An uncensored AI
for malware analysis.

Malware analysis is corpus-scale pattern matching where the marginal cost of a new sample should drop to zero once your pipeline is in place.

Senior analysts spend their best hours setting up that pipeline. Junior analysts spend their day triaging samples one at a time because the pipeline is not in place yet. AI assistance should fix that. Instead, the major coding assistants — Claude, ChatGPT, Cursor, Copilot — refuse to engage with malware samples on principle, treating defensive incident response and threat intelligence as if they were attacker workflows. The refusal is uniform and structural; you cannot rephrase your way past the policy. TartarusAI writes the triage harness, the YARA rule, the unpacker, the family classifier — without the moralizing about why a sample is malware. The agent treats malware analysis the way every commercial threat-intel platform already does: as a defensive discipline that does not need to justify itself to the tooling. Same enterprise-grade runtime safety guards. Content policy, off.

// what it does

What you ship
when nothing refuses.

Sample triage at scale

Static + behavioral analysis harnesses, IOC extraction (network, registry, mutex, file, persistence indicator), family clustering, capability scoring against MITRE ATT&CK. Run it across 10K samples and get back a clean dataset, not a folder. Output integrates with VirusTotal, MISP, TheHive, Cortex, GRR, Velociraptor.

Custom YARA + capa rules

Sample → distinguishing features → YARA rule that will not false-positive. Positive-set + negative-set tuning for precision/recall calibration. Capa-style capability extraction for behavior-based detection. Iterates against your corpus until the precision/recall trade-off is where you need it.

Packer / crypter unwrapping

Identify the layer, write the unpacker, dump the inner payload. Custom packers, custom crypters, custom string-obfuscation schemes — the agent writes the de-obfuscator without lecturing about the sample. Particularly strong on the cottage-industry packers in the long tail of malware families.

Threat-intel writeups

Sample analysis → blog-quality writeup. TTP mapping to MITRE ATT&CK, IOC tables, screenshot annotation suggestions, executive summary, technical deep-dive. Cuts the worst part of malware research — turning a week of analysis into something the rest of the team can read.

Detection engineering

YARA rule writing, Sigma rule generation for SIEM detection, EDR custom-rule contributions (CrowdStrike CQL, SentinelOne STAR, Defender KQL), Suricata / Snort signatures for network detection. The agent writes the rules from samples, you tune the precision against your false-positive budget.

Family classification + lineage tracking

Sample clustering by code reuse, by toolkit lineage, by author fingerprint. Useful for tracking actor evolution across campaigns and for de-duplicating triage work when the same family lands in your queue under different SHAs.

// workflow

IR triage at corpus scale

A sample lands in your queue. The traditional flow: open it in IDA / Ghidra, spend two hours figuring out what it is, write the YARA rule by hand, push to detection, move on. The TartarusAI flow: drop the sample (or the corpus) into the agent, get back static feature extraction + behavioral tags + family classification + draft YARA in minutes. You spend the saved hours on the samples that actually require deep human analysis.

For a real IR queue, the bigger win is the pipeline rather than the individual sample. The agent writes the triage harness once, then runs it across every new sample of that family without further human input. You get a clean dataset, the queue depth drops, and the senior analysts get their week back.

For threat-intel teams, the writeup is usually the bottleneck. You have done the analysis, you understand the sample, and now you need to turn it into something the rest of the org can act on. The agent ghostwrites the writeup from your annotated analysis notes — TTP mapping, IOC tables, screenshot annotation suggestions, executive summary, technical deep-dive. You review, edit, publish.

// integrations

Fitting into your existing IR + TI stack

TartarusAI does not replace VirusTotal, MISP, TheHive, Cortex, GRR, Velociraptor, OSQuery, or your custom SIEM. It writes the scripts that drive them. Custom MISP feed parsers, TheHive case templates, Cortex analysers, GRR / Velociraptor flows, OSQuery configurations, custom SIEM detection rules.

Outputs are raw scripts and structured data — JSON, CSV, YARA, Sigma. No SaaS lock-in, no proprietary format. You commit them to your detection-engineering repo and run them on your existing infrastructure. For Enterprise customers, on-prem deployment supports IR work where the sample data absolutely cannot leave the perimeter.

  • Pairs with VirusTotal, MISP, TheHive, Cortex, GRR, Velociraptor, OSQuery, your custom SIEM.
  • Generates YARA rules, Sigma rules, custom EDR detection (CrowdStrike CQL, SentinelOne STAR, Defender KQL), Suricata / Snort signatures.
  • Outputs are raw rules and scripts you commit to your detection-engineering repo.
  • Enterprise tier supports on-prem for sample data that cannot leave the perimeter.

// discipline

Why malware analysts need an uncensored model

Every IR analyst, every threat-intel researcher, every detection engineer has the same experience: they ask Claude or ChatGPT to help with a sample, the model refuses because the prompt mentioned "malware," and they switch back to the disassembler. The big assistants treat all malware-adjacent work as adversarial because the content policy cannot tell the difference between an analyst doing IR and a wannabe author writing their first dropper.

The cost of this conflation is paid by the defenders. Every minute a senior analyst spends arguing with the AI is a minute they are not analysing samples, writing detection rules, or training junior analysts. Every junior analyst stuck without senior-level pair-programming because the AI refuses is a junior analyst whose ramp is slower than it has to be.

TartarusAI removes the content layer entirely for malware analysis work. Sample triage, IOC extraction, YARA writing, packer unwrapping, family classification, threat-intel writeups — all in scope. The agent reads the disassembly, writes the analysis script, ports the unpacker, and treats the work as the defensive discipline it actually is. Runtime safety guards stay in place; they protect your project, not the model from your prompt.

// questions

What people actually ask.

Will it analyze live malware samples without refusing?+
Yes. Malware analysis is a core defensive discipline. The agent reads the disassembly, writes the analysis script, ports the unpacker — same as you would expect from a tool that takes IR work seriously. No "this could be misused" preamble.
Can it work with disassembly / decompilation directly?+
Paste IDA / Ghidra pseudocode, raw x86 / x64 / ARM / MIPS / RISC-V assembly, or radare2 output. The agent reasons over it like a competent reverse engineer would.
Does this fit into existing IR pipelines?+
Yes. The agent writes scripts you call from your existing tooling — VirusTotal, MISP, TheHive, Cortex, Velociraptor, GRR, OSQuery. Not a SaaS lock-in. Output is raw scripts and JSON you commit to your detection-engineering repo.
What about anti-debug / anti-VM / sandbox detection?+
Same answer. The agent identifies the technique, writes the bypass, helps you build a sandbox or unpacker that handles it. No moralizing about why a sample uses anti-analysis.
Can I use it on samples under embargo / NDA?+
Yes. We do not train on prompts and sessions auto-purge after 24h. For research where the sample data absolutely cannot leave your perimeter, Enterprise tier supports on-prem deployment.
Does it write Sigma rules / SIEM detections, not just YARA?+
Yes. Sigma for cross-SIEM detection, plus vendor-specific rules: CrowdStrike CQL, SentinelOne STAR queries, Defender KQL, Splunk SPL, Elastic ESQL. The agent reads the sample behaviors and writes the detection at the right level for your SIEM.
How does it cluster by family vs author / actor?+
Code reuse analysis (string overlap, function-hash similarity, control-flow similarity), toolkit lineage tracking (Cobalt Strike Beacon variants, Brute Ratel variants, custom-loader families), behavioural fingerprinting (C2 protocol fingerprint, persistence pattern, evasion stack). Output is structured cluster data, not just "yes these are related."
What about ransomware analysis specifically?+
Particularly strong area. Encryption scheme reversal (custom AES variants, RSA key handling, file-marker patterns), config extraction, victim-keyed decryption analysis, recovery feasibility assessment. Useful for IR teams trying to determine recovery options before paying.
