The FBI has issued a cautionary note to smartphone users regarding the importance of encrypting text messages, particularly when communicating between Apple and Android devices. This advisory comes in the wake of a significant cyber espionage campaign allegedly orchestrated by hackers linked to the People’s Republic of China (PRC). The FBI, alongside the Cybersecurity and Infrastructure Security Agency (CISA), revealed that these hackers have been targeting telecommunications infrastructure, focusing on individuals involved in government or political activities. The breach has resulted in the theft of sensitive customer call records and information subject to U.S. law enforcement requests.
Despite ongoing investigations, cybersecurity officials have yet to neutralize the threat posed by these hackers. In light of this situation, users are encouraged to adopt secure messaging applications to safeguard their communications.
What text messages should be encrypted
Officials recommend utilizing messaging apps such as WhatsApp or Signal, as standard text messages exchanged between Apple and Android devices lack encryption. While messages sent between two Apple devices or two Android devices are secure, the vulnerability arises when messages traverse between these two platforms.
Here are two popular messaging apps that provide end-to-end encryption, ensuring your conversations remain private:
How to encrypt text messages with WhatsApp
WhatsApp is a widely used application that allows for encrypted messaging between Apple and Android users. To get started, Apple users can download the app from the App Store, while Android users can find it on Google Play. The app is free to download and use.
Upon installation, users must accept the Terms and Conditions and grant necessary permissions, such as access to contacts and notifications. Next, you will select your country and register a phone number capable of receiving calls and texts—landlines or toll-free numbers are not eligible.
WhatsApp will then prompt you to verify your number via a voice call or a text message containing a code. After verification, you’ll need to input your birth year and name before clicking “Done.” With these steps completed, you can start messaging and calling your contacts through WhatsApp, provided you have Wi-Fi or cellular data.
How to encrypt text messages with Signal
Signal serves as another robust option for encrypted messaging, ensuring your communications between Apple and Android users are secure. Similar to WhatsApp, Apple users can download Signal from the App Store, while Android users can access it via Google Play. This app is also free to download and use.
Once installed, users must accept the Terms and Conditions and enable necessary permissions. You will then enter a phone number that can send and receive calls and texts. Signal will send a verification code to this number, which you will need to input into the app to confirm your identity.
After verification, you will create a PIN for accessing your information, ensuring your data remains encrypted. You’ll also be prompted to enter your first and last name to establish your Signal profile. Once set up, you can begin messaging and calling through Signal, with the app displaying contacts who are already using the service. Like WhatsApp, Signal requires Wi-Fi or cellular data for operation.
