In a similar development, a security researcher named Arnau has published a proof-of-concept project that showcases how troublesome actors can exploit such public Wi-Fi networks and print free money.
As expected, the miner being used in the concept is from CoinHive. It’s a Monero miner that uses the CPU power to calculate hashes with Cryptonight PoW hash algorithm for mining.
The real-world demo of the attack using Kali Linux is shown below. The researcher has shared this attack for academic purposes and to showcase how easily one cybercriminal can exploit your weak security practices.
