Chinese Miners to Fall Victims of Ransomware

In China, a ransomware spreads, victims of which are Bitcoin miners. The damage from its activities is measured in tens of thousands of dollars. This is reported by Trustnodes.

The virus infects miners, released by Bitmain, and requires you to send 10 bitcoins, otherwise threatening to cause overheating of the device.

The problem is solved by formatting the SD card of the infected device, however, as Trustnodes notes, the whole process can take up to four days, while malicious software rapidly spreads to the other miners.

Probably, the virus comes with an "improved" firmware for miners. Some owners install such firmware to “overclock” their ASIC devices and improve their performance.

The first messages about the virus refer to August last year. In particular, Antminer S9, T9 and even L3 + for Litecoin were attacked. Over time, the malware has been improved. Now its distributor himself can decide when to display a message requesting a ransom. One miner also said that one night the address to which the 4,000 devices belonging to him sent the mined cryptocurrency was changed to the address of the hacker, which brought him $ 8,000.
