WiFi’s tougher WPA3 security is ready

WiFi security is finally getting an upgrade after 14 years. The Wi-Fi Alliance has officially launched WPA3, the next-generation standard that promises to tackle many of the vulnerabilities that have persisted in wireless networking. Most notably, it brings individualized data encryption that should protect your data against eavesdropping from within the WiFi network. You’ll also get tougher password-based sign-ins through Simultaneous Authentication of Equals, a key establishment protocol that reduces the chances of someone guessing your password — even if it’s lousy.

Scientists create ultra-thin membrane that turns eyes into lasers

It will still be a while before scientists are able to harness Superman-like laser vision, but the technology is now closer than ever before thanks to a new development from the University of St Andrews. The team there have created an ultra-thin membrane laser using organic semiconductors, which is for the first time compatible with the requirements for safe operation in the human eye. Even though the membrane is super thin and flexible, it’s durable, and will retain its optical properties even after several months spent attached to another object, such as a bank note or, more excitingly, a contact lens.

Global cyberattack targets 200,000 network switches

The past few days haven’t been great for the internet’s broader security. Iran’s Communication and Information Technology Ministry has reportedthat it was a victim in a global cyberattack that compromised about 200,000 Cisco switches that hadn’t yet received patches for exploits in the company’s legacy Smart Install protocol. The attackers displayed a US flag on at least some screens, complete with a “don’t mess with our elections” warning, but the attack wasn’t focused on Iran — only 3,500 switches fell to the exploit in the country. About 55,000 of the victim devices were in the US, IT Minister Mohammad Javad Azari Jahromi said, while 14,000 were in China. Other victims were located in Europe and India.

Scare Away Intruders With This Home Security Concept That’s Literally Just a Shadow

Taking a page from Kevin McCallister’s playbook in Home Alone, a landlord in Tokyo has developed a novel way for residents who live alone to feel safer. A tiny projector makes it appear as if there’s another person in the apartment from the outside by faking a moving, shadowed silhouette on a window curtain.

Facebook gave researcher anonymized data on 57 billion friendships

The Guardian reports today that Cambridge University researcher Aleksandr Kogan’s relationship with Facebook wasn’t limited to his now infamous “thisisyourdigitallife” app. He had actually also received an additional sizable chunk of data from Facebook that he used for a research paper published in 2015. This dataset, however, differs quite a bit from that collected through Kogan’s personality app. While large in volume, this other set was anonymized and aggregated with no personally identifiable information included. As the 2015 research paper states, the data included “every friendship made on Facebook in 2011 in every country in the world at the national aggregate level,” which summed up to over 57 billion friendships.

Apple will store China’s iCloud keys on local servers

Apple has already bent over backwards in a bid to keep doing business in China, but it’ll have to bend a little further. As of the end of February, the company will host mainland Chinese users’ iCloud keys on servers located within the country — and they’ll be jointly run by a state-backed company, Guizhou Cloud Big Data Industry. The company has no choice if it wants to keep offering iCloud to Chinese users, as the law now requires that any cloud services have domestic ownership and store their data within China’s borders.
