  • Evaluating the Effectiveness of Two-Factor Authentication (2FA) in Mitigating Account Takeover Fraud

    Open AccessEden Kamar, C Jordan Howell et al.ARTICLECrime & Delinquency2026

    Account takeover fraud involves cybercriminals using stolen credentials to access online accounts, with financial institutions often targeted due to their monetary value. Despite growing adoption, the effectiveness of cybersecurity measures like two-factor authentication (2FA) remains underexplored. This study evaluates 2FA as a target hardening strategy within the situational crime prevention (SCP) framework. Using a natural experimental design,…

    Identity theft targeting American citizens continues to rise. While prior research has linked this trend to data breaches and scams, a more recent development—check theft from U.S. Postal Service (USPS) mailboxes—may also be contributing to the problem.

The first chatbot simulated a sexual…

    The current study employs a construct from the criminological literature, thoughtfully reflective decision-making (TRDM), to understand cyber offenders’ decision-making and offer relevant insights to prevent online harassment. Using a sample of Iranian high school students ( N = 366), we employ OLS and SEM to test whether and how TRDM, perceived deterrence, and prior victimization influence the most common forms of online harassment: cyberbullyin…

To date, no known study has assessed the effectiveness of security messages or whether the effectiveness of these messages varies based on the recipients’ characteristics. Using a randomized controlled trial, this study tests the efficacy of sec…
