WordPress Malware: WP-VCD

WordPress Malware: WP-VCD

Using nulled WordPress themes and plugins is bad. Why? Because sometimes (well, most of the time) nulled plugins or themes contain malicious code that looks something like this: That’s wp-vcd.php. When a WordPress website is infected with this piece of malware, the infected file resides in the “wp-includes” directory and every time a page on a WordPress website is accessed overwrites the functions.php file with malicious code that looks like this: Removing the code doesn’t do any good – as…

Filtering user input in web applications: the basics

Filtering user input in web applications: the basics

SQL Injection. Cross-Site Scripting. These are just two of web application security flaws that can be prevented by effectively filtering user input.

Public speaking can be enormously empowering and fulfilling. I have spoken at quite a few international conferences – I always reflect on what I’ve done right and what’s been done wrong after the conference, but not once have I covered how exactly do I prepare for them. I do not overload the slides with content Overloading slides with content is one of the top no-nos when doing any form of presentation. The audience either listens to the speaker or reads…

CSRF Tokens? What Tokens?

CSRF Tokens? What Tokens?

In a previous blog post where I covered Cross-Site Request Forgery and what potential impacts and consequences such an attack may have, I wrote that a popular way to prevent such an attack from unfolding is to generate tokens. In that blog post, I noted that when a website generates tokens, a CSRF attack might be stopped. One thing I did not cover though is that whether the attack will be stopped or not depends on how the tokens are implemented. Confused?…
