Smartphone Slows Alert Cryptocurrency Activities

Have you ever felt a smartphone suddenly slowing down, heat, and the battery quickly drained without obvious reason? If so, it's possible that your cellphone has been hijacked to mine cryptocurrency.

Reporting from the page Phys.Org, Thursday (08/23/2018) the new cyber attack is called the term cryptojacking by security experts.

"This activity consists of trapping internet servers, personal computers or smartphones to install malware to mine cryptocurrency," said Gerome Billois, an expert at the Wavestone IT service management company.

Mining is basically a process of helping to verify and process transactions in certain virtual currencies. Mining operations connect thousands of processors together to increase the computing power available to get cryptocurrency.

Mining, including bitcoin, ethereum, monero, and other cryptocurrency may be very profitable, but requires large investments and generates large electricity bills. But hackers have found a cheaper option, which is to secretly exploit the processor on a smartphone.

To lure victims, hackers turn to the digital world equivalent to the secret trout of Trojan horses from Greek mythology. Complete, inside applications or programs that seem harmless hide the evil.

"Recently, we have found that a version of the popular game Bug Smasher, which was installed from Google Play between one and five million times, has been quietly mining monero cryptocurrency on a user's device," said a researcher at IT security firm ESET.

Not only that, David Emm, a security researcher at Kaspersky Lab revealed that this phenomenon seems to be growing. The reason is, more and more mobile applications that hide Trojan horses associated with cryptocurrency mining programs have appeared on the platform in the last 12 months.

Cryptojacking affects most smart phones running Google's Android operating system. Apple has more control over applications that can be installed on their phones, so hackers have not targeted the iPhone.

But the good news is that Google has recently been trying to clean up the Play Store from Cryptocurrency activities.
