Yes, many. The NSA embedded a cryptographic trapdoor in the Dual_EC_DRBG random number generator and pushed it into Juniper Networks' VPN firmware; in 2012, Chinese intelligence swapped the secret constants and turned the same backdoor against its creators. In 2004, unknown actors exploited the lawful intercept capabilities built into Ericsson switches at Vodafone Greece to wiretap the Prime Minister and dozens of senior officials during the Athens Olympics. In 2024, China's Salt Typhoon group compromised the CALEA wiretap infrastructure that US law has mandated in every American telecom since 1994, intercepting calls between presidential candidates and accessing metadata on over a million users through the exact systems AT&T and Verizon built for the FBI.
