👋 Intro
Welcome toThe CyberSignal — your trusted source for clear, actionable cybersecurity news. Every Tuesday, we recap the most important events from the past week — from breaches and zero-day exploits to policy shifts and industry insights.
This isn’t just about what happened. It’s about what you, as a CISO, IT professional, or security leader, need to do next.
🔍 Overview: What Shifted in Cyber Last Week
Android in crisis mode — 84 vulnerabilities patched, including two zero-days already exploited in the wild. (Tom’s Guide)
Samsung’s zero-day patched — CVE-2025-21043 allowed attackers to hijack devices via image parsing. (SecurityWeek)
Ransomware leak in New Orleans — Qilin gang publishes 842 GB of sheriff’s office data. (Axios)
Jaguar Land Rover production shutdown — disruption extended until September 24 after cyberattack. (Reuters)
Texas breach — nearly 44,500 disaster grant applicants’ data exposed due to system misconfiguration. (Express News)
🔝 Key Incidents & Analysis
Android’s Double Zero-Day Patch Push
Google’s September update fixed 84 vulnerabilities, including CVE-2025-38352 and CVE-2025-48543, both of which had active exploits in the wild. Meanwhile, Samsung’s patch for CVE-2025-21043 addressed a critical bug in its libimagecodec.quram.so library that enabled remote code execution.
👉 Why it matters: If you manage fleets of Android devices, delay in patching = exposure. Prioritize urgent OS/hardware patches and enforce auto-updates across the board.

Qilin Ransomware: Local Government in the Crosshairs
The Qilin gang is now selling data stolen from the Orleans Parish Sheriff’s Office after a ransomware incident. The leaked content (842 GB) includes court docket systems, disrupting local operations and public trust.
👉 Key takeaway: Local governments often lag in cyber posture. Incident response, data backup, and public communications must be ready — not only to recover systems but to maintain confidence.
(Axios)
Jaguar Land Rover: Disruption in Manufacturing
Jaguar Land Rover has extended its production halt until September 24 due to the fallout from a cyber incident. Financial and supply chain ripple effects remain unclear.
👉 What C-suite should watch: Cyber risk for physical production is real. Build redundancy, assess vendor risk, and ensure your OT/IT boundaries are hardened.
(Reuters)
Texas Grant System Breach: Misconfigurations Bite
A misconfiguration in Texas Integrated Grant Reporting exposed sensitive data for nearly 44,500 grant applicants spanning almost a decade (2015-2024). Data included Social Security numbers, bank info, and medical details.
👉 For IT teams: Configuration errors remain one of the most frequent breach vectors. Implement config management, routine audits, and least-privilege access even in internal systems.

⚠️ Threat & Vulnerability Highlights
Threat / CVE | Summary | Risk to You |
|---|---|---|
Samsung Android Zero-Day (CVE-2025-21043) | Actively exploited bug in image codec allowing remote code execution. | Devices running Android 13-16 at risk. Patch immediately. |
Google Android Bulletin | 84 issues patched, incl. 2 zero-days under active attack. | Broad fleet risk. Apply patches ASAP and monitor. |
🛡️ Actionable Tips for CISOs & IT Leaders
Elevate Patch Strategy — Prioritize zero-day and high-CVSS patches, especially on mobile endpoints.
Audit Configurations — Misconfigurations = breaches. Automate checks and track drift.
Plan for Ransomware Disclosure — Prepare a comms plan before attackers do it for you.
Harden Supply Chains — Vendors and OT/IT links are weak points. Ensure segmentation and monitoring.
Fleet Management — Require auto-updates, enforce device compliance, and watch patch adoption metrics.
🏛️ Legislative & Regulatory Changes
DoD’s CMMC 2.0 Final Rule — effective Nov 10, 2025. Contractors will need to meet new tiers of cybersecurity compliance. (Holland & Knight)
House NDAA Bill — adds AI & SBOM requirements for defense tech. (CyberWire)
Cybersecurity Information Sharing Act renewal debate — liability protections for companies sharing intel may expand. (WSJ)
State-level packages — 19 states passed 28+ cyber bills in 2025, covering breach notifications, IoT, and workforce development. (NCSL)
👉 Why it matters: Compliance is becoming as critical as patching. Map your legal obligations early and budget for audits.
💡 Quick Hits
M&S Chief Digital Officer resigns following their earlier 2025 cyberattack — accountability matters at the top. (TechRadar)
Research on governance gaps finds human error + weak oversight are still driving major breaches. (arXiv)
A massive DDoS attack in Western Europe peaked at 1.5 billion pps before being mitigated. (Cybersecurity Review)
🔭 Looking Ahead
Expect closer scrutiny on app/image libraries after Samsung’s CVE-2025-21043.
Qilin ransomware tactics may spread; more leaks expected.
Watch for new Android zero-day disclosures as chip-level research ramps up.
Regulatory deadlines: CMMC compliance prep needs to start now.
🚀 Pro Tip of the Week
Set alerts for unusual outbound traffic from “quiet” systems (local gov portals, grant systems, legacy databases). Misconfigurations often go unnoticed — until attackers find them first.
🔒 Conclusion
The past week showed cyber risk at every layer — from Android endpoints and SaaS integrations to manufacturing plants and local government systems. Attackers continue to exploit the simple (config errors) as much as the complex (zero-days).
👉 For CISOs and IT leaders: patch aggressively, audit continuously, and never underestimate small systems or forgotten integrations.
