Coinminer, DDoS Bot Attack Docker Daemon Ports
- clean.sh – Searches for other coin miners and malware to clean/remove. It removes the Kinsing malware, which, according to reports, also targets vulnerable Docker servers.
- dns – The Kaiten/Tsunami DDoS bot
- lan.ssh.kinsing.ssh – Attempts lateral movement via SSH
- NarrenKappe.sh – Configures the firewall to allow ports that will be used by the other components, and sinkholes other domain names by editing the /etc/hosts file. It also exfiltrates sensitive information from its host machine.
- setup.basics.sh – Ensures that the utilities needed by the other components are installed in the system.
- setup.mytoys.sh – Downloads the source code of a log cleaner and compiles it. The script also downloads punk.py, which is a post-exploitation tool that attackers may use to pivot to other devices in the network.
- setup.xmrig.curl.sh – Downloads and installs the coinminer payload.
- sysinfo – Acquires various system information and reports it back to its C&C server.
Misconfigured Docker containers have always been vulnerable to similar threats; attacks using botnets and cryptocurrency miners have also been spotted in the past.

Defense against Docker-related attacks
As more workplaces embrace cloud environments, Docker containers are becoming more popular since they are relatively easy to deploy in a cloud. To protect these containers against attacks, the following practices are advised:
- Host containers in a container-focused OS to lessen the attack surface.
- Use controls such as intrusion prevention systems (IPS) and web filtering to examine network traffic.
- Limit access to only those who need it to lessen the chances of compromise.
- Perform the standard best practices.
Users can also rely on the following security solutions to protect Docker containers:
- Trend Micro Hybrid Cloud Security – provides automated security and protects physical, virtual, and cloud workloads.
- Trend Micro Cloud One™ - provides visibility and protection against threats
- Trend Micro Cloud One™ - Container Security performs automated container image and registry scanning.
- For security as software: Trend Micro Deep Security™ Software (workload and container security) and Trend Micro Deep Security Smart Check (container image security) for scanning container images to detect malware and vulnerabilities early on.
