Phone calls with dubious provenance still flood the North American network. This is the main takeaway of the TNS 2025 Robocall Investigation Report. Over the past year, AI-driven scams have become more sophisticated—employing deepfake voices and disinformation that have caught many off guard. These advanced tactics built on the usual fraudulent schemes, pushing yearly losses close to $80 billion, especially during the heated run-up to the 2024 election.

AI-Driven Tactics Took Center Stage

Voice cloning, targeted phishing, and fabricated fundraising operations proliferated—not simple robocall recordings, but AI-powered calls with eerily convincing human-like voices.

Election Season Fueled Massive Spikes

Robocall volume more than doubled in the final ten days leading up to November 5 and then quadrupled in the last two, creating a perfect storm where legitimate outreach mixed with high-level scams.

Mixed STIR/SHAKEN Adoption

Major carriers have largely implemented STIR/SHAKEN, securing high verification rates. Smaller carriers, however, continue to lag behind, leaving exploitable gaps for fraudsters.

Enterprises Must Stay Vigilant

Shoring up call authentication and addressing the lag in STIR/SHAKEN adoption can help blunt these ever-evolving scams. The better prepared organizations are, the harder it is for criminals to exploit communication networks: an essential focus as AI-driven threats keep advancing.

Finally

The report also shows that the general-purpose nature of AI is becoming the dynamite of our times. In the wrong hands, it can unleash havoc on an unsuspecting consumer population, hence the need for sophisticated, multi-pronged approaches to restoring trust in caller ID.
