T1505: Server Software Component

Persistence Intelligence Profile

AI Answer

Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems. Enterprise server applications may include features that allow developers to write and install software or scripts to extend the functionality of the main application. Adversaries may install malicious components to extend and abuse server applications. (Source: MITRE ATT&CK T1505)

Why it matters

In the OpenTrojan knowledge graph, Server Software Component (T1505) is one of the highest-connectivity ATT&CK techniques: 1 OpenTrojan content pages reference it. These counts are derived from MITRE ATT&CK STIX relationships and are not an estimate of exploitation volume.

How attackers use it

Behavior described below is from the MITRE ATT&CK canonical definition (source: https://attack.mitre.org/techniques/T1505). Adversaries may abuse legitimate extensible development features of servers to establish persistent access to systems. Enterprise server applications may include features that allow developers to write and install software or scripts to extend the functionality of the main application. Adversaries may install malicious components to extend and abuse server applications.
