Generative Models for Spear Phishing Posts on Social Media [article]

John Seymour, Philip Tully
2018 arXiv   pre-print
We present a long short-term memory (LSTM) neural network that learns to socially engineer specific users into clicking on deceptive URLs.  ...  We augment the model with clustering to triage high value targets based on their level of social engagement, and measure success of the LSTM's phishing expedition using click-rates of IP-tracked links.  ...  We ensure our dummy account doesn't follow any other users, and so our posts are only visible to us and to our targets. The content of the post is generated by a long short-term memory (LSTM) model.  ...
