type = detection
asset_type = Endpoint
confidence = medium
explanation = The primary objective of this correlation rule is to detect and alert on potential privilege escalation activities within an organization's Active Directory (AD) environment. By identifying multiple analytics associated with the Active Directory Privilege Escalation analytic story, security analysts can gain better insight into possible threats and respond accordingly to mitigate risks. The correlation rule will trigger an alert when multiple analytics from the Active Directory Privilege Escalation analytic story are detected within a specified time frame. The rule will generate an alert if a predetermined threshold of correlated analytics is reached within the specified time frame. This threshold can be customized to suit the needs and risk appetite of the organization.
how_to_implement = Splunk Enterprise Security is required to utilize this correlation. In addition, modify the source_count value to your environment. In our testing, a count of 4 or 5 was decent in a lab, but the number may need to be increased as the analytic story includes over 30 analytics. In addition, based on false positives, modify any analytics to be anomaly and lower or increase risk based on organization importance.

[savedsearch://ESCU - Windows Ldifde Directory Object Behavior - Rule]
type = detection
asset_type = Endpoint
confidence = medium
explanation = The following analytic identifies the use of Ldifde.exe, which provides the ability to create, modify, or delete LDAP directory objects. Natively, the binary is only installed on a domain controller. However, adversaries or administrators may install the Windows Remote Server Admin Tools for ldifde.exe. Ldifde.exe is a Microsoft Windows command-line utility used to import or export LDAP directory entries. LDAP stands for Lightweight Directory Access Protocol, which is a protocol used for accessing and managing directory information services over an IP network. LDIF, on the other hand, stands for LDAP Data Interchange Format, a standard plain-text data interchange format for representing LDAP directory entries. -i This is a flag used with Ldifde.exe to denote import mode. In import mode, Ldifde.exe takes an LDIF file and imports its contents into the LDAP directory. The data in the LDIF file might include new objects to be created, or modifications or deletions to existing objects. -f This flag is used to specify the filename of the LDIF file that Ldifde.exe will import from (in the case of the -i flag) or export to (without the -i flag). For example, if you wanted to import data from a file called data.ldif, you would use the command ldifde -i -f data.ldif. Keep in mind that while the use of Ldifde.exe is legitimate in many contexts, it can also be used maliciously. For instance, an attacker who has gained access to a domain controller could potentially use Ldifde.exe to export sensitive data or make unauthorized changes to the directory. Therefore, it's important to monitor for unusual or unauthorized use of this tool.

description = Monitor for activities and techniques associated with Privilege Escalation attacks within Active Directory environments.
narrative = Privilege Escalation consists of techniques that adversaries use to gain higher-level permissions on a system or network. Adversaries can often enter and explore a network with unprivileged access but require elevated permissions to follow through on their objectives. Common approaches are to take advantage of system weaknesses, misconfigurations, and vulnerabilities.\
Active Directory is a central component of most enterprise networks, providing authentication and authorization services for users, computers, and other resources. It stores sensitive information such as passwords, user accounts, and security policies, and is therefore a high-value target for attackers. Privilege escalation attacks in Active Directory typically involve exploiting vulnerabilities or misconfigurations across the network to gain elevated privileges, such as Domain Administrator access. Once an attacker has escalated their privileges and taken full control of a domain, they can easily move laterally throughout the network, access sensitive data, and carry out further attacks. Security teams should monitor for privilege escalation attacks in Active Directory to identify a breach before attackers achieve operational success.\

narrative = Exfiltration comes in many flavors. Adversaries can collect data over encrypted or non-encrypted channels. They can utilise Command And Control channels that are already in place to exfiltrate data. They can use both standard data transfer protocols such as FTP, SCP, etc to exfiltrate data. Or they can use non-standard protocols such as DNS, ICMP, etc with specially crafted fields to try and circumvent security technologies in place.
description = Data exfiltration refers to the unauthorized transfer or extraction of sensitive or valuable data from a compromised system or network during a cyber attack. It is a critical phase in many targeted attacks, where adversaries aim to steal confidential information, such as intellectual property, financial records, personal data, or trade secrets.
narrative = This Analytic Story supports you to detect Tactics, Techniques and Procedures (TTPs) leveraged by adversaries to exfiltrate data from your environments. Exfiltration comes in many flavors and its done differently on every environment. Adversaries can collect data over encrypted or non-encrypted channels. They can utilise Command And Control channels that are already in place to exfiltrate data. They can use both standard data transfer protocols such as FTP, SCP, etc to exfiltrate data. Or they can use non-standard protocols such as DNS, ICMP, etc with specially crafted fields to try and circumvent security technologies in place.\
Techniques for getting data out of a target network typically include transferring it over their command and control channel or an alternate channel and may also include putting size limits on the transmission. In context of the cloud, this refers to the unauthorized transfer or extraction of sensitive data from cloud-based systems or services. It involves the compromise of cloud infrastructure or accounts to gain access to valuable information stored in the cloud environment. Attackers may employ various techniques, such as exploiting vulnerabilities, stealing login credentials, or using malicious code to exfiltrate data from cloud repositories or services without detection.

description = This analytic story contains detections that allow security analysts to detect and investigate unusual activities that might relate to the "Volt Typhoon" group targeting critical infrastructure organizations in United States and Guam. The affected organizations include the communications, manufacturing, utility, transportation, construction, maritime, government, information technology, and education sectors. This Analytic story looks for suspicious process execution, lolbin execution, command-line activity, lsass dump and many more.
narrative = Volt Typhoon is a state sponsored group typically focuses on espionage and information gathering.\ Based on Microsoft Threat Intelligence, This threat actor group puts strong emphasis on stealth in this campaign by relying almost exclusively on living-off-the-land techniques and hands-on-keyboard activity. \ They issue commands via the command line to :\ (1) collect data, including credentials from local and network systems, \ (2) put the data into an archive file to stage it for exfiltration, and then \ (3) use the stolen valid credentials to maintain persistence. \ In addition, Volt Typhoon tries to blend into normal network activity by routing traffic through compromised small office and home office (SOHO) network equipment, including routers, firewalls, and VPN hardware. They have also been observed using custom versions of open-source tools to establish a command and control (C2) channel over proxy to further stay under the radar.
