🚨 ShadowV2 is a new botnet campaign that converts misconfigured Docker containers on AWS into a DDoS-for-hire platform. Darktrace’s analysis shows attackers exploiting exposed Docker daemons via the Python Docker SDK, building containers on victims' hosts and deploying a Go-based RAT that polls operators and launches large HTTP floods. The operation is highly professionalized, offering APIs, dashboards, operator logins and modular attack options that make DDoS easily rentable.

⚠️ Researchers at Darktrace disclosed ShadowV2, a DDoS-focused botnet that exploits misconfigured Docker daemons on AWS EC2 instances to deploy a Go-based RAT and enlist hosts as attack nodes. The campaign uses a Python spreader to spawn an Ubuntu setup container, build a custom image, and run an ELF payload that checks in with a Codespaces-hosted C2. Operators leverage HTTP/2 Rapid Reset floods, a Cloudflare UAM bypass via ChromeDP, and a FastAPI/Pydantic operator API, signaling a modular DDoS-for-hire service.

🔒 Akamai researchers reported a June–August 2025 variant that no longer drops a cryptominer but instead leverages exposed Docker APIs to gain persistent host access. The campaign launches lightweight containers that mount the host filesystem and fetch Base64-encoded scripts over Tor to install tools such as curl and tor. Once inside, the malware appends SSH keys, creates cron jobs, and attempts to modify firewall rules to deny others access to port 2375. Akamai also observed dormant logic to probe Telnet and Chrome remote debugging (9222), suggesting future botnet expansion.

🛡️ Attackers are exploiting exposed Docker APIs (port 2375) by launching containers that install Tor and retrieve secondary payloads from hidden services. Researchers at Trend Micro and Akamai observed the activity evolve from opportunistic cryptomining into a more capable dropper that establishes persistent SSH access, creates cron jobs to block API access, and executes a Go-based agent that scans and propagates to additional hosts. The agent also removes competitor containers and contains dormant logic for Telnet and Chrome remote debugging exploitation.

🚨Docker has released an urgent patch for CVE-2025-9074, a critical container escape flaw in Docker Desktop for Windows and macOS that carries a CVSS score of 9.3. A malicious container could reach the Docker Engine API at 192.168.65.7:2375 without authentication, create and start new containers that bind the host C:\ drive and thereby access or modify host files. The issue is fixed in version 4.44.3; Enhanced Container Isolation (ECI) does not mitigate the vulnerability. Linux desktop installations are not affected because they use a host named pipe instead of a TCP socket.
