July 2025 Fraud Update: Pig Butchering, Voice Impersonation, and Email ATOs

In July 2025, Twilio highlighted emerging fraud trends and shared strategies to combat these challenges, emphasizing its commitment to building a secure platform. The report focused on three major fraud trends: social engineering targeting ISVs, voice impersonation, and account takeovers (ATOs) in email systems. Social engineering has seen a rise, with scammers exploiting ISVs that lack robust Know Your Customer (KYC) checks to conduct pig butchering schemes, where victims are coaxed into investing in fraudulent cryptocurrency platforms. Voice impersonation has also surged, with scammers using AI tools for vishing schemes to extract sensitive information by pretending to be reputable entities. ATOs are a persistent threat, particularly with SendGrid, where compromised accounts are used for crypto and Social Security scams. Twilio advises implementing strong KYC measures, monitoring unusual voice usage, securing API keys, and maintaining up-to-date software to mitigate these risks. The company remains proactive, providing resources and support to help customers protect against fraud, while also urging them to adopt preventive measures independently.
