[Sentinel] #2 - 184 million login credentials exposed

API keys, unencrypted GCP storage, and nearly 900K users exposed—what went wrong and how to prevent it.

June 12, 2025

Hey Security-Minded Reader 👋

You’re reading the very first issue of this newsletter—a new dispatch at the intersection of cybersecurity and artificial intelligence.

If you care about breaches, AI-driven threats, security protocols, and how all of it is evolving faster than regulators or legacy systems can keep up—you're in the right place.

🛡️ IN TODAY’S EDITION

🧨 1. Breach of the Week

  • Target: Google & Apple (plus Microsoft, Facebook, Instagram, Snapchat, and others)

  • Vector: Unprotected database exposed 184 million login credentials

  • Impact: 184,162,718 unique usernames and passwords leaked

Lessons:

  • Infostealer malware remains a massive threat, siphoning credentials and sensitive browser data from infected devices

  • Databases containing sensitive information must be encrypted and access-controlled—no exceptions

  • Users should regularly change passwords, enable multi-factor authentication, and avoid storing sensitive documents in email inboxes

🧠 2. AI Accelerates Government App Breach

Hackers breached TeleMessage—a Signal-based app used by US officials—by exploiting AWS misconfigurations to steal admin credentials and government communications data.

💡 AI-powered reconnaissance tools are shrinking the attack window, automatically scanning for exposed cloud assets faster than defenders can patch them.

📉 Even encrypted messaging apps fall victim when backend infrastructure lacks proper security.

📍Takeaway: AI-driven attacks require AI-powered defenses and automated monitoring.

🔒 3. Protocol News: CISA AI Security Guidance

CISA and international partners released fresh guidance this May for securing AI systems from training to deployment.

💡 Key focus: data supply chain security—protecting the data that feeds AI models from tampering and unauthorized access.

📉 Addresses critical risks like malicious data modification and "data drift" that can silently corrupt AI performance over time.

📍Takeaway: Review your AI deployments now—especially access controls, logging, and data integrity measures.

📡 4. Attack Surface: IoT & Cloud

Recent breaches (Mars Hydro, TeleMessage) reveal how sprawling modern attack surfaces have become:

💡 IoT devices like hydroponic controllers leaked billions of records—Wi-Fi passwords, IP addresses—due to terrible security defaults.

📉 Cloud misconfigurations get exploited within minutes by automated bots scanning 24/7 for vulnerabilities.

🔓 Even "secure" messaging platforms crumble when backend controls are weak.

📍Takeaway: Every device, API, and cloud bucket is now an endpoint. Harden them with perimeter-level rigor.
