South Korean police have detained five people for installing software for hidden mining cryptocurrency on more than six thousand computers. It is reported by CCN , citing local media.

According to the police, a group of hackers sent out more than 30,000 emails containing malware.

From October to December 2017, the attackers sent letters to people who at the time were looking for work. Having collected a database of email addresses on forums and job search platforms, hackers posed as human resource managers and potential employers.

A file was attached to the text, which, upon opening, automatically downloaded malware onto the computer. A total of about 6,000 users were affected. However, the hackers were able to earn a fairly modest amount of $ 1000.

“Thanks to antivirus software developers and security companies, a group of hackers failed to make a significant profit. In most cases, antiviruses detected malware within 3-7 days. When malware was detected, the hackers sent new ones, but in this case the antiviruses coped, ”the police said.

According to McAfee Labs , it is the fourth quarter of 2017 that accounts for the birth of a wave of popularity of hidden mining (cropping-tejking). In the second quarter of 2018, the number of such attacks increased by 86%. Also, experts noted that today hackers are interested not only in computers, but also in the computing power of mobile gadgets that are connected to the Internet.

In September, the sites for the municipal authorities of the Indian province of Andhra Pradesh were infected with hidden mining scripts.

In addition, the results of a recent study by Avast showed that in December 2017, when the price of Bitcoin reached its historic maximum, 34 million hidden mining attacks were made on users from Russia.
