Show Notes:

Malware hosted in your browser

  • Last show, we talked about malware, blocking it via URLs, and malware which spoofs the domain names, thereby bypassing many URL-based filters.
  • This show, we have an instance of malware which completely defeats all of the above, in a very simple and clever way.
  • A common way to steal credentials is hosting a webpage which looks a lot like the real thing. Google, Facebook, Paypal, etc are all targets of this. It is simple to do. Just throw up a web page, and start directing people to it.
  • Lots of ways to defeat this with conventional tools
  • This method bypasses all those tools
  • Tom Scott tweeted about malware he received via email.
  • when you click on the link, you get what appears to be a Google Login page.
  • The URI is of the form: data:text/html,https…… lots of spaces <script src=date:text/html;…. etc
  • However, it is hosted entirely within your browser
  • Matt Hughes reportrd that Andriod actually tries to autofill his Google account credentials on that data URI
  • This has been around at least a year, and was written about by linkcabin
    spoofs the login page by hosting it in your browser.
  • Suprisingly common and is often using to phish Google or Paypal
