This rule detects the abuse of Azure Virtual Machine Run Command to execute scripts remotely, correlating Azure Activity Log events with endpoint process starts, identifying instances where adversaries use Run Command to run scripts as SYSTEM or root.

This rule identifies suspicious process start events where the parent process matches Azure Virtual Machine Run Command execution patterns on Windows (PowerShell with `-ExecutionPolicy Unrestricted` and `script?.ps1`) or Linux (waagent running `script.sh` under `/var/lib/waagent/run-command/`), exposing on-guest payloads.

CISA published ICS advisories between May 25 and 31, 2026, addressing vulnerabilities across various vendors including ABB, CP Plus, Eppendorf, Frontier, Jinan USR IOT, KMW, MacGregor, Schneider Electric, and XCharge, impacting industrial control systems and related applications.

Dell released security advisories in May 2026 to address vulnerabilities in PowerEdge Server Chipset Driver, Data Lakehouse, Dell Enterprise SONiC Distribution, and Dell Unity/UnityVSA/Unity XT.

The rule detects attempts to clear the kernel ring buffer on Linux systems using the `dmesg` command with options like `-c`, `-C`, `--clear`, or `--read-clear` to evade detection.

Multiple vulnerabilities in JetBrains TeamCity allow an attacker to disclose information, perform a cross-site scripting attack, bypass security measures, and execute arbitrary program code.

A remote, anonymous attacker can exploit multiple vulnerabilities in ImageMagick to cause a denial of service condition, disclose information, and bypass security mechanisms.

A remote, anonymous attacker can exploit a vulnerability in the PostgreSQL JDBC Driver to perform a denial-of-service attack, impacting availability.

Multiple vulnerabilities in IBM Business Automation Workflow can be exploited by an attacker to bypass security measures, conduct a denial of service attack, disclose information, manipulate files, and conduct a cross-site scripting attack.

Multiple vulnerabilities in IBM App Connect Enterprise could allow an attacker to bypass security measures, manipulate data, disclose sensitive information, cause a denial-of-service condition, or perform other unspecified attacks.

This rule detects Linux process executions that reference /etc/kubernetes/manifests in process arguments, which may indicate tampering with static pod manifests for persistence or privilege escalation in Kubernetes environments.

This rule detects Linux process executions that access high-value Kubernetes service-account material, kubeconfig or node PKI paths, or common cloud files, potentially indicating credential theft within in-cluster and hybrid environments.

The creation, modification, or deletion of Kubernetes MutatingWebhookConfigurations or ValidatingWebhookConfigurations by non-system identities can allow attackers to inject malicious sidecars or block security tooling deployments for persistence and defense evasion.

Detects successful AWS AssumeRoleWithWebIdentity where the caller identity is a Kubernetes service account and the source autonomous system organization is not Amazon.com, Inc., potentially indicating a stolen or misused service-account token being used off-cluster.

This rule detects process start events where the parent process is the AWS Systems Manager (SSM) Session Manager worker, which can indicate remote execution and lateral movement by adversaries abusing legitimate AWS credentials.

This brief analyzes a Maltrail IOC list from June 1, 2026, identifying domains and IP addresses associated with various malware and threat actors, including android_fvncbot, lummac2, magentocore, sectoprat, apt_lazarus, offloader, android_joker, cyberstrikeai, and nightshadec2, potentially used for command and control, malware distribution, or phishing campaigns.

A local attacker can exploit multiple vulnerabilities in Fujitsu ServerView to escalate privileges on the targeted system.

A local attacker can exploit a vulnerability in Red Hat Enterprise Linux (crun) to escalate their privileges, potentially gaining root access.

A remote, anonymous attacker can exploit a vulnerability in Notepad++ to execute arbitrary program code, potentially leading to system compromise.

A SQL injection vulnerability (CVE-2026-10226) exists in student_management_system_by_php up to version 310d950e09013d5133c6b9210aff9444382d16d1, allowing remote attackers to execute arbitrary SQL commands by manipulating specific parameters in the delete.php file.

A SQL injection vulnerability exists in raisulislamg4's student_management_system_by_php up to commit 310d950e09013d5133c6b9210aff9444382d16d1, allowing remote attackers to execute arbitrary SQL commands by manipulating the Username argument in login_check.php.

NousResearch hermes-agent up to version 0.12.0 is vulnerable to code injection in the _compress_context function of the run_agent.py file, allowing remote exploitation.

A remote code injection vulnerability (CVE-2026-10220) exists in NousResearch hermes-agent versions up to 2026.4.30, affecting the _serve_plugin_skill/skill_view function in tools/skills_tool.py, potentially allowing attackers to inject arbitrary code.
