VAR-201809-0750

Vulnerability from variot - Updated: 2024-11-23 22:51

A Pektron Passive Keyless Entry and Start (PKES) system, as used on the Tesla Model S and possibly other vehicles, relies on the DST40 cipher, which makes it easier for attackers to obtain access via an approach involving a 5.4 TB precomputation, followed by wake-frame reception and two challenge/response operations, to clone a key fob within a few seconds. Pektron Passive Keyless Entry and Start (PKES) There are cryptographic vulnerabilities in the system.Information may be tampered with. The Tesla Model S is an electric car produced by Tesla. The PKES system used in the Tesla Model S and other devices has a security flaw that stems from the fact that the PKES system relies on the DST40 cipher. An attacker could exploit this vulnerability to clone car keys in seconds
