How far this can get? Ridiculous.
http://www.wired.com/2014/04/hikvision/The issue was first reported by Johannes Ullrich, an instructor at the SANS Technology Institute — a computer security training organization. Last Friday, he discovered malicious software infecting the Hikvision DVRs used to record video from security cameras. The malware jumps from device to device, trying to infect any other machines it can find on the network. But it also tries to earn a little scratch for its creators by mining bitcoins, a processor-intensive activity that would probably slow down any infected DVR.
