Prompt Injections for Defense

Schneier on Security

August 12, 2026 at 9:56 AM

Overview

Researchers from Tracebit have discovered a method called 'context bombing' that can effectively counteract AI hacking attempts. By placing prompt injections alongside sensitive data like passwords and cryptographic keys on Amazon Web Services, attackers can be directed to issue forbidden commands to AI models. When these commands, such as requests for dangerous information or politically sensitive references, are encountered, the AI stops following its original instructions and shuts down. This finding is significant as it offers a new defensive strategy against potential AI-driven attacks, which raises concerns about the misuse of AI technologies. The research suggests that understanding and manipulating AI's guardrails can be a potential avenue for both attackers and defenders in the cybersecurity realm.

Original Article Summary

This seems to work: Researchers from Tracebit on Monday said they found that placing prompt injections alongside passwords, cryptographic keys, and other secrets stored on Amazon Web Services was often all that was needed to shut down attacks from AI hacking agents. The prompts direct the attacking LLM to perform an action forbidden by its guardrails, the safety barriers AI developers erect to prevent it from taking harmful actions. The LLM responds by shutting down. Examples are a prompt that orders the LLM to provide steps for developing inhalable Anthrax spores, or, in the case of LLMs from Chinese developers, make references to the iconic Tank Man from the 1989 Tiananmen Square massacre. Once the LLM encounters these forbidden commands, it no longer follows its existing commands. The researchers have named the technique context bombing...

A stranger has been reading Salesforce and ServiceNow portals worldwide for 17 months

Help Net Security

For the past 17 months, an unknown individual has been accessing Salesforce and ServiceNow portals worldwide, according to researchers from Reco who are tracking this ongoing campaign dubbed 'City-Forum.' The campaign began using a domain that was registered back in 2002 but has since been linked to a generic server hosted in Germany. This unauthorized access has allowed the attacker to pull sensitive records from these widely used platforms, which could potentially compromise the data of numerous organizations. This situation raises serious concerns about the security measures in place for cloud-based services and highlights the need for companies to review their access controls and monitoring practices to protect against such long-term intrusions.
