Linux G. Fossman

@triskelion @purism I appreciate what GrapheneOS and other projects are doing. I wish gOS good luck in:
- getting early access to future #AOSP sources as development is no longer public.
- fixing the myriad of #Google shenanigans with the OS and Chromium.
- getting mental health help for the main developer - he deserves all the help he can get.

Unlike gOS, #Linuxphone development is not riding on decades of Google funded development of the OS. Progress is therefore slower but it is improving gradually.

Besides #PureOS, there is also #Mobian and #postmarketOS - I especially look forward to the latter's future #ImmutableOS version which would have security benefits as well.

On Linux systems, some of the most dangerous hacking tools are already preinstalled. Bash, curl, netcat, awk, even less — these common binaries can be chained together for stealthy attacks. They are called Linux LOLBins, short for Living Off the Land Binaries. Rather than dropping new malware, an attacker can leverage what is already there to stay undetected. Need to exfiltrate data? Use curl or scp. Want a reverse shell? Try bash or socat. Fileless persistence, privilege escalation, lateral movement — it can all happen through trusted tools.

Security is not just about locking the doors. It is about knowing which ones are left wide open by default.

In 2003, an attacker breached a public-facing server and attempted to slip a subtle backdoor into the Linux kernel’s source code. The exploit was deviously simple, a small modification that would grant root access under specific conditions, making it nearly invisible to casual review. However, the Linux development process requires cryptographic signatures and meticulous code auditing. When a routine integrity check flagged an unexpected change, developers quickly investigated and discovered the malicious code before it could ever make it into an official release. This incident became a defining moment in Linux security, proving that while open source code is accessible, its real strength lies in the transparency and scrutiny of its community.
