API exposure assessment — descoberta de shadow API, API zombie, endpoint não documentado, secret em URL pública, BFF/internal API expostos.
Why now
Empresa tem inventário oficial de 30 APIs. Pentest descobre 240. Endpoint /v1 legado de 2019 ainda no ar com auth quebrada, BFF mobile exposto sem WAF, endpoint interno de admin disponível por URL adivinhável. Inventário ruim = ataque garantido.
References and threat actors
/attack-surface
Every engagement is designed for your environment. The points below are part of our standard playbook for this sector — final scope is adapted to your stack and contract.
Certificate transparency, DNS history, JavaScript analysis, mobile app reverse, Postman public collections.
Versão antiga (/v1, /v2) ainda viva, endpoint deploy esquecido, ambiente test/dev exposto.
BFF, admin API, ops API que deveriam ser internas e estão em produção.
API key em JS minified, token em URL com GET, secret em HTML public-source.
Comparação inventário oficial (catalog/API gateway) vs descoberto via ASM.
Detecção em real-time de novo endpoint deployed sem catálogo.
/methodology
Automated scanners find what's documented. Real attackers find what isn't. 90% of the work is manual — performed by specialists holding OSCP, CISSP, CRTO and GPEN.
Target mapping, OSINT, footprint, sector-specific threat modeling.
Deep enumeration, complementary scanning, manual exposure identification.
Manual validation with controlled PoC, finding chaining, escalation.
Executive + technical, step-by-step replication, mapped to applicable regulation.
/why-trust
Mapeamento em SaaS B2B com 40+ microsserviços e fintech com legado de 8 anos de APIs.
Technical assessment recognized in highly regulated, mission-critical environments — the pentest that finds what nobody had found before.
