What a Cluster: Local Volumes Vulnerability in Kubernetes
- Akamai security researcher Tomer Peled recently discovered a high-severity vulnerability in Kubernetes that was assigned CVE-2023-5528 with a CVSS score of 7.2. The vulnerability allows remote code execution with SYSTEM privileges on all Windows endpoints within a Kubernetes cluster. To exploit this vulnerability, the attacker needs to apply malicious YAML files on the cluster. This vulnerability can lead to full takeover on all Windows nodes in a cluster. This vulnerability can be exploited on default installations of Kubernetes (earlier than version 1.28.4), and was tested against both on-prem deployments and Azure Kubernetes Service. In this blog post, we provide a proof-of-concept YAML file as well as an Open Policy Agent (OPA) rule for blocking this vulnerability.
APT28 Hacker Group Targeting Europe, Americas, Asia in Widespread Phishing Scheme

Kubernetes Vulnerability Allows Remote Code Execution on Windows Endpoints
The exploitation of a high-severity Kubernetes vulnerability can lead to arbitrary code execution with System privileges on all Windows endpoints in a cluster, Akamai warns. The issue, tracked as CVE-2023-5528 and impacting default Kubernetes installations, exists in the way the open source container orchestration system processes YAML files, which it uses for virtually every function. In some regards, the vulnerability is like CVE-2023-3676, a lack of sanitization in the subPath parameter in YAML files leading to code injection when creating pods with volumes.
DarkGate Opens Organizations for Attack via Skype, Teams
From July to September, we observed the DarkGate campaign (detected by Trend Micro as TrojanSpy.AutoIt.DARKGATE.AA) abusing instant messaging platforms to deliver a VBA loader script to victims. This script downloaded and executed a second-stage payload consisting of a AutoIT scripting containing the DarkGate malware code. It’s unclear how the originating accounts of the instant messaging applications were compromised, however is hypothesized to be either through leaked credentials available through underground forums or the previous compromise of the parent organization.

Magnet Goblin Targets Publicly Facing Servers Using 1-Day Vulnerabilities
- Magnet Goblin is a financially motivated threat actor that quickly adopts and leverages 1-day vulnerabilities in public-facing services as an initial infection vector. At least in one case of Ivanti Connect Secure VPN (CVE-2024-21887), the exploit entered the group’s arsenal as fast as within 1 day after a POC for it was published. Campaigns that we were able to attribute to this actor targeted Ivanti, Magento, Qlink Sense and possibly Apache ActiveMQ. Analysis of the actor’s recent Ivanti Connect Secure VPN campaign revealed a novel Linux version of a malware called NerbianRAT, in addition to WARPWIRE, a JavaScript credential stealer. * The actor’s arsenal also includes MiniNerbian, a small Linux backdoor, and remote monitoring and management (RMM) tools for Windows like ScreenConnect and AnyDesk.
