Online social networks like Twitter provide a novel channel to allow interaction between human beings. However, its success has attracted interest in attacking and exploiting through a wide range of unethical activities, such as malicious actions to manipulate users. One of the methods to carry out these abuses is the use of bots on Twitter. Such b...
Online social networks are tools that allow interaction between human beings with a large number of users. Platforms like Twitter present the problem of social bots which are controlled by automated agents potentially used for malicious activities. Thus, social bot detection is important to keep people safe from harmful effects. In this work, we ap...

A series of bots performing simulated social engineering attacks using phishing in the Twitter platform was developed to identify potentially unsafe user behavior. In this work different bot versions were developed to collect feedback data after stimuli directed to 1,287 twitter accounts for 38 consecutive days. The results were not conclusive abou...
