The aim is to identify frameworks that integrate OSINT with Machine Learning/Deep Learning/Artificial Intelligence to achieve better results. This question also considers the comparison of model results with and without OSINT.

Research Process

To conduct the research, various keywords related to OSINT, OSINT tools and techniques, cybercrime and organised crime detection using OSINT, counter cyber criminals using OSINT, threat intelligence using OSINT, application of OSINT in cyber defence, security intelligence, disaster management, social opinion extraction, sentiment analysis, malware analysis, vulnerability assessment, national security surveillance, and counter misinformation were used. These keywords were searched in electronic databases such as Google Scholar, ACM Digital Libraries, Web of Sciences, Science Direct, and IEEE Xplore. Additionally, various tools and techniques of OSINT, magazines, blogs, and newsletters related to OSINT were also searched. The selection of works was based on their relevance to OSINT, applications of OSINT, possible domains for integration with OSINT, citation score, reputed journals/publications, and real-life-based scenarios. The analysis of the resources accessed and used for the study of OSINT trends in cybersecurity using various AI/ML/DL techniques.

Extracting Social Opinion and Emotions

Aye and Aung (2020) proposed a model for determining user opinions in Myanmar language using text analysis techniques. Kandias et al. (2017) conducted an experiment on Facebook users to determine the level of stress. Yadu and Shukla (2020) analysed emotions contained in tweets from Indian Air Asia Service using five different classification techniques. Prabhakar et al. (2019) used AdaBoost (Ensemble) and other classifiers to build a robust sentiment analysis model with a precision of 84.5%. Wadawadagi and Pagi (2020) explored the use of deep neural networks in sentiment analysis.

Naseem et al. (2019) proposed a model based on Bidirectional short-term memory (BiLSTM) and hybrid word representation for sentiment analysis in airline tweets. Soomro et al. (2020) analysed more than 18 million tweets related to the novel coronavirus to study the relationship between the number of infections and public mood. Garcia and Berton (2021) conducted sentiment analysis in Portuguese using Twitter data to analyse the consequences of the pandemic in the United States and Brazil.

Mishra et al. (2019) analysed sentiments of various reviews and created a hotel recommendation system. Jain and Dandannavar (2016) studied sentiment analysis using Twitter data and used classifiers such as decision tree (DT), support vector machine (SVM), and naive bayes (NB) for training. Shuai et al. (2018) used Chinese hotel reviews and Doc2Vec to analyse sentiment and found that SVM gave the best result. Hashida et al. (2018) proposed a model based on distributed multichannel representation for interpreting text data.

Cyber Crime and Organised Crime

Digital forensics and open-source intelligence are the two broad types of cyber crime investigations. Cyber crime is divided into categories such as crime against confidentiality, integrity, and availability (CIA), content crime, computer crime, and other types of cyber crime. Nazah et al. (2020) highlighted the eight primary cyber crimes, including human trafficking, pornography, child pornography, assassination, drug sales, terrorist activity, cybercrime markets, and cryptocurrency exchange. The choice of tools and techniques in cyber investigations has a significant impact on the outcome. Quick and Choo (2018) applied OSINT in digital forensics to improve the analysis of criminal intelligence. Delavallade et al. (2017) proposed a model based on social network data to extract crime indicators and predict future crimes.

Shestak and Koscheeva (2021) discussed the increase in cybercrime rates during the coronavirus pandemic and mitigation procedures. Valluripally et al.

(2020) developed a device for real-time tracking of crime hub locations across Indian states. Edwards et al. (2015) described data mining methods such as natural language processing, information extraction, social network analysis, computer vision, and machine learning for gathering intelligence on criminal or terrorist groups. Liao et al. (2016) proposed iACE, a technology for automatically gathering intelligence from multiple sources and analysing data relationships.

Phishing is a social engineering attack, and detecting and mitigating phishing attacks is crucial. Alabdan (2020), Rastenis et al. (2020), Wang et al. (2020), and Churi et al.
