In this very study, we propose a new deep neural model for phishing URL identification so-called GramBeddings introducing some distinguishing novelties by (1) proposing the use of n-gram embeddings, computed on the fly, requiring no pre-training stage, (2) removing the necessity of word and sub-word level information, (3) providing a smart and efficient n-gram selection pipeline, and benefiting from attention mechanism. Other than that, we share a publicly available, large-scale and novel dataset including 800K real-world phishing and legitimate URLs. Our scheme suggests an adjustable and automated n-gram selection and filtering mechanism along with a new neural network architecture concatenating four-channel information flow through cascading CNN, LSTM, and attention layers. With that, discriminative multi-level character patterns can be discovered without any hand-crafted operation and are enabled to contribute to prediction. As a result, the proposed system provides the following features in the problem domain: (i) real-time, end-to-end and high performance inference, (ii) language-agnostic prediction, and (iii) removal of the necessity of any third-party service or hand-crafted feature. These experiments show that our approach outperforms the other models in the literature with an accuracy of 98.27%. Moreover, the comparative study conducted with several datasets clearly verifies the superiority of our model in all tests. We also examine the robustness of our model against a real-world adversarial attack and discuss the methods of overcoming such an attack. Our codebase is shared with the community to be used for benchmarking purposes in the future.
