Unmasking BLUFFS: Fresh Attacks Undermining Bluetooth’s Trusted Security

New Bluetooth Attacks Undermine Previously Trusted Technology

  • Recent investigations have unveiled several fresh attacks that violate Bluetooth Classic’s promises of forward and future confidentiality, leading to adversary-in-the-middle (AitM) situations amid paired peers.
  • These problems, grouped under the name “BLUFFS,” influence Bluetooth Core Specification 4.2 through 5.4.
  • An identifying label, CVE-2023-24023, aids in tracking these issues, with a CVSS score reflecting a moderate level of threat (6.8).

Discovering Undeniable Sinister Operations in Our Beloved Bluetooth

Think of Bluetooth like your reliable old friend who always came to your rescue when tangled wires were wreaking havoc. However, recent findings have introduced new attacks potentially compelling us to reconsider this decades-long friendship. These attacks defy the forward and future secrecy of Bluetooth Classic, leading to an ‘adversary-in-the-middle’ situation among already associated parties. Now, imagine discovering your friend has been whispering your secrets, that’d be quite the ‘Blue’trayal!

Introducing ‘BLUFFS’ – Bluetooth’s New Enemy

Much like a game of poker, where your overconfident opponent, Bluetooth, just revealed a ‘tell.’ The ‘tell’ we’re talking about here are the issues collectively known as the ‘BLUFFS.’ They impact versions of Bluetooth Core Specification from 4.2 to 5.4. Imagine going through your entire deck of Bluetooth devices to find out they might’ve been ‘bluffing’ you all this time!

Identifying and Evaluating the Risks

Just like having a way to recognize that harmless-looking spider in your garden as a venomous one, these Bluetooth issues come tagged with an identifier, CVE-2023-24023. This identifier lets us track them down more easily. If these attacks were a spice, their CVSS score of 6.8 would make them moderately spicy, something to be mindful of for sure, but not quite the blow-your-head-off strength we’d get from a 10.

In summary, recent research has unveiled new attacks or ‘BLUFFS’ that poke holes in the guarantees of Bluetooth Classic’s secrecy. The affected range is fairly wide (Bluetooth Core Specification 4.2 to 5.4) and their moderate risk threat is indicated by a CVSS score of 6.8. As a result, these findings might give the tech world a bit of a ‘Bluetoothache’ while responding to potential ‘adversaries in the middle.’Original Article: https://thehackernews.com/2023/12/new-bluffs-bluetooth-attack-expose.html
