"Bureau of Meteorology hacked by foreign spies in massive malware attack, report shows"
Clearly someone has an interest in targeting it - who knows if HTTPS would actually mitigate the risks though. Doubt it would hurt and would not be that difficult. It shows the lack of maintaince in BOM that leads to events like this.
Just an educated guess ;)
I'm reminded of the COVID reporting fiasco we had in the UK in October [0] where Public Health England - an agency of the NHS - lost COVID data because they were using .xls files to log data rather than .xlsx - the former was silently truncating critical datasets because of a hard row limit. The .xlsx format first appeared in 2007, so the NHS have only had 13 years to get their act together.
