Visitors to thousands of websites—including UK and US government sites—were forced to unknowingly mine cryptocurrency over the weekend after hackers compromised a popular browser plugin called Browsealoud, and rejigged it to hijack site visitors’ computer power.

Among the affected sites, which included the UK’s information commissioner and uscourts.gov, were some prominent Canadian URLs. According to a list of sites running the Browsealoud plugin, which offers accessibility and translation services, the websites for the Information and Privacy Commissioner of Ontario, the Ontario Trillium Foundation, and the Centre for Addiction and Mental Health (CAMH) were compromised.
