The Federal Bureau of Investigation recently warned Apple and Android users to stop texting each other using the RCS protocol because of a massive telecommunication breach by hacking group Salt Typhoon. According to the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI, Salt Typhoon was responsible for compromising major carriers, including AT&T and Verizon, in what is being considered one of the largest infrastructure attacks in US history. Following the breach, which mostly affected high-value government officials, CISA and the FBI have issued a wide public interest advisory for US citizens to use chat apps that offer end-to-end encryption.
