Short-term memory, verbal fluency, and positive affect in middle-old age may contribute to resilience against online spear-phishing attacks. These results inform mechanisms of online fraud susceptibility and real-life decision-supportive interventions towards fraud risk reduction in aging.

Phishing is fundamental to cyber attacks. This research determined the effect of Internet user age and email content such as weapons of influence (persuasive techniques that attackers can use to lure individuals to fall for an attack) and life domains (a specific topic or aspect of an individual's life that attackers can focus an email on) on spear-phishing (targeted phishing) susceptibility. In total, 100 young and 58 older users received, without their knowledge, daily simulated phishing emails over 21 days. A browser plugin recorded their clicking on links in the emails as an indicator of their susceptibility. Forty-three percent of users fell for the simulated phishing emails, with older women showing the highest susceptibility. While susceptibility in young users declined across the study, susceptibility in older users remained stable. The relative effectiveness of the attacks differed by weapons of influence and life domains with age-group variability. In addition, older compared to young users reported lower susceptibility awareness. These findings support effects of Internet user demographics and email content on susceptibility to phishing and emphasize the need for personalization of the next generation of security solutions.

Spear phishing emails are key in many cyber attacks. Successful emails employ psychological weapons of influence and relevant life domains. This paper investigates spear phishing susceptibility as a function of Internet user age (old vs young), weapon of influence, and life domain. A 21day study was conducted with 158 participants (younger and older Internet users). Data collection took place at the participants' homes to increase ecological validity. Our results show that older women were the most vulnerable group to phishing attacks. While younger adults were most susceptible to scarcity, older adults were most susceptible to reciprocation. Further, there was a discrepancy, particularly among older users, between self-reported susceptibility awareness and their behavior during the intervention. Our results show the need for demographic personalization for warnings, training and educational tools in targeting the specifics of the older adult population 1 .

Objective: Digital mental health interventions (DMHIs) are typically designed as “one-size fits all” which may perpetuate health disparities for racialized minorities. This systematic review identified culturally adapted DMHIs and examined their efficacy and acceptability among racial and ethnic minorities. Method: PsycINFO, Web of Science, and Pubmed databases were searched between 2000 and 2021. Studies that examined the development or impact of a culturally adapted DMHI for racial or ethnic minority populations using quantitative and/or qualitative methodologies were included. Meta-analyses explored the efficacy of DMHIs, and moderator analyses were used to identify differences in effect sizes due to study quality, clinical outcomes, therapist support, and attrition. Results: Thirty-two studies met inclusion criteria and were reviewed. DMHIs were deemed acceptable and feasible in most studies (n = 24). Among eligible randomized controlled studies (n = 12) comprising 653 participants, results indicated that culturally adapted DMHIs produced a large, positive, significant effect (g = 0.90) across a range of outcomes when compared to wait-list and treatment as usual control conditions. The average attrition rate per study was 42%, and most participants did not complete all modules despite reporting high satisfaction. Conclusions: Culturally adapted DMHIs are efficacious and acceptable. Such interventions represent a powerful opportunity to circumvent barriers to mental health treatment and improve mental health equity among racially and ethnically minoritized communities. However, the prevalence of feasibility studies, lack of active comparison treatments—and limited research for Black and Indigenous populations—indicate that more research is needed to achieve this purpose. Recommendations are discussed.
