The security service of AvtoVAZ, the corporate newspaper of the Volzhsky Avtostroitel car factory writes, has encountered intellectual crime. A mysterious intruder, two years mine mine cryptocurrency, hiding and powering the farm in the electrical cabinets of the 19th hall of the control conveyors. Mineil employee is quite successful.

Link to the news .

“Security experts have found that the intruder used a communication channel to the Internet using a USB 4G modem for the operation of the crypto farm, thereby gaining remote access to his equipment.

I also managed to get to the electronic cryptographic wallet. In the transaction logs, transactions from August 2016 to May 2018 were recorded for a total equivalent of more than 1.2 million rubles.

In the comments below I tried to calculate the composition of the farm:
Those. There were several devices on the farm that consumed every 1000 kW, and how many devices - 600,000 rubles / 12 = 50,000 rubles / 6 rubles per 1 kW = 8333 kW. Those. approximately 8-9 nodes in the farm were, as an option.
