Thousands of sites were injected with a in-browser Monero miner today after a popular accessibility script was compromised. With 4,275 sites affected, this included government websites such as uscourts.gov, ico.org.uk, & manchester.gov.uk. Infosec consultant Scott Helme was able to quickly track the script to 4,000 sites that were affected in the incident. Helme found the script contained obfuscated code that was injecting the Coinhive miner into all of these websites.
