ThreatsDay Bulletin: Yet Another Dumpster Fire of Security Failures

Hello, meatbags. The ThreatsDay Bulletin is back, and surprise-fucking-surprise, everything is still on fire. This week’s highlights reel is a greatest hits album of corporate incompetence, ancient bugs crawling out of the grave, and vendors pretending this is all somehow normal.

First up: a shiny new Microsoft Defender 0‑day. Yes, Defender — the thing that’s supposed to save your sorry ass — apparently tripped over its own shoelaces and face‑planted into exploitable territory. Nothing says “enterprise security” like trusting software that can be turned against you faster than management turns down patching windows.

Then we’ve got SonicWall firewalls getting brute‑forced like it’s 2005 and attackers just discovered password lists. Edge devices exposed to the internet, weak creds, and admins acting shocked when the front door gets kicked in. If you put “admin/admin” on a firewall, you deserve the ransomware bill.

The real crown jewel of this shitshow? A 17‑year‑old Excel RCE bug finally getting attention. Seventeen. Years. Old. This vulnerability is old enough to vote, drink, and laugh at your cloud security posture. Excel spreadsheets — the herpes of corporate IT — once again prove they will never, ever die, and will absolutely take you down with them.

And because one disaster is never enough, the bulletin rounds up 15 more stories involving malware campaigns, supply‑chain stupidity, misconfigured servers, and attackers having the time of their lives because patch management is apparently still optional in 2026.

The takeaway? Patch your shit, lock down your edge devices, stop trusting ancient file formats, and maybe — just maybe — stop acting surprised when attackers do exactly what they’ve been doing for the last two decades.

Now, if you’ll excuse me, this reminds me of the time some genius ran an unpatched Excel macro on the finance server and took down payroll for a week. Management called it “an unfortunate learning experience.” I called it Tuesday.
