Kaspersky reveals CAPTCHA-tricking Podec Trojan
Kaspersky Labs has revealed details of what it claims is the first malware to successfully outwit the CAPTCHA online image-based verification system.
The Russian internet security software company said on March 10 that the malware, Trojan-SMS.Android.Podec, was first detected by its security analysts in late 2014, but has since been updated.
The Podec malware automatically forwards CAPTCHA requests to a real-time online human translation service, Antigate.com, which converts the image to text, and relays that data back to the malware code within seconds, convincing the verification system that it is a person. The purpose of the Trojan is to extort money from victims by subscribing thousands of infected Android users to premium-rate services, said the security software company.
