In the previous research conducted by security IT-companies, it was found that a miner could be run as long as the web browser was running. Should you close the browser and mining activity stops as well. However, as per the latest technique spotted by Malwarebytes, some suspicious website owners can mine crypto coins like Monero even after browser software is closed.

How it works and is it possible to prevent it?

It was found that when a user visits a website, there is a light growth in the CPU activity. As the activity is not maxed, the user doesn’t notice anything strange. Once the user closes the browser application, the CPU activity is still remains higher than normal and cryptomining process continues. So what’s the trap? How are webcriminals capable to do this?

Actually, even when you close the browser, there’s one hidden pop-under window that still remains open. It’s sized to fit under the taskbar and hides behind the clock. The coordinates of this window might be different, but it all in all follows x -100 and y -40 position principle.

Persisting hidden cryptomining

You can broaden the taskbar to spot the window, enabling transparency might also help you.

To spot that sort of activity, you can run Task Manager and ensure that there are no browser processes hiddenly running. You can also look for the highlighted browser icon in the taskbar field.

'Kodak Miner' Turned Out to be a Scam

KashMiner by Spotlite USA was promoted as Kodak branded bitcoin miner

The KashMiner bitcoin miner, exhibited at the Kodak stand during the CES technology show in Las Vegas, was in fact a product designed to mislead potential consumers and with a potentially unattainable potential return. This is reported by BBC.

Spotlite USA is licensed by Kodak's lighting division, which allows it to use the famous brand in its products. In January 2018 the company introduced its miner and announced that it intends to lease it. According to its business plan, potential users had to pay a commission before getting the device. It was expected that after depositing $ 3,400, the customer will receive a device that will allow him to easily cover expenses and receive revenue from bitcoin mining.

However the company did not have an official Kodak license to use the brand in the production of mining equipment and initially overstated the indicators of the potential profit of its device, refusing to take into account the growing complexity and costs of bitcoin mining. The advertising materials reported that KashMiner brings $ 375 a month, which, subject to a 2-year contract, would allow the client to receive $ 5,600 of profit after paying a commission. Experts from the industry of cryptocurrency call this offer a scam.

There is no way your magical Kodak miner will make the same $375 every month.

CEO Spotlite USA Halston Mikail previously reported that he plans to install hundreds of miners at the headquarters of Kodak. According to him, he already managed to place 80 miners there, but the Kodak spokesman denied this information.

While you saw units at CES from our licensee Spotlite, the KashMiner is not a Kodak brand licensed product. Units were not installed at our headquarters.

In a phone call with the BBC, Spotlite's Halston Mikail said the US Securities and Exchange Commission (SEC) had prevented the scheme from going ahead.
