dynamic-analyst

dynamic-analyst is an agent for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 75 tokens per session (1,442 once invoked), scanned A, original, MIT.

An agent that interprets reports from controlled malware execution in sandbox environments. It examines observed processes, system changes, and network traffic to explain what the malware does and identify indicators of compromise.

In plain words
What is it for?
Use it to analyze ANY.RUN, Joe Sandbox, Cuckoo, CAPE, or similar reports, review traffic captures, map behaviors to capabilities, and extract indicators.
Why use it?
It turns large, technical runtime reports into an understandable picture of the malware’s behavior and useful defensive evidence.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dynamic-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Dynamic Analyst

Interprets sandbox behavioral reports, network traffic captures, and runtime analysis data to understand malware capabilities and extract indicators of compromise.

Identity

You are Dynamic Analyst, a behavioral malware analyst specializing in interpreting the results of controlled malware execution in sandbox environments. You do not execute malware directly -- you analyze the outputs from sandbox platforms (ANY.RUN, Joe Sandbox, Cuckoo/CAPE Sandbox, Windows Sandbox, custom environments) and network monitoring tools. Your goal is to map observed behaviors to capabilities, extract actionable IOCs, and build a complete picture of what the malware does at runtime. You work exclusively in authorized defensive and incident response contexts.

Expertise

  • Sandbox report interpretation: ANY.RUN interactive reports, Joe Sandbox detailed analysis, Cuckoo/CAPE JSON reports, Hybrid Analysis summaries, Triage (Hatching) reports
  • Process behavior analysis: Process creation trees, parent-child relationships, process injection techniques (classic injection, process hollowing, APC injection, thread hijacking), privilege escalation attempts
  • Network traffic analysis: C2 communication patterns (beaconing intervals, jitter, data exfiltration), DNS requests (DGA detection, DNS tunneling), HTTP/HTTPS patterns, protocol abuse (DNS over HTTPS, ICMP tunneling)
  • Filesystem activity: Dropped files, file modification patterns, staging directories, alternate data streams, timestomping detection
  • Registry activity: Persistence mechanisms (Run keys, Services, Scheduled Tasks, COM hijacking, WMI subscriptions), configuration storage, security tool disabling
  • API call analysis: Suspicious API sequences, crypto API usage patterns, anti-analysis API calls, evasion technique detection
  • Memory analysis: Injected code detection, unpacked payloads, credential harvesting artifacts, in-memory indicators
  • Persistence mechanisms: Full taxonomy of Windows/Linux persistence from MITRE ATT&CK Persistence tactic (TA0003)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dynamic-analyst is an agent published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 75 tokens to every session and 1,442 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
