Abstract

This paper tests disruption strategies in Twitter networks contain-ing malicious URLs used in drive-by download attacks. Cybercriminals usepopular events that attract a large number of Twitter users to infect andpropagate malware by using trending hashtags and creating misleading tweetsto lure users to malicious webpages. Due to Twitter’s 280 character restric-tion and automatic shortening of URLs, it is particularly susceptible to thepropagation of malware involved in drive-by download attacks. Consideringthe number of online users and the network formed by retweeting a tweet, acybercriminal can infect millions of users in a short period. Policymakers andresearchers have struggled to develop an efficient network disruption strategyto stop malware propagation effectively. We define an efficient strategy as onethat considers network topology and dependency on network resilience, whereresilience is the ability of the network to continue to disseminate informationeven when users are removed from it. One of the challenges faced while curbingmalware propagation on online social platforms is understanding the cyber-criminal network spreading the malware. Combining computational modellingand social network analysis we identify the most effective strategy for dis-rupting networks of malicious URLs. Our results emphasise the importanceof specific network disruption parameters such as network and emotion fea-tures, which have proven to be more effective in disrupting malicious networkscompared to random strategies. In conclusion, disruption strategies force cy-bercriminal networks to become more vulnerable by strategically removing malicious users, which causes successful network disruption to become a long-term effort.
