Software Update Alters Android App into Malware, infecting Millions of Devices

An app running on android phone that was availed on Google Play turned to a malware that hijacked over 10 million devices. The app dubbed as Lavabird Ltd’s Barcode Scanner offered QR code reader and a barcode generator and had been installed on over 10 million mobile phones.

The app had been used for over years without any problem, until recently after it was updated. Multiple reports indicate that users started complaining about sudden adverts that started popping up on the screens of their devices.

In report published by Malwarebyte, the duration of the malware was not accurately predicted. However, preliminary analysis revealed that the software update that was creating discomfort to the users might have come into effect on December 4, 2020. Normally, ads are displayed on apps that are free of charge while premium apps do not display ads.

The issue was reported to Google by Malwarebytes, and the app has been pulled down from the Google Play. However, those who had already downloaded the app will still have it running on their devices. Users will have to uninstall the malicious app manually from their phones.

Malwarebytes, as quoted by ZDNet, noted that: “User get a free app, while the app developers and the ad SDK developers get paid. But every once in a while, an ad SDK company can change something on their end and ads can start getting a bit aggressive.”

How Human Noise Kills Marine Species, as revealed by Scientists

Scientists have warned that the discord of noise made by humans is harming marine species . A comprehensive assessment revealed that large noise from human activities was as harmful as pollution, overfishing and climate change . The study that was conducted by the Journal Science exposed how marine animals can hear from far distances than they can see or smell. According to a report published in the Guardian, most of the marine life uses sound to catch prey as well as attracting a mating partner. Prof Carlos Duarte of King Abdullah University in Saudi Arabia argued that: “Marine animal can only sea up to around 10 meters, smell up to around a hundred meters, but they can hear across the entire ocean basins.” The research concluded that sound “is very important in the marine ecosystems, and noise is pervasive, affecting animals at all levels .” The increasing cacophony in the marine habitat is interfering with how marine animals respond to various survival...

Carbon dioxide to Make Jet Fuel, Study Reveals

Photo Source: twitter.com Aircrafts release a lot of carbon dioxide in the atmosphere which contributes to climate change. A research that was conducted by Science News and reported on December, 22 2020 stated that there was a new iron-based catalyst that has been invented to convert carbon dioxide into jet fuel. It is only a matter of time that carbon dioxide pumped to the atmosphere by planes could be sucked and used to power the same. The air travel’s footprint in carbon emissions could be tremendously curtailed, if the carbon dioxide that is released is recycled to generate fuel. As per Science News reports, Air transport contributes to about 12 percent of the entire transportation carbon-related emissions. Unlike cars, aircrafts cannot carry bigger batteries which can be run on electricity generated from wind or solar panels. The current breakthrough in the conversion of carbon dioxide to fuel involves cheap ingredients such as iron and transformed through a single s...

Why World Tycoons Should Emulate Microsoft founder, Bill Gates, in the Battle against Climate Change

As a key defender of the environment, he is quoted by the Guardian saying that: “The idea of adding new electricity capacity- you can’t just go build coal plants.” The Guardian reported that Gates likes using private jets because he can get affordable fuel for flight. He revealed that he has already footed the bill of carbon footprint to a group dubbed Climeworks , a firm that captures up direct air in Iceland. Gates pointed out that the future of vehicles travels lie with electric cars; but excluded the el...
