Endpoint Management Platforms Emerge as Prime Targets for Ransomware Attacks on MSPs and Enterprises

Endpoint management platforms have become essential for IT operations but also represent significant security risks because they provide attackers with trusted channels and elevated permissions once compromised. Recent incidents show how attackers abused BeyondTrust Bomgar, SimpleHelp, ConnectWise ScreenConnect, and Microsoft Intune to deploy ransomware and disrupt operations across multiple organizations. Traditional controls such as MFA and PAM operate within the platform's boundaries and cannot independently verify commands received by endpoints. Action1 addresses this gap with Endpoint Takeover Prevention, which uses customer-controlled cryptographic keys to authorize high-risk actions like script execution and software deployment. The approach ensures that even a full compromise of the cloud management infrastructure does not allow unauthorized sensitive operations without the owner's private key. Organizations are advised to re-evaluate protections around centralized management systems and implement independent verification mechanisms.

Endpoint management platforms have become essential in modern IT operations and enterprise security. They allow administrators to deploy patches, install software, execute scripts, enforce configurations, and remotely manage thousands of devices from a centralized system. Without these types of systems, maintaining consistent security across large environments would be extremely difficult and labor-intensive.

However, the administrative authority that makes these platforms valuable also makes them very attractive targets for attackers. An endpoint management platform already has established and approved communication channels, elevated permissions, and trusted relationships with the devices it manages. Any attacker who gains control of that infrastructure will be able to use those existing capabilities to distribute malware, execute malicious commands, disable security controls, or disrupt operations across an entire organization.

When trusted management infrastructure is compromised

Recent incidents demonstrate how compromised remote management infrastructure can extend attacks across compromised environments. In 2026, Huntress documented attackers abusing compromised BeyondTrust Bomgar remote support infrastructure to deploy ransomware and access downstream organizations. In 2025, ransomware operators compromised an MSP's SimpleHelp platform, using its existing management capabilities to access protected systems, steal information, and deploy ransomware. Similarly, in 2024, attackers exploited ConnectWise ScreenConnect vulnerabilities, with investigators documenting Play ransomware deployment through a compromised MSP instance. And who will forget the 2024 incident abusing Microsoft Intune to remotely wipe hundreds of thousands of corporate devices at Stryker!

These attacks against centralized management and software distribution systems often lead to compromise well beyond the initially compromised infrastructure. For cloud-hosted platforms, the security of the provider's hosting environment, management services, and software delivery mechanisms becomes particularly important.

Why traditional security controls have limitations

Multi-factor authentication, role-based access controls, privileged access management, and activity monitoring are bare minimum safeguards. They help restrict administrative access, limit permissions, and identify suspicious behavior. However, these protections primarily operate within the management platform's security boundaries. An attacker exploiting a vulnerability in the underlying system, compromising a privileged service, or hijacking an authenticated administrative session may be granted the ability to issue commands that endpoints recognize as legitimate.

The security implication is that high-risk endpoint operations should have authorization that remains verifiable independently of the management platform delivering them.

Adding owner-controlled authorization

Cryptographically verified authorization, independent of anything the platform stores or directly handles, provides the platform a way to establish that independent security boundary. Under this approach, sensitive endpoint operations require authorization signed using a private cryptographic key controlled only by the legitimate admin. The endpoint independently verifies the signature before executing the protected instruction.

Action1 implements this approach through Endpoint Takeover Prevention (ETP). ETP uses customer-controlled cryptographic authorization to protect high-risk operations, including script execution, software deployment, automations, and remote sessions. Because the private authorization key is maintained independently of Action1's cloud infrastructure, a compromise of the management platform alone does not provide the ability to authorize these protected actions.
