With the advancement of technology, one of the major concerns of governments is cyberspace security (
1). Today, people perform many daily tasks using cyberspace. This new technology, despite its advantages, has created new forms of criminal and abnormal behaviors that are known as cybercrime. Cybercrime includes any illegal use of a computer or a network (
1). These offenses could menace national safety and economic security. The emotional and financial damages caused by cybercrimes are considerable and different (
2) than other crimes. Despite the growing threat of cybercrime, there is little information about its psychological causes.
Cybercrime is different from traditional crime. It is unstable in time and space and has broken geographic boundaries and changed the classic definition of crime (
2). Few studies have been conducted to investigate the causes and the profile of cybercrime (
2), though various theories have been considered this criminal behavior, its reasons and risk factors. One of them is Bowlby’s attachment theory (
3). Attachment is defined as a profound and stable emotional connection that relates individuals to one another in time and place (
3,
4). This bond includes special actions in children, such as a desire to join an attachment schema in unhappy or unsafe situations (
4). This deep connection with mother, or her deputy, propels children to create an inner working pattern (
3). An individual’s relationship with their environment is shaped by experiences and memories from their inner pattern that provide guidelines for connections (
5). The most important principle of attachment theory is that infants need to develop a close relationship with their mother or primary caregiver for successful social and emotional development and for learning to regulate feelings in an effective way (
5). Bowlby recognized three types of attachment styles: secure, anxious and dependent (
5). Studies on sexual offenders have shown that they have had inefficient and unsecure experiences in attachment style (
6); they often develop in unresponsive families (
7). Bowlby believes the origin of criminal behavior is defective attachment (
6,
8).
Another determinant that has an important role in criminal behavior is self-monitoring. Self-monitoring is an ability to see and rate individual behavior that allows a person to evaluate behavioral results versus standards. This ability develops over time (
9). Self-monitoring is rooted in primary learning experiences during childhood in which parents evaluate a child’s behaviors, recognize a child’s abnormal behavior, show the child the consequences of the behavior and punish the false behavior (
9). Defection in any of the stages leads to low self-monitoring. Low self-monitoring people are not concerned with social cues, are impulsive and cannot delay pleasure (
10,
11). Studies have shown that imprisoned sexual offenders have low self-monitoring (
6,
12). Low self-monitoring people are impulsive and focus on immediate and short-term benefits of behavior. They are risk seeking (
13). There is a significant relationship between low self-monitoring and criminal activities (
