IR trends Q3 2026: Actors impersonate IT help desks in vishing attacks as ransomware activity increases
Talos Q3 2026 IR data shows ransomware cases climbing, with vishing—particularly IT help-desk impersonation—emerging as a favoured initial-access technique across finance and public-sector targets.
Summary written by editorial AI · Source link below
Phishing remained the leading initial access technique, while percentage of ransomware and pre-ransomware cases increased. Finance and public administration tied as the top-targeted industries.
Editorial Analysis
Vishing-based initial access bypasses technical email controls entirely, meaning organisations without voice-channel verification are exposed despite strong perimeter defences.
Roll out IT help-desk callback-verification procedures and update ransomware incident-response playbooks to include vishing scenarios.
Ransomware is rising again, now often starting with phone-based social engineering that sidesteps email security entirely.
