Сбор информации о сетевой инфраструктуре
Sub-techniques (6)
Adversaries may gather information about the victim's networks that can be used during targeting. Information about networks may include a variety of details, including administrative data (ex: IP ranges, domain names, etc.) as well as specifics regarding its topology and operations. Adversaries may gather this information in various ways, such as direct collection actions via Active Scanning or Phishing for Information. Information about networks may also be exposed to adversaries via online or other accessible data sets (ex: Search Open Technical Databases).(Citation: WHOIS)(Citation: DNS Dumpster)(Citation: Circl Passive DNS) Gathering this information may reveal opportunities for other forms of reconnaissance (ex: Active Scanning or Search Open Websites/Domains), establishing operational resources (ex: Acquire Infrastructure or Compromise Infrastructure), and/or initial access (ex: Trusted Relationship).

| Volt Typhoon |
Volt Typhoon has conducted extensive pre-compromise reconnaissance to learn about the target organization’s network.(Citation: CISA AA24-038A PRC Critical Infrastructure February 2024) |
| Indrik Spider |
Indrik Spider has downloaded tools, such as the Advanced Port Scanner utility and Lansweeper, to conduct internal reconnaissance of the victim network. Indrik Spider has also accessed the victim’s VMware VCenter, which had information about host configuration, clusters, etc.(Citation: Mandiant_UNC2165) |
| HAFNIUM |
HAFNIUM gathered the fully qualified domain names (FQDNs) for targeted Exchange servers in the victim's environment.(Citation: Volexity Exchange Marauder March 2021) |

| Pre-compromise |
This category is used for any applicable mitigation activities that apply to techniques occurring before an adversary gains Initial Access, such as Reconnaissance and Resource Development techniques. |
Обнаружение
Much of this activity may have a very high occurrence and associated false positive rate, as well as potentially taking place outside the visibility of the target organization, making detection difficult for defenders. Detection efforts may be focused on related stages of the adversary lifecycle, such as during Initial Access.
