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.

Gunra Ransomware Exploits Fortinet FortiOS, FortiProxy Flaws to Breach Networks

CISA, FBI, and South Korean agencies warn Gunra ransomware, with 51 victims since April 2025, exploits Fortinet flaws for double-extortion attacks on critical infrastructure.

CISA, the FBI, and South Korean agencies warned of Gunra ransomware attacks targeting healthcare, financial services, government, and professional services worldwide. The Conti-derived operation exploits internet-facing Fortinet FortiOS and FortiProxy flaws CVE-2024-55591 and CVE-2025-24472 for initial access, then deploys double extortion with Salsa20/ChaCha20 encryption and publishes non-payers on a leak site within five to seven days. Ransomware.Live lists 51 victims since April 2025, mostly in South Korea, Brazil, Spain, Thailand, and Hong Kong. The group uses Impacket tools for SMB lateral movement and NTDS credential dumping, tampers with VDI authentication to accept a designated OTP value to bypass MFA, and launched a RaaS affiliate program in January 2026 under the new alias Golden Community.

CVE-2024-555919.898%
Unauthenticated Super-Admin Bypass in Fortinet FortiOS and FortiProxy
CVE-2024-55591 is an authentication bypass (CWE-288) in the Node.js websocket module of Fortinet FortiOS and FortiProxy that lets a remote, unauthenticated attacker gain super-admin privileges via crafted websocket requests. It affects FortiOS 7.0.0 through 7.0.16 and FortiProxy 7.0.0 through 7.0.19 and 7.2.0 through 7.2.12, and is trivially triggerable from the network with no user interaction given network access to the management/websocket interface. Successful exploitation gives full super-admin control of the appliance, which attackers can use to pivot, create persistent access, and deploy ransomware. Any organization running the affected FortiOS or FortiProxy versions, especially with admin interfaces reachable from the internet, is affected. Exploitation is confirmed in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2025-01-14, and multiple ransomware crews (reported as Gunra, SuperBlack, and Mora_001) are actively exploiting it.

CVE-2025-244728.17%
Authentication Bypass in Fortinet FortiOS and FortiProxy Grants Super-Admin Access
CVE-2025-24472 is an authentication bypass (CWE-288) in the Fortinet Security Fabric of FortiOS and FortiProxy. A remote, unauthenticated attacker who already knows the serial numbers of both the upstream and downstream devices can send crafted CSF proxy requests to gain super-admin privileges on the downstream device; the attack only works where the Security Fabric is enabled, and the need for serial-number knowledge raises attack complexity. An attacker gains full super-admin control of the downstream Fortinet device, which can serve as a foothold for network-wide compromise. Organizations running affected FortiOS 7.0.x or FortiProxy 7.0.x/7.2.x builds with Security Fabric enabled are in scope. The flaw was added to CISA's KEV catalog on 2025-03-18 with known ransomware use, and multiple ransomware groups (including Gunra, SuperBlack, Mora_001 and Qilin operators) have been reported exploiting Fortinet firewall flaws in recent campaigns.
