Bitcoin Botnet Aims to Makes Money From Wise Devices

Hackers may be hijacking internet-connected fridges, toasters and light bulbs te order to use their computing power to mine bitcoins, researchers have exposed.
IBM researchers discovered a bitcoin mining component te a fresh variant of Mirai—a form of malware that exploits security vulnerabilities to take control of devices connected to the so-called Internet of Things (IoT).
Security stiff McAfee recently estimated that more than Two.Five million IoT devices were infected by the Mirai botnet ter 2016, however it is not clear how many compromised devices may have bot used to mine the virtual currency.
“We do not have any insight into whether or not bitcoins were actually mined during thesis attacks,” Dave McMillen, a senior threat researcher at IBM, tells Newsweek. “It is also not known whether or not this is the deeds of one group or many… This Mirai variant could be appealing to others te the future due to the potentially large volume of devices that could be involved.”

Security experts have previously warned that hackers could target brainy devices ter order to mine bitcoin. Mikko Hypponen, chief research officer at F-Secure prophesied te 2014 that cryptocurrencies suggested a fresh method for criminals to profit from vulnerable devices.
“Attacks don’t target the user but the laptop itself,” Hypponen said. “Internet of Things devices can be hacked to mine cryptocurrencies and make money.”
Mining bitcoin—the process of confirming bitcoin transactions and adding their record to bitcoin’s public ledger te order to generate fresh units of the currency—requires vast amounts of computing power. It would therefore require a giant network of IoT devices te order to have a successful mining operation.
Details of the Mirai variant were published by the IBM researchers ter an online blog, te which they speculated hackers would be incentivized to mine for bitcoin te order to facilitate cybercriminal activities.

According to a 2016 examine by the security rock-hard BullGuard, up to 185 million devices may be at risk of being compromised by Mirai. Hackers used the network of compromised devices te a series of attacks that caused several major websites to go offline, including Netflix, Reddit and Twitter.
Projections from technology research hard Gartner suggest the punt may escalate if security fixes are not implemented by device manufacturers. According to Gartner, there will be more than 20 billion IoT devices by 2020, while estimates from ABI Research waterput the figure closer to 30 billion. Cybersecurity experts warn that too many manufacturers treat security spil an afterthought when producing internet-enabled devices.
Chris Boyd, an analyst at the security hard Malwarebytes, told Newsweek te an vraaggesprek last year: “The problem here is that many IoT devices are horribly cracked security-wise because it costs money to ensure a reasonable standard of protection on a product.”
This lax treatment will inevitably lead to much more devastating attacks, according to cybersecurity veteran John McAfee.
“The attacks are leisurely escalating, similar to the way America developed the atomic bomb,” McAfee, who created the eponymous antivirus rekentuig software but is now longer connected to it, said ter October. “Clearly there are weaknesses. Anticipate that thesis will be exploited te a big way.”
