly gave your account details to a scammer by signing into a fake page.

There is a way to avoid getting hijacked. You could check the link to make sure that you're on the right page. But, I Always make a rule of going to the actual steamcommunity link myself and log in there first before linking any website, even if it's one I think I trust. When linking, you shouldn't have to enter credentials again once you're already logged into Steam on your browser. ;)

I once fell for that many years ago, but luckily, was able to get my account back in a matter of minutes, but I remember the horrible feeling. I probably didn't have any good items or whatever he was looking for so he logged out, this was before 2FA was introduced.

But the funny thing is, I didn't fall for the classic "get free games" scams, but a friend sent me something like that, vote for favorite team or whatever it was.

Also the link had a j instead of an i in community.

I'm confused by the people saying that this person wasn't hacked.
I get why they think social engineering isn't a "real" hack, but I'd also bet that any hacker worth their salt would concede that social engineering is very much a part of real hacking.

Anyway... best of luck to you, hope Steam support can resolve it quickly, and stop clicking random links!

seems more like you gave your credentials in a plate to someone, it's more like phishing attack than hacking as far as I know. also I remember one of moderators I guess made a thread and posted a very useful YouTube video which explained all kind of scams and ways they will try to get to your account, and this method was obviously one of those, So I guess you might not looked into it or skipped it somehow!

Sorry this happened to you. I work with data security and one thing I do tell people to do when they ask how to make things more secure is to consider using a password management tool.Something that will auto-fill the password on a known website. It's very easy to tell if a website is fake, because your credentials won't be shown there. Even your browsers built in password storage is better than nothing, especially if you are using secure, unique passwords. I know with steam it's a little different because you have to type your password into the client to login, so you need to know it, but I don't know most of my passwords on websites, because I'll set them once and forget. I know some people have concerns about 'what if the password manager gets hacked', but the simple reality is that far more data breaches happen because of social engineering or insecure passwords, than because of an actual 'hack'.
And the number of people who use the same password for everything is frightening. When I give them a login with a nice secure password, the first thing they want to do is go and change it to their 'favourite' password. I nearly punched the person through the keyboard the other day when they got the new google chrome popup show up for them on our system, telling them the password they used has been involved in a data breach and they should change it. They were shouting about a data breach on the system and I was like, 'Dude, it's your damn stupid password that you've used on every site that is the problem!! Change it right now or I will lock your account'
Anyway, glad nothing too bad happened to you, never underestimate the lengths con artists will go to for access to your stuff.
