The Extended Brief
“Keep going, bro. You’ve got this!” A data-driven look at how adversaries are weaponizing AI

Talos's analysis of criminals' abandoned chat logs shows AI guardrails rarely stop misuse — and gives defenders a new forensic trail.
Key points
- Talos found AI guardrails offered little protection, with most actors getting models to comply without sophisticated techniques or encoding.
- Adversaries' prompt logs, left on endpoints by tools like Claude Code, CodeX, Cursor, and Gemini, enabled Talos's analysis.
- Talos grouped observed abuse into three categories: malicious code development, scaling criminal campaigns, and vulnerability research.
- An actor's pre-existing skill largely determines what they can accomplish with AI, Talos observed.
- Novices built malicious capabilities with limited success, while advanced users produced sophisticated, complex outputs.
From the source
“Based on the evidence Talos gathered, guardrails did not provide much protection, with most actors able to convince the models to comply despite the lack of sophisticated techniques or encoding.”
“The pre-existing skill of the actor has a large impact on what they can accomplish with AI.”
“Leveraging cloud-based AI models leaves behind a variety of artifacts, most notably a prompt log.”
“These logs can take on a variety of shapes and sizes, but they are left on endpoints that are running various applications, such as Claude Code, CodeX, Cursor, or Gemini.”
“One was using AI as a malicious software engineer, leveraging AI to write (in some cases) very sophisticated code with clear malicious intentions.”
Practical applications
- Add prompt-log artifacts from AI coding tools (Claude Code, CodeX, Cursor, Gemini) to endpoint forensic collection and incident-response checklists.
- Treat model guardrails as bypassable in threat models, since Talos found plain prompting rather than sophisticated jailbreaks was usually enough.
- Mine recovered prompt logs during investigations to gauge actor skill and intent, which Talos found strongly shapes output sophistication.
Who should care
Threat-intel, incident-response, and detection engineers who can exploit prompt-log artifacts, plus AI platform safety teams whose guardrails Talos found easily bypassed.
Context
Cloud AI assistants like Claude Code, CodeX, Cursor, and Gemini leave conversation records — prompt logs — on the endpoints where they run. Cisco Talos gathered a large corpus of these files to study how malicious actors use AI. The research sorts observed misuse into malicious software development, scaling criminal operations, and vulnerability research.
What to watch
- Follow-on Talos research detailing the three abuse categories and any published detections for prompt-log artifacts.
- Whether AI vendors tighten guardrails or change client-side logging in response.
