Query: what is T1021.006
Matching passage: T1021.006 Windows Remote Management. Tactics: lateral movement. Description: Adversaries may use [Valid Accounts](https://attack.mitre.org/techniques/T1078) to interact with remote systems using Windows Remote Management (WinRM). The adversary may then perform actions as the logged-on user. WinRM is the name of both a Windows service and a protocol that allows a user to interact with a remote system (e.g., run an executable, modify the Registry, modify services).(Citation: Microsoft WinRM) It may be called with the `winrm` command or by any number of programs such as PowerShell.(Citation: Jacobsen 2014) WinRM can be used as a method of remotely interacting with [Windows Management Instrumentation](https://attack.mitre.org/techniques/T1047).(Citation: MSDN WMI)
Near-miss passage: T1021.005 VNC. Tactics: lateral movement. Description: Adversaries may use [Valid Accounts](https://attack.mitre.org/techniques/T1078) to remotely control machines using Virtual Network Computing (VNC). VNC is a platform-independent desktop sharing system that uses the RFB (“remote framebuffer”) protocol to enable users to remotely control another computer’s display by relaying the screen, mouse, and keyboard inputs over the network.(Citation: The Remote Framebuffer Protocol) VNC differs from [Remote Desktop Protocol](https://attack.mitre.org/techniques/T1021/001) as VNC is screen-sharing software rather than resource-sharing software. By default, VNC uses the system's authentication, but it can be configured to use credentials specific to VNC.(Citation: MacOS VNC software for Remote Desktop)(Citation: VNC Authentication) Adversaries may abuse VNC to perform malicious actions as the logged-on user such as opening documents, downloading files, and running arbitrary commands. An adversary could use VNC to remotely control and monitor a system to collect data and information to pivot to other systems within the network. Specific VNC libraries/implementations have also been susceptible to brute force attacks and memory usage exploitation.(Citation: Hijacking VNC)(Citation: macOS root VNC login without authentication)(Citation: VNC Vulnerabilities)(Citation: Offensive Security VNC Authentication Check)(Citation: Attacking VNC Servers PentestLab)(Citation: Havana authentication bug)

Query: Multiple failed authentications followed by Serverless
Matching passage: T1584.007 Serverless. Tactics: resource development. Description: Adversaries may compromise serverless cloud infrastructure, such as Cloudflare Workers, AWS Lambda functions, or Google Apps Scripts, that can be used during targeting. By utilizing serverless infrastructure, adversaries can make it more difficult to attribute infrastructure used during operations back to them. Once compromised, the serverless runtime environment can be leveraged to either respond directly to infected machines or to [Proxy](https://attack.mitre.org/techniques/T1090) traffic to an adversary-owned command and control server.(Citation: BlackWater Malware Cloudflare Workers)(Citation: AWS Lambda Redirector)(Citation: GWS Apps Script Abuse 2021) As traffic generated by these functions will appear to come from subdomains of common cloud providers, it may be difficult to distinguish from ordinary traffic to these providers - making it easier to [Hide Infrastructure](https://attack.mitre.org/techniques/T1665).(Citation: Detecting Command & Control in the Cloud)(Citation: BlackWater Malware Cloudflare Workers)
Near-miss passage: T1584 Compromise Infrastructure. Tactics: resource development. Description: Adversaries may compromise third-party infrastructure that can be used during targeting. Infrastructure solutions include physical or cloud servers, domains, network devices, and third-party web and DNS services. Instead of buying, leasing, or renting infrastructure an adversary may compromise infrastructure and use it during other phases of the adversary lifecycle.(Citation: Mandiant APT1)(Citation: ICANNDomainNameHijacking)(Citation: Talos DNSpionage Nov 2018)(Citation: FireEye EPS Awakens Part 2) Additionally, adversaries may compromise numerous machines to form a botnet they can leverage. Use of compromised infrastructure allows adversaries to stage, launch, and execute operations. Compromised infrastructure can help adversary operations blend in with traffic that is seen as normal, such as contact with high reputation or trusted sites. For example, adversaries may leverage compromised infrastructure (potentially also in conjunction with [Digital Certificates](https://attack.mitre.org/techniques/T1588/004)) to further blend in and support staged information gathering and/or [Phishing](https://attack.mitre.org/techniques/T1566) campaigns.(Citation: FireEye DNS Hijack 2019) Adversaries may also compromise numerous machines to support [Proxy](https://attack.mitre.org/techniques/T1090) and/or proxyware services or to form a botnet.(Citation: amnesty_nso_pegasus)(Citation: Sysdig Proxyjacking) Additionally, adversaries may compromise infrastructure residing in close proximity to a target in order to gain [Initial Access](https://attack.mitre.org/tactics/TA0001) via [Wi-Fi Networks](https://attack.mitre.org/techniques/T1669).(Citation: Nearest Neighbor Volexity) By using compromised infrastructure, adversaries may enable follow-on malicious operations. Prior to targeting, adversaries may also compromise the infrastructure of other adversaries.(Citation: NSA NCSC Turla OilRig)
