The nmap command (short for network mapper) is a network exploration/security auditing tool that can rapidly scan networks to help you find out what hosts are available. With nmap, you can discover open ports and services, and even find out what operating systems are on your network. I've used nmap to find out what machines are on a network and what ports/services are open. If I find a port that shouldn't be open, I can close it to avoid security issues.

I started using Linux prior to the advent of sudo. Back then, any time I needed to run admin tasks, I had to first su to the root user, run the task, and then exit the root user. Because root was enabled, some users would simply log in as root and forgo a standard user account altogether. That's a security risk no one should take.

After installing a backdoor to the infected systems, they then downloaded two Java Archive (JAR) files that effectively patched the original vuln.

Immutable Linux distributions ensure that critical system directories are set to read-only mode, which prevents unauthorized changes and enhances overall system security.

There's a lovely device called a PiStorm, an adapter board that glues a Raspberry Pi GPIO [General-Purpose Input/Output] bus to a Motorola 68000 bus. The intended use case is that you plug it into a 68000 device and then run an emulator that reads instructions from hardware (ROM or RAM) and emulates them.

The implant is built as a malicious PAM (Pluggable Authentication Module), enabling attackers to silently bypass system authentication and gain persistent SSH access.

My very first task was switching from LPD (Line Printer Daemon, line printers are kind of high-speed electric typewriters) to #CUPS and so Mandrake was the first distro with CUPS and easy printing.
