Abstract : Phishing represents a genuine risk to the Internet economy. Email has turned out to be a necessary verbal exchange tool in contemporary lifestyles. In recent days, email remains as the foremost generally utilized medium to dispatch phishing attacks. As a result, detection of phishing emails has been considered as an important task in the field of Cybersecurity. In this working note, we use word embedding and Neural Bag-of-ngrams with deep learning methods such as convolutional neural network (CNN), recurrent neural network (RNN), long short-term memory (LSTM) and multi-layer perceptron (MLP) to detect phishing email. Both word embedding and Neural Bag-of-ngrams facilitates to extract syntactic and semantic similarity of emails. Deep learning algorithms facilitate to extract the abstract and optimal feature representation and fully connected layer with non-linear activation function for classifcation. All the experiments are done on anti-phishing shared task corpus at IWSPA-AP 20181. All the models performed well during training phase. Moreover, word embedding with LSTM obtains 10-fold cross validation accuracy of 0.991 on sub task 12 and 0.971 on sub task 23. Based on the experimental results, we claim that word embedding with deep learning, specifcally LSTM is appropriate for the anti-phishing task. Copyright © by the paper's authors.
