Which Android smartphone is safer?

The increasing vulnerabilities discovered in Android are making the security one of the priorities when we go to buy a smartphone. A team of researchers of the Cambridge University has created a database of vulnerabilities which allows them to create a list of the safer Android devices. We'll talk about it, as well as other selected news of the day: a cyberattack to the South Korean subway, the upgrade of the most famous manual of cyberwar and a weapon to “kill” drones.

 Unsafe Android devices over time
87% of Android devices are unsafe according to AndroidVulnerabilities.org, a situation which has been getting worse in a geometric proportion since 2011. The statistics generated by the project, through installed apps in volunteers devices, allow to make a ranking of more and less safe smartphones, being Nexus the most secure, followed by LG, Motorola and Samsung. The less secure are Walton (the worst), Symphony and Alps.


The subway of South Korea, attacked

Unfortunately, today the insecurity doesn’t lie only in our smartphones and computers. The Internet of Things and the growing computerization of the critical infrastructures mean that we are more exposed. A good example is the attack, revealed by a judge, suffered by the system of the South Korean subway on spring 2014: 60 computers were infected with malware, supposedly by North Korea. The news come to light today, at the same time as the supposed technical problems which left almost KO, on Sunday, the North American airline Southwest Airlines, which had to delay 500 flights.

The Manual of Tallinn has been upgraded

According to the experts, the problems with the airlines come more and more from their increasing computerizing than from external attacks. Anyway, don’t forget that the communications systems are clear targets of cyber war. Just this week, cyber war experts are gathered in the Estonian capital to upgrade the Tallin Manual About International Law Applicable to Cyber War, the most serious effort we know to put some order in this field.

DroneDefender

Talking about militia, we finish with a weapon which could be used in the most likely scenarios to be attacked by drones: the Battelle DroneDefender, a kind of rifle which shoots no bullets but radio impulses which neutralize flying drones and force them to land. Until now, anyone who wanted to defeat a drone would do it shooting with a gun. With DroneDefender we avoid destroying the little plane and, if our neighbor was the owner, we won’t have to pay it.

The science, as the zarzuela said, is growing by leaps and bounds. We hope to our readers a great Wednesday. See you tomorrow.
