Nigerian Computer-Mediated Fraudulent Text Messages

This dataset comprises Nigerian digital fraudulent text messages collected between January 2022 and September 2024 through purposive sampling. The messages were sourced from the personal inboxes of researchers, colleagues, and students. The content primarily includes phishing and scam messages impersonating credible institutions (e.g., CBN, commercial banks), using themes such as BVN system upgrades, ATM card deactivation, incomplete bank registration, and cashless policy enforcement. Some messages also promote fraudulent investment schemes, crypto scams, and Ponzi schemes.

本数据集涵盖2022年1月至2024年9月期间，通过目的抽样（purposive sampling）采集的尼日利亚电信欺诈短信。这些短信采集自研究人员、同事及学生的个人收件箱。其内容主要为冒充可信机构（如CBN、商业银行）的钓鱼式诈骗（phishing）与欺诈短信，涉及主题包括银行验证号码（Bank Verification Number）系统升级、ATM卡停用、银行注册未完成以及无现金政策执行等。部分短信还会推广虚假投资计划、加密货币诈骗及庞氏骗局。
