Surge in Cyberattacks Leveraging RMM Tools for Malware Deployment
Cybercriminals have increasingly targeted remote monitoring and management (RMM) tools to deploy malware and conduct large-scale cyberattacks. In 2025, attacks on RMM tools surged, with 51 different solutions identified as targets by security researchers. RMM tools, which became more prevalent during the COVID-19 pandemic to support remote work, are now being weaponized by threat actors due to their deep integration into enterprise IT environments. These tools, such as SuperOps and TeamViewer, are commonly used by IT professionals and managed service providers (MSPs) to remotely monitor, manage, and maintain client systems through centralized dashboards. Adversaries exploit these platforms by obtaining authenticated credentials, allowing them to bypass traditional security alerts and alarms. Once inside, attackers can disable scheduled backups, destroy system images and restore points, and push ransomware or other malicious payloads to thousands of endpoints simultaneously. The legitimate appearance of RMM tool traffic often allows malicious activity to evade anomaly detection systems, creating a persistent blind spot for network defenders. The elevated permissions typically granted to RMM platforms enable attackers to escalate privileges, move laterally within networks, and deliver malware efficiently. Compromising an MSP’s RMM infrastructure can have a supply chain effect, enabling attackers to pivot into multiple client environments and significantly amplifying the potential impact. This method of attack not only increases the blast radius but also enhances the monetization opportunities for cybercriminals. Security experts warn that the widespread use and trust in RMM tools make them an attractive and effective vector for cyberattacks. Organizations are urged to implement stronger authentication, monitor RMM tool usage closely, and restrict access to minimize risk. The trend highlights the need for enhanced vigilance and updated security controls around remote access and management solutions. The attacks demonstrate how tools designed for convenience and efficiency can become significant liabilities if not properly secured. The ongoing exploitation of RMM tools underscores the evolving tactics of cybercriminals in targeting trusted IT infrastructure. As attackers continue to refine their methods, defenders must adapt by prioritizing the security of remote management platforms. The surge in RMM tool exploitation serves as a stark reminder of the importance of supply chain security and the risks posed by third-party service providers. Organizations should review their incident response plans to ensure rapid detection and containment of attacks involving RMM platforms. The cybersecurity community continues to monitor this threat landscape, emphasizing the critical need for proactive defense measures.

Attackers Abuse RMM Tools and Bomgar RCE to Breach MSPs and Deploy Ransomware
Threat actors increasingly abused legitimate remote monitoring and management (RMM) software for initial access, persistence, credential theft, and defense evasion, with Huntress reporting that RMM abuse accounted for 24% of incidents it observed and surged 277% over the prior year. Campaigns used signed tools including **Action1**, **ScreenConnect**, **HeartbeatRM**, **AnyDesk**, **Atera**, and **SimpleHelp**, often chaining multiple products together to fragment telemetry and complicate containment. Delivery methods included phishing lures themed around the Social Security Administration and invitations, GitHub-hosted payloads, Cloudflare-protected sites, Windows-only filtering, and mobile-only credential harvesting pages; Huntress also observed low-maturity operators using LLM-generated scripts, VPS infrastructure, proxy tooling, combo lists, and utilities designed to hide RMM software from uninstall lists. Huntress also linked a sustained rise in compromises involving **Bomgar** instances to exploitation of **`CVE-2026-1731`**, a critical remote code execution flaw in BeyondTrust products, with attackers targeting outdated deployments to access victim networks and pivot into downstream customer environments. Reported incidents hit MSPs and software providers, including a ransomware attack affecting three downstream companies and another MSP breach that forced the isolation of 78 businesses while attackers moved into four customer environments. In affected networks, intruders created privileged accounts, added users to **Domain Admins**, ran reconnaissance with **NetScan** and **`nltest.exe`**, deployed suspicious drivers such as **PoisonX.sys** and **HRSword.exe**, and in several cases launched **LockBit** or a likely leaked-builder variant, underscoring the need to patch BeyondTrust systems, tightly govern trial and remote-access tooling, and monitor for unauthorized RMM activity.

Abuse of Legitimate Remote Access Tools for Lateral Movement and Persistence
Threat actors are increasingly leveraging legitimate remote access tools, such as PuTTY and various remote monitoring and management (RMM) platforms, to facilitate lateral movement, data exfiltration, and persistent access within compromised networks. Attackers exploit the "living off the land" nature of these tools, blending their malicious activities with normal administrative operations to evade detection. In the case of PuTTY, adversaries use binaries like `plink.exe` and `pscp.exe` to move laterally and exfiltrate sensitive data, often leaving behind subtle forensic traces such as SSH host keys in the Windows registry. These artifacts can be crucial for investigators to reconstruct attacker activity, even after extensive log and artifact cleanup by the attackers. Similarly, security researchers have observed a surge in incidents where multiple RMM tools are abused in attack chains. Threat actors compromise or install RMM platforms like ScreenConnect, TeamViewer, Atera, NinjaRMM, and GoTo Resolve to maintain long-term access and persistence. Attackers often use phishing lures to trick victims into installing rogue RMM software, and may deploy several RMM tools in succession to ensure continued access even if one is detected and removed. These tactics highlight the ongoing challenge for defenders in distinguishing between legitimate and malicious use of remote access utilities, underscoring the need for robust monitoring and baselining of such tools within enterprise environments.

Threat Actors Expand Remote Monitoring and Management Abuse With Fake RMM Malware
Proofpoint reported a new **malware-as-a-service (MaaS)** offering that masquerades as a legitimate remote monitoring and management (RMM) product, branding itself as **TrustConnect** (delivered as “TrustConnect Agent”). Proofpoint assessed with *moderate confidence* that the actor behind TrustConnect was also a prominent user of **Redline stealer**, and said it worked with intelligence partners to disrupt parts of the malware’s infrastructure; the actor quickly showed resilience by standing up another fake RMM-themed site advertising a related malware variant called **DocConnect**. Proofpoint highlighted that attackers continue to favor RMM-style tooling for initial access and post-compromise control because it blends into normal enterprise remote support activity. Separately, Dark Reading summarized findings from Huntress’ 2026 Cyber Threat Report indicating a broad surge in **RMM abuse** as an intrusion strategy, citing a **277% year-over-year increase** in malicious RMM deployments and a corresponding decline in traditional malware usage. The report described RMM tooling as attractive to threat actors for stealth, persistence, and operational efficiency, and noted commonly abused products including **ConnectWise ScreenConnect**, **AnyDesk**, **Atera**, **NetSupport**, **PDQ Connect**, and **Splashtop**, with healthcare and technology seeing the largest increases. Together, the reporting underscores both the industrialization of RMM abuse and the emergence of purpose-built “fake RMM” malware offerings designed to look like enterprise remote support software.
