From the article: ""Backdoor" may not be the right term, though it's difficult to be certain without knowing the details of the system's technical architecture. In the complaint, the term is used to describe a duplicate of the PSCA's DES running on servers based in a Huawei facility in Suzhou, China. Whether that copy arises from a covert remote access capability or an overt replication option under indifferent or permissive security policy isn't clear." So zero evidence of a backdoor. > Apart from propaganda value of trying to drive wedge between PRC and Pakistan. ... Seems like a very futile suit apart from geopolitcal factors. That's exactly how it reads for me as well.
