Offensive security assessments
Brute Force Attack
An attacker systematically tries many credentials, tokens, or values until one works. It succeeds when an endpoint lacks rate limiting, lockout, or sufficient secret entropy.
How we test it
Our operators follow a structured checklist for this topic, adapted to your API surface and authentication model.
Testing approach
- Structured validation of Brute Force Attack during scoped assessment.
- Evidence captured with reproducible steps for your engineering team.
What we look for
- Misconfigurations and control gaps related to Brute Force Attack.
- Exploitable paths that could affect confidentiality, integrity, or availability.

| Arbitrary Cookie Flags | Cookies that hold session or sensitive data are set without the proper security flags (Secure, HttpOnly, SameSite). This lets cookies travel over cleartext, be read by JavaScript, or be sent on cross-site requests, enabling theft and CSRF. |
| Back Button Attack | After a user logs out (or on a shared device), pressing the browser Back button or reopening cached pages reveals sensitive data or restores an authenticated view. This happens when the server lets responses be cached and does not fully invalidate the session. |
| Broken Authentication | Flaws in how an application confirms a user's identity, letting attackers compromise passwords, tokens, or sessions and assume other users' identities. It is one of the highest-impact web risks (OWASP Top 10: Identification and Authentication Failures). |
| Captcha Bypass | A CAPTCHA is meant to block automated requests, but flawed implementation lets attackers skip or solve it programmatically. Bypassing it re-enables brute force, spam, and other automation the control was meant to stop. |
