Performing Cloud Forensics With Aws Cloudtrail

Overview

Cybersecurity skill for performing cloud forensics with aws cloudtrail. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing cloud forensics with aws cloudtrail"

• "Perform forensic investigation of AWS environments using CloudTrail logs to reco"

• When investigating suspected AWS account compromise

• After detecting unauthorized API calls or credential exposure

• During incident response involving cloud infrastructure

• When analyzing S3 data exfiltration or IAM privilege escalation

• For post-incident forensic timeline reconstruction

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• AWS account with CloudTrail enabled (management and data events)
• IAM permissions for cloudtrail:LookupEvents, s3:GetObject, athena:StartQueryExecution
• boto3 Python SDK installed
• CloudTrail logs delivered to S3 with optional Athena table configured
• AWS CLI configured with appropriate credentials

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

1. Plan Operations — Define objectives, scope, and success criteria for cloud forensics operations.
2. Prepare Environment — Set up tools, access, and data sources required for cloud forensics.
3. Execute Core Workflow — Use aws cloudtrail to perform cloud forensics operations following established procedures.
4. Validate Results — Verify that results meet quality standards and objectives.
5. Report Findings — Document results, observations, and recommendations.
6. Follow Up — Track remediation actions and verify fixes where applicable.

Tools

• aws cloudtrail — Primary tool for this skill
• Analysis Platform — Data processing and visualization
• Collaboration Tools — Team coordination and knowledge sharing

Process

1. Reconnaissance — Gather target information, identify attack surface, enumerate services
2. Analysis/Exploitation — Execute the technique, analyze results, document findings
3. Reporting — Document IOCs, write findings, provide remediation recommendations

Verification

• All cloud forensics procedures executed completely and documented
• Findings validated against multiple data sources
• False positives identified and filtered
• Results documented with evidence and timestamps
• Recommendations provided with risk-based prioritization
