Researchers open-source a Wi-Fi cyber range for security training

Wireless security training programs lean heavily on generic network labs, with Wi-Fi appearing as a checkbox alongside Bluetooth, Zigbee, and cellular. Hands-on environments dedicated to IEEE 802.11 are uncommon, even as Wi-Fi remains the default on-ramp to corporate networks and a recurring entry point for attackers. A new paper from researchers at the Norwegian University…

One in four MCP servers opens AI agent security to code execution risk

Enterprise deployments of AI agents lean on two extension mechanisms that introduce risk at different layers of the stack. MCP servers expose deterministic code functions with structured, loggable invocations. Skills load textual instruction sets directly into a model’s reasoning context, where their effect depends on conversational state and cannot be enumerated the way source code…

GopherWhisper APT group hides command and control traffic in Slack and Discord

Attackers continue to lean on everyday collaboration platforms to hide command and control traffic inside normal enterprise noise. A newly identified China-aligned APT group pushes that trend further, running its operations through Slack workspaces, Discord servers, Outlook drafts, and the file.io sharing service. GopherWhisper toolset overview ESET researchers have named the group GopherWhisper and tied…
