today in "why boot chain security really is a thing even though some enthusiasts kinda hate it": https://arstechnica.com/security/2023/09/china-state-hackers-are-camping-out-in-cisco-routers-us-and-japan-warn/

note the quote: "Cisco also said that the hacker’s ability to install malicious firmware exists only for older company products. Newer ones are equipped with secure boot capabilities that prevent them from running unauthorized firmware, the company said." 

 @55e2b80e fun fact: I switched from popOS to Fedora because it was one of only two options that had secure boot. That was it lol Been on Fedora ever since.
