The US government is considering punishing American scientists who worked with Chinese researchers *years ago, retroactively*.
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

Researchers speak out against proposal that would bar funding for U.S. scientists working with Chinese partners or training Chinese students

Russia is blocking mobile phones being brought back into the country from abroad for 24 hours, in an attempt to mitigate drone attacks. Seems like this can probably be bypassed using relay "worm hole" attacks, though it adds some complexity.

The West has a blindspot when it comes to alternative CPU designs.



We’re so entrenched in the usual x86, ARM, RISC-V world, that most people have no idea what’s happening over in China.



LoongArch is a fully independent ISA that’s sorta MIPS…sorta RISC-V…and sorta x87!

Also in Poland. It was used by Russia in 2023 to stop about 20 trains.

Yikes. Turns out you can send a plaintext radio signal to cause any train in the USA to do an emergency break. The original 'security' was just a checksum, no encryption or authentication. Reporting this took them 12 years (!) because the vendor dismissed it initially www.cisa.gov/news-events/...

New version of the IEEE 802.11 standard that underpins Wi-Fi was has been released. A total of 5969 pages!

The number of pages clearly keeps increasing. That includes more features to defend networks, but also more features to potentially abuse 👀
