David Tinley, a former Siemens contractorAdmitLogical bombs were planted in spreadsheets created for employers, who would face up to 10 years in prison and a fine of $250,000. Logical bombs can cause spreadsheets to crash after a specific date, and Siemens needs to hire the contractor again to fix the problem, and he charges a fee for each fix.
Tinley, who has served Siemens in Monroeville for nearly 10 years, was asked to create spreadsheets for the company to manage orders, including custom scripts that can update files based on current orders stored in other documents, allowing the company to automate inventory and order management. His spreadsheet worked well for many years, until problems began to emerge in 2014.
The logical bomb he planted caused the spreadsheet to crash after a certain date. Every time it crashes, Siemens contacts him to fix it, and he charges for it.

SIEMENS IT employees found the logical bomb and the situation changed sharply. Tinley was charged in May, pleaded guilty last week, and a sentencing hearing will be held in November.
