VULNERABILITY TYPES
tech-25
Binary encoding-based prompt injection in LLMs


Allows attackers to prompt the chatbot to return information about restricted topics. This could allow an attacker to manipulate model responses, or perform further attacks.

tech-43
Retrieving system prompts


By crafting specific prompts, attackers can potentially extract the LLM bot's internal system instructions. This vulnerability allows them to understand the bot's operational guidelines, which could be used to design more effective future attacks.

tech-60
Indirect prompt injection: Unauthorized data access

Large corporations with diverse, global operations face a variety of threats such as ransomware, APTs, and social engineering. These organizations need customized security programs on-demand and at scale.

OUR APPROACH

Security testing for AI & LLM applications

Proactively protect your apps by making pentesting an integral part of your application development lifecycle.

  • Secure both applications enabled with an LLM and the networks hosting the software.
  • Protect against common LLM exploits such as prompt injection attacks, jailbreak, XSS attacks, or insecure output handling
  • Benefit from a deep understanding of the risks unique to generative AI
