This Week in Tech

KRACKs, Microwaves and leaks

Two HUGE hacks dominate the news this week.

KRACK - patch your WiFi fast!

KRACK affects WiFi at its lowest level - the WPA2 password security that encrypts and protects communication on the network. The bad news is that this security has been cracked, making all communication on the affected network vulnerable. The good news is that most new OS's have patches out there or patches will be coming in the near future. Fixes for routers may take time, but as long as your OS is fixed you should be safe, so make sure you install those updates as soon as they become available! Ars Technica explains how the KRACK exploit works.

SA Database leak - 60 Million affected - and that includes YOU!

This one is a bit more tricky. A database of more than 60 Million South Africans' information has been leaked online - the source of the leak is yet to be determined (read it at My Broadband). The bad news: The leak contains Names, full ID numbers, email addresses, contact details, age, marital status and income estimates. It is a perfect source for identity thieves. The database contains records of almost anyone involved in economic activity between 1990 and 2015. This includes people who have passed away in that time - hence the fact that the leak is larger than our current population!

The good news: There is none. The information is out there and you can't get it back. Watch out for any signs of Identity Theft... You can check if your data is in the leak - go to Have I Been Pwned, enter your email and hold your breath...

What can you do? Not much. Check your credit status now and regularly to see if someone has stolen your identity and obtained credit in your name. Then try to get the credit cancelled / revoked.

Backup and data recovery

The Hacker News has an interesting article on how a ransomware attack took down an American city for four days. Their point is to show the cost of the breach - I think it is a good illustration of the importance of doing backup right...

Microwaves make 40tb hard drive possible

Western Digital has announced that a new microwave technology will enable 40tb hard drives by 2025. Engadget has the details.

LED foils copyright breaking photography

This is an interesting story of how pulsing LED lights can ruin the photos taken by digital cameras and prevent them being used to take copyright breaking images in museums, etc. Digital Trends has the story.

"Hey Siri"

Ever wondered how your smart device (or home speaker, or smart TV) is able to tell when you want to give it a command by using its own special trigger phrase? Apple has published a full explanation of how its "Hey Siri" feature works. As complex as the process is, the astonishing thing is that it takes place all the time without having a noticeable effect on battery life. NB: The same explanation cannot be applied to other devices (all companies use their own technology).

The Uncanny Valley

What is it? This video explains perfectly!

The same people have a well reasoned explanation of why to be sceptical (as I am) of the VR hype...

That's it for this week....
