Detect Affiliate Link Hijacking & Commission Theft
Free scanner to detect affiliate link hijacking, stolen tracking IDs, modified referral codes, and malicious redirects stealing your commissions.
Silent Revenue Theft
Affiliate link hijacking is when hackers modify your affiliate links to replace your tracking ID with theirs. You send traffic, they get paid. Most victims don't realize they're losing commissions until they notice unexplained revenue drops.
Average loss: Affiliate marketers lose $500-$5,000/month to link hijacking before detecting it. Some lose years of accumulated commissions.
How Affiliate Link Hijacking Works
🔀 Direct Link Replacement
Hackers modify your affiliate links in the database or theme files, replacing your affiliate ID with theirs.
Example:
✓ Your Original Link:
amazon.com/product?tag=yourID-20
✗ Hijacked Link:
amazon.com/product?tag=hackerID-20
🎯 JavaScript Redirect Injection
Malicious JavaScript intercepts clicks on your affiliate links and redirects through the hacker's tracking URL first.
What Our Scanner Detects:
- ✓ Click event listeners on affiliate links
- ✓ window.location modifications
- ✓ Obfuscated redirect code
- ✓ External script injections
🔗 Cookie Stuffing
Malware sets affiliate cookies on visitor browsers before they click your links, overriding your referral credit.
Detection Indicators:
- ✓ Suspicious cookie-setting JavaScript
- ✓ Hidden iframes from affiliate networks
- ✓ Base64-encoded cookie manipulation
🌐 Plugin/Theme Backdoors
Nulled plugins or themes with built-in code that automatically hijacks all affiliate links site-wide.
Common Targets:
- ✓ Amazon Associates links
- ✓ ClickBank affiliate IDs
- ✓ ShareASale tracking codes
- ✓ Commission Junction links

Real-World Case Study
Tech Review Blog - $18,000 in Lost Commissions
Industry: Technology Reviews | Platform: WordPress | Traffic: 100,000/month
The Problem:
A tech blogger noticed Amazon Associates commissions dropped from $6,000/month to $500/month over 3 months, despite traffic increasing by 20%. Analytics showed affiliate link clicks were normal.
What Our Scanner Found:
- JavaScript redirect injected in footer.php
- All Amazon links redirecting through hacker's tracking domain first
- Cookie-stuffing code setting hacker's affiliate ID before user clicks
- Obfuscated code in nulled "WP Affiliate Manager" plugin
- Database entries: 847 affiliate links modified with wrong tracking ID
Root Cause:
Blogger installed a "free" premium affiliate plugin from a torrent site. The plugin contained pre-installed malware that hijacked all Amazon, ClickBank, and ShareASale links.
The Impact:
- $18,000 in lost commissions over 3 months
- Hacker earned estimated $15,000+ from stolen traffic
- 2 weeks to identify and fix all hijacked links
- Lost trust with audience (some noticed wrong affiliate IDs)
✅ How It Was Fixed:
- Deleted nulled plugin, installed legitimate version
- Ran database search/replace to restore correct affiliate IDs
- Removed malicious JavaScript from theme files
- Implemented weekly scans with our tool
- Set up affiliate link monitoring alerts
Result: Commissions returned to $6,000/month within 2 weeks of cleanup.
💡 Key Lesson: The blogger lost 3 months of income ($18,000) because they used a nulled plugin to save $47. Never use pirated plugins or themes - the cost is always higher than the savings.
