Submission + - Snapchat account registration CAPTCHA defeated (

hypnosec writes: Snapchat's security troubles continue as a security researcher has managed to hack its account registration CAPTCHA system with a program of less than 100 lines that took 30 minutes to develop. Steve Hickson, a computer engineer by education, wrote a small computer program with very little effort that identifies Snapchat’s ghost from the given set of images. Hickson equates Snapchat’s ghost very particular and calls it a template that can be matched easily using a computer program. Hickson used a combination of Open Source Computer Vision Library (OpenCV), SURF points and FLANN matching “with a uniqueness test to determine that multiple keypoints in the training image weren't being singularly matched in the testing image.”
