The Police Can Probably Break Into Your Phone

The companies frequently turn over data to the police that customers store on the companies’ servers. But all iPhones and many newer Android phones now come encrypted — a layer of security that generally requires a customer’s passcode to defeat. Apple and Google have refused to create a way in for law enforcement, arguing that criminals and authoritarian governments would exploit such a “back door.”

The dispute flared up after the mass shootings in San Bernardino, Calif., in 2015 and in Pensacola, Fla., last year. The F.B.I. couldn’t get into the killers’ iPhones, and Apple refused to help. But both spats quickly sputtered after the bureau broke into the phones.

Phone-hacking tools “have served as a kind of a safety valve for the encryption debate,” said Riana Pfefferkorn, a Stanford University researcher who studies encryption policy.

Yet the police have continued to demand an easier way in. “Instead of saying,

Computer Scientists Break the ‘Traveling Salesperson’ Record

When Nathan Klein started graduate school two years ago, his advisers proposed a modest plan: to work together on one of the most famous, long-standing problems in theoretical computer science.

Original story reprinted with permission from Quanta Magazine, an editorially independent publication of the Simons Foundation whose mission is to enhance public understanding of science by covering research develop­ments and trends in mathe­matics and the physical and life sciences.

Even if they didn’t manage to solve it, they figured, Klein would learn a lot in the process. He went along with the idea. “I didn’t know to be intimidated,” he said. “I was just a first-year grad student—I don’t know what’s going on.”

Now, in a paper posted online in July, Klein and his advisers at the University of Washington, Anna Karlin and Shayan Oveis Gharan, have finally achieved a goal computer scientists have pursued for nearly half a

What is an Air-gapped computer? Can you break into one?

An Air-gapped computer is usually a computer that is completely isolated and disconnected from the Internet and other computers. It does not form part of any other network that may or may not be connected to a WAN or Internet for security purposes. This post talks about the air-gapped computer and its use. We’ll also check out the probability of an air-gapped computer getting hacked.

What is an Air-gapped computer?

An air-gapped computer is a computer that is used to safeguard critical data and protect it from hackers and malware. It is a computer system that is not connected to any other computer. It is never online as it has no Internet connection to remove the possibility of it ever getting hacked or infected.

In air-gapped computers, the objective is to keep custom apps (programs) and data safe. Since there is a possibility of malware propagating through Flash drives, they
