CAPEC-662 详情

执行流程

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.

The adversary inserts themself into the communication channel initially acting as a routing proxy between the two targeted components.

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.

前提条件

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.

所需技能

Tricking the victim into installing the Trojan is often the most difficult aspect of this attack. Afterwards, the remainder of this attack is fairly trivial.

缓解措施

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.
