SpamGPT has surfaced on underground forums as an all-in-one spam and AI-powered phishing toolkit, marketed by cybercriminals as a breakthrough for email-based attacks.
Cybersecurity researchers at Varonis warn that the platform mimics enterprise marketing software but is weaponized for phishing and malware delivery.
By combining generative AI with automated campaign tools, SpamGPT is being advertised as a “game-changer” for attackers.
The interface resembles a commercial email marketing dashboard, complete with campaign management, deliverability testing, and analytics. Unlike legitimate platforms, SpamGPT provides modules for spoofing, bulk SMTP imports, and inbox monitoring, which are features designed to maximize phishing effectiveness.
“This platform is designed to compromise email servers, bypass spam filters, and orchestrate mass phishing campaigns with unprecedented ease.
SpamGPT combines the power of generative AI with a full suite of email campaign tools, lowering the barrier for launching spam and phishing attacks at scale.”
Varonis highlights that the platform has its own AI assistant dubbed KaliGPT, a feature that allows fraudsters to generate phishing email content.
“This means attackers no longer need to write convincing phishing emails; they can ask the AI for persuasive scam templates, subject lines, or targeting advice within the spam toolkit.”
SpamGPT’s developers emphasize scale and precision. The system “promises guaranteed inbox delivery for popular email providers (Gmail, Outlook, Yahoo, Microsoft 365, etc.),” and claims to bypass spam filters by abusing trusted services like Amazon AWS and SendGrid.
Another component, called “SMTP cracking mastery,” teaches buyers how to generate or steal server credentials in bulk.
“What used to require a team of skilled developers can now be accomplished by a single bad actor with a $5,000 toolkit.”
Varonis tells firms to take security steps to avoid falling prey to SpamGPT abusers.
“Enterprises should think about hardening their email defenses: enforce strong email authentication (DMARC, SPF, DKIM) to make spoofing harder, and use AI-powered email security solutions that can detect the subtle signatures of AI-generated phishing content.”
