Using NLP to Detect Hackers Malicious Attack/Hackers Forums’
Posts
, Abstract
In the research, NLP-drive Machine Learning model is proposed to detect and
predict attacks and cyber-threats by analyzing forum discussions of hackers.
Traditional keyword-based tracking system often fail to identify and capture the
hacker language contextual shifts and nuances, leading to missed threats and false
positives. By leveraging techniques of NLP such as NER (Named Entity
Recognition), sentiment analysis) and Stylometry, the approach is to automate
malicious intent detection, determine groups of hackers and predicts plans of
attacks. The effectiveness of model is evaluated via Random Forest Classifier,
accomplishing high-level of accuracy in distinguishing between general and
malicious discussions. NLP-driven system is compared to traditional methods and
superior performance is demonstrated in attribution of threat and early prediction of
attack. The research also highlighted challenges such as adversarial robustness and
multilingual analysis as well as tracking hacking forums concerns.
