TL;DR
- Salt Typhoon infiltrated telecom providers in 80+ countries, including virtually every major U.S. carrier.
- Hackers backed by Communist China logged in with stolen credentials instead of “hacking in,” making detection far harder.
- They accessed call records, geolocation data, and police wiretaps, with impacts across energy, transport, healthcare, and government systems.
- Takeaway: If telecom giants can be breached, we all need stronger logins, MFA, updates, and skepticism.
🌐 What Happened
In 2024, a Communist China–backed group dubbed Salt Typhoon carried out one of the largest telecom hacking campaigns in history. Investigators found compromises across dozens of countries, impacting not just carriers but also supply chains, energy, transportation, healthcare, and sensitive government systems.
🔓 How They Got In (Hint: They Logged In)
- Valid accounts: Attackers used stolen usernames and passwords—a pattern IBM calls “hackers don’t break in, they log in.”
- Infostealers & phishing: A surge in emails distributing infostealer malware produced a flood of credentials for sale and re-use.
- Unpatched edge devices: Vulnerabilities in networking gear (e.g., VPN gateways, firewalls) gave quiet footholds when left unpatched.
- Hiding in plain sight: Once inside, adversaries “lived off the land,” blending with normal traffic and using cloud infrastructure to mask command-and-control.
📞 What Was Stolen
- Call and text metadata (who, when, where) for ordinary users and high-value targets.
- Geolocation traces at scale.
- Wiretap visibility—in some cases, access to systems used for lawful intercepts.
- Credentials & network maps from sensitive environments, enabling persistence and expansion.
⚠️ Why It Matters
- National security risk: Communications patterns of leaders, agencies, and companies can be profiled at scale.
- Civilian exposure: Ordinary people’s records are swept into large datasets—useful for scams, blackmail, or tracking.
- Critical infrastructure: Pre-positioning inside telecoms makes later disruption of energy, transport, and health systems easier.
✅ What You Can Do (Everyday Protection)
- Use strong, unique passphrases (no reuse across accounts).
- Turn on Multi-Factor Authentication (MFA) everywhere you can.
- Update devices and apps—automatic updates close the exact holes attackers seek.
- Be cautious with links & attachments—infostealers often arrive via email or drive-by download.
- Report suspicious activity to the Canadian Anti-Fraud Centre.
