Android 17 adds new protections against sneaky Wi-Fi tracking and web snooping
Android 17 adds Encrypted Client Hello, Local Network Protection, default Certificate Transparency and operator-controlled 2G disabling to counter Wi-Fi tracking and snooping.
Google announced network security changes in Android 17, led by broad support for Encrypted Client Hello (ECH), which encrypts domain names visible to network operators and eavesdroppers, paired with GREASE decoys where server support is uneven. Jigsaw testing across the top 10,000 domains and 740 ISPs in 202 countries found connection success and interference levels comparable to ordinary TLS. Android 17 also adds Local Network Protection requiring app permission to scan local devices, Certificate Transparency on by default to catch forged certificates, and operator-side 2G disabling to cut exposure to SMS blaster fake base stations. Apps targeting Android 17 get ECH by default via networking libraries such as OkHttp, WebView and HttpEngine.

Who’s Tracking You? Use This New Service to Find Out
KrebsOnSecurity covers DecryptAds, a free service that scrapes and correlates adtech data to reveal which entities track users across sites and apps.
KrebsOnSecurity wrote about DecryptAds, a free service that scrapes and correlates adtech data. The service makes it simple to identify which entities are responsible for ads shown on websites and data harvested by mobile apps, information that is semi-public but traditionally walled away inside large advertising platforms. No security incident is involved; the piece is an introduction to a privacy-research tool.

Honeypot-Omaha and batch.py [Guest Diary], (Wed, Sep 2nd)
A SANS ISC guest diary describes batch.py, a Python tool that consolidates honeypot logs and enriches IOCs with threat intelligence data.
Written by a SANS.edu BACS intern, the diary explains analysis of the DShield Honeypot-Omaha sensor, which uses Cowrie to emulate SSH and Telnet and log attacker activity. The author's batch.py script implements a four-phase pipeline with SHA-256-generated master and guest authentication to consolidate JSON and log files, correlate data via external APIs, and produce MITRE, CVE, geolocation, threat-score and fingerprint enrichment for investigated indicators.

Homebrew 7.0.0 Adds Built-In Vulnerability Scanner and Stronger Package Sandboxing
Homebrew 7.0.0 ships a native brew vulns scanner, OSV-backed advisory database, stronger sandboxing, and fixes a sandbox-escape issue.
Homebrew 7.0.0 introduces a built-in 'brew vulns' command that scans installed formulae, dependencies, and Brewfiles against a new Homebrew-specific advisory database and OSV.dev data, distinguishing backported fixes from outdated versions. The release hardens sandboxing by blocking home-directory reads during builds, disabling network access at install time, and replacing Bubblewrap with Landlock on Linux. It also fixes moderate-severity GHSA-5263-whxq-77hp, where a malicious cask could execute code outside the macOS sandbox via LaunchServices, and drops macOS Catalina while moving Intel Macs to Tier 3.

Keepnet released the free SMS/Call Reporter app for iOS, letting users report suspicious SMS and voice phishing with one tap. For enterprise customers, reports flow into Keepnet Incident Responder alongside email phishing reports. The company cites Verizon 2026 DBIR data showing mobile phishing simulations achieve a 40% higher median click rate than email, and FBI IC3 2025 counted $798 million in smishing and vishing losses. An Android version is planned.

CBTS brings continuous penetration testing to enterprise security
CBTS launched Penetration Testing as a Service built on Horizon3.ai's NodeZero, combining autonomous pentesting with expert review for continuous validation.
CBTS announced PTaaS, a service that runs recurring autonomous penetration tests powered by Horizon3.ai's NodeZero across cloud, SaaS, identity, and AI environments, with CBTS experts reviewing findings for exploitability and remediation guidance. The service supports daily-to-quarterly cadences and aims to support Continuous Threat Exposure Management (CTEM) programs. It cites Verizon's 2026 DBIR finding that re-exploitation likelihood drops roughly 30 days after last observed exploitation.

Have it both ways: stay discoverable in search while disallowing AI training
Cloudflare launches Disallow AI Training setting letting sites block AI training via robots.txt while staying indexed in search; Apple, Google, and Microsoft honor it.
Cloudflare announced a 'Disallow AI Training' setting that publishes a no-training preference in robots.txt so sites can block AI training (including by mixed-use crawlers) without losing search indexing. Apple, Google, and Microsoft meet Cloudflare's new 'Accountable' designation, which requires training/summary opt-out mechanisms, URL-level training visibility, and assurance that opt-outs don't affect search rankings. Cloudflare cites that under 1% of its sites block search bots while 17% block AI training, and its Block settings now apply to mixed-use crawlers as well. Granular controls over how much content appears in AI summaries are planned for early next year.
