Hacking Public Wi-Fi DNS to Steal Credentials

Attackers can hijack public Wi-Fi DNS to redirect users to credential-stealing fake login pages; commenters debate HTTPS limits and mitigations like encrypted DNS.

The discussion examines how an attacker controlling DNS on shared or public Wi-Fi networks can redirect requests for legitimate services to attacker-controlled servers to steal credentials. Commenters analyze whether HTTPS and certificates mitigate the attack, noting attackers often rely on HTTP or browser trust quirks. Suggested defenses include encrypted DNS (DoH), DNSSEC, and travel routers running OpenWRT. No specific campaign, victims, or indicators are provided.

Skullcandy Dime 3 Bluetooth Flaw Lets Nearby Attackers Hijack Audio and Microphone

CERT/CC disclosed VU#859658: Skullcandy Dime 3 earbuds on firmware 1.0.0.28 accept unauthenticated Bluetooth pairing, letting nearby attackers hijack audio and microphone.

Skullcandy Dime 3 wireless earbuds (model S2DCW, firmware 1.0.0.28) accept Bluetooth Classic BR/EDR pairing requests from unknown devices without the owner activating pairing mode, a flaw linked to CVE-2025-20701 in Airoha Bluetooth audio SDK implementations and tracked as VU#859658 by CERT/CC. Attackers within Bluetooth range who know the device address can bond via the NoInputNoOutput configuration, establish A2DP or HFP/HSP connections, disrupt the owner's active audio session, and potentially capture live microphone audio. Firmware 1.0.0.30 addresses the issue, but Dime 3 earbuds do not support firmware updates through the Skullcandy mobile app, leaving affected users without a known upgrade path.

VU#369611: ExLlamaV3 contains Denial of Service vulnerability via insufficient bounds checking on kernel dispatch index

CERT/CC details CVE-2026-84286, an out-of-bounds memory access in ExLlamaV3's CUDA extension causing denial-of-service crashes; fixed via merged pull request.

CERT/CC published VU#369611 for CVE-2026-84286, an out-of-bounds memory access in the exllamav3_ext CUDA extension of the ExLlamaV3 LLM inference library. A crafted input with kernel parameter K set to 0 produces a negative index into a fixed 24-entry kernel dispatch array, causing a CUDA illegal memory access and denial-of-service crashes. The vendor fixed the issue in the main repository via pull request #310, and maintainers of 49 downstream projects, including ezexl3 and MawDiscord, are advised to rebuild against the patched version. The issue was reported by Nathan Keys and impact is limited to crashes and instability, not code execution.

Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.

Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.
