Detect Dell RecoverPoint for Virtual Machines (RP4VMs) Hard-coded Credentials Exploitation in Sumo Logic CSE

Detects exploitation of CVE-2026-22769, a hard-coded credentials vulnerability in Dell RecoverPoint for Virtual Machines (RP4VMs). Threat actors (including UNC6201) have actively exploited this zero-day to gain unauthorized access to RP4VMs appliances, enabling lateral movement, data exfiltration, and ransomware deployment within virtualized environments. The hard-coded credentials allow unauthenticated remote access to RP4VMs management interfaces.

False Positives & Tuning

  • Default username retention post-deployment before admin hardening procedures are applied
  • Vendor Dell support access using factory-default credentials under a support contract
  • Automated replication health checks using legacy service account credentials
  • SIEM test log injection or replay exercises that include default RP4VMs credential patterns

Testing Methodology

Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.

  1. Test 1RP4VMs Default Credential SSH Authentication Simulation

    Expected signal: SSH authentication event in /var/log/auth.log on the target RP4VMs appliance showing 'Accepted password for admin from <attacker_ip>'. SIEM should receive this via syslog forwarding from the appliance.

  2. Test 2RP4VMs Post-Exploitation Command Execution via Hard-coded Credentials

    Expected signal: SSH session opened for user 'support' followed by process execution events (cat, ps, netstat/ss, find) visible in Auditd or Falco telemetry if deployed on the RP4VMs Linux host.

  3. Test 3RP4VMs Credential Discovery — Searching for Additional Credentials Post-Compromise

    Expected signal: Auditd EXECVE syscall events for grep, cat, and env commands executed under the 'boxmgmt' user context on the RP4VMs host. File access events for /etc directory traversal.

  4. Test 4RP4VMs Persistence — Unauthorized SSH Key Installation

    Expected signal: File write event to ~/.ssh/authorized_keys under the 'admin' user account on the RP4VMs host. Auditd or Falco should capture the open/write syscalls against the authorized_keys file path.
