Cybersecurity researchers have discovered an artificial intelligence (AI)-driven intrusion ecosystem run by affiliates of the INC and The Gentlemen ransomware groups.
Central to the operation is an “Autonomous Red Team Kill Chain Framework” referred to as Phantom. The threat actor is assessed to be Russian-speaking and functions both as an intrusion and data-extortion operator, as well as an infrastructure provider supporting different partners across the ransomware ecosystem.
“The operators exploited edge and remote-access systems at scale, including FortiClient EMS, SimpleHelp, cPanel, and VPN gateways,” SOCRadar said. “They used AI-managed knowledge bases to track victims, stolen credentials, and campaign progress.”
A notable aspect that defines the campaign is its “AI-executed, human-approved operating structure” in which a human operator provides a victim-specific prompt and reviews every step, while the intrusions themselves are executed through OpenCode with OpenRouter-hosted commercial models.
An examination of the exposed directory at 45.227.254[.]43 has revealed the activity logged 8,257 messages across 133 sessions. Should the models refuse to act on the prompts, the operator has been found to rewrite requests as an authorized red team assessment instead of simply switching models.
Initial access is achieved by exploiting public-facing edge devices at scale, following which the attackers move laterally, establish persistence, exfiltrate data, and escalate toward ransomware deployment. Operator records indicate that the attacks involve the exploitation of the following flaws –
“Once inside, the operators followed a recurring lifecycle: enumerate the domain, escalate to domain admin where possible, harvest credentials with stealer tooling, prioritize finance, HR, legal and executive files, and collect them over reverse-SOCKS tunnels,” SOCRadar said.
“Credential reuse was the main force multiplier; in one case, a single reused password unlocked the VPN, servers, RMM, backup and security management platforms at once. Security products were impaired with a BYOVD killer and loader-level evasion, although the operators’ own logs record mixed results against enterprise EDRs.”
Supporting the threat actor in their goals is a diverse toolkit comprising bespoke frameworks, modified open-source tools, and compiled binaries –
- Phantom, an AI-powered offensive security and penetration testing framework that’s deployed in live operations via OpenCode and employs an agent that communicates with an external server to retrieve tasks, execute commands, and return outputs. It supports 18 skill modules to facilitate reconnaissance, binary reverse engineering, exploit research, steganography, telemetry assessment, and EDR fingerprinting, among others.
- WormGPT-MCP, a set of 32 Model Context Protocol (MCP) servers connecting the AI system to 32 different modules that span functions ranging from reconnaissance to extortion.
- Ghost C2, a collection of three generations of polymorphic implants that communicate with a remote server over Cloudflare, Telegram, or DNS, and execute tasking and maintain persistent beacons on compromised endpoints.
- RevSocks, a reverse SOCKS5 framework used to pivot inside victim networks and stage data for exfiltration.
Other tools include a Cloudflare-fronted Mythic agent dubbed QuickLine, a Quick Heal/Seqrite EDR killer that abuses the Zemana driver (“zam64.sys”) as part of a BYOVD attack, and exfiltration programs such as rks3 and BackupAgent.
Analysis of dozens of AI-authored extortion records shows that the threat actors adopt a data-centric approach. It involves examining the stolen financials to determine the amount a victim can pay without having to involve a bank or an insurer, and then sending masked proof samples and ramping up pressure through scripted vishing calls and threatening to notify customers, partners, and regulators.
The stolen data is eventually published on the data leak site if the victim fails to pay within a 24-72 hour deadline. That said, the final outcomes of these ransom demands are unknown as no cryptocurrency wallet or payment record has been recovered.
A total of 62 organizations are estimated to have been targeted by the operation, out of which four of them ended up being listed on the data leak sites for INC and The Gentlemen ransomware. The U.S. accounts for more than 50% of the targets. The attacks also primarily targeted industrial, manufacturing, and energy sectors, followed by healthcare and pharmaceutical organizations.
“Across this exposed infrastructure, the actors engaged in widespread exploitation of exposed internet services, specifically targeting FortiClient EMS gateways, Ivanti/Citrix/SonicWall/OpenVPN gateways, SimpleHelp remote management servers, and cPanel hosting controls,” SOCRadar said.
“Concurrently, they orchestrated operations via the Phantom framework, established RevSocks reverse-SOCKS proxies for network pivoting, deployed Ghost C2 variants, and utilized AI-managed knowledge bases to meticulously log victim telemetry, compromised credentials, and active campaign statuses.”
