The Qilin ransomware group, active since July 2022 and utilizing Golang, has claimed a new victim, Danone (International Delights) in the US Agriculture and Food Production sector, employing double extortion tactics involving data encryption and threatened data release.

Adversaries are leveraging legitimate Remote Monitoring and Management (RMM) and remote access tools on Windows endpoints for command-and-control, persistence, and execution, with detection focusing on the first observed instance of these tools on a host.

A cryptojacking campaign targets systems with high-performance GPUs using SEO poisoning and manipulated AI chatbot recommendations, distributing malware disguised as legitimate software utilities to establish persistence and evade detection before deploying GPU mining programs.

An active cryptojacking campaign uses SEO poisoning, AI chatbot interactions, and ScreenConnect abuse to target high-performance PCs, aiming to maximize GPU mining yield and establish persistent remote access for potential data theft or ransomware attacks.

Ransomware-as-a-service (RaaS) attacks leverage affiliates for initial access, persistence, and exfiltration, using varied techniques like compromised RDP, vulnerable VPNs, and rogue RMM tools, impacting multiple organizations in a single campaign.

A malspam campaign is leveraging the Tiflux RMM to gain remote access and persistence on victim machines, abusing legitimate remote management software for stealthy access and persistence.

The April 2026 Red Canary Intelligence Insights highlights the axios npm compromise, TeamPCP's LiteLLM compromise via PyPI, and a surge in Microsoft Teams phishing, leading to RAT deployment, credential harvesting, ransomware deployment, or data theft.

This rule identifies suspicious child processes spawned by ScreenConnect client processes, potentially indicating unauthorized access and command execution abusing ScreenConnect remote access software to perform malicious activities such as data exfiltration or establishing persistence.

CVE-2024-1708 is a path traversal vulnerability in ConnectWise ScreenConnect that could allow an attacker to execute remote code or directly impact confidential data and critical systems.

Detects a suspicious sequence of an MSI installer execution immediately followed by the execution of commonly abused Remote Management Software, potentially indicating unauthorized remote access.

Detection of ScreenConnect clients connecting to a newly observed host server outside the official ScreenConnect cloud, potentially indicating command and control activity or compromise.

This rule identifies Windows hosts where two or more distinct remote monitoring and management (RMM) or remote-access tool vendors are observed starting processes within the same eight-minute window, potentially indicating compromise, shadow IT, or attacker staging of redundant access.

Detects process creation events indicative of remote management tools, potentially signifying legitimate use or malicious exploitation by threat actors abusing RMM software.

This detection identifies a Windows host where two or more distinct remote monitoring and management (RMM) or remote-access tool vendors are observed starting processes within the same eight-minute window, potentially indicating compromise, shadow IT, or attacker staging of redundant access.
