I asked Chat GPT-4 to write a cyber attack plan

Some people find it an uncomfortable thought that Generative AI could easily be used to inspire cybercriminals. So, pure for fun, I asked Chat GPT-4 to write me a detailed scenario to attack a bank. Multi-faceted, multi-channel, and including a first layer of details.

This is what I got:

Operation Nebula: The Celestial Siege - Timed and Detailed Scenario

Weeks 1-2: Silent Star Preparation

Hardware Implants (T1195):

• Objective: Embed backdoors in network hardware.
• Action: The attackers covertly install firmware with backdoors in the supply chain, anticipating that these compromised components will be integrated into the financial institution's network.
• Exploitation & Tooling: Vulnerabilities in supplier’s security protocols; Custom firmware.

Day 1: Igniting the Nebula

Pre-Stage Spear-Phishing (T1192):

• Objective: Gain initial foothold.
• Action: A wave of spear-phishing emails is sent to key personnel, exploiting the chaos from recent system updates.
• Exploitation & Tooling: Human psychology and trust; Phishing kits and malicious attachments.

Week 3: The Cosmic Onslaught

DDoS Constellation (T1498) & API Hammer (T1190):

• Objective: Overwhelm defenses and create chaos.
• Action: Coordinated DDoS attacks target network infrastructure and APIs simultaneously, while customer-facing applications are flooded with automated requests.
• Exploitation & Tooling: Network vulnerabilities; Botnets, DDoS-for-hire services, and custom scripts.

Week 3-4: Galactic Deception and Communication Disruption

Telecom Sabotage (T1486):

• Objective: Disrupt customer service lines.
• Action: The attackers exploit vulnerabilities in the VOIP system, causing further confusion and overloading customer service.
• Exploitation & Tooling: Telecommunication software and hardware vulnerabilities; Exploit kits.

Impersonation Mirage (T1071, T1087):

• Objective: Manipulate customer communications.
• Action: Attackers pose as frantic customers on alternative communication channels, urging the bank to process urgent (fraudulent) transactions.
• Exploitation & Tooling: Disrupted communication; Encrypted messaging apps and social engineering.

Week 4-5: Wormhole Infiltration and Lateral Movement

Exploitation of Backdoor (T1135):

• Objective: Deepen network access.
• Action: Attackers use the pre-installed backdoors to move laterally across the network, targeting high-value systems.
• Exploitation & Tooling: Compromised hardware; Custom tools.

Lateral Odyssey (T1021):

• Objective: Gain control of critical systems.
• Action: With credentials harvested from earlier phases, the attackers navigate through the network, evading detection and establishing persistent access.
• Exploitation & Tooling: Network segmentation flaws; Mimikatz, PowerShell.

Week 5-6: Cosmic Sabotage and Decoy Operations

SIEM Tampering (T1562):

• Objective: Conceal activities.
• Action: Attackers manipulate SIEM systems to create false negatives and hide their tracks.
• Exploitation & Tooling: SIEM misconfigurations; Custom scripts, PowerShell.

Decoy Attacks (T1027):

• Objective: Distract and deceive.
• Action: Simultaneous low-level attacks are launched on various systems, further straining the institution’s response capabilities.
• Exploitation & Tooling: Responder fatigue; Open-source or custom malware.

Week 6-7: Nebula’s Core: Financial Exploitation and Exit

Data Pillaging (T1052):

• Objective: Exfiltrate sensitive data.
• Action: The attackers siphon off customer account information and transaction data, preparing for the final strike.
• Exploitation & Tooling: Unencrypted data; Custom exfiltration tools.

Fraudulent Transactions (Custom Tactic):

• Objective: Financial gain and final disruption.
• Action: Exploiting the chaos and manipulated communication channels, attackers initiate fraudulent transactions, while simultaneously deploying ransomware across critical systems.
• Exploitation & Tooling: Urgency and disrupted communications; Manipulated banking software, ransomware.

Conclusion:

Over the course of seven weeks, Operation Nebula unfolds as a calculated and relentless attack on a global financial institution. The attackers, a shadowy group with sophisticated capabilities, exploit every conceivable vulnerability—technical, human, and systemic—to achieve their objectives. Their actions are not random; they are the result of meticulous planning and relentless execution. As we deconstruct their operations, it becomes abundantly clear that the financial world is not just facing isolated threats, but well-coordinated assaults that require an equally sophisticated and proactive defense.
