Oligo researchers found that an old critical vulnerability tracked as CVE-2023-48022 was exploited in both campaigns... The attacks leverage CVE-2023-48022 to submit jobs to Ray’s unauthenticated Jobs API to run multi-stage Bash and Python payloads...
Groups observed using it
1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
It can also launch DDoS attacks using the Sockstress tool, which exploits asymmetric resource consumption by opening large numbers of TCP connections through raw sockets.
Techniques & procedures
4 distinct techniques documented for this family, organized by ATT&CK tactic.
Initial Access
1 technique“ShadowRay 2.0 hijacks exposed Ray Clusters by exploiting an old code execution flaw… CVE-2023-48022… leverage CVE-2023-48022 to submit jobs to Ray’s unauthenticated Jobs API to run multi-stage Bash and Python payloads”
Command and Control
1 technique“observed two attack waves, one that abused GitLab for payload delivery… and one that abuses GitHub… a script is executed every 15 minutes to check the GitHub repository for updated payloads.”
Impact
2 techniques“deploying distributed denial-of-service (DDoS) attacks… launch DDoS attacks using the Sockstress tool… opening large numbers of TCP connections through raw sockets.”
Attackers deployed sockstress, a TCP state exhaustion tool, targeting production websites. This suggests the compromised Ray clusters are being weaponized for denial-of-service attacks...
