Suspicious LNK Command-Line Padding with Whitespace Characters

Apr 16, 2025 · attack.initial-access attack.execution attack.t1204.002 ·
Share on:

Detects exploitation of LNK file command-line length discrepancy, where attackers hide malicious commands beyond the 260-character UI limit while the actual command-line argument field supports 4096 characters using whitespace padding (e.g., 0x20, 0x09-0x0D). Adversaries insert non-printable whitespace characters (e.g., Line Feed \x0A, Carriage Return \x0D) to pad the visible section of the LNK file, pushing malicious commands past the UI-visible boundary. The hidden payload, executed at runtime but invisible in Windows Explorer properties, enables stealthy execution and evasion—commonly used for social engineering attacks. This rule flags suspicious use of such padding observed in real-world attacks.

Share on:

Detects when an attacker tries to change User Account Control (UAC) elevation request destination via the "PromptOnSecureDesktop" value. The "PromptOnSecureDesktop" setting specifically determines whether UAC prompts are displayed on the secure desktop. The secure desktop is a separate desktop environment that's isolated from other processes running on the system. It's designed to prevent malicious software from intercepting or tampering with UAC prompts. When "PromptOnSecureDesktop" is set to 0, UAC prompts are displayed on the user's current desktop instead of the secure desktop. This reduces the level of security because it potentially exposes the prompts to manipulation by malicious software.

Azure Kubernetes Admission Controller

Aug 12, 2024 · attack.persistence attack.t1078 attack.credential-access attack.t1552 attack.t1552.007 ·
Share on:

Identifies when an admission controller is executed in Azure Kubernetes. A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server. The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster. An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster. For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod. An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials. An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.

Directory Service Restore Mode(DSRM) Registry Value Tampering

Aug 12, 2024 · attack.persistence attack.t1556 ·
Share on:

Detects changes to "DsrmAdminLogonBehavior" registry value. During a Domain Controller (DC) promotion, administrators create a Directory Services Restore Mode (DSRM) local administrator account with a password that rarely changes. The DSRM account is an “Administrator” account that logs in with the DSRM mode when the server is booting up to restore AD backups or recover the server from a failure. Attackers could abuse DSRM account to maintain their persistence and access to the organization's Active Directory. If the "DsrmAdminLogonBehavior" value is set to "0", the administrator account can only be used if the DC starts in DSRM. If the "DsrmAdminLogonBehavior" value is set to "1", the administrator account can only be used if the local AD DS service is stopped. If the "DsrmAdminLogonBehavior" value is set to "2", the administrator account can always be used.

Google Cloud Kubernetes Admission Controller

Aug 12, 2024 · attack.persistence attack.t1078 attack.credential-access attack.t1552 attack.t1552.007 ·
Share on:

Identifies when an admission controller is executed in GCP Kubernetes. A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server. The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster. An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster. For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod. An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials. An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.
