Dear Adversaries: We See You

To the **172.212.163.225** (US - cheapyhost proxy), **45.142.212.61** (Netherlands - residential VPN), **103.149.88.17** (Singapore - "anonymous" datacenter), and the **hundreds of other IPs** trying to scan our infrastructure:

**Thank you for your polite interest in what we and everyone on the planet is up to on the interwebz.**

Your persistent attempts to enumerate our attack surface, brute-force authentication endpoints, and probe for vulnerabilities have been **meticulously logged, analyzed, and added to our Hall of Shame**.

This blog post is our **thank you card** - complete with receipts.

The Bot Traffic Reality: Real Percentages from Production

If you're building an app after layoffs (or bootstrapping a startup), **you need to know these numbers**.

Our Infrastructure (Context)

- **Platform:** analytics.dugganusa.com (Azure Container Apps)

- **Tech Stack:** Node.js + Cloudflare CDN + AbuseIPDB threat intel

- **Deployment:** Single microservice, public-facing dashboard

- **Target Audience:** Security professionals, technical founders

- **Monthly Traffic:** ~5,000 pageviews (legitimate analytics traffic)

Bot Traffic Breakdown (Last 30 Days)

**Total Requests Received:** 47,283

**Legitimate Human Traffic:** 5,124 (10.8%)

**Bot Traffic:** 42,159 (89.2%)

Let that sink in: **9 out of 10 requests to our infrastructure are bots**.

---

The Adversaries: Categorized with Receipts

Category 1: Script Kiddies (35% of bot traffic)

**Characteristics:**

- Scanning for `/wp-admin`, `/phpmyadmin`, `/.env` files

- User-Agent: `Mozilla/5.0` (spoofed, but obvious)

- Source: Cheap VPS providers, compromised home routers

**Example IP:** `103.149.88.17` (Singapore)

- **ISP:** "Shock Hosting" (red flag in the name)

- **AbuseIPDB Score:** 87% (highly malicious)

- **Total Reports:** 1,247 (reported by 89 different networks)

- **Attack Types:** Port scanning, brute force attempts

- **MITRE Technique:** T1071 - Application Layer Protocol

**Our Response:** Auto-blocked via Cloudflare IP Lists (7-day cache, feather-light API usage)

**The Receipt:**

**Shame Level:** 🔥🔥🔥 (Script kiddie with rented infrastructure)

---

Category 2: Residential Proxies (28% of bot traffic)

**Characteristics:**

- Rotating IPs from ISPs like Comcast, Verizon, AT&T

- Purpose: Bypass geo-restrictions, evade rate limiting

- Source: Compromised home routers, mobile malware, "proxy services"

**Example IP:** `45.142.212.61` (Netherlands)

- **ISP:** "Residential Proxy Network B.V." (not even hiding it)

- **AbuseIPDB Score:** 23% (moderate, but suspicious usage pattern)

- **Usage Type:** Residential proxy

- **MITRE Technique:** T1090 - Proxy

**Why This Matters:**

Cloudflare Pro ($240/year) **doesn't detect residential proxies**. Their WAF sees `Comcast` ISP and assumes "legitimate home user." We wrote our own detection:

**Cost of Detection:** $0 (15 lines of JavaScript)

**Cost of Cloudflare's Blind Spot:** Unquantified (but they charge $240/year for Pro)

**The Receipt:**

**Shame Level:** 🔥🔥 (Professional adversary, not script kiddie)

---

Category 3: Command & Control (C2) Infrastructure (18% of bot traffic)

**Characteristics:**

- Young domains (< 90 days old)

- DNS patterns consistent with Domain Generation Algorithms (DGA)

- High VirusTotal detections

- ThreatFox IOC matches

**Example IP:** `172.212.163.225` (US)

- **ISP:** "cheapyhost.com" (yes, really)

- **AbuseIPDB Score:** 91%

- **Domain Age:** 14 days (registered 2025-10-12)

- **VirusTotal Detections:** 12/94 engines flagged as malicious

- **MITRE Technique:** T1568 - Dynamic Resolution

**Why Domain Age Matters:**

Legitimate businesses don't register domains 2 weeks ago and immediately start port scanning. C2 infrastructure rotates domains frequently to evade blocklists.

**Our Detection:**

**The Receipt:**

**Shame Level:** 🔥🔥🔥🔥 (Active C2 infrastructure, reported to ThreatFox)

---

Category 4: Cloud Provider Abuse (12% of bot traffic)

**Characteristics:**

- AWS, GCP, Azure, DigitalOcean IPs

- Legitimate infrastructure, malicious usage

- Often: Compromised accounts, stolen credit cards

**Example IP:** `34.227.92.15` (AWS us-east-1)

- **ISP:** Amazon Data Services

- **AbuseIPDB Score:** 34%

- **Attack Type:** Credential stuffing (500+ login attempts/minute)

- **MITRE Technique:** T1102 - Web Service (abusing legitimate cloud)

**Why This Is Hard:**

You can't just block "all of AWS" - your legitimate customers use AWS too. Our approach:

1. **Behavioral analysis:** 500 login attempts/minute ≠ human

2. **AbuseIPDB cross-reference:** Is this specific AWS IP reported?

3. **Temporary block:** 24-hour sin bin, not permanent ban

**The Receipt:**

**Shame Level:** 🔥🔥 (Compromised cloud account, not Amazon's fault)

---

Category 5: "Security Researchers" (7% of bot traffic)

**Characteristics:**

- Shodan, Censys, BinaryEdge scanners

- User-Agent: Explicitly identifies as scanner

- Purpose: Internet-wide enumeration

**Example IP:** `198.108.66.108` (Shodan)

- **ISP:** Shodan Internet Census

- **AbuseIPDB Score:** 0% (whitelisted by community)

- **Blocked:** No (we allow legitimate research)

**Our Stance:**

We **don't block** Shodan, Censys, or other legitimate security research platforms. They're mapping the internet's attack surface - that's a public service.

**The Receipt:**

**Shame Level:** ✅ (No shame - thank you for your service)

---

The Real Percentages: What Every Founder Needs to Know

If You're Building an App After Layoffs...

**Expect this breakdown:**

- **10% legitimate human traffic** (your actual users)

- **35% script kiddies** (scanning for low-hanging fruit)

- **28% residential proxies** (credential stuffing, scraping)

- **18% C2 infrastructure** (malware phone-home, data exfiltration)

- **12% cloud abuse** (compromised accounts)

- **7% security research** (Shodan, Censys - allow these)

**Translation:**

If you see "10,000 requests/day" in your logs, **only 1,000 are real users**. The other 9,000 are adversaries.

Cost of Ignoring This

**Scenario:** You're on Heroku/Vercel/Railway free tier (10,000 requests/month limit)

- **Month 1:** You hit the limit in 3 days (90% bot traffic)

- **Month 2:** You upgrade to paid tier ($25/month)

- **Month 3:** Bots scale, you're at $100/month

- **Month 6:** You're paying $500/month for infrastructure **serving 90% bots**

**Our Approach:**

- **Cost:** $130/month (Azure Container Apps)

- **Bot Filtering:** Cloudflare IP Lists + AbuseIPDB (free tier, feather-light usage)

- **Actual Infrastructure Serving Real Users:** ~$13/month (10% of requests)

- **Cost to Serve Bots:** $0 (blocked at edge)

**ROI on 30 minutes of threat intel integration:** $370/month savings ($4,440/year)

The MITRE ATT&CK Kill Chain: What Adversaries Are Doing

Every blocked IP is now mapped to the **MITRE ATT&CK framework** (TA0011 Command & Control focus):

Top 5 Techniques Observed (Last 30 Days)

1. **T1071 - Application Layer Protocol** (45%)

- Embedding attacks in HTTP/HTTPS traffic

- Example: SQL injection in query parameters

2. **T1090 - Proxy** (28%)

- Routing traffic through residential proxies

- Evading geo-blocks and rate limits

3. **T1568 - Dynamic Resolution** (18%)

- DGA domains, fast-flux DNS

- C2 infrastructure rotation

4. **T1102 - Web Service** (7%)

- Abusing legitimate cloud services

- Compromised AWS/GCP/Azure accounts

5. **T1573 - Encrypted Channel** (2%)

- TLS-wrapped malicious traffic

- Suspicious certificates

**What This Means:**

Your WAF needs to understand **behavioral patterns**, not just signature matching. A request from "Amazon AWS" with "Mozilla/5.0" user-agent making 500 requests/minute is **not a human**.
