| 摘要 |
An adversary exploits security vulnerabilities or inherent functionalities of a web browser, in order to manipulate traffic between two endpoints. |
| 前置条件 |
The adversary must install or convince a user to install a Trojan. There are two components communicating with each other. An attacker is able to identify the nature and mechanism of communication between the two target components. Strong mutual authentication is not used between the two target components yielding opportunity for adversarial interposition. For browser pivoting, the SeDebugPrivilege and a high-integrity process must both exist to execute this attack. |
| 执行流程 |
| 步骤 |
阶段 |
描述 |
技术手法 |
| 1 |
Experiment |
The adversary tricks the victim into installing the Trojan Horse malware onto their system. |
- Conduct phishing attacks, drive-by malware installations, or masquerade malicious browser extensions as being legitimate.
|
| 2 |
Experiment |
The adversary inserts themself into the communication channel initially acting as a routing proxy between the two targeted components. |
|
| 3 |
Exploit |
The adversary observes, filters, or alters passed data of their choosing to gain access to sensitive information or to manipulate the actions of the two target components for their own purposes. |
|
|
| 解决方案 | Ensure software and applications are only downloaded from legitimate and reputable sources, in addition to conducting integrity checks on the downloaded component. Leverage anti-malware tools, which can detect Trojan Horse malware. Use strong, out-of-band mutual authentication to always fully authenticate both ends of any communications channel. Limit user permissions to prevent browser pivoting. Ensure browser sessions are regularly terminated and when their effective lifetime ends. |

描述
|
| CAPEC-94 |
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components. |
