VU#756733: Calix GS7 XGS GS5239XG residential router contains missing authentication vulnerability

CERT/CC warns Calix GS7 XGS GS5239XG routers on firmware EXOS/6.6.47 expose an unauthenticated UPnP WANIPConnection service on the public WAN interface.

CERT/CC issued VU#756733 for a missing authentication vulnerability in the Calix GS7 XGS GS5239XG residential gateway running EXOS/6.6.47. The device's UPnP service, implemented with MiniUPnPd 2.3.7, is exposed on the WAN interface by default and does not require authentication, potentially letting remote attackers alter port mappings through the WANIPConnection service. The flaw affects routing, NAT, and firewall functionality for home networks.

Skullcandy Dime 3 earbuds expose users to Bluetooth hijacking

CERT/CC warns Skullcandy Dime 3 earbuds accept silent Bluetooth pairings via CVE-2025-20701, letting nearby attackers hijack audio and microphone.

CERT/CC reports the Skullcandy Dime 3 (model S2DCW) running firmware 1.0.0.28 is affected by CVE-2025-20701, a high-severity missing-authentication flaw in the Airoha Bluetooth Audio SDK. An attacker in close range can pair without user interaction, then hijack audio playback, access the headset profile, and capture live microphone audio. Skullcandy fixed the issue in firmware 1.0.0.30, but existing units have no consumer-accessible update path via the app. The flaw was discovered by ERNW researchers and affects earbud and headphone products from multiple vendors; Apple patched it for Beats Studio Buds in June.

Inside Knight Office, a New M365 AiTM Phishing Kit

Huntress details Knight Office, a new AiTM phishing kit stealing Microsoft 365 session tokens and registering attacker-controlled devices.

Huntress investigated an August 18, 2026 adversary-in-the-middle attack using the Knight Office phishing kit, which captured Microsoft 365 session tokens via a DocuSign-style lure routed through a Monday.com tracking link and a compromised Joomla site. After token capture, the actor enrolled an unauthorized host in Microsoft Entra ID and bound a Windows Hello for Business key credential to the account. The kit's operator console, found at IP 104.37.188.94, is built on Python Flask and hosts at least 25 .vu phishing domains. Telemetry links the kit to at least nine token-replay logins in two weeks and roughly 700 reported lure emails since April.

New N0va Phishkit Targets North America and EU: A Growing Identity Risk for SOCs

ANY.RUN researchers uncovered the N0va phishkit targeting government, technology, consulting, and healthcare organizations across North America and the EU via device code phishing.

The N0va phishkit uses lures imitating Microsoft Teams, SharePoint, OneDrive, DocuSign, Google Drive, Dropbox, Zoom, and Adobe Sign to draw victims into a device code authentication flow. After the user completes legitimate authentication, N0va captures access and refresh tokens and abuses token-exchange and device-registration mechanisms to establish persistent SSO access to corporate resources. Because the flow relies on real Microsoft authentication, it can evade MFA-focused detections, and token access can outlive takedown of the phishing page. ANY.RUN says it observed the campaign in sandbox sessions, with targeting spanning government, technology, consulting, and healthcare sectors.
