Hackers deploy crypto drainers on thousands of WordPress sites

Cryptocurrency is a fantastic innovation, but it also attracts scammers looking to steal your hard-earned digital assets. Be on high alert for sneaky pop-ups that could drain your crypto wallet in an instant. These malicious scripts lurk on seemingly normal websites, often hiding behind a suspicious domain like [invalid URL removed]. Let's dissect how these crypto-draining pop-ups work and how you can protect yourself.

The Cookie Check: Setting the Stage for Crypto Theft

The malicious script operates silently in the background, first checking for a specific cookie on your computer. Imagine a cookie as a small piece of information a website stores on your device to remember things like login details or browsing preferences. In this case, the script is looking for a specific "security cookie" that a legitimate website might use.

Sujee recommends having a good understanding of website cookies and how they work. While they're generally harmless, it's important to be aware that malicious scripts can exploit them. If the script doesn't find the expected cookie on your device after connecting to the suspicious domain dynamic-linx[.]com, that's its cue to spring the trap. The malicious script initiates its functionality by conducting a targeted search for a specific cookie on the user's device. This cookie, identified by the name "haw," likely serves as a marker for the script's intended behavior. In the absence of this cookie, the script triggers a secondary action, injecting malicious code directly into the webpage. The details of this injected code are provided below.

Deceptive Pop-Up: A Luring Invitation to Disaster

Once the script detects the missing cookie, it injects harmful code into the webpage. This code then displays a fake promotional pop-up, often designed to look legitimate and trustworthy. These pop-ups might entice you with free NFTs (non-fungible tokens, a type of digital asset) or exciting website discounts. The visuals and wording can be very convincing, making it easy to fall for the deception.

The Wallet Connection Trick: Stealing Your Crypto in Plain Sight

Clicking the pop-up's "connect" button triggers the theft. It mimics popular wallets (MetaMask, Coinbase) to trick you into thinking it's legitimate. But beware! These scripts can also exploit "WalletConnect" to steal from various wallets, not just the ones displayed.

The Key to Staying Safe: Vigilance and Smart Practices

Sujee strongly recommends taking proactive steps to safeguard your crypto assets. Here are some crucial practices to remember:

  • Trusted Sites Only: Connect your wallet only to well-known, reputable websites. Double-check URLs for typos, especially those leading to suspicious domains like dynamic-linx[.]com.
  • Pop-Up Skepticism: Treat unexpected pop-ups with suspicion. Do they offer unrealistic benefits or create pressure? It's likely a scam.
  • Think Before Clicking: Don't rush to connect your wallet on pop-ups. Analyze the situation and verify the website URL. When unsure, avoid connecting.

Extra Security Tips (Optional):

  • Software Protections: Consider installing a reputable ad blocker and anti-malware software to prevent malicious scripts from loading.
  • Hardware Wallets: For an extra layer of security, explore hardware wallets for your crypto assets.

By following these steps and staying alert, you can shield yourself from these deceptive pop-up scams and safeguard your cryptocurrency. Remember, online security is an ongoing battle. Stay informed about threats and update your security software regularly. With a little caution, you can navigate the exciting world of crypto with confidence.
