This is the community for all things hacking and cybersecurity, try keeping it legal. That said I don't take any responsibility for anything that happens/comes from this group but I will try being the best mod that I can to prevent anything from happening.

Hey everyone yesterday I was at a grocery store and I noticed suspicious WiFi networks and Bluetooth networks. I am quite tech savvy so I decided to investigate thinking it was probably just some skid. But when I opened Wireshark I saw the mac addressees for Cisco Merkari (A relatively advanced DPI program) , along with multiple other enterprise grade tools such as Fortinet and VMware. I have collected pcaps for both my Bluetooth and WiFi interfaces with Wireshark(available upon request). Does anyone have any idea could this be a government contractor? Or could it just be spoofed cause its relatively easy to spooph Mac addresses.

Yeah, VMWare is an enterprise platform, so I'd be pretty surprised if they weren't using it. It's a grocery store so I can't imagine they have huge throughput needs in the first place, but even then VNWare networking appliances are super common. We use them where I work to support thousands of users in office environments. As for the Bluetooth, again just guessing but they either don't support broadcast being turned off, or more likely they MSP/central IT just didn't disable it because they didn't care/don't know how. I think you're vastly overestimating how much effort went into the network setup for a grocery store.

Definitely a good point and I could be over thinking it. Personally I'm a Hobbyist who is not yet complete with the education to enter the industry, So you definitely know more than me . Do Cisco routers ever randomize there bssid, cause looking at the pcap files the Mac addresses of completely different vendors even competetitiors like ubiquity are all using spectrum network handles could this be a clusterfuck of different routers or just a Cisco cluster randomizing there bssid?
