Hi all,

This morning, there was a breach due to a flaw in our item DB server configuration. As a consequence, our active item and item history tables were erased. This is used to power the stats, item history and item search sections of the website.

We have triaged the issue and can safely say no other sections have been affected.

The good news: We can restore the active item table from recent inventory snapshot data that we keep.
The bad news: It seems highly unlikely we will be able to restore item history entries.

We do not believe the attacker had anything to do with TF2 trading, and was just scanning anything vulnerable for credentials to steal or blackmail. In this case, they just decided to delete our data.

We are currently restoring the item DB as fast as we can. Due to the sheer size of the data, this will take a while.

We have spent today auditing our entire stack to prevent issues like this happening in the future.
