I want to know the answer to the following question:
What was stolen from Target Corporation computers in 2013?
All the background I'm provided with is that ""The malware utilized is absolutely unsophisticated and uninteresting," says Jim Walter, director of threat intelligence operations at security technology company McAfee – meaning that the heists could have easily been stopped by existing antivirus software had administrators responded to the warnings.". Is that enough to answer the question?
