What is FraudGPT?

Written by IRONSCALES | Aug 12, 2025 9:57:53 PM

How FraudGPT Works

FraudGPT is believed to operate as a fine-tuned large language model (LLM) that has been trained or prompted with datasets drawn from malicious code repositories, phishing templates, and prior breach data. It is typically distributed through darknet marketplaces, encrypted chat channels, or invite-only criminal communities.

Phishing Campaign Automation

FraudGPT can generate fully formed phishing emails that include:

  • Context-specific lures based on industry jargon or current events
  • Dynamic placeholder fields for victim personalization
  • Embedded links pointing to fraudulent landing pages or credential harvesters
  • HTML or CSS formatting that mimics legitimate brands and avoids spam-triggering keywords

Malware and Exploit Development

The model can produce code snippets in languages like Python, JavaScript, PowerShell, or C# that may be adapted into:

  • Keyloggers and data exfiltration scripts
  • Exploit proof-of-concepts targeting known CVEs
  • Polymorphic code that changes its signature to evade detection
  • Obfuscated payloads that bypass static antivirus checks

Social Engineering Support

FraudGPT can write conversational scripts for voice phishing (vishing) or chat-based scams, complete with natural-sounding dialogue, psychological persuasion techniques, and objection handling.

Why FraudGPT is Dangerous

FraudGPT represents a shift in threat actor capability because it merges automation, personalization, and technical sophistication in a single platform. Attacks that would have required multiple skill sets or weeks of preparation can now be executed in minutes.

Lowering the Barrier to Entry

Inexperienced cybercriminals can launch advanced attacks without deep coding knowledge. The AI provides step-by-step instructions for deploying phishing kits, integrating malware into documents, or exploiting vulnerabilities.

Scaling Targeted Attacks

The model can replicate spear phishing messages across hundreds of recipients, each customized with unique details. This reduces detection by pattern-matching security tools and increases success rates.

Adversarial Evasion Techniques

FraudGPT can suggest ways to bypass common defenses such as:

  • Using URL shorteners and redirect chains to hide malicious destinations.
  • Embedding malicious code in uncommon file types or compressed archives.
  • Randomizing syntax and structure in phishing content to defeat content-based filters.

FraudGPT vs. GhostGPT vs. WormGPT

While all three names refer to malicious AI tools, they differ in focus and marketing:

  • FraudGPT is positioned as an all-in-one cybercrime assistant with capabilities for phishing, malware creation, and fraud scripting.

  • GhostGPT is often marketed as a stealth-oriented tool focused on generating highly personalized spear phishing and BEC attacks with an emphasis on evading detection.

  • WormGPT is presented as a malware and exploit creation specialist, with features for writing polymorphic code and identifying vulnerabilities for penetration testing or abuse.

FraudGPT overlaps with both but is broader in scope, combining the phishing emphasis of GhostGPT with the code generation capabilities of WormGPT.

How IRONSCALES Protects Against FraudGPT-Generated Threats

IRONSCALES uses Adaptive AI and crowdsourced threat intelligence to identify suspicious patterns at the inbox level, even when phishing content is AI-generated and highly convincing.

Key defense capabilities include:

  1. Real-time anomaly detection based on sender behavior, tone, and relationship history.
  2. Automated quarantine and remediation of AI-crafted phishing campaigns.
  3. Phishing simulation and security awareness training to prepare employees for emerging AI-enabled threats.
  4. Continuous updates from global IT teams to adapt detection models as new AI attack tools emerge.
