It's a full-scale PII breach . Attackers are bypassing simple password defenses to access your "crown jewels"—your entire customer database. This is a decision-grade playbook for CISOs, IT Directors, and compliance officers. Your customer PII (Personally Identifiable Information) is sitting in a SaaS app, protected by one password.

Emergency Guide: Table of Contents
Chapter 1: The Race Against Time — Oracle Releases Emergency Patch
Oracle has released an emergency, out-of-band security patch for the critical unauthenticated RCE vulnerability in E-Business Suite that we have been tracking as **CVE-2025-61882**. This is the moment security teams have been waiting for, but it is not a moment for relief. It is the start of a race.
As we warned in our **previous alert**, a public Proof-of-Concept (PoC) exploit for this vulnerability is already in the wild. This means that attackers have had a head start. Automated, mass-exploitation campaigns are already in full swing. Every unpatched, internet-facing Oracle EBS instance is a target. Your patching window is not measured in days; it is measured in hours.
Chapter 2: The Defender's Playbook — The 3-Step Emergency Patching Protocol
Follow this protocol precisely to secure your systems.
Step 1: APPLY THE ORACLE PATCH IMMEDIATELY
This is your highest and most urgent priority. Navigate to the Oracle Critical Patch Update advisory page and apply the patch for **CVE-2025-61882** to all of your affected Oracle E-Business Suite instances. This is a non-negotiable, all-hands-on-deck emergency task.
Step 2: VERIFY The Patch Application
After the patch is deployed and services are restarted, you must verify that the fix was successful. Use your organization's vulnerability scanner to run an authenticated scan against the patched systems to confirm that CVE-2025-61882 is no longer detected. Do not assume the patch worked; verify it.
Step 3: REMOVE Temporary Mitigations
If you followed our previous guidance and took your EBS instances offline or implemented strict firewall blocks, you can now, *after* the patch has been verified, begin the process of carefully bringing the services back online.
Chapter 3: The 'Assume Breach' Mandate — Hunting for Compromise
Patching closes the door. It does **not** kick out an intruder who is already inside. Given that this vulnerability was actively exploited as a zero-day, you must operate under the assumption that your systems were breached before you could apply the patch. The next critical phase is to proactively hunt for Indicators of Compromise (IOCs).
The #1 Hunt: Look for Anomalous Child Processes
A successful RCE will result in the core Oracle/IAS process spawning a shell. This is the "golden signal" of compromise. Use your **EDR platform** to immediately run this query across all your EBS servers:
ParentProcess IN ('ebs_process', 'ias_process', 'frmweb.exe')
AND ProcessName IN ('cmd.exe', 'powershell.exe', '/bin/bash', '/bin/sh')
Any result from this query is a critical alert and a sign of a successful takeover that requires immediate incident response. For a full guide on this methodology, see our **Threat Hunting Hypothesis Playbook**.
Detect Post-Exploitation Activity: An EDR/XDR platform is your essential safety net for post-breach investigation. A solution like **Kaspersky's XDR** can detect the attacker's actions *after* the initial exploit, such as lateral movement, credential dumping, and data exfiltration.
Chapter 4: The Strategic Response — Moving Beyond Reactive Patching
This entire incident, from zero-day to public exploit to emergency patch, is a perfect illustration of the modern threat landscape. A reactive, "patch-on-Tuesday" mindset is no longer sufficient. A resilient security program must be built on a foundation of **Zero Trust** and proactive defense. Your critical, internet-facing applications must be isolated in micro-segments, your user and administrative access must be protected with the strongest possible MFA, and you must have the deep, behavioral visibility to detect an attacker even when they are using a brand new, unknown exploit.
