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.

Risks in IoT Supply Chain

Unit 42 analyzes multilayer IoT supply chain risks across hardware, firmware, and software, citing counterfeit Cisco switches and OpenWrt attacks.

Unit 42 examines weaknesses in the IoT supply chain ecosystem across hardware, firmware, operation, and vulnerability layers, noting that 89% of IT decision-makers reported IoT device growth and IDC forecast 41.6 billion connected IoT devices by 2025. Examples include counterfeit Cisco Catalyst 2960-X switches with possible backdoor access (F-Secure, July 2020), a March 2020 OpenWrt flaw enabling malicious update impersonation, and threat actor interest in TeamViewer remote support software. The report stresses that untracked third-party components and missing device inventories make it hard to assess vulnerability impact across vendors.

8,539 Reasons To Rethink How Vulnerabilities Get Patched

Rapid7 counted 8,539 high and critical CVEs in Q2 2026, double last year, with PoC availability up 76%.

Rapid7's Q2 2026 Threat Landscape Report tallied 8,539 high- and critical-severity vulnerability disclosures, twice the number recorded in Q2 2025, with newly disclosed flaws having public proof-of-concept code up 76% year over year. Of newly exploited vulnerabilities, 62% were network-exploitable and required neither authentication nor user interaction. Fake CAPTCHA and ClickFix social engineering accounted for 31.8% of incident response cases, the United States recorded 881 listed ransomware victims, and APT28 exploited SOHO routers for DNS hijacking while Iranian groups targeted US industrial control and OT systems.

MacOS 27 - First Boot, (Tue, Sep 15th)

SANS ISC documents the expected network traffic macOS 27 'Golden Gate' generates on first boot to help defenders baseline their networks.

Johannes Ullrich of SANS Internet Storm Center captured roughly 300 packets from a macOS 27 'Golden Gate' system before user login, covering DHCP, IPv6 duplicate address discovery, DNS, and TCP behavior. macOS 27 resolves hostnames like albert.apple.com (device activation, certificate-pinned), push messaging hosts, and ipv4only.arpa for NAT64 networks. The OS still uses a TCP window scale of 6, ECN, and random timestamps, with only four TCP connections observed during boot. The analysis provides a reference baseline for security teams monitoring Apple endpoints.

BGP Role model: tracking the adoption of RFC 9234

Cloudflare measured RFC 9234 adoption, finding BGP Role deployment growing but two Tier 1 networks unexpectedly stripping the Only to Customer attribute.

Cloudflare analyzed adoption of RFC 9234, which introduces BGP Roles and the Only to Customer (OTC) attribute allowing routers to reject route leaks on their own. The measurement study assessed who has deployed the mechanism in the global routing table. It found two Tier 1 networks unexpectedly stripping OTC attributes, which could undermine leak protection.
