A week in security (August 19 – 25)

Last week on Malwarebytes Labs, we reported on the presence of Magecart on a type of poker software; outlined how the Key Negotiation of Bluetooth KNOB attack works; followed the money on a Bitcoin sextortion campaign; looked back at DEF CON 27; and reported on continuing ransomware attacks on...

Bluetooth vulnerability can be exploited in Key Negotiation of Bluetooth (KNOB) attacks

Those who are familiar with Bluetooth BR/EDR technology aka Bluetooth Classic, from 1.0 to 5.1 can attest that it is not perfect. Like any other piece of hardware or software technology already on market, its usefulness comes with flaws. Early last week, academics at Singapore University of...

Code injection

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks aka "KNOB" that can decrypt traffic and inject arbitrary...

New Bluetooth Vulnerability Lets Attackers Spy On Encrypted Connections

Over a billion Bluetooth-enabled devices, including smartphones, laptops, smart IoT devices, and industrial devices, have been found vulnerable to a high severity vulnerability that could allow attackers to spy on data transmitted between the two devices. The vulnerability, assigned as...

Bluetooth BR/EDR supported devices are vulnerable to key negotiation attacks

Overview The encryption key length negotiation process in Bluetooth BR/EDR Core v5.1 and earlier is vulnerable to packet injection by an unauthenticated, adjacent attacker that could result in information disclosure and/or escalation of privileges. This can be achieved using an attack referred to...
