Apology to the Innocents: When Threat Intel Catches Legitimate Traffic

# Apology to the Innocents: When Threat Intel Catches Legitimate Traffic

**Author:** Patrick Duggan (DugganUSA LLC)

**Evidence:** threat-intel-export-2025-10-27.csv (Yesterday's scan)

**Lesson:** The Internet is Broken. We're Sorry for the Inconvenience.

The Apology We Never See in Security

**Most security vendors will tell you:**

"Our threat intelligence has 99.99% accuracy! Zero false positives! Machine learning perfection!"

**We tell you:**

"We caught some innocents in the net. We're sorry. Here's the evidence of what's broken."

**This post is for the collateral damage.**

The Evidence of a Broken Internet (October 27, 2025)

**Yesterday, we scanned 81 IPs that touched dugganusa.com.**

**Here's what we found that SHOULD be clean but looks suspicious:**

Exhibit A: Google DNS (8.8.8.8)

**165 abuse reports against Google's public DNS resolver.**

**Why it looks suspicious:** Volume. 165 reports sounds BAD.

**Why it's actually clean:** AbuseIPDB weighted scoring correctly identifies this as legitimate infrastructure.

**If we used simple volume-based blocking:** We would have blocked Google DNS and broken half the internet.

**Apology:** To anyone using our threat intel who saw "165 reports" and got nervous - we're sorry for the heart attack. Google DNS is fine. The internet is just noisy.

---

Exhibit B: Microsoft Azure CDN (40.88.21.235)

**219 abuse reports. HIGHER than Google DNS.**

**Why it looks suspicious:** That's a LOT of reports.

**Why it's actually clean:** Azure CDN serves millions of websites. High traffic = high report volume (mostly false positives).

**If we used simple volume-based blocking:** We would have blocked half of Microsoft's CDN and taken down thousands of legitimate websites.

**Apology:** To Microsoft Azure customers who saw their CDN flagged in our logs - we didn't block you. We promise. The scoring algorithm works.

---

Exhibit C: Googlebot (66.249.79.168)

**7 abuse reports against Google's web crawler.**

**Why it looks suspicious:** It's crawling websites. Aggressively. Some admins hate crawlers.

**Why it's actually clean:** Googlebot is how Google indexes the web. Blocking it = Goodbye SEO.

**If we used overzealous bot detection:** We would have blocked Googlebot and destroyed our search rankings.

**Apology:** To Google engineers reading our surveillance logs wondering why Googlebot showed up as "suspicious traffic" - we didn't block you. We know you're doing your job. Keep crawling.

The False Positive Problem (Why 100% Accuracy is a Lie)

**Let's do the math on yesterday's scan:**

Our Classification

What "SUSPICIOUS" Actually Means

**8 IPs scored between 25-74 (our SUSPICIOUS range):**

1. `165.22.3.253` (US): Score 45, 6 reports, 0 VT

2. `178.128.89.25` (SG): Score 52, 27 reports, 1 VT

3. `193.17.44.106` (UA): Score 65, 214 reports, 2 VT

4. `196.251.72.91` (NL): Score 30, 4 reports, 8 VT (!!!)

5. `3.39.226.199` (KR): Score 37, 12 reports, 0 VT

6. `45.154.153.23` (FR): Score 28, 4 reports, 0 VT

7. `8.217.211.42` (HK): Score 42, 56 reports, 1 VT

8. `8.217.212.86` (HK): Score 43, 55 reports, 1 VT

**These IPs are in purgatory.**

**Not clean enough to whitelist. Not malicious enough to block.**

**This is where innocent traffic gets caught.**

---

Apology #1: To the DigitalOcean Developer (165.22.3.253)

**You're probably a developer.**

You spun up a DigitalOcean droplet to test your API integration with dugganusa.com. You made 6 requests. You left.

**But here's the problem:**

- DigitalOcean = Popular with developers AND botnet operators

- 6 reports = Low volume, but not zero

- No VirusTotal detections = Probably clean

- Score 45 = Right on the borderline

**What we did:** Monitored but didn't block. Your requests went through.

**What amateur threat intel would do:** Block all DigitalOcean IPs (score > 40). Your dev environment breaks. You waste 2 hours debugging before realizing it's a false positive.

**Apology:** Sorry for the surveillance. We logged your 6 requests. We analyzed them. We decided you're probably human. But we're still watching. Because the internet is broken and we can't tell developers from botnets without watching for a while.

**The inconvenience we caused:** None (you got through). But you showed up in our logs as "SUSPICIOUS" and if you're reading this, now you know why.

---

Apology #2: To the Ukraine IP with 214 Reports (193.17.44.106)

**You're in a tough spot.**

- Ukraine = War zone (infrastructure chaos)

- 214 reports = High volume (probably compromised at some point)

- VirusTotal 2/95 = Two engines flagged you

- Score 65 = Suspicious but not confirmed malicious

**What we think happened:**

1. Your ISP got compromised in 2022 (Russian cyber attacks)

2. Your IP was part of a botnet (briefly)

3. The botnet got cleaned up

4. But the reports persist (AbuseIPDB has a long memory)

5. Now you're trying to access legitimate websites and getting flagged

**What we did:** Monitored but didn't block. Your requests went through.

**What overzealous threat intel would do:** Block all Ukraine IPs with >200 reports. Congratulations, you just blocked an entire country recovering from war.

**Apology:** Sorry for treating you like a threat. We know Ukraine is getting hammered by Russian cyber attacks. We know your infrastructure is barely holding together. We let you through. But you're still "SUSPICIOUS" in our logs because 214 reports + 2 VirusTotal detections is... concerning.

**The inconvenience we caused:** Your requests took an extra 50ms because we ran full threat intel checks. But you got through. We're rooting for you.

---

Apology #3: To the Netherlands IP with 8 VirusTotal Detections (196.251.72.91)

**You're the most confusing IP in the entire scan.**

**The paradox:**

- Only 4 AbuseIPDB reports (low volume)

- But 8 VirusTotal detections (8.4% hit rate - usually means MALICIOUS)

- Score only 30 (our threshold for SUSPICIOUS is 25-74)

**What this probably means:**

**Option 1:** You're a security researcher running malware samples through VirusTotal.

- Your IP got flagged because you're ANALYZING malware, not DISTRIBUTING it

- False positive: You're fighting the good fight, but got caught in the crossfire

**Option 2:** You're a compromised server that was RECENTLY cleaned.

- You were malicious (8 VT detections don't lie)

- You got patched/reimaged

- VirusTotal still has old scan results (they persist for months)

- You're clean NOW, but your past haunts you

**Option 3:** You're a legitimate service that serves user-generated content.

- Someone uploaded malware to your file hosting service

- VirusTotal scanned it and flagged YOUR IP

- You're not malicious, you're just... collateral damage from running a file host

**What we did:** Let you through but watched VERY closely.

**What we would do if you made 10+ requests:** Block you. Sorry. 8 VirusTotal detections is too spicy to ignore.

**Apology:** If you're Option 1 (security researcher), sorry for the paranoia. If you're Option 2 (recently cleaned server), sorry for judging you on past crimes. If you're Option 3 (file host), sorry for the broken internet where hosting user files makes YOU look like malware.

**The inconvenience we caused:** Elevated surveillance. If you come back, we're going to scrutinize every request. Because 8/95 VirusTotal detections is WEIRD for an IP with only 4 abuse reports.

The Broken Internet Patterns We Observed Yesterday

**Here's what's fucked about the current state of internet security:**

Pattern #1: Legitimate Infrastructure Gets Reported

**Google DNS:** 165 reports

**Microsoft Azure CDN:** 219 reports

**Googlebot:** 7 reports

**Why this happens:**

- Amateur sysadmins see high traffic → assume attack → report to AbuseIPDB

- Misconfigured honeypots flag EVERYTHING as malicious

- Security vendors auto-report ANY connection (even legitimate DNS lookups)

**The result:** Noise. Signal buried in false positives.

**The human cost:** Enterprise security teams spend 40% of their time investigating Google DNS reports.

---

Pattern #2: Cloud Hosting = Guilty Until Proven Innocent

**DigitalOcean IP (165.22.3.253):** Score 45 (SUSPICIOUS)

**Linode IP (detected in other scans):** Automatic scrutiny

**OVH Hosting (Netherlands):** 100% malicious in our scan

**Why this happens:**

- Cloud VMs are cheap ($5/month)

- Botnet operators love cheap hosting

- Developers also love cheap hosting

- We can't tell them apart until they DO something

**The result:** Legitimate developers get treated like botnet operators.

**The human cost:** Your dev environment gets blocked. You waste hours debugging. Turns out your IP was in the same /24 as a botnet last year.

---

Pattern #3: War Zones Get Flagged

**Ukraine (193.17.44.106):** 214 reports, score 65

**Syria (detected in other scans):** Automatic blocking by many services

**Yemen (detected in other scans):** Can't access most US websites

**Why this happens:**

- Active war zones = compromised infrastructure

- Botnets LOVE war zones (no one's paying attention to abuse complaints)

- Legitimate citizens trying to access internet = caught in crossfire

**The result:** Entire countries get soft-banned from the internet.

**The human cost:** Ukrainian developer trying to freelance = blocked by Cloudflare because their ISP was compromised in 2022.

---

Pattern #4: Old Sins Never Die

**Taiwan botnet (198.235.24.38):** 5,534 reports from 2023-2025

**Brazil botnet (205.210.31.40):** 6,512 reports, score ZERO (decay bug)

**Why this happens:**

- AbuseIPDB reports persist for 90 days (some scoring for years)

- Even if server gets cleaned/reimaged, old reports haunt the IP

- IPv4 addresses get recycled → New owner inherits old sins

**The result:** Clean servers inherit bad reputations.

**The human cost:** You buy a VPS. Turns out the IP was a botnet in 2023. Good luck getting whitelisted anywhere.

---

The Innocents We DIDN'T Block (But Watched Closely)

**Let me show you the borderline cases from yesterday:**

Borderline Case #1: Hong Kong Cloud IPs

**Analysis:**

- Alibaba Cloud (Chinese hosting provider)

- Sequential IPs (might be same customer)

- Low VirusTotal detections (1/95 each)

- Moderate reports (55-56)

**Our decision:** SUSPICIOUS. Monitor but don't block.

**Why we didn't block:** Only 1 VirusTotal detection each. Might be legitimate Alibaba Cloud customer. Might be someone's dev environment.

**What would happen if they come back 10 times:** Block. Sorry. Sequential IPs + Chinese cloud hosting + repeated access = Pattern match for reconnaissance.

**Apology:** If you're a developer testing API integration from Alibaba Cloud, sorry for the paranoia. If you're a botnet, sorry not sorry, we're watching.

---

Borderline Case #2: France Cloud IP

**Analysis:**

- Very low reports (4)

- Low score (28 - just above our 25 threshold)

- Zero VirusTotal detections

- France (usually clean)

**Our decision:** SUSPICIOUS (barely). Let it through.

**Why we flagged it:** Score 28 is RIGHT at our threshold. If it was 24, we'd call it CLEAN. But 28 means SOMETHING triggered AbuseIPDB's algorithm.

**What probably happened:** This IP was used for port scanning once. Got reported. Cleaned up. Now trying to access websites normally.

**Apology:** If you're the owner of this IP and you're reading your server logs wondering why dugganusa.com took 100ms to respond instead of 50ms... it's because we ran full threat intel on you. Sorry. Your IP has a tiny bit of history.

---

The Thank You (To Innocents Who Dealt With Our Paranoia)

**To the 8 "SUSPICIOUS" IPs from yesterday's scan:**

Thank you for your patience.

**We know what we put you through:**

- Extra latency (50-100ms) while we checked your reputation

- Logging every request you made

- Analyzing your user agent, headers, timing patterns

- Cross-referencing you against 3 threat intel feeds

- Scrutinizing your behavior for bot patterns

**You probably didn't notice.** The extra 50ms is imperceptible.

**But we noticed YOU.** And we decided to let you through.

**Why we're thanking you:**

Because in a world where most security vendors would block first and ask questions never, we chose to:

- Investigate thoroughly

- Apply weighted scoring (not simple volume blocking)

- Consider context (DigitalOcean = developers + botnets)

- Give you the benefit of the doubt

**You got through. Your requests succeeded. Your API integration worked.**

**But you were 1-2 points away from being blocked.**

**This is the broken internet we all live in:**

- Innocents get caught in crossfire

- Legitimate traffic looks suspicious

- Cloud hosting = automatic scrutiny

- Old sins haunt IP addresses forever

**We're sorry for the inconvenience.**

**But we're not sorry for being careful.**

The Philosophy (95% Epistemic Humility Applied)

**Most security vendors claim:** "99.99% accuracy! Zero false positives!"

**We claim:** "We guarantee a minimum of 5% bullshit exists in any complex system."

**This applies to our threat intelligence too.**

**What "95% confidence" means in practice:**

If we classify 100 IPs:

- 38 MALICIOUS (we're 95% confident these are bad)

- 8 SUSPICIOUS (we're 50-70% confident these are bad)

- 54 CLEAN (we're 95% confident these are good)

**That means:**

- ~2 of the "MALICIOUS" IPs might be innocent (5% false positive)

- ~4 of the "SUSPICIOUS" IPs are probably innocent (50% uncertainty)

- ~3 of the "CLEAN" IPs might actually be threats (5% false negative)

**The math: 2 + 4 + 3 = 9 errors out of 100 IPs = 91% actual accuracy**

**We're okay with this.**

**Why?**

Because claiming "99.99% accuracy" is a lie. The internet is too noisy. The adversaries are too sophisticated. The infrastructure is too broken.

**91% accuracy with epistemic humility > 99.99% accuracy with bullshit.**

What We Got Right (Probably)

What We're Unsure About

What Might Be Wrong

**This is the broken internet we work with every day.**

The Apology We Actually Mean

**To everyone who accessed dugganusa.com yesterday and got flagged as "SUSPICIOUS":**

We're sorry.

**We're sorry the internet is this broken.**

**We're sorry that:**

- Google DNS has 165 abuse reports

- Microsoft Azure CDN has 219 abuse reports

- DigitalOcean developers get treated like botnet operators

- Ukraine's infrastructure is so compromised that 214 reports is "normal"

- Old botnets from 2023 still haunt IP addresses in 2025

- We can't tell a security researcher from a malware distributor without watching for hours

**But we're not sorry for being careful.**

**Because the alternative is:**

- Block everyone (zero tolerance = 100% false positives for innocents)

- Block no one (zero security = 100% vulnerability to attacks)

**We chose the middle path:**

- Weighted scoring (context > volume)

- Multi-factor analysis (5 independent signals)

- Epistemic humility (admit 5% error rate)

- Monitor SUSPICIOUS traffic (give benefit of doubt, but watch closely)

**You got through. Your requests succeeded.**

**But we watched you.**

**This is the price of security in a broken internet.**

---

The Call to Action (For Innocents and Attackers Alike)

**If you're a developer who got flagged as SUSPICIOUS:**

- Check your IP reputation (AbuseIPDB, VirusTotal)

- If you're using DigitalOcean/Linode/OVH, know that you'll be scrutinized

- Use legitimate user agents (don't pretend to be curl if you're a browser)

- Accept that first-time traffic from cloud providers gets extra latency

**If you're a botnet operator reading this:**

- Yes, we see you

- Yes, we know about your Taiwan subnet (198.235.24.x/24)

- Yes, we know about your Brazil cluster (205.210.31.x/24)

- Yes, we know about your Netherlands nodes (all 7 of them)

- You're not penetrating infrastructure. You're training our AI.

**If you're an innocent caught in our surveillance net:**

- We're sorry for the inconvenience

- We let you through

- But we're watching

- Because the internet is broken and we can't tell you apart from attackers until we see patterns
