Kinsing Actors Target Cloud Environments Exploiting Looney Tunables
Recently, there has been a concerning development in the world of cloud security. A group of threat actors linked to Kinsing is actively targeting cloud environments. They are doing this by taking advantage of a newly disclosed Linux privilege escalation flaw called Looney Tunables.
In their new experimental campaign to breach cloud environments, these threat actors are not just stopping at Looney Tunables. They have expanded their tactics by extracting credentials from Cloud Service Providers (CSPs), as the cloud security firm Aqua reported. This is a significant shift from their usual pattern of deploying Kinsing malware and launching cryptocurrency mining operations.
Looney Tunables, tracked as CVE-2023-4911, is a buffer overflow vulnerability in glibc that could allow a threat actor to gain root privileges. This marks the first documented instance of active exploitation of this vulnerability.
Conclusion: Securing Cloud Environments
The ultimate goal of this attack appears to be the extraction of credentials associated with the cloud service provider, signaling a significant shift in the tactics of these threat actors. Instead of solely focusing on cryptocurrency mining, they are actively seeking sensitive information.
Security researcher Assaf Morag noted that this recent development suggests a potential broadening of their operational scope, which could pose an increased threat to cloud-native environments in the near future. Organizations need to stay vigilant and take steps to protect their cloud environments from these evolving threats.
