A scary Bluetooth bug. A crippling ransomware attack. A cyber threat to the U.S. electrical grid. A data leak of trade secrets from major car makers such as Tesla and GM. These were some of the security industry news that caught our eye last week.
Bluetooth vulnerability rattles vendors, end users
The disclosure of a major flaw in Bluetooth last week has sent vendors of all shapes and sizes scrambling to patch their products, including cell phones and computers.
The bug, found by researchers at the Israel Institute of Technology, affects the elliptic curve Diffie-Hellman key exchange mechanism employed by Bluetooth. “The authentication provided by the Bluetooth pairing protocols is insufficient,” they wrote.
The CERT advisory explains that an unauthenticated, remote attacker within range could use a “man-in-the-middle” network position to find out the cryptographic keys used by the device. “The attacker can then intercept and decrypt and/or forge and inject device messages,” it reads.
