CISA and FBI Issue Joint Advisory Warning Election Officials of Sophisticated Phishing Threats Ahead of Midterms

BLUFLocal election offices with uneven cyber defenses now bear primary responsibility for countering AI-enhanced credential theft campaigns in the final weeks before the midterms.

The FBI and CISA issued public service announcement I-101626-PSA on October 16, warning that malicious cyber actors may use phishing and smishing to steal credentials and sensitive data from election officials, candidates, and political organizations before the midterms 12. The FBI reported a surge of phishing attempts over the last two election cycles and an increase in smishing through encrypted chat applications within the past year 1. The PSA says actors use "super intelligence" (SI) tools, a term Reuters called Trump-approved for AI, to write convincing messages and deepfakes 13. It urges phishing-resistant multifactor authentication and checking suspicious content for watermarking 1. Inside Cybersecurity noted the PSA follows CISA's September 24 election infrastructure security plan 2.

Analysis
Election offices face AI-polished phishing and encrypted-app smishing in the final weeks before the midterms, and the advisory leaves the defense burden on their own staff and budgets. Credential theft would give actors a path to voter registration data and campaign accounts without touching voting systems. The core asks are phishing-resistant multifactor authentication, secondary-channel verification of requests, and checks for AI content credentials, yet local offices vary widely in the capacity to deliver them. The PSA cites no incident, actor, or campaign, so it describes a general threat environment, not a confirmed operation. It may instead be routine pre-election messaging signaling CISA's renewed election role after the 2025 rollback, not a shift in adversary activity. Confidence is moderate: the primary FBI and CISA document confirms the warning, but trade press and wire coverage repeat it and add no independent evidence of actual intrusions.
