Thousands of websites worldwide hijacked by a cryptocurrency mining code due to the hack of the popular Browsealoud plugin. Hackers injected an obfuscated version of the mining code in the plugin that once converted from hexadecimal back to ASCII allowed to load the mining software in the webpage. The list of compromised websites includes the UKs NHS, The City University of New York (cuny.edu), and the US government’s court system. Once discovered the hack some sites web down, the ICO also took its website down.”]
