Bad guys can access all of the compute power connected to a particular public Wi-Fi network, all at once, to mine for cryptocurrency.

Surreptitious crypto-mining using unsuspecting victims’ computers has become a rapidly proliferating phenomenon – and now it has collided with coffee shop Wi-Fi hijacking.

A software developer known as Arnau Code has developed a proof-of-concept for a man-in-the-middle (MiTM) attack, for use in coffee shops and other places where legions of students and teleworkers take advantage of free Wi-Fi. It shows how the bad guys can gain access not just to one victim’s CPU resources to mine for virtual currency but to all of the compute power connected to that particular Wi-Fi network, all at once.

Some weeks ago I read about this Starbucks case where hackers hijacked laptops on the WiFi network to use the devices computing power to mine cryptocurrency, and I thought it might be interesting perform the attack in a different way,” the developer explained in a blog, with the disclaimer that his research is “strictly for academic purposes.”

Appropriately named CoffeeMiner, the script allows for an autonomous attack on the Wi-Fi network to do just that. It’s the result of a multistep – but not challenging, according to Code – process.
