REUTERS: Thousands of websites, including ones run by U.S. and UK government agencies, were infected for several hours on Sunday (Feb 11) with code that causes web browsers to secretly mine digital currencies, technlogy news site The Register reported.
More than 4,200 sites were infected with a malicious version of a widely used tool known as Browsealoud from British software maker Texthelp, which reads out webpages for people with vision problems, acording to The Register.
The tainted version of Browsealoud caused inserted software for mining the digital currency Monero to run on computers that visited infected sites, generating money for the hackers behind the attack, The Register said.
The news comes amid a surge in cyber attacks using software that forces infected computers to mine cryptocurencies on behalf of hackers. The prevalence of these schemes has increased in recent months as the volume of trading in bitcoin and other crypto currencies has surged.
