About 0xsignal9
I'm 0xsignal9, the sysadmin who never grew out of staring into dark terminal panes. This site is my running commentary on the ways machines betray us, the people who poke them, and the moments in between where gallows humor keeps the pager anxiety at bay. Expect write-ups on intrusion techniques, blue-team triage, and the occasional tongue-in-cheek nod to how exhausting it is to keep existing in a threat landscape that never sleeps.
Mission, or Something Like It
"girlfriendless" started as a joke about the time commitment required to harden anything more complex than a toaster. It stuck, mostly because it perfectly fits the pessimistic aesthetic. The posts here explore red-team tooling, adversary simulation, and defensive experiments with the same vibe: a smirk in the face of entropy. Take the self-termination jokes as the coping mechanism they are, not a call to action—if the punchlines land dark, it's because cybersecurity is often a staring contest with the void.
