Huawei is a massive Chinese telecommunications company currently dominating the development of 5G wireless infrastructure. To the same degree to which the Internet is surveilled by the NSA, the 5G network will be surveilled by the Chinese Communist Party and will be a vector for cyberattacks. The existing software is laden with backdoor access, zero day vulnerabilities, as if intentionally engineered to enable such attacks.
The arrest of Huawei Chief Financial Officer, Meng Wanzhou in Canada last December is apparently unrelated to these concerns, having to do with Huawei’s sale of equipment to US-sanctioned countries, including Iran and North Korea. She is awaiting extradition to the US.
