Attack Tree Path: Compromise Application via FVM Exploitation [CRITICAL NODE]

  • Attack Vector: This is the ultimate goal. Successful exploitation of any of the sub-paths leads to compromising the application that uses FVM.
  • Criticality: Highest criticality as it represents the overall objective of the attacker.

Attack Tree Path: 1. Supply Malicious Flutter SDK [CRITICAL NODE]

  • Attack Vector: The attacker aims to provide a modified Flutter SDK to the developer, which will then be used to build the application, embedding malicious code.
  • Criticality: High criticality because a compromised SDK directly impacts every application built with it.

Attack Tree Path: 1.1. Man-in-the-Middle (MitM) Attack during SDK Download [CRITICAL NODE]

  • Attack Vector: Intercepting the network communication between the developer's machine and the Flutter SDK download server to inject or redirect to a malicious SDK.
  • Criticality: High criticality as it allows for widespread distribution of malicious SDKs if successful against multiple developers.

Attack Tree Path: 1.1.1. Intercept FVM SDK Download Request

  • Attack Vector: Positioning the attacker in the network path to intercept the download request initiated by FVM.
    • 1.1.1.1. Network Level MitM (ARP Spoofing, DNS Spoofing)
      • Attack Vector: Using techniques like ARP or DNS spoofing on a local network to redirect network traffic intended for the legitimate SDK server to the attacker's machine.
    • 1.1.1.2. Compromised Network Infrastructure (e.g., Malicious WiFi)
      • Attack Vector: Exploiting vulnerabilities or malicious configurations in network infrastructure, such as public WiFi hotspots, to perform MitM attacks.

Attack Tree Path: 1.1.1.1. Network Level MitM (ARP Spoofing, DNS Spoofing)

  • Attack Vector: Using techniques like ARP or DNS spoofing on a local network to redirect network traffic intended for the legitimate SDK server to the attacker's machine.

Attack Tree Path: 1.1.1.2. Compromised Network Infrastructure (e.g., Malicious WiFi)

  • Attack Vector: Exploiting vulnerabilities or malicious configurations in network infrastructure, such as public WiFi hotspots, to perform MitM attacks.

Attack Tree Path: 1.1.3. Serve Malicious SDK Content [CRITICAL NODE]

  • Attack Vector: Once the download request is intercepted (via redirection or MitM), the attacker serves a malicious Flutter SDK instead of the legitimate one.
    • 1.1.3.1. Host Malicious SDK on Attacker-Controlled Server
      • Attack Vector: Setting up a server controlled by the attacker to host the malicious SDK and serving it when the intercepted request is redirected.

Attack Tree Path: 1.1.3.1. Host Malicious SDK on Attacker-Controlled Server

  • Attack Vector: Setting up a server controlled by the attacker to host the malicious SDK and serving it when the intercepted request is redirected.

Attack Tree Path: 1.3. Local SDK Replacement (Requires Local Access) [CRITICAL NODE]

  • Attack Vector: If the attacker gains local access to the developer's machine, they can directly replace the legitimate Flutter SDK stored by FVM with a malicious one.
  • Criticality: High criticality as it directly compromises the development environment.

Attack Tree Path: 1.3.1. Gain Unauthorized Access to Developer's Machine

  • Attack Vector: Achieving unauthorized access to the developer's computer.
    • 1.3.1.2. Remote Access via Malware or Exploit
      • Attack Vector: Using malware (trojans, RATs) or exploiting software vulnerabilities to gain remote access to the developer's machine.

Attack Tree Path: 1.3.1.2. Remote Access via Malware or Exploit

  • Attack Vector: Using malware (trojans, RATs) or exploiting software vulnerabilities to gain remote access to the developer's machine.

Attack Tree Path: 1.3.3. Replace Legitimate SDK with Malicious SDK [CRITICAL NODE]

  • Attack Vector: After gaining access and locating the FVM SDK storage, the attacker replaces the legitimate SDK files with a malicious SDK.

Attack Tree Path: 2. Exploit FVM Tool Vulnerabilities [CRITICAL NODE]

  • Attack Vector: Exploiting security vulnerabilities within the FVM tool itself to gain control or execute malicious actions.
  • Criticality: High criticality as vulnerabilities in FVM can directly lead to system compromise or malicious SDK deployment.

Attack Tree Path: 2.1. Command Injection Vulnerability in FVM CLI [CRITICAL NODE]

  • Attack Vector: Exploiting flaws in FVM's command-line interface that allow an attacker to inject and execute arbitrary system commands.
    • 2.1.2. Inject Malicious Commands via Crafted Input
      • Attack Vector: Crafting malicious input strings to FVM commands that, when processed, result in the execution of unintended system commands.
    • 2.1.3. Execute Arbitrary System Commands with FVM's Permissions [CRITICAL NODE]
      • Attack Vector: Successfully injecting commands that are then executed by the system with the privileges of the user running FVM.

Attack Tree Path: 2.1.2. Inject Malicious Commands via Crafted Input

  • Attack Vector: Crafting malicious input strings to FVM commands that, when processed, result in the execution of unintended system commands.

Attack Tree Path: 2.1.3. Execute Arbitrary System Commands with FVM's Permissions [CRITICAL NODE]

  • Attack Vector: Successfully injecting commands that are then executed by the system with the privileges of the user running FVM.

Attack Tree Path: 2.2. Path Traversal Vulnerability in FVM Operations [CRITICAL NODE]

  • Attack Vector: Exploiting vulnerabilities in FVM's file handling that allow an attacker to access or modify files outside of FVM's intended working directories.
    • 2.2.2. Craft Malicious Paths to Access or Modify Files Outside FVM's Intended Scope
      • Attack Vector: Using path traversal sequences (like ../) in input paths to escape intended directories and access files in other parts of the file system.
    • 2.2.3. Overwrite Critical System Files or Application Files [CRITICAL NODE]
      • Attack Vector: Using path traversal to overwrite critical system files, application binaries, or other sensitive data, leading to system instability or compromise.

Attack Tree Path: 2.2.2. Craft Malicious Paths to Access or Modify Files Outside FVM's Intended Scope

  • Attack Vector: Using path traversal sequences (like ../) in input paths to escape intended directories and access files in other parts of the file system.

Attack Tree Path: 2.2.3. Overwrite Critical System Files or Application Files [CRITICAL NODE]

  • Attack Vector: Using path traversal to overwrite critical system files, application binaries, or other sensitive data, leading to system instability or compromise.
