CAPEC-169 詳細資料

An adversary engages in probing and exploration activities to identify constituents and properties of the target.

執行流程

[Request Footprinting] The attacker examines the website information and source code of the website and uses automated tools to get as much information as possible about the system and organization.

• Open Source Footprinting: Examine the website about the organization and skim through the webpage's HTML source to look for comments.
• Network Enumeration: Perform various queries (Registrar Query, Organizational Query, Domain Query, Network Query, POC Query) on the many whois databases found on the internet to identify domain names and associated networks.
• DNS Interrogation: Once basic information is gathered the attack could begin to query DNS.
• Other Techniques: Use ping sweep, TCP scan, UDP scan, OS Identification various techniques to gain more information about the system and network.

前置條件

An application must publicize identifiable information about the system or application through voluntary or involuntary means. Certain identification details of information systems are visible on communication networks (e.g., if an adversary uses a sniffer to inspect the traffic) due to their inherent structure and protocol standards. Any system or network that can be detected can be footprinted. However, some configuration choices may limit the useful information that can be collected during a footprinting attack.

所需技能

The adversary knows how to send HTTP request, run the scan tool.

所需資源

The adversary requires a variety of tools to collect information about the target. These include port/network scanners and tools to analyze responses from applications to determine version and configuration information. Footprinting a system adequately may also take a few days if the attacker wishes the footprinting attempt to go undetected.

緩解措施

Keep patches up to date by installing weekly or daily if possible.
Shut down unnecessary services/ports.
Change default passwords by choosing strong passwords.
Curtail unexpected input.
Encrypt and password-protect sensitive data.
Avoid including information that has the potential to identify and compromise your organization's security such as access to business plans, formulas, and proprietary documents.
