Wordpress LScache Plugin: Lockout in plugin directories
Last Updated on: Wed, 15 Apr 2026 00:00:02 Good afternoon, I received several notifications of attempted intrusions and the report indicates directories of the LiteSpeed ??plugin. There were more than 100 attempts on one site alone. I remove the plugin and a few minutes it appears installed again, without any intervention from me. The page I need help with: https://www.cft.org.br Hi, Could you please provide more information ? Best regards, Hello, thanks for the feedback. Several requests are being made for files in the /wp-content/litespeed/cssjs/daa5d.js changing only the .js file name. There have been over 3000 requests today. I believe that some script is working on the site via the LiteSpeed ??plugin. A copy of the W3 Total Cache plugin files is made in the root folder of my hosting, I believe to confuse it because it is cache routines. I have never installed the W3 Total Cache plugin, only LiteSpeed. I am available to provide any information that may help. One more piece of information, when I disable and remove the plugin it appears installed and active again on my website after some time. Hi, That file is generated by JS optimization feature , and each time you purge cache , it will be re-generated , and changing name. hmmmmm, you mean you didnt install W3TC , but it appear up in your site ? perhaps you should check with your provider if they installed it for you ? Best regards, Hello, Ive checked with the provider, it wasnt them. Why are the attacks concentrated on these files? Today, more than 300 attempts have been classified as lockout . Thank you! Hi, I am not sure what do you mean by lockout ? like request denied ? is there any completed log ? maybe you are under (D)DoS attack , if that file not exist, it will hit WP 404 page, in which , it consumes resources to process 404 page. Best regards, Hello, I believe thats it. I just wanted to inform you that the plugin is being targeted by this type of attack, perhaps a vulnerability? Thank you for your attention! Hi, Thank you for your info , I will pass this to our dev Best regards,
