Match each phase of the cyber kill chain with its correct definition 1. Coupling a remote access trojan with an exploit into a deliverable payload, typically by means of an automated tool (weaponizer). Increasingly, client application data files suchas Adobe Portable Document Format (PDF) or Microsoft Office documents serve as the weaponizeddeliverable.
2. Transmission of the weapon to the targeted environment. The three most prevalentdelivery vectors for weaponized payloads by APT actors, as observed by the Lockheed MartinComputer Incident Response Team (LM-CIRT) for the years 2004-2010, are email attachments, websites, and USB removable media.

3. After the weapon is delivered to victim host, exploitation triggers intruders’ code. Most often, exploitation targets an application or operating system vulnerability, but it could alsomore simply exploit the users themselves or leverage an operating system feature that auto-executescode.

4. Installation of a remote access trojan or backdoor on the victim system allows theadversary to maintain persistence inside the environment.
5. Typically, compromised hosts must beacon outbound to anInternet controller server to establish a C2 channel. APT malware especially requires manualinteraction rather than conduct activity automatically. Once the C2 channel establishes, intrudershave "hands on the keyboard" access inside the target environment.

6. Only now, after progressing through the first six phases, can intruderstake actions to achieve their original objectives. Typically, this objective is data exfiltration whichinvolves collecting, encrypting and extracting information from the victim environment; violationsof data integrity or availability are potential objectives as well. Alternatively, the intruders mayonly desire access to the initial victim box for use as a hop point to compromise additional systemsand move laterally inside the network.

Explanation:

1. Weaponization: Coupling a remote access trojan with an exploit into a deliverable payload,typically by means of an automated tool (weaponizer). Increasingly, client application data files such as Adobe Portable Document Format (PDF) or Microsoft Office documents serve as the weaponized deliverable.

2. Delivery: Transmission of the weapon to the targeted environment. The three most prevalent delivery vectors for weaponized payloads by APT actors, as observed by the Lockheed MartinComputer Incident Response Team (LM-CIRT) for the years 2004-2010, are email attachments,websites, and USB removable media.

3. Exploitation: After the weapon is delivered to victim host, exploitation triggers intruders’ code.Most often, exploitation targets an application or operating system vulnerability, but it could also more simply exploit the users themselves or leverage an operating system feature that auto-executes code.

4. Installation: Installation of a remote access trojan or backdoor on the victim system allows the adversary to maintain persistence inside the environment.

5. Command and Control (C2): Typically, compromised hosts must beacon outbound to an Internet controller server to establish a C2 channel.APT malware especially requires manual interaction rather than conduct activity automatically. Once the C2 channel establishes, intruders have "hands on the keyboard" access inside the target environment.

6. Actions on Objectives: only now, after progressing through the first six phases, can intruders take actions to achieve their original objectives. Typically, this objective is data exfiltration which involves collecting, encrypting and extracting information from the victim environment; violations of data integrity or availability are potential objectives as well. Alternatively, the intruders may only desire access to the initial victim box for use as a hop point to compromise additional systems and move laterally inside the network.
