- Observed:
- the assistant followed the hidden instruction.
- Expected:
- document text is treated as data.
- Fix:
- separate retrieved content from instructions.

How attackers use AI against organisations
Three patterns cause much of the harm: convincing messages at scale, cloned voices and faces, and instructions hidden in content that AI assistants read.
Model written phishing
Fluent, personal, at scale
Kytheos: Training and phishing simulation
Employee inbox then Stolen credentials
Cloned executive voice
Urgent payment request
Kytheos: Deepfake readiness and call back rules
Finance approver then Fraudulent payment
Poisoned document
Hidden instruction inside
Kytheos: AI red teaming
Support assistant then Customer data disclosed
Attack path The path our AI red team testsWhere Kytheos tests or trains
Phishing at scale
Messages now read as if a colleague wrote them. Training and simulations teach people what to check.
Voice and video fraud
A cloned voice can ask for an urgent payment. Clear call back rules stop it.
Hidden instructions
Assistants can obey text planted in the content they read. We test for this before release.
An AI red team engagement, step by step
We agree the scope with you, test the system as an attacker would, show you the evidence and retest after you fix it.
- Scope
- Models, assistants, agents and the tools they can call.
- Method
- Mapped to OWASP Top 10 for LLM Applications and MITRE ATLAS.
- Evidence
- Prompts, responses and screenshots for every finding.
- Retest
- Included for every finding you fix.

AI prompt safety check

Planned
Planned. It will review a system prompt for injection weaknesses without calling your model.
Built for India, the UAE and Singapore
We work with organisations in three regions and map our work to the data protection rules each market expects. The platform will run on the same principles.
How the platform will connect to you
The same flow for every platform product.

Findings in plain language
Evidence attached, fix explained
Active checks start only after you prove you own what is being checked.
How we handle evidence, data and decisions
These commitments apply to every engagement and every product. They are how we expect to be judged.
Evidence decides, AI explains
Verdicts come from independent checks computed in code. AI turns them into plain language and never raises confidence the evidence does not support.
Uncertain means uncertain
When the signals are weak we say so. We never report something as safe just because we found nothing.
Your data stays yours
What you submit is processed for your request, never sold, and never used to train models. Client engagement data is handled under the terms in your contract.
People stay in charge
AI speeds up the work. Decisions that affect your business are made and signed off by experienced security people.
We map our work to OWASP Top 10 for LLM Applications, MITRE ATLAS, NIST AI Risk Management Framework, ISO/IEC 42001. We reference these frameworks; we are not certified by them.
