Fastest way to sell multiple items on the Steam market?

[kwon]

Recently a hacker was able to use all my Steam Wallet balance to buy thousands of Dota 2 items valued 0.06

I've opened a support ticket but not much help. Was just wondering, what's the fastest way to sell all these items I have? I don't want to have to sell them one by one.

Thanks

As far as I know there isn't any way to sell multiple items at once on steam.

I may be wrong.
