In an impactful recent alert, the FBI and CISA urged users to reconsider how they send messages—especially across platforms like iPhone and Android. Here's everything you need to know:
What’s the FBI warning about?
- A cyber-espionage operation named Salt Typhoon, tied to Chinese-state hackers, has infiltrated U.S. telecom networks—stealing metadata and, in some cases, phone call and text data.
- Communications between iPhones and Androids are not end-to-end encrypted, making them vulnerable.
- FBI and CISA are warning users to stop sending traditional SMS/RCS messages, especially across platforms .
Why is this a big deal?
-
Without encryption, SMS and cross-platform RCS can be intercepted, exposing your personal or professional conversations.
Sensitive information, two-factor codes, and personal data can be compromised through these insecure channels .
Top Secure Messaging Alternatives
To stay safe, consider migrating to end-to-end encrypted apps that work seamlessly across devices:
- WhatsApp: Auto-encrypted, widely used, easy to adopt.
- Signal: Non-profit, privacy-focused, and trusted by security experts.
- Telegram: Offers encryption and disappearing messages—additionally warned to be vigilant due to scam activity .
These apps ensure that only you and the recipient can read your messages.
Extra Safety Tips
- Enable automated updates—security patches matter.
- Use phishing-resistant MFA (like hardware keys or Authenticator apps) instead of SMS codes .
- Beware of AI-based scams: the FBI warns about deepfake voice/text attacks. Always verify suspicious calls.
