Persona Expands Fraud Tools as AI-Driven Identity Fraud Surges
Persona, an identity verification and fraud defense platform, released new data showing a 125% year-over-year increase in high-velocity attacks, where fraudsters use AI and automation to make repeated verification attempts at high speed. The data also reveals that the number of devices associated with high-velocity attacks more than doubled, attackers' devices were linked to 1.5x more IP addresses than legitimate users, and there was an 8x increase in devices cycling through 10 or more IP addresses. In response, Persona is launching new fraud prevention products, including Fraud Fight Flow, Graph link analysis, and Sentinel risk assessment, to help organizations defend against adaptive identity fraud.
The article highlights a growing threat in identity fraud driven by AI, which is relevant for identity verification and fraud prevention in the AdTech ecosystem. However, it is not a major industry shift but rather a product update and data release from a specific vendor.

Infobip: Businesses Scale AI Defenses Against Automated Fraud
Infobip published its 2026 Fraud & Security Report analyzing billions of global interactions and found a sharp rise in AI-powered fraud alongside rapid growth in enterprise defenses. The report states detected threats rose 77% year-over-year while adoption of AI-powered fraud detection grew 71% and pattern-based detection increased 105%. Phishing represented 49% of blocked harmful content (up 94% YoY) and interactions with Network APIs (including SIM swap and number verification) grew 91%, with finance leading adoption. The report highlights customer use — UK retailer NEXT is using Infobip Signals to combat artificially inflated traffic — and includes commentary from Infobip and NEXT executives on the accelerating arms race between automated fraud and AI-driven protection.
Account Fraud and Phishing Surge in 2025
A t3n report highlights a marked rise in account- and card-related fraud, driven by phishing and smishing attacks that increasingly use AI to personalize messages. Germany’s police statistics (PKS) recorded about 96,400 cases around accounts and payment cards in 2025, a ~5% increase year-on-year, and total losses reached roughly €2.25 billion (up ~65%). Detection and prosecution rates remain low: only about 20% of cases overall led to suspects being identified, and cases likely originating abroad had an investigation rate of just 1.4%. Consumer advocates say banks often refuse reimbursements by alleging gross negligence; the Verbraucherzentrale Bundesverband (vzbv) reported a 54% rise in cybercrime complaints related to financial services. Authorities warn the true number of incidents is much higher because many victims do not file reports.
INTERPOL warns AI boosts cyber threat speed and scale
INTERPOL's global CISO Bjorn R. Watne stated that AI is amplifying existing cyber threats like scams and fraud by increasing their speed and scale, rather than creating entirely new types of attacks. He advised companies to identify their most critical assets ('crown jewels') and tailor defenses based on specific threat actors, as not all organizations need to protect against everything. Watne also highlighted the disconnect between senior management and cybersecurity strategy, and expressed particular concern about agentic AI, which can take actions on behalf of users, potentially leading to real-world harm, especially as AI is deployed in physical systems like self-driving cars. He noted that people's high trust in technology, compared to financial services, exacerbates these risks.
