Community Research Led to Stronger Protection

Following yesterday’s axios supply chain attack announcement, we’ve implemented an additional protective layer based on security community recommendations.

After publishing our axios safety verification yesterday, our team researched additional defenses recommended by the security community on Twitter/X, including experts from Socket.dev (@feross), npm security researchers, and the broader open-source community.

Result: We’ve implemented time-delay protection in our .npmrc configuration that would have automatically blocked the axios attack.

What We Added

.npmrc Supply Chain Protection

# Supply chain attack protection (added April 1, 2026)
min-release-age=7
ignore-scripts=true

These two settings create a critical defensive layer:

1. min-release-age=7 - Week-Old Package Rule

What it does: Blocks npm from installing packages newer than 7 days old.

Why it matters: Most supply chain attacks are discovered and removed within 48-72 hours. By waiting 7 days before adopting new package versions, we avoid the critical window when compromised packages are live on npm.

Real-world impact:

  • axios 1.14.0 (compromised March 27) → Would be blocked until April 3
  • axios 1.14.1 (compromised March 31) → Would be blocked until April 7
  • separadordeinfocc 1.0.0 (LofyGang attack, April 1) → Would be blocked until April 8

The axios attack would have been automatically prevented.

2. ignore-scripts=true - No Install Scripts

What it does: Prevents npm packages from running install/postinstall scripts during npm install.

Why it matters: The axios supply chain attack used postinstall scripts to:

  • Steal .env files with API keys and secrets
  • Exfiltrate credentials to remote servers (sfrclak.com, callnrwise.com)
  • Connect to WebSocket C2 channels for remote control

Real-world impact: Even if a compromised package made it past the 7-day delay, ignore-scripts=true would have prevented the credential theft and data exfiltration.

Defense in Depth

This .npmrc protection complements our existing security layers:

Layer 1: Socket.dev Integration (March 31)

  • Automated supply chain vulnerability scanning
  • GitHub Actions security audit daily at 9 AM UTC
  • Real-time alerts for typosquatting and malicious packages
  • CLI tool integration for local development

Layer 2: .npmrc Time-Delay Protection (April 1) ← NEW

  • min-release-age=7: Automatic 7-day waiting period for new packages
  • ignore-scripts=true: Block install scripts from all packages
  • Zero-configuration protection (works automatically)

Layer 3: Package Lock Discipline

  • Conservative update schedule (not chasing “latest”)
  • Manual review of dependency changes
  • Version pinning for critical dependencies

Layer 4: GitHub Advanced Security

  • Dependabot vulnerability alerts
  • Secret scanning for API keys/tokens
  • Code scanning for security issues
  • 2FA enforcement for all maintainers

Why This Matters for Our Community

You Don’t Need to Be a Security Expert

These protections work automatically in the background:

  • No configuration required from users
  • No action needed during attacks
  • Transparent protection that doesn’t slow development

Lessons from Real Attacks

March 27-31, 2026 - axios Compromise:

  • 3 malicious versions published over 4 days
  • Maintainer account takeover (jasonsaayman)
  • Credential theft via postinstall scripts
  • C2 infrastructure (142.11.206.73, 18.231.131.246)
  • Result with our protection: Would have been auto-blocked

April 1, 2026 - LofyGang Attack (separadordeinfocc):

  • Published same day as our .npmrc hardening
  • WebSocket C2 channel (ws://18.231.131.246:80)
  • Result with our protection: Would have been auto-blocked

Community-Powered Security

This protection was discovered through:

  • Twitter/X security community discussions
  • Socket.dev team recommendations (@feross)
  • npm security researcher insights (@yuvadam)
  • Open-source security best practices

When the community shares knowledge, everyone wins.

Why Your Data Is Safe: Local-First Architecture

Beyond protecting our build process, we’ve designed 3mpwrApp so your personal data is safe even in worst-case scenarios.

Your Data Stays on YOUR Device 🔒

Default behavior: Everything is local-first

  1. Device Storage by Default:
    • All user data starts on YOUR device (phone, tablet, computer)
    • Uses AsyncStorage (mobile) or localStorage (web)
    • AES-256 encryption for sensitive data
    • Auth tokens stored in platform-native Keychain (iOS) / KeyStore (Android)
  2. What’s Stored Locally:
    • Your cases and evidence
    • Wellness data (mood, energy, symptoms)
    • Documents and uploaded files
    • Personal notes and reminders
    • Community chat messages (cached)
    • All settings and preferences
  3. Zero Cloud Requirement:
    • Guest mode: 100% local, no cloud sync
    • Works offline with full functionality
    • No data leaves your device unless you choose

BYOC: Bring Your Own Cloud ☁️

You control where your data lives and who can access it.

Three Data Storage Modes:

Mode Where Data Lives Who Controls It Best For
Guest Mode Your device only You (100%) Maximum privacy, no cross-device sync
Default Mode Your device + optional Firebase sync Shared (encrypted) Convenience, multi-device access
BYOC Mode Your device + YOUR cloud storage You (100%) Data sovereignty + cloud backup

How BYOC Works:

Step 1: You Connect Your Cloud

Settings → Privacy → BYOC (Bring Your Own Cloud)
→ Choose: Google Drive, Dropbox, OneDrive, iCloud
→ Authenticate with YOUR account (not ours)

Step 2: Encrypted Backups to YOUR Cloud

  • App creates encrypted backup files
  • Syncs to YOUR Google Drive / Dropbox / etc.
  • Uses YOUR authentication tokens
  • 3mpwrApp never sees your cloud credentials

Step 3: You Hold the Encryption Keys

  • Keys stored on YOUR device
  • We can’t decrypt your backups (only you can)
  • Delete the app? Your data stays in YOUR cloud
  • Reinstall? Restore from YOUR cloud

BYOC Protection Against Supply Chain Attacks:

Even if a compromised package made it into our app:

✅ Your data is encrypted - Attacker can’t read it without your device’s encryption key
✅ Keys never leave your device - ignore-scripts=true blocks malicious install scripts from stealing keys
✅ Your cloud, your control - BYOC mode means attacker can’t access YOUR Google Drive / Dropbox
✅ No central database to breach - Data is distributed across thousands of user-controlled cloud accounts
✅ Authentication isolated - Your cloud storage uses YOUR authentication, not app credentials

This is why local-first + BYOC matters:

In the axios attack, compromised packages stole .env files and credentials from developer machines. But user data stored on user devices with user-controlled encryption? Untouchable.

Real-World Example: axios Attack Containment

March 27-31, 2026 - What axios compromise COULD have done:

  • ❌ Steal developer secrets (API keys, Firebase credentials) - BLOCKED by .npmrc
  • ❌ Exfiltrate user database from centralized server - NO CENTRALIZED DATABASE
  • ❌ Decrypt user data from cloud backups - KEYS ON USER DEVICES
  • ❌ Access user’s Google Drive / Dropbox - USER CONTROLS AUTH

What actually happened:

  • ✅ We detected the compromise before any npm operations
  • ✅ User data remained local and encrypted on their devices
  • ✅ BYOC users’ data stayed in their personal cloud accounts
  • ✅ Zero user data exposure

Data Sovereignty = Security

Your data architecture protects you three ways:

  1. Local-First: Data doesn’t transit through our servers by default
  2. User-Controlled Cloud: BYOC puts you in charge of backups
  3. Encryption: AES-256 means compromised app can’t read your data

Combined with .npmrc protection:

  • Supply chain attacks blocked before they reach production
  • Even if one got through, user data architecture limits damage
  • Multiple independent layers (defense in depth)

This is industry-leading privacy for disability rights / injury support apps.

Technical Details

How min-release-age Works

# Before (vulnerable):
$ npm install axios@latest
# ❌ Installs axios 1.14.1 (compromised, 1 day old)

# After (protected):
$ npm install axios@latest
# ✅ npm ERR! Package axios@1.14.1 is too new (1 day < 7 days)
# ✅ Falls back to axios 1.13.6 (safe, 42 days old)

How ignore-scripts Works

# Before (vulnerable):
$ npm install malicious-package
# ❌ Runs postinstall script
# ❌ Steals .env file
# ❌ Sends credentials to attacker

# After (protected):
$ npm install malicious-package
# ✅ Package installed
# ✅ NO scripts executed
# ✅ Credentials safe

When You Need Install Scripts

Some legitimate packages require install scripts (native bindings, binary downloads). For those specific cases:

# Temporarily allow scripts for trusted package:
$ npm install --ignore-scripts=false trusted-package

# Or in package.json for production:
{
  "scripts": {
    "postinstall": "npm rebuild specific-native-package"
  }
}

Default-deny security: Scripts blocked by default, explicitly allowed only when needed.

What This Means for 3mpwrApp

Current Status (as of April 1, 2026):

✅ axios verified safe (1.13.6, installed March 25)
✅ Socket.dev protection active (March 31)
✅ Time-delay protection active (April 1)
✅ Install script blocking active (April 1)
✅ No compromised packages detected
❌ npm operations still paused until axios all-clear (est. April 5-7)

Next Steps:

  1. Monitor axios resolution (daily checks)
  2. Resume npm operations after official all-clear
  3. Install Socket.dev CLI when safe
  4. Activate sfw tool (from @feross/Socket.dev)
  5. Re-enable Dependabot alerts
  6. Document lessons learned

For Other Developers

Implementing This Protection

1. Add to your .npmrc (project or global):

# Supply chain attack protection
min-release-age=7
ignore-scripts=true

2. Commit to your repository:

git add .npmrc
git commit -m "chore: Add supply chain attack protection"

3. Test with a recent package:

# Test min-release-age (should fail for packages <7 days old)
npm install some-brand-new-package

# Test ignore-scripts (should install but skip scripts)
npm install --dry-run

That’s it. No complex configuration, no ongoing maintenance.

Compatibility Notes

  • Compatible with: All npm versions 7.0.0+ (2020)
  • No breaking changes: Existing packages still work
  • Selective override: Use --ignore-scripts=false when needed
  • Team adoption: Works in package-lock.json for consistent behavior

The Bigger Picture: Data Sovereignty + Supply Chain Security

This incident reinforced a fundamental principle: Your data security shouldn’t depend solely on developer tools.

Two-Layer Protection Philosophy:

Layer 1: Prevent Compromises (Supply Chain Security)

  • .npmrc protection blocks malicious packages
  • Socket.dev monitors for threats
  • GitHub Advanced Security scans code
  • Goal: Stop attacks before they reach production

Layer 2: Limit Damage if Prevention Fails (Data Architecture)

  • Local-first storage (data on user devices)
  • BYOC mode (user-controlled cloud)
  • AES-256 encryption (keys on user devices)
  • Goal: Even if app compromised, user data stays safe

Why both matter:

In the axios attack, thousands of developers’ development credentials were stolen because they relied only on Layer 1 thinking. When that failed, they had no Layer 2.

3mpwrApp’s approach: Assume Layer 1 will eventually fail. Design Layer 2 so user data is protected regardless.

For Injured Workers & Persons with Disabilities

Your sensitive data is uniquely valuable and vulnerable:

  • Medical records and disability documentation
  • WSIB/WCB case files and evidence
  • Legal correspondence and strategies
  • Mental health and wellness tracking
  • Financial and benefits information

Traditional cloud apps store all this in centralized databases. One breach = everyone’s data exposed.

3mpwrApp’s architecture:

  • Your data stays on YOUR device
  • Encrypted with keys only YOU hold
  • Optional BYOC puts YOU in control of cloud storage
  • No central database to breach

This is data sovereignty for the disability rights movement.

A Message to Our Community

We’re not just building an app. We’re building a trust relationship.

When you document workplace injuries, track WSIB discrimination, or store evidence of systemic ableism - that’s not just “user data.” That’s your lived experience, your fight for justice, your path to healing.

We designed our security architecture around one question: “What if we get breached tomorrow?”

  • Would your WSIB case evidence be safe? Yes (local-first + BYOC)
  • Could attackers read your medical records? No (encrypted, keys on your device)
  • Would your legal strategy be exposed? No (no central database)
  • Could they access your wellness tracking? No (local storage)

Supply chain protection (.npmrc) reduces risk. Data sovereignty (BYOC) limits damage.

Together, they create resilient security worthy of your trust.

Status: All 3mpwrApp users and data remain completely safe. No action required from beta testers.
