Proximity access cards are no more secure than a standard key .. and easily replicated with a $10 (to be released) tool. This was shared on ZDNet and with Motherboard. I have highlighted 2 key sections below for those interested in greater detail definitely check out the article. If you are lucky enough to see the presentation live at BlackHat, that will surely be better.
While RFID technology can help secure enterprise offices in this way, the ease in which these access controls can be hacked has hit the spotlight in the form of a tiny device which costs only $10 to make.
Researchers Mark Baseggio from security firm Accuvant and Eric Evenchick from Faraday Future are the developers of the Bluetooth Low Energy device (BLEKey), a coin-sized device which skims RFID cards, allowing users to clone items such as access cards.The team says the release of the tool is “valuable for understanding the risks associated with insecure access controls and what steps companies can take to lower the risk of access control attacks.” – ZDNet Article
I would raise the point that these attacks can now be down so easily that can the “control” of access control physically be fully trusted from a third party assurance perspective, an industry perspective such as PCI, or risk management? One could argue that cameras support this protection, but those are only employed after damage has been discovered and insufficient for all of the stakeholders involved.
“We wanted to create a device that would concretely and absolutely show and hopefully put the final nail in the coffin that is HID prox and Wiegand. These devices are no more secure than a standard key.” – Motherboard, Baseggio
The difference though with a ‘standard key’ is that takes some crafty spy work to make a copy without the owner being aware. To copy a HID card would take only seconds – at a gym, lanyards left at a desk, etc …
Glad the research cycle is exposing these risks and looking forward to creative approaches to counter it.
