Social engineering attacks were responsible for 65% of cryptocurrency thefts in 2025, leading to $17 billion in fraud losses, according to a Chainalysis report. These attacks exploit user trust and urgency rather than targeting blockchain technology directly. Common tactics include phishing, impersonation scams, SIM swapping, and AI-driven scams. Chainalysis highlighted that AI-enabled scams averaged $3.2 million per operation, significantly higher than traditional scams. The U.S. FBI reported 22,364 complaints related to AI-assisted crypto scams in 2025, with losses totaling $893 million. Users are advised to avoid SMS verification codes, verify identities through official channels, and regularly review wallet authorizations to mitigate risks.
