DevMan RaaS Portal Centralizes Payload Builds, Victim Management, and Affiliate Payouts

Researchers say DevMan, also tracked as Funky Mantis, operated a centralized ransomware-as-a-service platform with a dedicated affiliate portal for payload generation, victim management, ransom negotiation, earnings tracking, and internal coordination. PRODAFT reported the group was active from late 2025 into early 2026, used an 80/20 affiliate revenue split, and claimed 184 victims, with the heaviest concentration in the United States across technology, healthcare, financial services, professional services, and government. The operation explicitly pursued hospitals, critical infrastructure, the public sector, and law enforcement, and advertised a separate encryptor for SCADA environments, underscoring its focus on high-impact targets. Technical reporting links DevMan’s malware to DragonForce/Conti lineage while showing the operation evolved beyond a simple variant. Earlier analysis described a DragonForce-based sample marked by the .DEVMAN extension, SMB share probing, rapid encryption, and a builder flaw that encrypted its own ransom notes; later reporting identified a Rust-based Devman Locker using ChaCha20-Poly1305, appending .devman21, dropping RESTORE_FILES.txt, mounting network shares, disabling defenses, deleting shadow copies and event logs, and inhibiting recovery. The latest portal version reportedly supports Windows, Linux, and ESXi lockers and includes features for privilege checks, lateral movement, and security-tool impairment, indicating a mature and centrally managed extortion operation.

Muddled Libra Threat Assessment: Further-Reaching, Faster, More Impactful

Muddled Libra—also tracked as Scattered Spider and UNC3944—resumed intrusion activity with faster, broader operations across government, retail, insurance, and aviation organizations, relying heavily on voice-based social engineering to manipulate help desks and users into resetting credentials and MFA. Investigators reported the group often minimizes malware use, abuses legitimate tools and victim-owned assets, and can move from initial access to high privilege extremely quickly, including one case where domain administrator access was reached in about 40 minutes. Since at least April 2025, the actor has also worked with the DragonForce ransomware-as-a-service program, with incidents involving large-scale data theft followed by encryption. Separate technical analysis tied the group to the bedevil (bdvl) Linux userland rootkit used against VMware vCenter servers, where it hides LD_PRELOAD persistence by patching dynamic linker binaries to reference a randomly generated preload path instead of /etc/ld.so.preload. The technique is designed to evade normal inspection tools and can restore the original linker path during uninstall or backdoor-triggered cleanup. Researchers said defenders can uncover the hidden preload path by tracing the first file access of dynamically linked binaries and can identify tampering through package integrity checks such as rpm -V glibc or debsums, while stronger Microsoft Entra ID Conditional Access policies can materially slow the group’s cloud-focused operations and reduce ransomware impact.
