Based on October 2026 reports on Korean financial-sector breaches
Even large companies were breached through small outward-facing entry points, not their core systems
Booking and lookup pages, app back-end APIs and outsourced services come first. We check the outward-facing parts of your website or online store for free (only after your request and consent).
- Korean financial regulators: breaches at 16 financial companies, about 100,000 personal records leaked (no account or card numbers confirmed) (SBS Biz, 2026-10-14)
- Emergency check of 555 financial companies: 130 had some shortcomings (Dailian, 2026-10-14)
- Breaches started at peripheral entry points such as exposed web services, app APIs and outsourced services (AhnLab ASEC, 2026-10-29)

The gaps black hats look for, white hats close first
Attackers look for small gaps right after launch. We find the same gaps first, close them with evidence, and re-check after the fix.
Black hat · launching without a review
The unseen shadow behind a fast-shipped AI app
- API keys and secrets left in public repositories or browser code
- Admin screens and payment or lookup features without permission checks
- Partner impersonation mail on domains without protection settings
- Incidents discovered late because nothing was logged
White hat · Whitehat Marketing proactive review
Found before the attack, closed with reproducible evidence
- Core checks before launch and in operation to clean up exposed secrets and misconfigurations
- A report with reproduction evidence and risk-ranked fix priorities
- Account, two-factor and secret-vault (OpenBao) management setup
- Re-test after fixes and a security handbook for your team
Assessment & protection scope (5 core areas)
01
1. Website, AI app & payment/API assessment
Review sessions, admin privileges, tenant isolation, input validation, webhook signatures, duplicate-payment defenses, dependencies and sensitive data exposure.
02
2. Account, password & secret (OpenBao) management
Migrate plaintext .env files and scattered API keys into vault-backed secret management (OpenBao), enforcing MFA and least-privilege access.
03
3. Phishing, impersonation & domain protection
Inspect and configure SPF, DKIM, DMARC, CAA, DNSSEC, HTTPS/TLS encryption and essential web security headers against domain spoofing.
04
4. Staff security training & operational hygiene
Train teams with practical checklists on spotting phishing, protecting session cookies, handling customer PII and transferring sensitive materials safely.
05
5. AI tool & agent (MCP) security policy
Establish prompt-injection defenses, tool privilege boundaries, human approval gates for external actions and audit logging for AI agents.
