A quick reminder for folk who aren't sure whether they need to secure their home or small-office devices:
https://www.ukauthority.com/articles/major-shift-in-chinese-cyber-attack-activity
The UK’s National Cyber Security Centre (NCSC) and international partners have issued a joint advisory warning of a widespread shift in tactics by China-nexus cyber actors, who are increasingly using large-scale networks of compromised devices to route malicious activity
“Botnet operations represent a significant threat to the UK by exploiting vulnerabilities in everyday internet-connected devices with the potential to carry out large-scale cyber attacks,” said Paul Chichester, NCSC Director of Operations.
Of course, this isn't just a UK issue. China (along with Russia, North Korea and Iran mostly) have been waging a cyber war on other nations for years. In the last couple of years, the war has heated up massively.
So this is a reminder not to be part of the problem.

Have fun but keep others safe as well as yourself.
