The popularity of blogging software, with all its vulnerabilities, has spawned thousands of malicious cross-site scripting attacks. With each technological advance, new targets are created for the unscrupulous hacker.

Who Has Been Targeted With Cross-Site Scripting?

Hackers have not neglected immense commercial sites. Facebook, PayPal, Hotmail, Gmail and Twitter have all had issues with cross-site scripting. Often referred to as XSS, cross-site scripting is a major threat to blogs. Owners of blogs should be aware of the dangers, and what actions must be taken to prevent a cross-site scripting attack on their site.

Blog Vulnerabilities and XSS

Most cross-site scripting vulnerabilities take place on server-side code, while DOM (document object model) is a method used by hackers to exploit vulnerabilities on client-side code. Running antivirus or spyware blockers provide some protection, but not nearly enough to prevent attacks from outside.

Possible Results of Cross-Site Scripting Attacks

These are just a few of the many consequences of a cross-site scripting attack:

  • Website downtime
  • Theft of user accounts
  • Theft of credit card numbers and passwords
  • Theft of session cookies
  • Theft of users’ files
  • Manipulation of files
  • Loss of confidence in the business
  • Creation of fake log-in pages
  • Fake posts redirecting to malicious pages
  • Installation of malware in users’ computers

It only takes a single XSS vulnerability to create havoc for a business. Since it is estimated that over 80% of websites have one or more cross-site scripting vulnerabilities, hackers are never unemployed.
