Why Websites Get Hacked

I spend a good amount of time engaging with website owners across a broad spectrum of businesses. Interestingly enough, unless I’m talking large enterprise, there is a common question that often comes up: Why would anyone ever hack my website? Depending on who you are, the answer to this can vary. Nonetheless, it often revolves around a few very finite exp

The Dynamics of Passwords

How often do you think about the passwords you’re using? Not only for your website, but also for everything else you do on the internet on a daily basis? Are you re-using any of the same passwords to make it easier to remember them? We see it all too often: weak passwords used for FTP, database configuration, cPanel, and CMS logins.

Creative Evasion Technique Against Website Firewalls

During one of our recent in-house Capture The Flag (CTF) events, I was playing with the idea of what could be done with Non-Breaking Spaces.

Malvertising on a Website Without Ads

When you first configure your website, whether it be WordPress, Joomla, Drupal, or any other flavor of the month, it is often in its purest state. Unless ofcourse the server was previously compromised, which in it of itself is another conversation outright. Barring that one instance, the new website should not exhibit any malicious behavior. Or so you would

IIS, Compromised GoDaddy Servers, and Cyber Monday Spam

While doing an analysis of one black-hat SEO doorway on a hacked site, I noticed that it linked to many similar doorways on other websites, and all those websites were on IIS servers. When I see these patterns, I try to dig deeper and figure out what else those websites have in common. This time I revealed quite a few GoDaddy Windows servers have been pwned
