A new and powerful Linux Kernel Module (LKM) rootkit named 'Singularity' has been released, reportedly capable of evading most current detection methods. Its features include environment-triggered privilege elevation and hiding processes and files at the syscall level. The availability of such a tool on public platforms like GitHub lowers the barrier for sophisticated attacks against Linux systems.

The China-nexus Advanced Persistent Threat (APT) group, Phantom Taurus, is actively targeting government and telecommunications organizations with a malware variant known as Net-Star. The campaign's objective is espionage, leveraging distinct tactics, techniques, and procedures (TTPs) to exfiltrate sensitive information. This activity represents a persistent nation-state threat to critical infrastructure and government entities.

Researchers have discovered that scammers are abusing unsecured industrial cellular routers manufactured by Milesight IoT to send large volumes of SMS phishing (smishing) messages. These campaigns, ongoing since 2023, exploit vulnerable Internet of Things (IoT) devices to create a distributed and difficult-to-trace infrastructure for phishing attacks. This highlights the growing risk of insecure IoT devices being co-opted for widespread malicious activities.

A new report from Nisos emphasizes the need for proactive monitoring of behavioral, technical, and organizational indicators to identify potential insider threats. As remote work and complex digital environments persist, the risk from insiders (whether malicious or unintentional) remains a critical concern for executives. Establishing a formal insider threat program is a key strategic defense against data loss and sabotage.

Microsoft is highlighting the human element of cybersecurity for Cybersecurity Awareness Month, reinforcing that security is a shared responsibility. For leadership, this is a reminder that technology controls alone are insufficient; a strong security culture, continuous employee training, and awareness campaigns are essential components of a holistic defense strategy. Investing in people is as critical as investing in technology.

Spotlight Rationale: Today's intelligence highlights a landscape rife with unpatched vulnerabilities ([CVE-2025-9230](https://nvd.nist.gov/vuln/detail/CVE-2025-9230), [CVE-2025-9494](https://nvd.nist.gov/vuln/detail/CVE-2025-9494)), targeted attacks on misconfigured servers (UAT-8099), and the abuse of insecure IoT devices. Kexa.io is selected for its proactive, open-source approach to identifying the very misconfigurations that serve as entry points for these threats, directly addressing the root cause of many potential breaches.
Threat Context: Show HN: Kexa.io – Open-Source IT Security Compliance
Platform Focus: Kexa.io Open-Source Cloud Misconfiguration Scanner
Kexa.io provides a unified, open-source solution to scan cloud environments for security misconfigurations. By automating the detection of insecure settings, it directly counters the tactics used by groups like UAT-8099, which exploit improperly configured IIS servers. This proactive stance helps organizations harden their attack surface before vulnerabilities can be exploited, shifting security from a reactive to a preventative model.
Actionable Platform Guidance: Security teams can immediately leverage the open-source version of Kexa.io to perform baseline security assessments of their cloud infrastructure. A key first step is to run a scan focused on public-facing storage and insecure network rules to identify and remediate the most common initial access vectors.

⚠️ Disclaimer: Test all detection logic in non-production environments before deployment.
1. Vendor Platform Configuration - Kexa.io
# Actionable Guidance for Kexa.io Open-Source Scanner
# Goal: Perform a baseline scan for common cloud misconfigurations.
# 1. Install Kexa.io CLI tool (refer to official documentation for specifics)
# Example using npm:
# npm install -g kexa
# 2. Configure cloud provider credentials
# Ensure the environment where you run Kexa has the necessary read-only permissions
# for your AWS, Azure, or GCP environment.
# export AWS_ACCESS_KEY_ID='YOUR_KEY'
# export AWS_SECRET_ACCESS_KEY='YOUR_SECRET'
# export AWS_REGION='us-east-1'
# 3. Run a scan using a predefined ruleset (e.g., CIS benchmarks)
# The command will vary based on the tool's syntax.
# kexa scan --provider aws --ruleset cis-v1.4
# 4. Review the output for high-priority findings
# Focus on publicly exposed resources, missing encryption, and permissive IAM roles.
# 5. Integrate into CI/CD pipeline for continuous monitoring
# Add the scan command as a step in your deployment pipeline to catch
# misconfigurations before they reach production.2. YARA Rule for Singularity LKM Rootkit
