The method used is Participatory Technology Development (PTD), which includes theoretical socialization, technical account security workshops, and phishing attack simulations. The program's success was measured through quantitative analysis of pre-test and post-test scores as well as observation of technical behavioral changes. The results showed a significant increase in literacy, with the participants' average score increasing from 52.1 to 85.3 (63% effectiveness).
