We talk about chip restrictions today, but the United States’ main target as it ramped up its geopolitical fight with China was Huawei.

Enormous. Outragerous are some of the words I would use. Take you time to read and learn because they are not the only culprits on the planet with such bad data protection practices
Excerpt
>>
Quite quickly I realised something was wrong. The responses I got from the network were extremely detailed and long, and were unlike anything I had seen before on other networks. The messages contained information such as the IMS/SIP server used by O2 (Mavenir UAG) along with version numbers, occasional error messages raised by the C++ services processing the call information when something went wrong, and other debugging information. However, most notable were a set of five headers near the bottom of the message:
SIP Msg

P-Mav-Extension-IMSI: 23410123456789
P-Mav-Extension-IMSI: 23410987654321
P-Mav-Extension-IMEI: 350266809828927
P-Mav-Extension-IMEI: 350266806365261

Cellular-Network-Info: 3GPP-E-UTRAN-FDD;utran-cell-id-3gpp=2341010037A60773;cell-info-age=26371
Synthesised excerpt of IMS signalling message for demonstration; not a genuine IMEI/IMSI/cell ID.
Two sets of IMSIs, two sets of IMEIs, and a Cell ID header. How curious…
Sure enough, when comparing both the IMSIs and IMEIs in the message to those of my own devices, I had been given both the IMSI and IMEI of my phone which initiated the call, but also the call recipient's.

Last month Meta announced plans for Project Waterworth, the 50,000-kilometer submarine cable that would link five continents and improve connectivity and technological development. But submarine cables can do more than enhance telecommunications. They can also keep us safe from threats like climate change and natural disasters. There are, however, some significant concerns, Cynthia Mehboob underscores for The Conversation. Plus, what year was the first undersea cable laid? It’s probably earlier than you think:
