How's this different than normal?
By the time a company is liquidated, anybody left there gives zero ***cks to what happens to anything left over, data, sensitive info, etc?
I've cleaned out offices with tax forms, W-2's, etc. all left behind. This is normal.
I've also bought 2nd hand filers from liquidated companies with full data still left on them. Source code, CAD drawings, records, etc. etc. Bought network gear with full configs (SNMP communities are always fun) still left on them, etc.
Not many liquidators would have the means, knowledge or time to make sure things are securely wiped, and if it has come down to the end, its doubtful anybody still left at a company does either. They are the cleanup crew, get it out, get it gone. who cares.
