Fooling Samsung Galaxy S8 Iris Recognition

Posted on by

We have a love-hate relationship with biometric ID. After all, it looks so cool when the hero in a sci-fi movie enters the restricted-access area after having his hand and iris scanned. But that’s about the best you can say about biometric security. It’s conceptually flawed in a bunch of ways, and nearly every implementation we’ve seen gets broken sooner or later.

Case in point: prolific anti-biometry hacker [starbug] and a group of friends at the Berlin CCC are able to authenticate to the “Samsung Pay” payment system through the iris scanner. The video, embedded below, shows you how: take …read more

I just received a phishing text message, how could this have worked?

Posted on by

I received a phishing text message that pretended to be my bank. It had a link that went to a site that redirect to the following script:

<html><script language="javascript">var page = "Login.php?sslchannel=true&sessionid=XXX”; top.location = page; </script></html>

When I did a wget on that page with the rest of the full url it ran the following script:

<script>
    window.googleJavaScriptRedirect = 1
</script>
<script>
    var n = {
        navigateTo: function(b, a, d) {
            if (b != a && b.google) {
                if (b.google.r) {
                    b.google.r = 0;
                    b.location.href = d;
                    a.location.replace("about:blank");
                }
            } else {
                a.location.replace(d);
            }
        }
    };
    n.navigateTo(window.parent, window, "https://www.banksite.com/");
</script><noscript><META http-equiv="refresh" content="0;URL='https://www.banksite.com/'"></noscript>

From a technical perspective, I’m trying to figure out what this phishing text could have done in the worst case scenario.

Which attributes of a WPA AP certificate are used by a client device in deciding if the certificate has been trusted before?

Posted on by

When connecting to a new AP, the client device will pop a warning to ask if the certificate of the new AP should be trusted. If trusted, the warning doesn’t show anymore if the certificate is known to have been trusted before… Continue reading Which attributes of a WPA AP certificate are used by a client device in deciding if the certificate has been trusted before?→
