This Android malware is so dangerous, even Google is worried


Google has confirmed reports of the existence of an extremely potent Android malware (opens in new tab), and notified victims that they’re being targeted.

In a blog post (opens in new tab), Benoit Sevens, and Clement Lecigne of the company’s Threat Analysis Group said cybersecurity researchers from Lookout were right when they discovered, and warned users, of the existence of a dangerous Android virus (opens in new tab) called Hermit.

What is Hertzbleed?

Hertzbleed is a new attack that takes advantage of a power-saving feature common to modern computer chips in order to steal sensitive data. It has been demonstrated in the lab and could be used by hackers in the wild.

Most chips use a technique called dynamic frequency scaling, or CPU throttling, to increase or reduce the speed with which they carry out instructions. Ramping the power of the CPU up and down to match demand makes them more efficient.

In the past, hackers have shown that they can read these power signatures and learn things about the data being processed. This can give them a foothold to break into a machine.

The team behind Hertzbleed found that you can actually do something similar remotely by watching carefully to see how quickly a computer completes certain operations, then using that information to determine how it’s currently throttling the CPU. Demonstrating that such attacks can be performed remotely makes the issue much more dangerous, because remote attacks are much easier for hackers to carry out.

What does it mean for you?

Intel declined a request for interview by New Scientist, but admits in a security alert that all of its chips are vulnerable to the attack. The company said that, through such an attack, it “may be possible to infer parts of the information through…

Worried about your cellphone being hacked. You’re not alone


Hackers and hacking have been around for a long time.

Cybernews, an online research-based publication that investigates and tracks hacking, said the term “was first used in relation to using technical know-how back in 1955 at a meeting of the Technical Model Railroad Club. In the meeting minutes, it was used to describe how members modified the functions of their high-tech train sets.”

More than 60 years later, there are lot more items around capable of being hacked than just high-tech train sets. So the folks at Bespoke Software Development (www.bespokesoftwaredevelopment.com) commissioned a study to find out what household items could be targets for hackers.

Using an online analytics tool, the company’s study found the No. 1 item, by far and away, was the cellphone. Worldwide, the study found that the phrase “How to know if your phone is hacked” or similar phrases were used 716,400 times during the study period, which took place earlier this month.
