Query: explain T1681 Search Threat Vendor Data
Matching passage: T1681 Search Threat Vendor Data. Tactics: reconnaissance. Description: Threat actors may seek information/indicators from closed or open threat intelligence sources gathered about their own campaigns, as well as those conducted by other adversaries that may align with their target industries, capabilities/objectives, or other operational concerns. These reports may include descriptions of behavior, detailed breakdowns of attacks, atomic indicators such as malware hashes or IP addresses, timelines of a group’s activity, and more. Adversaries may change their behavior when planning their future operations. Adversaries have been observed replacing atomic indicators mentioned in blog posts in under a week.(Citation: Google Cloud Threat Intelligence VMWare ESXi Zero-Day 2023) Adversaries have also been seen searching for their own domain names in threat vendor data and then taking them down, likely to avoid seizure or further investigation.(Citation: Sentinel One Contagious Interview ClickFix September 2025) This technique is distinct from [Threat Intel Vendors](https://attack.mitre.org/techniques/T1597/001) in that it describes threat actors performing reconnaissance on their own activity, not in search of victim information.
Near-miss passage: T1593.003 Code Repositories. Tactics: reconnaissance. Description: Adversaries may search public code repositories for information about victims that can be used during targeting. Victims may store code in repositories on various third-party websites such as GitHub, GitLab, SourceForge, and BitBucket. Users typically interact with code repositories through a web application or command-line utilities such as git. Adversaries may search various public code repositories for various information about a victim. Public code repositories can often be a source of various general information about victims, such as commonly used programming languages and libraries as well as the names of employees. Adversaries may also identify more sensitive data, including accidentally leaked credentials or API keys.(Citation: GitHub Cloud Service Credentials) Information from these sources may reveal opportunities for other forms of reconnaissance (ex: [Phishing for Information](https://attack.mitre.org/techniques/T1598)), establishing operational resources (ex: [Compromise Accounts](https://attack.mitre.org/techniques/T1586) or [Compromise Infrastructure](https://attack.mitre.org/techniques/T1584)), and/or initial access (ex: [Valid Accounts](https://attack.mitre.org/techniques/T1078) or [Phishing](https://attack.mitre.org/techniques/T1566)). **Note:** This is distinct from [Code Repositories](https://attack.mitre.org/techniques/T1213/003), which focuses on [Collection](https://attack.mitre.org/tactics/TA0009) from private and internally hosted code repositories.

Query: CVE similar to CVE-2015-1909
Matching passage: CVE-2015-1909. CWE: CWE-200. CVSS: 5.0. The XML parser in the Reference Data Management component in the server in IBM InfoSphere Master Data Management (MDM) 10.1 before IF1, 11.0 before FP3, 11.3, and 11.4 before FP2 allows remote attackers to read arbitrary files, and consequently obtain administrative access, via an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

Query: SIEM correlation: defense impairment activity consistent with Pluggable Authentication Modules
Matching passage: T1556.003 Pluggable Authentication Modules. Tactics: defense impairment, persistence, credential access. Description: Adversaries may modify pluggable authentication modules (PAM) to access user credentials or enable otherwise unwarranted access to accounts. PAM is a modular system of configuration files, libraries, and executable files which guide authentication for many services. The most common authentication module is <code>pam_unix.so</code>, which retrieves, sets, and verifies account authentication information in <code>/etc/passwd</code> and <code>/etc/shadow</code>.(Citation: Apple PAM)(Citation: Man Pam_Unix)(Citation: Red Hat PAM) Adversaries may modify components of the PAM system to create backdoors. PAM components, such as <code>pam_unix.so</code>, can be patched to accept arbitrary adversary supplied values as legitimate credentials.(Citation: PAM Backdoor) Malicious modifications to the PAM system may also be abused to steal credentials. Adversaries may infect PAM resources with code to harvest user credentials, since the values exchanged with PAM components may be plain-text since PAM does not store passwords.(Citation: PAM Creds)(Citation: Apple PAM)
Near-miss passage: T1556 Modify Authentication Process. Tactics: defense impairment, persistence, credential access. Description: Adversaries may modify authentication mechanisms and processes to access user credentials or enable otherwise unwarranted access to accounts. The authentication process is handled by mechanisms, such as the Local Security Authentication Server (LSASS) process and the Security Accounts Manager (SAM) on Windows, pluggable authentication modules (PAM) on Unix-based systems, and authorization plugins on MacOS systems, responsible for gathering, storing, and validating credentials. By modifying an authentication process, an adversary may be able to authenticate to a service or system without using [Valid Accounts](https://attack.mitre.org/techniques/T1078). Adversaries may maliciously modify a part of this process to either reveal credentials or bypass authentication mechanisms. Compromised credentials or access may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access and remote desktop.

Query: hunt for Input Capture activity
Matching passage: T1056 Input Capture. Tactics: collection, credential access. Description: Adversaries may use methods of capturing user input to obtain credentials or collect information. During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes. Input capture mechanisms may be transparent to the user (e.g. [Credential API Hooking](https://attack.mitre.org/techniques/T1056/004)) or rely on deceiving the user into providing input into what they believe to be a genuine service (e.g. [Web Portal Capture](https://attack.mitre.org/techniques/T1056/003)).
Near-miss passage: T1056.003 Web Portal Capture. Tactics: collection, credential access. Description: Adversaries may install code on externally facing portals, such as a VPN login page, to capture and transmit credentials of users who attempt to log into the service. For example, a compromised login page may log provided user credentials before logging the user in to the service. This variation on input capture may be conducted post-compromise using legitimate administrative access as a backup measure to maintain network access through [External Remote Services](https://attack.mitre.org/techniques/T1133) and [Valid Accounts](https://attack.mitre.org/techniques/T1078) or as part of the initial compromise by exploitation of the externally facing web service.(Citation: Volexity Virtual Private Keylogging)
