Marketing Infrastructure Security
Marketing Channel Security Audit
Your paid advertising stack is an attack surface. We audit the conversion tracking, GTM containers, ad platform credentials, and marketing plugins that standard security assessments miss — because they require understanding both the marketing tool and the attack vector.
The Problem
Marketing teams configure pixels, server-side conversion APIs, and tag managers to optimize ROAS. Security teams audit servers, firewalls, and access controls. Neither team audits the overlap — and that overlap is where the vulnerabilities live.
Conversion forging, credential exposure, tag injection, and account takeover are four documented attack categories affecting paid advertising infrastructure. Some are actively exploited in the wild. Others are proven exploitable through published CVEs. All are fixable — but only if someone audits them.
Four Attack Surfaces We Audit
The four attack categories we audit — each invisible to standard security assessments.
1. Conversion Forging
Unauthenticated endpoints in WordPress tracking plugins allow attackers to submit fake purchase events through your stored API credentials. This poisons automated bidding and inflates ROAS.
- AJAX endpoint authentication checks
- Server-side CAPI validation logic
- Conversion event deduplication
- WooCommerce plugin vulnerability scan
2. Credential Exposure
Ad platform API tokens, payment gateway keys, and access tokens can leak through client-side HTML, verbose error responses, or misconfigured plugins.
- Client-side source scan for exposed tokens
- Error response analysis for credential leaks
- Plugin settings exposure review
- MCP server configuration audit
3. Tag & Pixel Injection
GTM containers, Meta Pixel, and TikTok Pixel plugins introduce executable JavaScript into every page. If compromised, they become skimmer delivery mechanisms invisible to CSP and WAF.
- GTM container ID inventory & validation
- CSP policy review for tag manager gaps
- Pixel plugin XSS vulnerability scan
- Third-party script chain analysis
4. Account Takeover Exposure
Ad account access controls, dormant user permissions, and agency portfolio configurations are the most common entry points for account hijacking.
- Meta Business Manager access audit
- Google Ads user permission review
- Dormant/former-employee access scan
- MFA and session security assessment
How It Works
Our four-step audit methodology — from scoping your marketing stack to delivering a written remediation plan.
Scope Your Marketing Stack
We inventory your ad platforms, conversion tracking integrations, GTM containers, marketing plugins, and agency access points. You tell us what you run; we map the attack surface.
External & Internal Scan
We run the external scan from a visitor's perspective: source code analysis for exposed tokens, GTM container enumeration, third-party script chain mapping, and conversion endpoint testing. With admin access, we also review plugin configurations, API key storage, and user permissions.
Analyze & Classify
Every finding is classified by attack category, exploitability, and business impact. We cross-reference against published CVEs and active campaigns — not just theoretical risk.
Deliver Report & Remediation Plan
You receive a written report with findings, risk ratings, and step-by-step remediation for each issue. We include specific config changes, plugin recommendations, and CSP rules — not generic advice.
What You Get
The audit outcome — same marketing stack, before and after remediation.
- Complete marketing stack inventory (platforms, plugins, containers, integrations)
- GTM container audit — container ID validation, unauthorized container detection
- Conversion endpoint security assessment (AJAX auth, CAPI validation, nonce exposure)
- Client-side credential exposure scan (API tokens, payment keys, access tokens in source)
- CSP policy gap analysis for marketing domains (googletagmanager.com, connect.facebook.net, etc.)
- Ad platform access control audit (Meta BM, Google Ads, analytics properties)
- Dormant user and former-employee access report
- Prioritized findings: Critical, High, Medium, Low
- Step-by-step remediation for every finding (config changes, plugin swaps, CSP rules)
- Cross-reference against active CVEs and known Magecart campaigns
