Recent revelations about large-scale cyberattacks by Chinese hackers, dubbed “Salt Typhoon,” have escalated concerns about the security of U.S. telecommunications. The FBI and CISA (Cybersecurity and Infrastructure Security Agency) are now urging Americans to prioritize encrypted messaging and calls to safeguard their privacy.
The Threat at Hand
Salt Typhoon, a hacking group linked to China’s Ministry of Public Security, has reportedly breached multiple U.S. telecom networks. This campaign, which began earlier this year, targeted critical infrastructure and compromised private communications—particularly of individuals in government or political roles.
Although the attackers stole call and text metadata, widespread access to the actual content of messages or calls has not been confirmed. However, sensitive communications were accessed in limited cases, raising alarm over national security.
Encryption as the Best Defense
The FBI emphasizes the importance of using devices with up-to-date operating systems, encryption, and phishing-resistant multi-factor authentication (MFA). CISA’s Jeff Greene recommends encrypted apps for both messaging and voice communication, noting, “Encryption is your friend… it makes intercepted data unreadable.”
Fully encrypted platforms like Signal, WhatsApp, and even Facebook Messenger now provide robust security for cross-platform communication. In contrast, RCS (Rich Communication Services)—the successor to SMS—still lacks end-to-end encryption between Android and iPhone devices. While Google and Apple promise encryption for RCS, there’s no firm timeline.
Political and Industry Reactions
This breach has led to classified Senate briefings and upcoming hearings on December 11 to assess vulnerabilities in U.S. telecom networks. The situation underscores the urgent need for improved security measures.
Practical Takeaways
For now, experts recommend avoiding unencrypted texts between iPhones and Androids. Stick to encrypted platforms like Signal or WhatsApp for messaging and calls. With cyber threats becoming more sophisticated, safeguarding your communications is no longer optional—it’s essential.
Apple’s upcoming iOS 18.2 update, allowing users to change the default messaging app on iPhones, adds a timely layer of flexibility to adopt more secure options.
When it comes to protecting your digital life, timing truly is everything.
