Case Study 2

Startup Acquisition Due Diligence

45-day due diligence period2 senior engineers, 1 week engagement

Background

Scenario: Tech giant acquiring AI startup
Acquisition Value: $150M
Timeline: 45-day due diligence period
ASM Team: 2 senior engineers, 1 week engagement

The Challenge

The acquiring company needed rapid security assessment of the target startup's digital footprint to:

Identify hidden security liabilities
Assess technical debt and remediation costs
Validate security representations in the deal
Plan post-acquisition integration

ASM Methodology

Week 1: Rapid Discovery

# Target company: AI-Startup Inc.
TARGET_DOMAINS="ai-startup.com,aistartup.io,ai-startup.ai"
ASSESSMENT_DIR="ma_assessment_$(date +%Y%m%d)"

mkdir -p "$ASSESSMENT_DIR"/{discovery,analysis,reports}
cd "$ASSESSMENT_DIR"

# Comprehensive asset discovery
for domain in $TARGET_DOMAINS; do
    echo "Discovering assets for: $domain"
    
    # Multiple discovery methods
    subfinder -d "$domain" -all -silent > "discovery/${domain}_subs.txt"
    amass enum -passive -d "$domain" -timeout 15 -o "discovery/${domain}_amass.txt"
    
    # Certificate transparency
    curl -s "https://crt.sh/?q=%.${domain}&output=json" | \
    jq -r '.[].name_value' | sort -u > "discovery/${domain}_ct.txt"
    
    # GitHub code search
    curl -s "https://api.github.com/search/code?q=${domain}" | \
    jq -r '.items[].repository.html_url' > "discovery/${domain}_github.txt"
done

# Consolidate findings
cat discovery/*_subs.txt discovery/*_amass.txt discovery/*_ct.txt | \
sort -u > discovery/all_assets.txt

echo "Total assets discovered: $(wc -l < discovery/all_assets.txt)"

Technology Stack Analysis

# Live service detection with technology profiling
httpx -l discovery/all_assets.txt -tech-detect -status-code -title \
    -content-length -response-time > analysis/live_services.txt

# Extract technology patterns
grep -o 'tech:\[[^]]*\]' analysis/live_services.txt | \
sort | uniq -c | sort -nr > analysis/tech_stack.txt

# Identify concerning technologies
grep -iE "(wordpress|drupal|php/[4-7]|apache/[1-2])" analysis/live_services.txt > analysis/outdated_tech.txt

# Look for development environments
grep -iE "(dev|test|staging|demo|beta)" discovery/all_assets.txt > analysis/dev_environments.txt
