First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters
(published: April 21, 2023)
A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign.
Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

3CX Software Supply Chain Compromise Initiated by a Prior Software Supply Chain Compromise; Suspected North Korean Actor Responsible
(published: April 20, 2023)
Investigation of the previously-reported 3CX supply chain compromise (March 2023) allowed Mandiant researchers to detect it was a result of prior software supply chain attack using a trojanized installer for X_TRADER, a software package provided by Trading Technologies. The attack involved the publicly-available tool SigFlip decrypting RC4 stream-cipher and starting publicly-available DaveShell shellcode for reflective loading. It led to installation of the custom, modular VeiledSignal backdoor. VeiledSignal additional modules inject the C2 module in a browser process instance, create a Windows named pipe and |

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Finding Azurescape – Cross-Account Container Takeover in Azure Container Instances
(published: September 9, 2021)
Unit 42 researchers identified and disclosed critical security issues in Microsoft’s Container-as-a-Service (CaaS) offering that is called Azure Container Instances (ACI). A malicious Azure user could have compromised the multitenant Kubernetes clusters hosting ACI, establishing full control over other users' containers. Researchers gave the vulnerability a specific name, Azurescape, highlighting its significance: it the first cross-account container takeover in the public cloud.
Analyst Comment: Azurescape vulnerabilities could have allowed an attacker to execute code on other users' containers, steal customer secrets and images deployed to the platform, and abuse ACI's infrastructure processing power. Microsoft patched ACI shortly after the discl |
