Byer-Nichols Threat Brief for August 1-15 2026
Threat activity stayed busy in early August, with ransomware crews pushing sharper extortion tactics, cloud-aware espionage groups refining their stealth, and a wave of edge-device and management-tool exploits giving attackers quick footholds. Botnets and stealers kept expanding through unpatched IoT and browser weaknesses, while social-engineering-driven mobile fraud added a fresh twist.

Threat activity in early June picked up across the board, with DeadLock's sharp debut driving over a fifth of observed ransomware activity and mid-market organizations seeing a nearly 38% spike in targeting. Manufacturing held the top sector spot while retail surged to second.
