Twitter botnets and spam attacks

Dr Shi Zhou’s team discovered two massive botnets on Twitter, namely the Star Wars Botnet with >360,000 bots and the Bursty Botnet with >500,000 bots, which are orders of magnitude larger than previous works. They also uncovered a large-scale spamming attack by the Bursty bots and reconstructed the full process of the attack. They also proposed a framework to assess the effectiveness of future bot detectors.
