cares Posted December 7, 2014 Share Posted December 7, 2014 I discovered a method to look up item histories (and the owner) on sites providing item histories on backpack.tf. TF2, CS:GO, and Dota 2 are supported (although the two latter aren't very useful since I haven't found any good item history sites). Keep in mind it is commonly inaccurate because nearly none of the backpacks on the third party sites are properly updated. Generally, the higher the price of the item, the higher the chance of success. First off, you want either Greasemonkey or Tampermonkey. Greasemonkey (Firefox): https://addons.mozilla.org/en-us/firefox/addon/greasemonkey/ Tampermonkey (Chrome/Opera): https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo?hl=en Next, download & install the userscript here: https://github.com/caresx/tf2-userscripts/raw/master/scm-itemhistory.user.js This is what adds the links to the item history sites. That's pretty much all. Visit the listing pages you want and it'll add the links to the item histories. Demo / screenshots: ( http://backpack.tf/item/3243753824 ) If there's any bugs, let me know. Again, from what I've seen, few items have item histories attached. Keep this in mind before trying to find someone.

I wanna be able to buy scammed hats without worrying This is mostly just to find dupes for those who care and be able to offer on some items privately, SR would never demand that users of SCM use this kind of technique. In fact, most scammed hats don't even show up in the history. Link to comment Share on other sites More sharing options...
rafiozol Posted December 7, 2014 Share Posted December 7, 2014 thanks cares, gonna test it soon Still not going to use it. I wanna be able to buy scammed hats without worrying reported --- How to prevent from being found by that method: 1. Put your hat on SCM 2. Remove it (the item will have now new ID) 3. Put it again (do it fast to prevent scanners from scan it again and therefore update item history) 4. iunno JoXu ツ, Khaos, Deku and 2 others 5 Link to comment Share on other sites More sharing options...
Heated Bread Posted December 7, 2014 Share Posted December 7, 2014 As soon as valve catches wind of this, it'll probably be patched. Without looking at the script, the exploit it is using is probably something to do with looking up people's profile pictures through steam community. From that point it would be a simple matter to just open up their backpack through backpack.tf Link to comment Share on other sites More sharing options...

In fact, most scammed hats don't even show up in the history. Just wanted to say something here. Someone will appreciate being able to check the SCM for duplicates. http://backpack.tf/vote/id/53cc191f4dd7b8487f8b4569Thank you. Link to comment Share on other sites More sharing options...

KingOfHeart Posted December 7, 2014 Share Posted December 7, 2014 No thx. I don't want to deal with this stress. I already do enough BG checking in trading. The only thing you should do, is look up the seller ID on SR. Link to comment Share on other sites More sharing options...

The only thing you should do, is look up the seller ID on SR. You can't look up their steamid, that's what was recently changed. Almost no scammed hats are in item histories, so it's not worth checking. I don't know what you're upset about. Link to comment Share on other sites More sharing options...
KingOfHeart Posted December 7, 2014 Share Posted December 7, 2014 Oh cool then. No worries then if I accidentally trade with a scammer. I was upset about the stress level about keeping my rep clean...but nothing to be upset over now Link to comment Share on other sites More sharing options...

I was upset about the stress level about keeping my rep clean...but nothing to be upset over now I don't even think this is fully intended by Steam, so in no way would SR or other sites demand you use a script/method like this to check with who you're trading. That's insane. Link to comment Share on other sites More sharing options...
Sasuke200 Posted December 7, 2014 Share Posted December 7, 2014 As soon as valve catches wind of this, it'll probably be patched. Without looking at the script, the exploit it is using is probably something to do with looking up people's profile pictures through steam community. From that point it would be a simple matter to just open up their backpack through backpack.tf The way that works is all items have item ids, now how that script works is that it parses the HTML and gets the item Id. When buying an item you buy it with the item id because there are multiple of the same items on that page. It is not really an exploit. Link to comment Share on other sites More sharing options...
E-Arkham Posted December 7, 2014 Share Posted December 7, 2014 I'm concerned that Valve will now patch this out by obfuscating the item IDs. For example, hide them behind a hash value with a server-side random seed. Hopefully hash collision due to the ridiculously large number of item IDs makes patching it like that non-trivial and more trouble than it's worth. Guess it depends on how seriously they want to gimp our ability to check histories and find owner profiles. Link to comment Share on other sites More sharing options...

Genzarata Posted December 21, 2014 Share Posted December 21, 2014 Very useful indeed, thanks a bunch. It's a shame it doesn't work on all items, but that can't be helped. I am curious though, I don't get links showing up for listed items on page 2 onwards - is this a bug on my end, or with the script? Link to comment Share on other sites More sharing options...

oap Posted April 4, 2015 Share Posted April 4, 2015 I have an alternative method I found for those of you who do not want to download any scripts: first, hover over the 'buy now' button on the item you want to find the history of: next, right click, and press "copy link address" next, paste that link address into your url bar and copy the last string of numbers in the url bar next, go to tf2outpost.com and click on any unusual listed to bring up the history. from there, click on "permalink" under the name of the unusual in the pop up next, find the second string of numbers in the url bar (which I have highlighted) and paste the string of numbers you have previously copied to replace these numbers then, press enter and you will have the history of the item you want to buy. from here, you can retrieve the owner's steam profile, their backpack, and their outpost trades hope this helps !каблам, praise, Alberny and 10 others 13 Link to comment Share on other sites More sharing options...
