One of my office locations is in a busy area of Washington, DC with the usual dozen or so wifi hotspots available. The other day, I noticed a few new open ones: TWCWiFi, optimumwifi and xfinitywifi. All are ostensibly free wifi from cable companies… here’s the trick though: two of them don’t do business in DC. Turns out these are likely phishing wifi spots trying to lure the noneducated surfer into coughing up some bank passwords. Memo to the wise: beware of public free wifi that you can’t confirm is for real!
