Human Digital Twins Could Give Attackers a Dangerous Advantage

Human Digital Twins (HDTs) — real-time, predictive virtual clones trained on an individual's behavioral and psychological data — present a growing security risk: attackers could use HDTs to craft hyper-personalized social-engineering campaigns, simulate victims to test attack variants, and impersonate people more convincingly than current deepfakes. The article highlights detection challenges, the amplification of risk from large-scale data breaches that expose voice and behavioral traces, and urges awareness as HDTs become more widespread in consumer and enterprise platforms.
