Browsers hijacked to mine crypto for hackers

The new “malvertising” to harness the computing power of unsuspecting visitors to certain websites for the purpose of mining cryptocurrencies
18 September 2017   1122

Cryptocurrency world has suffered a lot from the hackers.
Now, an unknown hacker or group of hackers has targeted some video streaming and gaming sites with “malvertising,” which uses online ads as channels to transmit script that causes visitors’ browsers to mine altcoins for the perpetrator, as reported by an ESET malware researcher Matthieu Faou. 

Malvertising - the practice of delivering malicious code to a website via an online ad network without the victim actually downloading anything to the affected device. According to ethnews.com, advertising network operators are unaware of the malicious content being sent to websites on the network. The content contains code that can adversely impact the browsing experiences of these sites’ users and potentially even put their privacy at risk.

While cryptocurrencies like Bitcoin now require specialized hardware to mine them effectively, Feathercoin and Litecoin, two of the cryptocurrencies sought by the perpetrator(s) of this attack, are designed to be minable via regular CPUs.

According to Faou’s post, all the Feathercoin malvertising scripts analyzed by the ESET team contained a single wallet address, suggesting a single perpetrator or group of perpetrators. The other crypto mined, Monero, is among the most anonymous of cryptocurrencies, and thus the team could not ascertain whether all the Monero mined through these attacks was sent to a single wallet. 

'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.
