How a USB-connected speaker can infect a PC without ever being touched

A researcher discovered a vulnerability in the Sound Blaster Katana V2X speaker that allows a Bluetooth device to connect to a PC via USB without authentication or pairing. The Creative Transport Protocol (CTP) used by the speaker enables commands like changing LED colors and equalizer settings, as well as uploading new firmware without security measures. This flaw could potentially lead to remote code execution on the targeted device, highlighting a security risk in USB-connected speakers.

NSA using Claude Mythos for 'offensive cyber operations,' report claims — says 'half-a-dozen' Anthropic engineers embedded inside the agency

The National Security Agency (NSA) is reportedly utilizing Anthropic's cybersecurity-focused Mythos model for "offensive cyber operations," with several Anthropic engineers embedded within the agency. This move aims to gain an advantage over adversaries who may also be using similar AI models. Despite Anthropic being banned from providing services to the Department of Defense (DOD), the engineers are assisting in customizing Mythos for specialized cyber-attacks. The situation stems from a dispute between Anthropic and the DOD over the use of AI for various purposes, leading to Anthropic being labeled a supply chain risk. The ongoing legal battle between Anthropic and the DOD adds complexity to the situation, raising questions about the future of their relationship.

Outlook may have allowed unencrypted connections for decades, report claims — Fedora and Dovecot upgrade reveal protocol downgrade issue present since at least 2007

An IT blogger discovered a significant security vulnerability in Microsoft Outlook where SSL/TLS connections were being downgraded to unencrypted plaintext without user notification. This issue affects Outlook versions from 2007 to 2016, potentially even later versions. The problem was uncovered during a mail server upgrade from Fedora 42 to Fedora Server 43, causing errors for users with the "Use TLS/SSL" checkbox enabled in Outlook. The issue stems from a protocol downgrade triggered by selecting port 110 and using the POP3 protocol, leading to unencrypted email retrieval for over a decade. The recent Dovecot upgrade in Fedora Server 43 revealed this behavior, emphasizing the importance of ensuring encrypted connections for email security.
