Raspberry Pi is a little useful computer for learning programming and building projects. It comes with Debian Linux based modified operating system called Raspbian. It is the most widely installed OS on RPi. In a recent update, the Raspberry Pi OS installed a Microsoft apt repository on all machines running Raspberry Pi OS without the person’s or admin’s knowledge. Every time a Raspbian device is updated by having this repo, it will ping a Microsoft server. Microsoft telemetry has a bad reputation in the Linux community. Let us see why and how this matters to Linux users.

As you know, Red Hat recently announced that CentOS Linux 8, as a rebuild of RHEL 8, will end in 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux. The news met with a strong reaction from the open-source community and CentOS users. Today, Red Hat released a new option where RHEL developer subscriptions can now be used in production environments. The developers and team can have up to 16 systems. In other words, it is a no-cost RHEL that small groups and developers can use to build packages and in production environments.

The last ten years in the computer and IT security world are crippled with so many vulnerabilities. We saw massive cloud computing adoption and end-users using mobile devices with high speed 4G LTE networks. A threat actor may have exploited such weakness in modern computers and networks. Let us look into top vulnerabilities and the attack surface in this decade (2010-2020) that affected Linux/Unix, macOS, IT, cloud-computing, and computers in general.
