So some time ago my entire inventory was cleaned out. I had Dota 2 Arcanas, tons of immortals and am guessing it was about 500€ he stole from me in items. Now I have no idea how he did it. I just got a mail from Steam telling me there was a suspicious trade going on and if I did not agree to this trade I should press the cancel trade link in the mail. Did that and thought it was dealt with, until I logged in later that evening and realized that all my items got stolen.
Does anyone know how he did it and what he used for it? I still have the users account name and I would really like to get my shit back, if it isn't sold yet.
