[Sentinel] #14 - Salesforce Breach Exposes Millions!

OAuth token theft hits Salesforce & more—get critical lessons and free tools to stay secure.

September 05, 2025

Hello Cyber Guardians! 🛡️

Your weekly cyber rundown is here! 😎

🧨 1. Breach of the Week

Target: Salesforce & Ecosystem

Salesforce, Cloudflare, Zscaler, Palo Alto Networks, Farmers Insurance were breached when attackers hijacked OAuth tokens through a malicious Salesloft integration. This pivot let them empty massive customer support cases, leaking millions of records and secrets. Example: Cloudflare impact farmers Insurance lost data on 1.1M people, TransUnion on 4.4M.

Vector: OAuth Token Theft - Attackers exploited weak auth flows between Salesloft AI plugins and connected services.

Impact: Multi-million Exposure - Support cases and embedded credentials were harvested at scale.

Lessons

  • SaaS integrations amplify risk. Beware of linking critical systems without strong controls.

  • Never put secrets in support tickets. Assume ticketing systems will be targeted in future breaches.

🧠 2. AppSec

It’s a week of urgent exploits and weaponized vulnerabilities:

  • WhatsApp fixed a “zero-click” bug for iOS/macOS used in elite spyware

  • SAP saw RCE exploits released for two critical vulns

  • Fresh flaws hit Sitecore, Tableau, Atlassian, Chrome

📍 Takeaway: Patch new vulns with urgency. Attackers are prioritizing these CVEs for initial access. Delay means exposure.

☁️ 3. CloudSec

Stolen OAuth tokens let attackers comb through Salesforce tenants and swipe cloud secrets. Including AWS keys (Salesforce token theft). Support logs at Cloudflare and Zscaler were breached, leaking credentials. Ransomware crews now delete cloud backups to amplify pressure.

📍 Takeaway: Token rotation, privileged access, and minimal support data are critical for SaaS and cloud defense.

📡 4. Attack Surface

Cloudflare stopped an all-time high 11.5 Tbps DDoS blast. RDP brute-force and AI-powered phishing surged across public attack targets.

📍 Takeaway: Stay on top of exposure. Lock down public interfaces, monitor for rapid attack pivots, and expect more creative, automated threats each week.
