Hey there, crypto enthusiasts! If you’re using Firefox and managing your digital assets with wallets like MetaMask or Coinbase Wallet, you need to pay attention. A recent revelation from security company Koi has uncovered a sneaky campaign called FoxyWallet, where over 40 fake cryptocurrency wallet extensions have infiltrated the official Firefox Add-ons store. Let’s dive into what’s happening and how you can keep your funds safe.

What’s the FoxyWallet Scam All About?

The folks at Koi Security dropped a bombshell on July 3, 2025, via a post on X by user im23pds. They discovered that these malicious extensions are designed to look like legit tools from popular wallets such as MetaMask, Coinbase Wallet, and others. The twist? These fakes are packed with hidden code that listens for your private info—like your seed phrases or mnemonic codes—and sends it straight to the attackers’ servers.

Imagine logging into what you think is your MetaMask extension, only to have your wallet drained without a trace. That’s the risk here, and it’s a growing concern in the crypto world. The post links to a detailed report (FoxyWallet: 40+ Malicious Firefox Extensions Exposed), which dives deeper into the technical side of this threat.

How Do These Malicious Extensions Work?

These rogue extensions are crafty. They mimic the look and feel of trusted wallet add-ons, tricking users into installing them. Once installed, they use event listener scripts to capture sensitive data. A seed phrase, for those unfamiliar, is like the master key to your crypto wallet—if someone gets it, they can access all your funds. The stolen data is then quietly transmitted to the attackers, leaving you none the wiser until your wallet’s empty.

This isn’t a small-scale prank either. According to recent reports from BleepingComputer and DarkReading, this type of attack is part of a broader trend. Last year alone, cybercriminals siphoned off $494 million from over 300,000 wallet addresses using similar tactics. The FoxyWallet campaign is just the latest chapter in this ongoing battle.

Mozilla’s Response and Your Defense Strategy

Good news: Mozilla isn’t sitting idly by. They’ve rolled out an early detection system to spot and block these scam extensions before they cause widespread damage. Human reviewers are also stepping in to yank these fakes from the Add-ons store. But as a user, you can’t rely on Mozilla alone—here’s what you can do:

• Verify Before You Install: Always check the official website of your crypto wallet (like MetaMask or Coinbase) to find the legit extension link. Avoid random downloads.
• Watch for Red Flags: If an extension asks for unusual permissions or looks slightly off, don’t install it.
• Keep Software Updated: Ensure your Firefox browser is up to date to benefit from the latest security patches.

For businesses or tech-savvy users, Koi Security suggests treating browser extensions like any other software—use an allowlist and scan them before deployment. This proactive approach can save you from a world of hurt.
