Scott Helme, security consultant and the Register have recently discovered that hackers managed to damage over 4,200 sites, with many including government websites around the world, with Coinhive’s notorious Monero miner.
This included amongst others, the UK’s National Health Service, the US court info system and Australian legislatures.
Moreover, the mining took place for a couple of hours on Sunday the 11th of February before Texthelp then disabled the accessibility plugin in order to investigate the matter at hand.
The UK’s Information Commissioner’s Office and other government sites also took pages down in response to the intruders.
Due to the nature of these injections, your system wasn’t facing a security risk but you would have noticed your system stalling while searching for government information.
