Summary

AESDDoS is a botnet used for distributed denial-of-service (DDoS) attacks.

Threat details

At the time of publication, vulnerable systems are added to the AESDDoS by exploiting a known vulnerability (CVE-2019-3396) in Atlassian Confluence Server.

Once a system is enrolled, AESDDoS can extract system information, execute files and commands, and mine cryptocurrency. It may also use the system to perform various types of DDoS attacks. Extracted system information, as well as the command and control data, is encrypted using the AES algorithm.

For further information

Update 17 Jun 2019

A new variant of AESDDoS has been observed targeting misconfigured Docker container APIs. The variant, known as Dofloo, is targeting exposed Docker containers via their daemon. By default, the Docker daemon will listen to TCP 2375 for remote access, traffic sent over this port is unencrypted and unauthenticated. Dofloo exploits this by scanning a given IP range for open ports before requesting root access, if accepted it will then download and execute itself within an existing container.

Remediation steps

Type	Step
	Atlassian addressed the vulnerability used to deliver AESDDoS in Confluence Security Advisory - 2019-03-20. Users and administrators are encouraged to apply this update immediately. Additionally, to prevent and detect an infection, ensure that: All operating systems, anti-virus and other security products are kept up-to-date. Regular anti-virus and security scans are performed on your organisation’s estate. All day-to-day computer activities such as email and internet are performed using non-administrative accounts. Strong password policies are in place. Network, proxy and firewall logs should be monitored for suspicious activity. User accounts accessed from affected devices should be reset on a clean computer. Your organisation adopts a holistic all-round approach to Cyber Security as advocated by the 10 Steps to Cyber Security. Update 17 Jun 2019 By default, the Docker daemon will listen to TCP port 2375 for remote access. Docker have recommended changing disabling this or encrypting the traffic, either through a secure web proxy or Docker's own embedded HTTPS socket (TCP port 2376), in order to prevent access to the daemon.
