Scam Prevention: Protecting Your Inventory from Phishing and API Exploits
Every year, thousands of traders lose their inventories to schemes that could have been stopped with a few minutes of caution. Phishing attacks remain the most common threat, typically delivered through fake marketplace links sent via Steam chat or Discord. These pages mimic legitimate platforms almost perfectly, capturing your login credentials the moment you enter them. Once attackers have access, automated bots strip your inventory before you even realize what happened. The single most effective defense is to never log in through a link someone else sent you. Type the address manually or use a bookmark you created yourself, every single time.
API key hijacking is the second major threat, and it catches even experienced traders off guard. When you sign into a third-party site, you may unknowingly authorize access to your Steam API key, which lets attackers intercept, cancel, or redirect your trades. The damage happens silently, often while you’re waiting for a trade you think is still pending. Reviewing your API key settings regularly and revoking anything you didn’t personally create closes this gap immediately. Enabling Steam Guard mobile authenticator adds a second layer that email confirmation alone cannot provide. Together, these two steps block the overwhelming majority of advanced attacks.
