Securing a directory with 777 or 775 permissions

Posted by Stanislav Furman on July 6, 2014

If in your project you have a publicly accessible directory that has full permissions (777), then it may cause serious security issues. An attacker may put an executable script or binary on your host and then run it remotely. This is a major security whole and it may lead to major problems if someone decides to attack your website.

However, sometimes on some shared webhosting servers you need have a folder that has risky 777 permissions (or, if possible, 775 which is a little bit better). As an example you can consider a folder where website users can upload their photos or images. In this case it opens a security whole for potential attackers. But, there are a few techniques that can help you to keep your website safe.

Posted by Stanislav Furman on June 16, 2014

We all use mobile devices every day. Well, at least most of us. All those smartphones, tablets, gadget-watches, etc. Most of us cannot imagine life without these things.

Regular expressions? What's that? Part 2.

Posted by Stanislav Furman on June 2, 2014

Thanks to nightbloos I can continue posting funny code samples that developers meet/write from time to time. :)

Here is another good example of how NOT to do! Please, do not try this at home! This stunt was performed by untrained professionals.  :)


<?php
$forReplace = array(",","."," ","-", "+", "#""/");
foreach($forReplace as $repl){
	$find = str_replace($repl,'',$find)
}

Obviously, in this case a regular expression function must have been used.

If you have another good examples of a funny code samples, please leave it in the comments. ;)
