Introduction:
In the rapidly evolving landscape of cloud security, the line between consumer and creator is blurring. When a managed security provider like O3 Cyber sits down with Google’s Threat Intelligence PM and the cofounder of VirusTotal in Málaga, it signals a shift: field experience is now directly influencing enterprise product roadmaps. With the recent finalization of the Wiz acquisition, understanding how to integrate platforms like Google SecOps, Wiz, and Mandiant is no longer optional—it is the new standard for defending cloud infrastructure at scale.
Learning Objectives:
- Understand the strategic importance of integrating Wiz with Google SecOps and Google Threat Intelligence.
- Learn how to leverage VirusTotal and Google Threat Intelligence for proactive threat hunting.
- Explore practical steps to harden multi-cloud environments using field-tested configurations.
You Should Know:
- Integrating Wiz with Google SecOps for Unified Visibility
The acquisition of Wiz by Google is a game-changer for cloud security posture management (CSPM). O3 Cyber’s deep experience with both platforms highlights a critical workflow: using Wiz to identify vulnerabilities and misconfigurations, then feeding that context directly into Google SecOps for automated response.
Step‑by‑step guide: Setting up Wiz to Google SecOps Integration
This integration allows you to send Wiz issues as findings to Google SecOps (formerly Chronicle Siem) for correlation with other security telemetry.
Note: Requires administrative access to both platforms.
1. In Wiz:
- Navigate to Settings > Integrations.
- Click Add Integration and select Google SecOps.
- Provide a name for the integration.
- Upload the Google Service Account JSON key file provided by your Google SecOps environment. This key grants Wiz permission to ingest findings.
- Configure the Issue Age (e.g., send only issues created in the last 24 hours) and Severity filter (e.g., CRITICAL, HIGH).
- Click Save.
2. In Google SecOps:
- Go to SIEM Settings > Feeds.
- Ensure the Wiz feed is active. You may need to verify the ingestion of the `wiz_issues` log type.
- Create a new Rule to alert on specific high-severity Wiz findings, such as “publicly exposed storage bucket.”
- Use the UDM Search to confirm data is flowing:
metadata.vendor_name="Wiz".
2. Operationalizing Google Threat Intelligence with VirusTotal
The meeting between O3 Cyber and Google Threat Intelligence (GTI) underscores the need for actionable intel. GTI, powered by Mandiant and VirusTotal, provides context on adversaries. Security teams must move beyond just viewing IOCs to understanding the “who and why.”
Step‑by‑step guide: Enriching Alerts with VirusTotal API
This demonstrates how to automate the enrichment of suspicious IPs or hashes found in your environment using the VirusTotal API (a core component of GTI).
1. Get your API Key:
- Log in to your VirusTotal account.
- Navigate to your API Key section. Copy the key.
2. Linux Command Line Enrichment:
Use `curl` to query an IP address.
!/bin/bash
API_KEY="YOUR_VT_API_KEY"
IP_ADDRESS="8.8.8.8" Replace with suspicious IP
curl --request GET \
--url "https://www.virustotal.com/api/v3/ip_addresses/${IP_ADDRESS}" \
--header "x-apikey: ${API_KEY}" | jq '.data.attributes.last_analysis_stats'
This returns a JSON object showing how many vendors detected the IP as malicious. The `jq` command filters the output for readability.
3. Windows PowerShell Enrichment:
For a Windows environment, use PowerShell to achieve the same.
$API_KEY = "YOUR_VT_API_KEY"
$IP_ADDRESS = "8.8.8.8"
$URI = "https://www.virustotal.com/api/v3/ip_addresses/$IP_ADDRESS"
$HEADERS = @{ "x-apikey" = $API_KEY }
try {
$RESPONSE = Invoke-RestMethod -Uri $URI -Method Get -Headers $HEADERS
$RESPONSE.data.attributes.last_analysis_stats | ConvertTo-Json
} catch {
Write-Host "Error: $_"
}
3. Hardening Cloud Environments Based on Field Experience
O3 Cyber’s philosophy of staying “close to the metal” means translating on-the-ground attacks into preventative measures. A common finding in the field is overly permissive Identity and Access Management (IAM) roles.
Step‑by‑step guide: Remediating a Risky IAM Role in Google Cloud (SCC)
Using Google Cloud’s Security Command Center (SCC) findings, you can automatically remediate a publicly exposed Compute Engine instance.
1. Identify the finding in SCC:
- Go to Google Cloud Console > Security > Security Command Center > Findings.
- Filter for “Public bucket/VM” or high-severity IAM issues.
2. Remediate via gcloud CLI:
- First, list the current IAM policy for the offending resource (e.g., a VM instance).
gcloud compute instances get-iam-policy INSTANCE_NAME --zone=ZONE
- Remove the offending binding (e.g., `allUsers` or
allAuthenticatedUsers). - Create a JSON policy file that excludes the public access, then set it.
Dump current policy to file gcloud compute instances get-iam-policy INSTANCE_NAME --zone=ZONE --format=json > policy.json Manually edit policy.json to remove the "allUsers" binding using nano or vim nano policy.json Set the updated policy gcloud compute instances set-iam-policy INSTANCE_NAME policy.json --zone=ZONE
4. Automating Threat Detection with Mandiant Services
With Mandiant experts now tightly integrated into the Google Cloud ecosystem, defenders can automate the hunting of advanced threats. This involves setting up detections based on the latest Mandiant threat intelligence.
Step‑by‑step guide: Creating a YARA-L Rule in Google SecOps
Create a detection rule for a newly discovered malware hash provided by Mandiant.
- In Google SecOps, go to Detections > Rules.
2. Click Add New Rule.
- Use the YARA-L 2.0 syntax to match on process hash.
“`bash-l
rule detect_malicious_hash {
meta:
author = “SecurityTeam”
description = “Detects execution of known bad hash from Mandiant Intel”
severity = “HIGH”
events:
$e.metadata.event_type = “PROCESS_LAUNCH”
$e.principal.process.file.sha256 = “e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855”
condition:
$e
}
4. Set the Alerting options to send a notification to a security channel (e.g., Slack or PagerDuty) and Save the rule.

<li>Aligning Culture and Roadmap for Security Impact
Beyond the technical, O3 Cyber emphasizes that retreats and alignment are crucial. In practical terms, this means using Infrastructure as Code (IaC) to enforce security standards defined during strategic planning sessions.</li>
</ol>
Step‑by‑step guide: Enforcing a Security Baseline with Terraform
Ensure every new cloud project adheres to the security roadmap by enforcing a mandatory label and VPC configuration.
<ol>
<li>Define a Terraform policy using the `google_project` resource.
```bash
resource "google_project" "security_baseline_project" {
name = "Secure Project"
project_id = "secure-proj-123"
folder_id = "123456789"</li>
</ol>
labels = {
"security-tier" = "high"
"managed-by" = "o3-cyber"
}
}
resource "google_compute_network" "vpc_network" {
name = "secure-vpc"
project = google_project.security_baseline_project.project_id
auto_create_subnetworks = false
delete_default_routes_on_create = true
}
2. Run a `terraform plan` to review changes.
- Apply the configuration to enforce the new standard, ensuring every deployed asset has the proper security context and network isolation.
What Undercode Say:
- Key Takeaway 1: The Wiz acquisition is not just about tool consolidation; it is a strategic move to embed deep CSPM capabilities directly into the cloud fabric, allowing for real-time, automated remediation of misconfigurations at the source.
- Key Takeaway 2: Effective cloud defense requires a feedback loop. Field experience from providers like O3 Cyber is being used to shape Google’s product roadmap, ensuring that threat intelligence and security tools address real-world attack paths rather than theoretical vulnerabilities.
This direct line of communication between practitioners and platform engineers represents a maturation of the industry. We are moving away from bolt-on security tools toward integrated, intelligent platforms. The focus on “culture” and “roadmap” in a technical field validates that security is as much about alignment and process as it is about code. By leveraging APIs and automation based on shared intelligence, defenders can finally operate at the same speed as the cloud itself.
Prediction:
Over the next 12 months, we will see a surge in “unified cloud security platforms” where CSPM, CIEM, and CWP are indistinguishable from the cloud provider’s native console. The integration of Wiz into Google Cloud will force competitors to build or buy similar deep-integration capabilities. Security operations will pivot from “detecting” misconfigurations to “preventing” them through policy-as-code that is enforced at the infrastructure layer before a single line of workload code is ever deployed.
