Additional information
<19>This paper investigates the security of latest text CAPTCHAs, as deployed by major companies such as Yahoo!, Tencent, Sina, China Mobile and Baidu, each with hundreds of millions of users. We proposed a novel and generic attack, which successfully breaks a whole family of hollow CAPTCHAs. This suggests that the underlying security mechanism is broken. We also discussed lessons and guidelines for designing better hollow CAPTCHAs. ACM SIGSAC conference on Computer & Communications Security is a premier event (in 2013, 530 submissions and 20% acceptance rate).
