The post discusses the vulnerabilities in telecom tech stacks, particularly highlighted by recent 'Salt Typhoon' cyber attacks. Users express skepticism about the claims made regarding the inherent insecurity of telecom systems, pointing to misinterpretations of the evidence, such as the focus on Freeswitch. Concerns are raised about how these insecurities could be exploited not only by state-sponsored actors and organized crime but also the implications for fraud within payment systems. The idea of rewriting telecom software in more secure languages like Rust is suggested as a long-term solution to mitigate such vulnerabilities.
