Google recently took down nine applications from the Google Play Store after security researchers at Dr Web (first reported by ArsTechnica) found these malicious apps using a special mechanism to trick users into handing over their Facebook credentials.
The apps reportedly lured users into disabling in-app advertisements by linking their Facebook profile to the app. However, while an actual form popped up where users could enter their Facebook details, malicious JavaScript code would capture the usernames and passwords.
“This script was directly used to highjack the entered login credentials. After that, this JavaScript, using the methods provided through the JavascriptInterface annotation, passed stolen login and password to the trojan applications, which then transferred the data to the attackers’ C&C server. After the victim logged into their account, the trojans also stole cookies from the current authorization session. Those cookies were also sent to cybercriminals,” said the researchers at Dr Web.
