The Copilot app cannot be removed arbitrarily. Three cumulative conditions apply: Microsoft 365 Copilot must also be installed on the device, the Copilot app must not have been installed by the user themselves, and the app must not have been launched in the past 28 days.
A Common Vulnerability Exposure (CVE) that cannot reach the privilege plane is operationally ineffective - even at a CVSS Score of 10. This should be a core philosophy that is embedded into the fabric of software engineering.
In order to use agents or in order to use AI in IT operations, all of your systems need to be interconnected and what interconnects all of your systems is an automation platform. Interconnecting systems is only a piece of the puzzle though. There is also some well-founded concern about the autonomous AI systems we are moving towards. AI agents may make decisions and inferences, but enterprises remain hesitant to allow direct execution on production systems.
The most dangerous assumption in quality engineering right now is that you can validate an autonomous testing agent the same way you validated a deterministic application. When your systems can reason, adapt, and make decisions on their own, that linear validation model collapses.
For the longest time, Linux was considered to be geared specifically for developers and computer scientists. Modern distributions are far more general purpose now -- but that doesn't mean there aren't certain distros that are also ideal platforms for developers. What makes a distribution right for developers? Although I consider app compatibility, stability, and flexibility to be essential attributes for most any Linux distribution, developers also need the right tools
I've had several incarnations of the self-hosted home lab for decades. At one point, I had a small server farm of various machines that were either too old to serve as desktops or that people simply no longer wanted. I'd grab those machines, install Linux on them, and use them for various server purposes. Here are two questions you should ask yourself:
Ring the bells, sound the trumpet, the Linux 6.19 kernel has arrived. Linus Torvalds announced that "6.19 is out as expected -- just as the US prepares to come to a complete standstill later today, watching the latest batch of televised commercials." Because while the big news in Linux circles might be a new Linux release, Torvalds recognizes that for many people, the "big news [was] some random sporting event." American football, what can you do?
Bash scripts are a great way to automate all sorts of repetitive tasks -- you can run backups, clear temporary files/logs, rename or batch-rename files, install or update software, and much more. Although writing such scripts isn't nearly as hard as you might think, it does take some time to learn the ins and outs of bash scripting. Also: 6 hidden Android features that are seriously useful (and how they made my life easier) Good news: If you have an Android device, you can enable the Linux terminal, which means you can create or practice your bash scripting on the go.
The vulnerabilities exploit a confused deputy attack. An unauthorized user can manipulate a privileged process to perform actions on their behalf, without having the necessary rights themselves. Specifically, attackers abuse tools such as Sudo or Postfix to modify AppArmor profiles via pseudo-files such as /sys/kernel/security/apparmor/.load and .replace.
I recently wrote about my migration away from VirtualBox to KVM/Virt-Machine for my virtual machine needs. I've found those tools to be far superior (albeit with a bit more of a learning curve) than VirtualBox. Since then, however, I've found another method of working with KVM (the Linux kernel virtual machine technology), one that not only allows me to create and manage virtual machines on my local computer, but also from any machine on my LAN. That tool is Cockpit, which makes managing your Linux machines considerably easier.
Because of that, you need to be very familiar and comfortable with the command line. Or you can install a desktop environment. In my opinion, this is the single easiest way to make Ubuntu Server easier, especially if you're relatively new to Linux. Having a GUI desktop will strip away the fear of having to use the command line, because you'll have plenty of apps to use (such as the file manager, user manager, GUI app store, and much more).
Sudo, for those not familiar with Unix systems, is a command-line utility that allows authorized users to run specific commands as another user, typically the superuser, under tightly controlled policy rules. It is a foundational component of Unix and Linux systems: without tools like sudo, administrators would be forced to rely more heavily on direct root logins or broader privilege escalation mechanisms, increasing both operational risk and attack surface.
"The toolset blends stealth helpers with legacy-era Linux exploitation: Alongside log cleaners (utmp/wtmp/lastlog tampering) and rootkit-class artifacts, the actor keeps a large back-catalog of Linux 2.6.x-era exploits (2009-2010 CVEs)," cybersecurity company Flare said. "These are low value against modern stacks, but remain effective against 'forgotten' infrastructure and long-tail legacy environments." SSHStalker combines IRC botnet mechanics with an automated mass-compromise operation that uses an SSH scanner and other readily available scanners to co-opt susceptible systems into a network and enroll them in IRC channels.
We have already discussed in the previous two articles about file and folder permissions along with special permissions that are supported in linux. The permissions are effective for many scenarios. But what happens when you need more granularity? How do you grant write access to a file to just one specific user who isn't the owner and isn't in the owning group? How do you allow two different groups read access, but only one of them write access?
