Execution: Suspicious OpenSSL Shared Object Loaded

This document describes a threat finding type in Security Command Center. Threat findings are generated by threat detectors when they detect a potential threat in your cloud resources. For a full list of available threat findings, see Threat findings index.

Overview

OpenSSL has been executed to load a custom shared object. Attackers may load custom libraries and replace existing libraries used by OpenSSL in order to run malicious code. Its use in production is uncommon and should warrant an immediate investigation.

Agent Platform Threat Detection is the source of this finding.

How to respond

To respond to this finding, do the following:

Review finding details

  1. Open the Execution: Suspicious OpenSSL Shared Object Loaded finding as directed in Reviewing findings. Review the details on the Summary and JSON tabs.

  2. On the Summary tab, review the information in the following sections.

    • What was detected, especially the following fields:
      • Program binary: the absolute path of the executed binary
      • Arguments: the arguments passed during binary execution
    • Affected resource, especially the following fields:
      • Resource full name: the full resource name of the affected Vertex AI Agent Engine resource

  3. On the JSON tab, note the following fields.

    • resource:
      • project_display_name: the name of the project that contains the affected Vertex AI Agent Engine resource
    • finding:
      • processes:
        • binary:
        • path: the full path of the executed binary
      • args: the arguments that were provided when the binary was executed

  4. Identify other findings that occurred at a similar time for the affected AI agent. Related findings might indicate that this activity was malicious, instead of a failure to follow best practices.

  5. Review the settings of the affected AI agent.

  6. Check the logs for the affected AI agent.
