The FBI has issued an urgent warning to iPhone and Android users regarding the vulnerabilities of their text messages amidst a massive cyber espionage campaign attributed to Chinese hackers, known as Salt Typhoon. Officials recommend that users cease texting between different platforms as these messages could be intercepted. In light of a significant breach involving U.S. telecommunications networks, which affected multiple providers and involved the hacking of sensitive communications, the FBI urges everyone to adopt encrypted messaging apps to enhance security. This advisory comes as a response to allegations that Chinese hackers gained access to metadata from American cell phone users, posing substantial risks to national security. U.S. government officials are stressing the importance of adopting advanced encryption methods to safeguard communications against foreign espionage.
