Case Inference #4 — The Admin Who Blinked Twice

“If you squint hard enough, a Gmail handle becomes a breadcrumb.”
— InferenceLog, Vol. 4

Situation:

At Cypress Warden Technologies — a place where documentation goes to die — we were tasked with preparing a vulnerability assessment. The only problem? Their head network admin, let’s call him Connor, treated us like we were auditioning for CSI: Sysadmin Unit.

Three hours of polite teeth-pulling yielded only:

• A personal email: [email protected]
• A passing mention of an old Linux box “that still boots… usually.”

Classic.

Step One: The Handle

So, cmatrix404. Not the worst handle we’ve seen (that honor goes to rootkit69xX), but definitely promising.

We did what any normal human does in 2025 — Googled it.

Turns out Connor’s alter ego has:

• Posted on forums about RHEL kernel panics.
• Uploaded a gist with init.d scripts dating back to Obama-era syslog.
• Starred a repo named rhel5-survival-kit.

The evidence trail was about as subtle as a bootloader error.

Step Two: The Email

Plugged it into:

• HaveIBeenPwned – Compromised in three breaches, one dating back to Myspace. (Respect.)
• EmailRep.io – “Moderate Risk.” Which is also how we’d describe the company’s firewall rules.
• Found a comment thread where he complained about the RHEL package manager. In 2018.

This confirmed two things:

1. The RHEL server exists.
2. Connor’s been too emotionally attached to it to decommission it.

Analyst Memo (Redacted for HR Friendliness):

To: Jawad Safari, IT Manager
Subject: Friendly Ghosts in the Server Room

While conducting passive reconnaissance (no intrusion, just open-source elbow grease), we identified what appears to be a RHEL 5.8 server in use.

Just a reminder: Red Hat stopped issuing security updates for 5.8 back when Game of Thrones was good.

We recommend:

• An immediate OS inventory check (maybe ask nicely this time).
• Isolating or upgrading legacy systems to prevent “archaeological” breaches.
• Instituting quarterly patch reviews, before the ghosts in the server room get bolder.

We’re not saying your network is vulnerable.
We’re saying your network wears bell bottoms and thinks TikTok is a mint.

Takeaway

Connor didn’t say much, but his email did. Inference isn’t always about finding the smoking gun — sometimes it’s about reading the room, checking the GitHub stars, and realizing someone’s still ssh-ing into a machine that last saw sunlight in 2013.

You don’t need admin credentials to smell rot.
Just curiosity, restraint, and an appreciation for tragic sysadmin nostalgia.

Want to Try?

Pick a handle like cmatrix404, run it through:

• Google
• GitHub
• HaveIBeenPwned
• Reddit

Then ask yourself: Would I trust this person with a production box?
