What we find

We're new. We won't pretend otherwise.

No borrowed logos, no invented case studies, no numbers we can't stand behind. What we can show you is the depth: the classes of finding we hunt, written exactly the way our reports read.

The bugs we hunt.

Root cause, impact and fix, mapped to the standard your auditor will ask about. Every report finding follows this shape.

WebCritical

JWT algorithm confusion leads to cross-tenant account takeover

Root
An RS256 verifier that also accepts HS256 lets an attacker sign tokens with the public key.
Impact
Log in as any user, in any tenant.
Fix
Pin the algorithm; separate verification keys by type.

OWASP A07 · ASVS V3

APIHigh

Broken object-level authorisation at scale

Root
Sequential IDs plus a missing ownership check expose every record through one endpoint.
Impact
Bulk disclosure across the customer base.
Fix
Per-object authorisation on every read; non-enumerable identifiers.

OWASP API1:2023

AIHigh

Indirect prompt injection turns an agent into an exfiltration channel

Root
A poisoned document in the retrieval corpus rewrites the agent's instructions; a tool call ships internal context out.
Impact
Silent data loss through a “trusted” workflow.
Fix
Separate content from instructions; allow-list tool calls; control egress.

OWASP LLM01 · MITRE ATLAS

NetworkCritical

From the guest network to Domain Admin

Root
LLMNR poisoning, relayed credentials and Kerberoasting reach an over-privileged service account.
Impact
Full domain compromise from an unauthenticated start.
Fix
Disable LLMNR/NBT-NS, enforce SMB signing, tier admin accounts.

MITRE ATT&CK T1557 · T1558

CloudHigh

Cross-tenant escalation through a stale guest identity

Root
An external guest keeps a role assignment after offboarding; a consented app inherits it.
Impact
Lateral movement across the tenant boundary.
Fix
Guest lifecycle governance and periodic access review.

CIS Microsoft 365 · ISO 27001 A.5.18

LogicHigh

A race condition turns a one-time coupon into infinite credit

Root
Concurrent redemptions bypass a check-then-act balance update.
Impact
Direct financial loss that no CVE scanner sees.
Fix
Atomic decrement, idempotency keys, row-level locking.
