Query: adversary uses Acquire Access
Matching passage: T1650 Acquire Access. Tactics: resource development. Description: Adversaries may purchase or otherwise acquire an existing access to a target system or network. A variety of online services and initial access broker networks are available to sell access to previously compromised systems.(Citation: Microsoft Ransomware as a Service)(Citation: CrowdStrike Access Brokers)(Citation: Krebs Access Brokers Fortune 500) In some cases, adversary groups may form partnerships to share compromised systems with each other.(Citation: CISA Karakurt 2022) Footholds to compromised systems may take a variety of forms, such as access to planted backdoors (e.g., [Web Shell](https://attack.mitre.org/techniques/T1505/003)) or established access via [External Remote Services](https://attack.mitre.org/techniques/T1133). In some cases, access brokers will implant compromised systems with a “load” that can be used to install additional malware for paying customers.(Citation: Microsoft Ransomware as a Service) By leveraging existing access broker networks rather than developing or obtaining their own initial access capabilities, an adversary can potentially reduce the resources required to gain a foothold on a target network and focus their efforts on later stages of compromise. Adversaries may prioritize acquiring access to systems that have been determined to lack security monitoring or that have high privileges, or systems that belong to organizations in a particular sector.(Citation: Microsoft Ransomware as a Service)(Citation: CrowdStrike Access Brokers) In some cases, purchasing access to an organization in sectors such as IT contracting, software development, or telecommunications may allow an adversary to compromise additional victims via a [Trusted Relationship](https://attack.mitre.org/techniques/T1199), [Multi-Factor Authentication Interception](https://attack.mitre.org/techniques/T1111), or even [Supply Chain Compromise](https://attack.mitre.org/techniques/T1195). **Note:** while this technique is distinct from other behaviors such as [Purchase
Near-miss passage: T1683 Generate Content. Tactics: resource development. Description: Adversaries may create or generate content to support targeting and operations. This content may be used to establish personas, impersonate known individuals or organizations, and support [Social Engineering](https://attack.mitre.org/techniques/T1684), fraud, or influence activities. Written materials, audio, images, video, or other media may be developed and tailored to the target and objective.(Citation: IBM AI-Generated Content) Content development may occur prior to or during an operation. Adversaries may develop or generate content in-house, source it through third parties, or produce it using AI-assisted tools. Adversaries may use AI to research targets, develop pretexts, and better understand the organizations and individuals they intend to target or deceive prior to generating content (i.e., [Query Public AI Services](https://attack.mitre.org/techniques/T1682)); for obtaining access to AI tools used in content generation, see [Artificial Intelligence](https://attack.mitre.org/techniques/T1588/007). Content may be leveraged in support of techniques such as [Phishing](https://attack.mitre.org/techniques/T1566), [Phishing for Information](https://attack.mitre.org/techniques/T1598), [Social Engineering](https://attack.mitre.org/techniques/T1684), [Financial Theft](https://attack.mitre.org/techniques/T1657), or [Establish Accounts](https://attack.mitre.org/techniques/T1585).
