This hypothesis targets the presence of known Logedrut indicators of compromise, which are frequently used by threat actors to establish persistence and execute malicious payloads within Azure environments. Proactively hunting for these IOCs allows the SOC team to identify compromised assets early, mitigating the risk of lateral movement and data exfiltration associated with this high-severity threat.
Malware Family: Logedrut Total IOCs: 3 IOC Types: sha256_hash, sha1_hash, md5_hash
| Type | Value | Threat Type | First Seen | Confidence |
|---|---|---|---|---|
| sha256_hash | c13cea04f598e2b0c248d603a6e31bd13aabb64d8149c1b6a77b64e0b983a86f | payload | 2026-09-24 | 95% |
| sha1_hash | f495880eb6ee7bb930a9957f092f395695cf89a4 | payload | 2026-09-24 | 95% |
| md5_hash | 833cdd365d2dd29832a711dc2da5a584 | payload | 2026-09-24 | 95% |

Legacy Application Patching via Scheduled Tasks: An IT operations team uses a custom PowerShell script executed by a Windows Scheduled Task (e.g., AppPatch_Update.exe) to apply security patches to a legacy Java-based enterprise application. The script downloads a specific JAR file from an internal repository, which shares a hash or path pattern with one of the Logedrut IOCs.
C:\Program Files\LegacyApp\bin\patcher.exe or where the parent process is schtasks.exe and the command line contains AppPatch_Update.Third-Party Agent Telemetry Collection: A security monitoring agent (e.g., CrowdStrike Falcon or Carbon Black) collects telemetry data from a specific service account. The agent’s background service writes temporary log files to a directory structure that matches the Logedrut IOC’s expected file path or naming convention (e.g., C:\ProgramData\Temp\agent_logs\).
falconctl.exe or cb.exe and the file path contains \ProgramData\Temp\agent_logs\.CI/CD Pipeline Artifact Staging: A DevOps pipeline (e.g., Jenkins or Azure DevOps) stages build artifacts in a shared network drive or local temp folder before deployment. The staging process creates a temporary executable or script with a name or hash that coincidentally matches a Logedrut IOC, particularly if the pipeline uses a generic naming convention like build_output.exe.
java.exe (Jenkins) or agent.exe (Azure DevOps) and the file path contains \workspace\ or \artifacts\.Database Maintenance Scripts: A DBA runs a scheduled maintenance script (
