Kyivstar (one of the biggest mobile service provider in Ukraine) has changed it’s CAPTCHA. I don’t realy know why, but I hope they found our site and understood the problem. Understanding is good, but rushing is bad. Instead of think about how strong CAPTCHA should be built they just made primitive changes. It’s now in 100 times stronger then was, but still is easy to beat. Another primitive CAPTCHA was implemented at UMC (biggest competitor of KS). And it’s still there!
Well, we have added couple new CAPTCHAs on our weaklist, the most known is rapidshare.de CAPCTHA images – yes, it’s not too good.
We are glad to present you the new 1.2 version of our tEABAG_3D CAPTCHA. It’s more hard to break, it looks nicer (I hope), it’s rewritten with PHP5 and it’s OOP well-made now. I hope you’ll like it.
It is a small part of the internet that is disappearing. Google announced that CAPTCHA as we knew it today was going to be replaced by an invisible CAPTCHA. You don’t have to re-enter unreadable or incomprehensible bits of text, click on a button, or find the right animals, or find the right scales to prove you’re not a robot and get to the right page. Instead, Google will simply rely on how you navigate, explains the web giant in a blog post.
“Human users will be able to pass by without seeing the small box “I am not a robot” while suspicious users and bots will have to solve challenges.”
If you have spent a little time on the internet since the early 2010’s, you have necessarily seen these little boxes on which we sometimes spend a lot more time than expected trying to decipher.
CAPTCHA, her first version was born in the early 2000s, at Carnegie Mellon University in the United States. At the time, Mental Floss explains, the team led by Luis von Ahn “wanted to find a way to eliminate the huge armies of spambots who were posing as normal users.” Together, they designed a program that shows on the screen distorted text, that a computer is unable to be free, but that a human can easily decipher (well, normally).
“All a human had to do was type that text in a box, and they could continue their navigation.”
After some time of browsing the web we found a set of new CAPTCHAs which must take a place in a Weakness list. Some of them are small and local, but it also contain a world wide famouse systems. Due to a self-confidence of webmasters we will have a lot of places where OCR may be successfully applied.
We decided to start a series of publications with explanations of how to beat a CAPTCHA. First article is now in the stage of illustrating and preparing to be published here.
Our Team has completed OCR for Kyivstar SMS sender. It shows, that Kyivstar don’t want to spent even small money to protect customers from available SMS spam attack. They will think of you There is an opinion, that they will not change this system until SMS spam starts.
