Engagement
Kickoff Time
We test the way attackers work, so your team can fix problems first.
We test what attackers can see, then we go deeper.
Every digital product exposes an attack surface. We map it, understand it, and test it like an adversary would.
VULNERABILITY ASSESSMENT
VECTOR // 06Scanning validated by hand: misconfigurations, missing patches and exposed services, ranked by risk.
Finding vulnerabilities
is only the beginning.
We go beyond superficial automated detection. Our offensive team connects isolated flaws into verifiable exploit chains that prove real business impact.
Confidential by default
We don't name our clients or publish their results. Here is what you can check instead: how we handle your data, and what you receive at the end.
An NDA comes first
We sign a mutual NDA, or work under yours, before you share scope, credentials or architecture.
Your findings stay yours
Reports, proof-of-concepts and test credentials are classified as strictly confidential and never reused.
Every finding is verified by hand
No unvalidated scanner output. Each issue in your report has been reproduced by one of our testers.
A clean exit
When the engagement ends, we purge test accounts, credentials and working files. Written confirmation on request.
Broken object-level authorization in the invoices API
- Affected asset
- https://.com/api/v2/invoices/{id}
- Impact
- Any signed-in user could read other customers' invoices, including billing addresses and payment references, by changing the invoice ID.
- Proof of concept
GET /api/v2/invoices/ Authorization: Bearer HTTP/1.1 200 OK another customer's invoice returned
- Fix
- Check that the invoice belongs to the requesting account on every call to this endpoint.
An illustrative example of how findings are written up. Client names, hosts and data are always redacted outside the engagement.
