DripDropper takes advantage of a security hole in ActiveMQ to maintain access to cloud Linux systems and then patches the vulnerability to prevent detection. This technique locks out other malware and conceals its presence. Once inside, it alters SSH configuration files to allow root logins, which gives the attacker extensive control over the compromised server. DripDropper communicates with a Dropbox account using a hardcoded bearer token while employing encrypted binaries that complicate reverse engineering efforts.
DripDropper exploits a known vulnerability in ActiveMQ, allowing persistent access on cloud Linux systems while masking its presence and locking out other malware.
The attacker uses DripDropper to alter SSH configurations, enabling root logins and establishing long-term control through Command and Control frameworks.
