How the 1885-O Morgan ‘Belly Button’ Teaches Us to Build Smarter Cybersecurity Tools

Forge Stronger Cyber Defenses by Learning From Rare Coin Flaws

Here’s a truth I’ve learned both as a developer and coin collector: The best security tools work like a numismatist’s loupe. That peculiar “belly button” dent on 1885-O Morgan dollars? It’s more than a minting flaw – it’s a masterclass in spotting critical anomalies. Just as coin experts authenticate specimens by studying tiny die variations, we can engineer cybersecurity tools that detect digital fingerprints of compromise. Let’s explore how this antique silver dollar teaches us to build sharper threat detection.

1. Spotting Digital Die Flaws: The Art of Cyber Anomaly Detection

Training Your Hacker’s Eye

When I first examined a genuine belly button Morgan, I needed three things: good lighting, magnification, and reference materials. Cybersecurity demands similar rigor. Modern threat detection relies on:

• Behavioral tracking that notices when users act out of pattern
• Signature detection for known malware like coin experts spot familiar die cracks
• Machine learning that flags statistical oddities as instinctively as a collector spots counterfeit patina

“Much like measuring a belly button’s depth distinguishes VAM-24 Morgans, tracking AWS API call sequences reveals intruders hiding in cloud noise.” – From my dog-eared Security Field Notes

Building Your Digital VAM Catalog

Serious collectors use sites like VAMworld to catalog die varieties. For security teams, a well-tuned SIEM serves the same purpose. Consider this real-world example – a detection rule that spots malicious PowerShell activity like a collector identifying a key coin feature:


detection:
selection:
Channel: 'Microsoft-Windows-PowerShell/Operational'
EventID: 4104
ScriptBlockText|contains:
- 'New-Object System.Net.Sockets.TCPClient'
- 'Invoke-Expression'
condition: selection


2. Ethical Hacking: Finding Vulnerabilities Before Attackers Do

The Coin Collector’s Testing Method

Notice how the belly button variety always appears with specific die cracks? That consistent flaw pattern mirrors how penetration testers work:

1. Map your attack surfaces like a numismatist examines coin fields
2. Identify recurring weaknesses (your system’s “die cracks”)
3. Chain vulnerabilities together like connecting minting flaws

Real-World Coin Lesson: Last quarter, we found 80% of client XSS flaws occurred in forms without output encoding – a systemic “die crack” we now automatically flag during code reviews.

Crafting Custom Security Tools

Just as collectors use specialized magnifiers, we build custom scanners. This Python script checks Jenkins instances for unpatched vulnerabilities – think of it as a digital coin microscope:


import requests
from bs4 import BeautifulSoup

def check_jenkins_vulns(url):
try:
response = requests.get(f"{url}/manage")
if "Dashboard" in response.text:
soup = BeautifulSoup(response.text, 'html.parser')
version = soup.find('div', {'class': 'jenkins-version'}).text.strip()
if compare_versions(version, '2.401') < 0: return f"Vulnerable Jenkins {version} - CVE-2023-XXXX" except Exception as e: return f"Scan error: {str(e)}"

3. Coding Without Security 'Belly Buttons'

Preventing Digital Minting Flaws

That Morgan dollar's belly button resulted from improper die preparation. Our code suffers similar flaws when rushed:

• Input Validation: Like ensuring proper metal flow into dies
• Memory Management: Preventing overflow cracks in your code's structure
• Configuration Checks: The digital equivalent of die alignment

Pro Tip: Implement pre-commit hooks that scan for 15 critical patterns (SQLi, exposed secrets, etc.) - your code's die inspection phase.

Striking Secure Code

This Node.js middleware acts like a coin press operator, applying proper validation pressure to user inputs:


const { body, validationResult } = require('express-validator');

app.post('/user',
body('email').isEmail().normalizeEmail(),
body('password').isLength({ min: 12 }).matches(/[!@#$%^&*]/),
(req, res) => {
const errors = validationResult(req);
if (!errors.isEmpty()) {
return res.status(400).json({ errors: errors.array() });
}
// Proceed with secure user creation
}
);


4. Threat Intelligence: Your Cybersecurity VAMworld

The Collector's Approach to Defense

Coin communities meticulously catalog variations. We need equal rigor in threat intelligence:

Building Collector's Reflexes in Your Team

Just as experts instantly recognize a belly button Morgan, train your SOC to spot threats through:

1. Create 20 critical scenario playbooks (credential dumping, lateral movement)
2. Run weekly threat hunts using Sysmon logs mapped to ATT&CK
3. Automate IOC ingestion from trusted sources

Striking Balance: Perfect Imperfections

That 1885-O Morgan teaches a vital lesson: Flaws become powerful identifiers when properly understood. Our cybersecurity mission mirrors numismatics:

• Build detection tools with a collector's obsessive eye
• Pen test like we're examining coin surfaces under magnification
• Code with the precision of master die engravers

Next time you examine security logs, channel your inner numismatist. Look for those digital belly buttons - the subtle imperfections that reveal everything. Because in both coin collecting and cybersecurity, mastery lies not in finding perfection, but in understanding flaws better than attackers do.
