We have an application that scans documents and lets the employee see them on the screen. If they are OK they click a button and the app submits the document as a PDF file directly to an OnBase document repository. There is no disk file or temporary file at all. The PDF is written on the fly. Onbase can store any type of file and it happily stored them without any errors being displayed.
Later on people are opening the PDF files from the document repository and they won't open because they are corrupted. Looking at one in Notepad shows it's full of nothing but null characters. And since OnBase creates the file names automatically in sequence, we can't just re-scan the originals and have them go in the correct place to replace the corrupted ones.
And since SAV/SEP silently corrupted the PDF's being written on the fly, we really have no idea how many or which ones we need to fix without going through every one, and there are hundreds from just today.
This is going to take days to straighten out. We've never had a virus outbreak that caused this much damage to productivity and operations.
