I believe I was also a victim of being hacked via Bestbuy. I purchased a open box PC, geek squad in Melrose Park was supposed to wipe the PC.
I own a business and gave them my business card since I didn't have time to wait. As soon as my IT professional hooked up the computer to our business remote server, the hacker accessed everything via remote. My personal information and he or she attempted to access much more. I had to replace every hard drive in my office and wipe the PC purchased.
We are still going through forensics on the hard drives.
This was the bestbuy in Melrose Park, IL. Clearly buying a open box PC is never worth the risk.
