When researchers analyzed how Pegasus spyware infected iPhones without the user tapping anything, they found something wild. The attackers sent an iMessage with a fake GIF that targeted Apple's image decompression engine. The decompression math was so flexible that the exploit

SOAR & Playbook Orchestration Agents

Problem Statement

When a cloud instance (AWS EC2 / Azure VM) exhibits signs of compromise, incident responders must preserve forensic evidence immediately by taking EBS snapshots, dumping RAM, and detaching the server from network routes before the attacker wipes logs or terminates the instance.

Goal

Build an automated SOAR agent that triggers cloud disk snapshots, captures volatile memory metadata, and isolates cloud instances upon detection of high-confidence alerts.

Outcome Measurement

  1. Evidence Preservation: Forensic disk snapshot initiated within 2 seconds of alert.
  2. Chain of Custody: 100% compliance with automated forensic metadata hashing and timestamping.

How the Code was Built

Constructs AWS SDK / Boto3 parameter blocks dynamically for snapshot execution.

Executable Code

from pydantic import BaseModel, Field
from langchain_openai import ChatOpenAI
class CloudForensicsExecution(BaseModel):
instance_id: str
region: str
create_snapshot_command: str
isolate_security_group_command: str
evidence_tagging: dict
def plan_forensic_acquisition(instance_id: str, cloud_region: str, alert_reason: str) -> CloudForensicsExecution:
llm = ChatOpenAI(model="gpt-4o", temperature=0)
structured_llm = llm.with_structured_output(CloudForensicsExecution)
prompt = f"Generate AWS Boto3 automation parameters to isolate cloud instance '{instance_id}' in '{cloud_region}' due to alert: {alert_reason}"
return structured_llm.invoke(prompt)
if __name__ == "__main__":
res = plan_forensic_acquisition("i-0abc1234def56789a", "us-east-1", "Unauthorized Reverse Shell Detected")
print(f"Instance: {res.instance_id}")
print(f"Snapshot Action: {res.create_snapshot_command}")
print(f"Isolation SG: {res.isolate_security_group_command}")
