A story we hear too often
The night shift at a 40-person machine shop finds the quoting server locked
the second-generation owner of a job shop in Elk Grove Village
Dan’s father started the shop with two Bridgeports in 1987. Today it is 40 people, six CNC cells and a quoting system that knows every part they have ever cut. The shop runs a second shift because the customers in medical devices and food equipment want parts Thursday, not next week.
At 11:20 on a Tuesday night the lead machinist calls Dan at home. The quoting server is showing a ransom note. The shared drive with thirty years of drawings, fixtures and CMM programs is renaming itself file by file. The controllers on the floor still run, for now, because the same network carries the office and the machines.
The note asks for a sum that is roughly the shop’s profit for the year. It is the moment every owner imagines and never plans for. In the version that ends badly, the backups sit on the same network and are already encrypted, the customer files go up on a leak site and the medical-device customer suspends the supplier.
In Dan’s version, the protection agent isolated the quoting server at 11:04, sixteen minutes before the call, and the engineer on watch is already restoring drawings from the offline copy. First shift starts on time. Dan spends the morning deciding which customers to tell, not whether the company survives.

What changes the ending
- Offline, tested backups of drawings, programs and the quoting database, restored on a schedule (CIS Control 11, Data Recovery)
- The machine network separated from office email and browsing (CIS Control 12, Network Infrastructure Management)
- Patching the remote-access and ERP software attackers exploit first, with someone watching for the exploit (CIS Controls 7 and 13)
