One of the most interesting sessions was from a hacker calling himself Renderman, who revealed - amongst other tings - how most people are at risk of a security breach, but are blissfully unaware of it.
According to Renderman, the problem stems from the use of default passwords on Bluetooth and WiFi devices.
The situation is so bad, he said, that he recommends peeps turn off their WiFi or Bluetooth-enabled devices when not in use. As well as changing the default password.
Interestingly, Renderman says that it's even possible to remote scan a new-style US passport with its passive RFID chip.
The US government, he said, has attempted to reduce the problem by placing a metal foil layer on the front and back cover of the passports, but the stiffness of the foil pop the passport open, allowing hackers sideways access to the chip.
"There is no rule that says that if the chip doesn't work, they will refuse you access to the border. You will get increased scrutiny, but it's still a valid document," he said.
Sounds a bit drastic - disabling the chip on a US passport. You could always wrap it in a foil packet, but then the INEA guys will think you're a nutter.
Mind you, which would you rather be - a safe nutter or an insecure upstanding member of the US community?...
