Summary

A new malware targeting Linux-based Internet of Things (IoT) devices known as ELF_IMEIJ.A targets vulnerabilities identified in surveillance cameras produced by the company AVTech to carry out DDoS attacks.

Threat details

The points of entry for this malware are devices that support the AVTech cloud environment, specifically IP cameras, CCTV and network recorders.

Vulnerable IoT devices are identified via cig-bin scripts that will ping IP addresses on a network until it finds a weak spot. Once identified it exploits the CloudSetup.cgi and executes a command injection which will then result in the malware being downloaded.

After successful installation the file’s permissions are then changed to execute the file locally and perform the DDoS attack. It’s been identified that all passwords on AVTech products are stored in clear text and an attacker will have the ability to see all of the passwords stored on the device.


Remediation steps

Type Step
  • Identify whether there is a presence of any AVTech products.
  • Look to ensure that any AVTech products are excluded from the main network and any access from the internet.
  • Ensure that default passwords on all devices are changed.
