Mule accounts are created to enable money laundering, scams, bribery, and other financial crimes. Some of the money mules are genuine lawbreakers, but many of them could be simply ignorant and practise atrisk behaviours in their banking activities. An online survey on at-risk behaviours in banking activities was participated by 201 respondents. The at-risk behaviours include disclosure of bank account information to others, performing cash transactions on behalf of others, giving ATM cards and Pins to others, and renting out the account to others. Twenty-nine per cent of the respondents gave their ATM Cards and Pins to others, while 21% rented out their bank accounts to others. Approximately 88% of those who rented out their bank accounts cited reward-seeking as their main reason. Inter-rater screening on the survey data further observed that 43% of the 201 respondents tended to be money mules. The Chi-Square Test of Independence recorded significant relationships between the tendency to be a mule or nonmule account holder and the demographic factors of the respondents, namely Gender, Academic Qualification, Employment Status, Area and Monthly Income. Binary Logistic Regression further confirmed that Academic Qualification, Employment Status, and Area are the three significant determinants. Hence, substantive awareness campaigns and preventive measures should be systematically targeted at individuals who have no university education, work in the private sector, and stay in a metropolitan. Nevertheless, this should be carefully observed and in need of further verification due to the limitation of the nature of the online survey.
