"Pulitzer-winning website Politifact hacked to mine crypto-coins in browsers Mysterious malicious code silently chews up CPU cycles to craft cash on visitors' dime Politifact, the Pulitzer Prize-winning website devoted to checking the factual accuracy of US politicians' words, appears to have been hacked so that it secretly mines cryptocurrency in visitors' browsers. ...It fires up code from Coin Hive in browsers to generate Monero coins, each worth about $95, for the miscreants who embedded the software in the site's pages..." https://www.theregister.co.uk/2017/10/13/politifact_mining_cryptocurrency/
I submitted the .js script mentioned in the article to VT and zip detections on it. Looked at the script, redirects to here htxp://bit.ly/2sD82FG . Suspect that is the bugger setting up the coin miner.
