Why Dependency Security Is a Bigger Problem Than Hackers

Modern applications don’t fail because of hackers.

They fail because they trust too much code they didn’t write.

The Hidden Attack Surface

A simple web app might have:

• 10 direct dependencies
• 300+ transitive dependencies

Each dependency:

• Executes code
• Has maintainer access
• Can be compromised

Common Dependency Attacks

Typosquatting

expresss instead of express

Dependency Confusion

Public package overrides private internal one

Maintainer Compromise

Trusted package → malicious update

---

Why This Is Hard to Defend

• Dependencies auto-update
• Transitive dependencies are invisible
• Audits are often ignored
• Security warnings are dismissed as “noise”

Attackers exploit trust, not vulnerabilities.

---

Real Security Measures

• Lockfile enforcement
• Dependency pinning
• Minimal dependency philosophy
• Runtime monitoring
• Supply-chain audits

Security starts before runtime.

Cybersecurity Perspective

Every dependency is:

An external actor inside your system

Treat it accordingly.

Final Thought

The biggest risk in your app
isn’t who attacks it —

it’s what you already installed.
