Valve Just Told Me My Home Address Is in the Hands of Hackers. Here’s What They’re Not Saying.

You open an email from Valve. Subject line: Important Security Notice. Your heart drops. You scan the first sentence: “a cyberattack against our shipping partner, CEVA Logistics, in Europe.”

Your name. Your street. Your city. Your phone number. And the email address you use to log into Steam.

Your Steam account is only as secure as the shipping company Valve chose to trust. That’s not a metaphor. That’s your data—right now, in the hands of attackers who didn’t even need to break into Valve’s fortress.

I’m not here to panic you. I’m here to show you what Valve’s carefully worded email doesn’t tell you. And why this breach is a much bigger deal than a stolen mailing list.

The Part Nobody’s Talking About

Valve’s security is famously tight. They run their own store, their own OS, their own hardware pipeline. But here’s the dirty secret of modern supply chains: you can be a fortress and still get poisoned through the plumbing.

CEVA Logistics handles shipping for Valve’s hardware in Europe—Steam Decks, Index VR kits, whatever comes next. They’re not a security company. They’re a logistics company. And they got hacked.

Now the attacker has your home address, your phone number, and—crucially—the same email address you use to log into Steam. That single string of characters is your credential. It’s the key to your game library, your payment methods, your DMs, your entire digital identity on Steam.

Valve, in their notice, says this data “may have been compromised.” They recommend being vigilant. They don’t recommend changing your email. They don’t explain that this is the perfect setup for a targeted phishing attack that even a savvy user could fall for.

Why the Email Address Changes Everything

Imagine you get a message that looks like it’s from Steam Support. It references your recent purchase—a Steam Deck, delivered to your actual address. It says there’s a problem with your account. It asks you to click a link and verify your login.

You’re already nervous because you got that breach notification. You’re primed to believe something is wrong. And the attacker has all the context they need to make the message feel real.

The real high-value target in this breach isn’t your physical address or package data—it’s the email address, which doubles as a Steam credential and enables targeted account takeover and phishing attacks. Valve knows this. They didn’t say it.

This is the supply-chain risk that nobody wants to talk about: when you trust a company, you’re also trusting every vendor they touch. You didn’t choose CEVA Logistics. You didn’t consent to sharing your data with them. But your data is there anyway.

What You Need to Do Right Now

Enable two-factor authentication on your Steam account if you haven’t already. Use the Steam Guard mobile authenticator, not email-based codes. Why? Because the attacker already has your email. They could intercept a code sent there.

Consider using a unique email address for your Steam account—one that you don’t use for anything else, especially not for shopping or shipping. Yes, it’s a pain. But it isolates the damage when a partner gets hacked.

And be skeptical of any message that claims to be from Valve support. Valve will never ask for your password or your 2FA code. If they do, it’s a scam.

This breach isn’t the end of the world. But it’s a wake-up call. Your digital identity is only as strong as the weakest link in the company you trust. And that link might be a warehouse in Europe you never even knew existed.

Valve can fix their internal security. They can’t fix the fact that every external partner is a potential backdoor. So take the steps you can control. Because the next email you get might not be a warning—it might be the attack itself.
