While the domain itself does not host any obvious phishing pages or ransomware downloads, it has become known for delivering a stealthy JavaScript‑based cryptocurrency miner that runs in visitors’ browsers. In this post we’ll unpack:

Pull the Ethernet cable or disable Wi-Fi. This stops the miner from communicating with pwnhack.com and prevents further damage. pwnhack.com miner

It may also pause mining when Task Manager, Resource Monitor, or Activity Monitor is opened. Pull the Ethernet cable or disable Wi-Fi
