FBI Warns iPhone and Android Users: Avoid Sending Sensitive Text Messages
- Using devices that receive automatic operating system updates.
- Employing responsibly managed encryption.
- Enabling phishing-resistant multi-factor authentication (MFA) for email, social media, and collaboration accounts.
The FBI has issued a critical warning to smartphone users, urging them to exercise caution when sending text messages. This alert highlights the risks associated with sharing sensitive information—such as personal data, financial details, or authentication codes—via SMS or messaging apps. Cybercriminals increasingly exploit weaknesses in text communication, using tactics like phishing, SIM-swapping, and social engineering to steal information or gain unauthorized access to accounts.
The agency advises users to avoid sharing private information through texts and to use secure, encrypted communication platforms whenever possible. Additionally, they recommend enabling two-factor authentication (2FA) through authentication apps instead of SMS to prevent interception. The warning underscores the importance of staying vigilant in a world where digital communication has become a prime target for hackers.
The message is clear: Think before you text. Protect your privacy and reduce the risk of falling victim to scams by adopting safer communication practices.
Updated on December 5: FBI Highlights Rising Concerns Over Chinese Cyberattacks and Urges Secure Communication
The FBI has expanded its commentary, alongside reports of increasing U.S. political pressure, emphasizing the extensive scale of ongoing Chinese cyberattacks on U.S. networks.
The timing is notable. Just as Apple’s adoption of RCS (Rich Communication Services) seemed poised to reinvigorate text messaging as an alternative to WhatsApp’s dominance, a significant obstacle has emerged. While messaging between Android devices or between iPhones is secure, cross-platform communication between the two lacks the same protections.
Now, both the FBI and CISA (Cybersecurity and Infrastructure Security Agency) are advising Americans to prioritize the use of responsibly encrypted messaging apps and phone calls. This recommendation comes against the backdrop of cyberattacks that are reportedly "ongoing and potentially far more extensive than previously believed."
Fully encrypted communication platforms remain the strongest defense against such compromises. Authorities are urging Americans to adopt these tools wherever possible to safeguard their personal and professional data.
Cyberattacks by ‘Salt Typhoon’ Highlight Vulnerabilities in U.S. Communication Networks
Cyberattacks linked to Salt Typhoon, a group associated with China’s Ministry of Public Security, have raised alarm over the security gaps in critical U.S. communication infrastructure. However, experts note that the risks aren’t new. Without fully end-to-end encrypted messaging and calls, communication content has always been vulnerable to interception—a reality emphasized by Apple, Google, and Meta, who advocate for encryption as even they cannot access protected content.
A senior FBI official shed light on the severity of the threat, explaining that the investigation into cyber espionage targeting U.S. commercial telecom networks is ongoing and evolving. “The facts will evolve over time,” the official stated, emphasizing the campaign’s scale. The FBI uncovered that Chinese-affiliated cyber actors had infiltrated multiple telecom companies, compromising networks to enable extensive espionage activities. The investigation began in late spring and early summer of this year, revealing the breadth of this cyber threat.
To mitigate risks, the FBI urges citizens to adopt secure practices, including:
