Security news weekly round-up - 14th May 2021

Time waits for no one. It feels like yesterday since the last edition of this round-up only for me to check, and it's 2 weeks already, and I am like: Are you kidding me?

What more could I say? Let's move on.

Hopefully, I can keep track of time and I will be here next week to say: "Yeah I made it this week".


This week it's everything security.

Using Bluetooth Low Energy, the data is being sent to nearby Apple devices that do connect to the Internet, and then sent to Apple’s servers, from where it can be retrieved at a later date.

Big Cybersecurity Tips For Remote Workers Who Use Their Own Tech
