Why now

The real pain

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.

API Exposure

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.

01

Discovery via ASM

Certificate transparency, DNS history, JavaScript analysis, mobile app reverse, Postman public collections.

02

Shadow API e zombie API

Versão antiga (/v1, /v2) ainda viva, endpoint deploy esquecido, ambiente test/dev exposto.

03

Internal API expostos

BFF, admin API, ops API que deveriam ser internas e estão em produção.

04

Secrets em URL/JS público

API key em JS minified, token em URL com GET, secret em HTML public-source.

05

API inventory vs realidade

Comparação inventário oficial (catalog/API gateway) vs descoberto via ASM.

06

Monitoring contínuo

Detecção em real-time de novo endpoint deployed sem catálogo.

/methodology

Genuinely manual pentest

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.

01 · Reconnaissance

Target mapping, OSINT, footprint, sector-specific threat modeling.

02 · Discovery

Deep enumeration, complementary scanning, manual exposure identification.

03 · Exploitation

Manual validation with controlled PoC, finding chaining, escalation.

04 · Report

Executive + technical, step-by-step replication, mapped to applicable regulation.
