2017 Proceedings of the 26th International Conference on World Wide Web Companion - WWW '17 Companion  
In this paper, we perform temporal pattern mining on bot activities in Twitter.  ...  We discover motifs (repeating behavior), discords (anomalous behavior), joins, bursts and dynamic clusters in activities of Twitter bots, and explain the significance of these temporal patterns in gaining  ...  TEMPORAL PATTERNS We apply five temporal pattern mining algorithms on the bot activity series and describe several successful cases in this section.  ...

A graph-theoretic framework for isolating botnets in a network

Padmini Jaikumar, Avinash C. Kak
2012 Security and Communication Networks  
As practically all aspects of how a botnet manifests itself in a network-such as the online bot population, bot lifetimes, and the duration and the choice of malicious activities ordered by the bot master-can  ...  Our approach depends primarily on the temporal co-occurrences of malicious activities across the computers in a network and is independent of botnet architectures and the means used for their command and  ...  The communication patterns associated with bots reflect their ability to engage in coordinated malicious activities.  ...

RTbust: Exploiting Temporal Patterns for Botnet Detection on Twitter [article]

Michele Mazza, Stefano Cresci, Marco Avvenuti, Walter Quattrociocchi, Maurizio Tesconi
2019 arXiv   pre-print
In this way, we uncover a 'normal' retweeting pattern that is peculiar of human-operated accounts, and 3 suspicious patterns related to bot activities.  ...  We design a novel visualization that we leverage to highlight benign and malicious patterns of retweeting activity.  ...  Then, it compares the temporal patterns of retweeting activity of large groups of users.  ...

Down the bot hole: actionable insights from a 1-year analysis of bots activity on Twitter [article]

Luca Luceri, Felipe Cardoso, Silvia Giordano
2020 arXiv   pre-print
In this paper, we present a long term (one year) analysis of bots activity on Twitter in the run-up to the 2018 U.S. Midterm Elections.  ...  Uncovering the strategies behind bots' activities is of paramount importance to detect and curb such campaigns.  ...  Interestingly, also in the disentangled sharing activities, bots followed a similar temporal pattern of human users over the whole year.  ...

Collective Behavior of Social Bots Is Encoded in Their Temporal Twitter Activity

Andrej Duh, Marjan Slak Rupnik, Dean Korošak
2018 Big Data  
Here we show that there are significant differences in collective behaviour between population of bots and population of humans as detected from their Twitter activity.  ...  Collective behaviour of populations of social bots has not been yet widely studied, though understanding of collective patterns arising from interactions between bots would aid social bot detection.  ...  In There are no obvious patterns visible in these spike trains. We can find highly active users as well as completely silent ones in these samples.  ...
