Aurora Ransomware Operators Use Cursor AI in Attacks Against 10 Targets

Aurora ransomware operators used Cursor AI running Claude Sonnet to plan and execute intrusions against dozens of organizations in nine countries.

CloudSEK and Gambit Security analyzed exposed infrastructure tied to the Russian-speaking Aurora (Aur0ra) group, revealing months of activity against more than 20 organizations across nine countries between April and July 2026, with 33 victims listed by Ransomware.Live. The operator used the Cursor agentic coding assistant to plan attacks in Russian, including an AD CS exploitation plan, and Gambit observed Cursor Agent (running Anthropic's Claude Sonnet) performing hands-on exploitation tasks such as Nmap scanning, NetExec enumeration, NTLM relay, and certificate attacks against 10 targets. Attacks begin with email bombing plus IT help desk vishing via Xray-core, followed by SMB/LDAP/WinRM/RDP lateral movement, log clearing, Defender disabling, and exfiltration; the Windows and Linux/ESXi encryptors are built from a single Zig codebase, with shadow copy deletion and VM-killing before encryption.

Threat Actors Abuse Cursor Agent AI to Assist Ransomware Operations

Aurora ransomware operators are using SpaceX-owned Cursor's AI agent to perform reconnaissance and exploitation tasks during intrusions.

The Aurora ransomware group is abusing the Cursor Agent AI coding tool to automate reconnaissance and exploitation activities during its operations. This marks a notable case of criminals weaponizing an AI coding agent inside their attack workflow. Cursor was recently acquired by SpaceX, drawing extra attention to the tool's abuse.

AI agents carried out every step of this ransomware attack – then left the victim an 80-page security audit

Unit 42 says a human attacker used AI agents to execute a full ransomware intrusion in under 10 hours, leaving the victim an 80-page security audit.

Palo Alto Networks Unit 42 incident responders report a human ransomware operator used frontier AI models and agentic attack frameworks to breach an enterprise in under 10 hours, work that normally takes human operators around two weeks. AI agents performed reconnaissance, breached a public API endpoint to tunnel into the network, scraped code repositories for hard-coded tokens and service passwords, then used them to steal master administrative credentials from the secret-management system for root access. Specialist pivot agents validated access to cloud, identity, CI/CD, container and SaaS environments, and the attacker hijacked CI/CD workflows to steal cloud keys and turn the victim's cloud AI services into post-compromise infrastructure. The agents left an 80-page audit detailing dozens of exploited findings.

Medusa ransomware tallies hundreds of new victims, says updated advisory on group’s tactics

CISA, FBI, and HHS updated their Medusa ransomware advisory, reporting over 500 victims and detailing the gang's access-broker and exploit tactics.

A joint advisory update from CISA, the FBI, and HHS expands the March 2025 Medusa guidance, drawing on a year of FBI investigations. The ransomware-as-a-service group's known victim tally grew from more than 300 to more than 500 between March 2025 and April 2026, with the Healthcare and Public Health sector frequently hit. Medusa pays access brokers $100 to $1 million, has exploited flaws such as Fortra GoAnywhere and BeyondTrust vulnerabilities, and leverages newly announced exploits within 24 hours, sometimes a week before public disclosure. The group uses living-off-the-land techniques, remote monitoring and management software, and RDP for lateral movement, and has been linked to actors including Microsoft-tracked Storm-1175 and North Korean hackers targeting healthcare.

ATF confirms cyberattack hit system containing info on its investigation targets

Qilin ransomware group claimed breaching the ATF, exposing data on investigation targets; the agency says a standalone system was hit with no mission impact.

The Bureau of Alcohol, Tobacco, Firearms and Explosives confirmed a cyberattack on a standalone system holding information about targets of ATF investigations, designated a major incident, with no impact on case management, lab, or eForms systems. Qilin, a Russian-speaking affiliate-based ransomware group, claimed responsibility, though ATF declined to confirm involvement or the root cause. Qilin has claimed hundreds of victims across 60+ countries since 2022 and partners with Scattered Spider and Moonstone Sleet.

Harley-Davidson Alleged Breach – CL0P Ransomware Adds Motorcycle Maker to the List

CL0P ransomware group listed Harley-Davidson on its extortion leak site, claiming a compromise; the motorcycle maker has not confirmed any breach.

The CL0P ransomware operation added Harley-Davidson to its public extortion portal, a listing highlighted by the ransomNews monitoring account on September 10, 2026. Harley-Davidson has not confirmed any compromise, and the initial access method, affected business unit, timing, and volume of stolen data remain unknown, with no sample files or technical indicators published. The article stresses that leak-site listings alone do not confirm a breach and can serve as negotiation pressure in double-extortion schemes. If verified, stolen data could fuel downstream phishing, BEC, credential-stuffing, and invoice fraud targeting dealers, suppliers, and customers.
