''dutch sites abused by blind software for 'delving' cryptocurrency''

More than a hundred Dutch websites have recently been abused to extract the crypto coin Monero. This includes sites from libraries and municipalities.


Slow computer

Lexima, the Dutch supplier of software, confirms that malicious parties have abused Browsealoud for up to four hours. Browsealoud is software that reads a webpage for the blind, visually impaired, people with dyslexia and non-native speakers.


The maker of Browsealoud, Texthelp, says that the software was infected by adding a malicious code to the software that aimed to abuse the computing power of browsers that are currently visiting sites to extract the digital currency. As a result, computers can become slower. As soon as a user closed the tab with the website in question, the digging stopped automatically.


Also sites in US and GB

Lexima supplies the software in the Netherlands to various parties. For example, 34 libraries, 23 municipalities, various healthcare organizations and TU Delft made use of the software. It is unclear whether the software is still active at all these parties.
