Recommended precautions include:
: Maintain a secure, encrypted database of all PLC passwords, accessible to authorized maintenance personnel only. The tools work by reading raw sector data

If you are locked out of a Simatic PLC, consider these safer recovery paths:
Around September 2006, various utilities like s7ImgRd (image reader) and s7ImgWr (image writer) became popular in technical forums for bypassing security. These tools allowed users to:
