Crypto exchange Gate.io has removed web analytics tool StatCounter from their website following a breach report by cybersecurity firm ESET, according to an official blog post published today, Nov. 7.
The company has reported that they immediately removed StatCounter’s traffic stats service after receiving a security notice by ESET about suspicious behavior. Gate.io claimed they subsequently scanned the website with 56 antivirus products, and “no one reported any suspicious behavior at that time.” However, the firm still changed its traffic tracker, also reporting that “users’ funds are safe.”
The hackers managed to add a piece of malicious code containing “myaccount/withdraw/BTC,” which intends to replace the destination address of a Bitcoin transfers by crypto exchange users with an address belonging to the attackers.

As reported by Cointelegraph earlier this year, JS has been one of the major tools of hackers implemented in cryptojacking. According to the analysis, JS-based browser add-ons and extensions are “extremely vulnerable to hacking attacks” and often used for hidden mining by deploying users computing resources. For example, in mid-October, researchers found a crypto-mining malware that hides itself behind a fake Adobe Flash update.
