Cybercriminals have found in social networks (e.g., Twitter and Facebook) a propitious medium to launch massive cyber-attacks. Using compromised or fake accounts, criminals can exploit the inherent trust between connected users to effectively spread malicious content and perform scams against users. Detecting those malicious accounts, also known as spammer detection, on social networks has received increasing attention from government, industry, and academia. One of the long-standing unsolved challenges for spammer detection on social networks is lack of universal objective standard on feature extraction for spammer detection. Researchers often handcraft features in a subjective manner based on individual experience, which is time-consuming and inevitably induces bias to the feature extraction process. This talk introduces a new framework that provides an innovate but also practical solution to accurate and efficient spammer detection on social networks like Twitter. This framework adopts deep learning techniques that are mostly used in the area of image recognition, and develops new spammer detectors which can automatically learn universal and discriminative features to identify spammers with high accuracy.
