In just 24 hours, 5,000 Android devices are conscripted into mining botnet

The previously unseen malware driving the botnet has worm-like capabilities that allow it to spread with little or no user interaction required, researchers with Chinese security firm Netlab wrote in a blog post published Sunday. Once infected, Android phones and TV boxes scan networks for other devices that have Internet port 5555 open. Port 5555 is normally closed, but a developer tool known as the Android Debug Bridge opens the port to perform a series of diagnostic tests. Netlab’s laboratory was scanned by infected devices from 2,750 unique IPs in the first 24 hours the botnet became active, a figure that led researchers to conclude that the malware is extremely fast moving. – Dan Goodin, Ars Technica http://ift.tt/2E4H641

Now even YouTube serves ads with CPU-draining cryptocurrency miners

The ads contain JavaScript that mines the digital coin known as Monero. In nine out of 10 cases, the ads will use publicly available JavaScript provided by Coinhive, a cryptocurrency-mining service that’s controversial because it allows subscribers to profit by surreptitiously using other people’s computers. The remaining 10 percent of the time, the YouTube ads use private mining JavaScript that saves the attackers the 30 percent cut Coinhive takes. Both scripts are programmed to consume 80 percent of a visitor’s CPU, leaving just barely enough resources for it to function. – Dan Goodin, Ars Technica http://ift.tt/2FjaALw
