ESET's WeLiveSecurity warns that AI and large language models (LLMs) now automate OSINT reconnaissance at machine speed. Profiling that once took a skilled attacker hours or days can be done by low-skill actors, so ordinary internet users are now economically viable fraud targets.

The flood hid a genuine bank alert about a fraudulent laptop purchase. Attackers use bots to sign a harvested email address up to many legiti…
This ESET blog post argues that AI is speeding up the threat landscape for SMBs, both by empowering threat actors and by widening the attack surface as businesses adopt AI faster than they govern it. The ESET SMB Cyber Readiness Index 2026 reports that 73% of SMBs are integrating AI, 40% lack a proper AI policy, and 45% suffered a cyberse…
ESET analysis describes a two-pronged risk for small and mid-size businesses (SMBs): AI agents create new paths into business systems, while attackers use AI to add speed and scale to established threats. Between March and May 2026, ESET scanned almost 900,000 unique agent skills from popular repositories and found more than 25,000 suspic…
