Chapter 1: The Falcon Has Landed — CrowdStrike Confirms Widespread Attacks

This is a CODE RED alert, amplifying a critical threat advisory from CrowdStrike. Following our previous warnings on the **public exploit for CVE-2025-22998** and the **NCSC’s critical warning**, CrowdStrike’s OverWatch threat hunting teams have now confirmed our worst fears: multiple, distinct threat actors have operationalized the exploit and are conducting mass, automated attacks against any and all internet-facing Oracle E-Business Suite instances. The time for deliberation is over. The threat is no longer theoretical; it is a live, global campaign.

Chapter 2: The Adversary’s Goal — From Foothold to Enterprise Ransom

According to CrowdStrike’s intelligence, the activity they are observing is primarily consistent with **Initial Access Brokers (IABs)**. These are the specialist vanguard of the ransomware ecosystem.

The IAB Playbook:

1. **Mass Exploitation:** They use automated scanners to find and exploit vulnerable EBS servers at scale.
2. **Foothold Establishment:** Upon successful RCE, they deploy a simple webshell or a lightweight backdoor to establish persistence.
3. **Access Brokerage:** They do not deploy ransomware themselves. Instead, they package this initial access and sell it on dark web forums to top-tier ransomware groups like LockBit or BlackCat.

The critical takeaway is this: a breach by one of these actors should be considered the **direct precursor to a full-blown, enterprise-wide ransomware attack.**

Chapter 3: The Defender’s Playbook — CrowdStrike’s Recommended Actions

The guidance from the security community is unanimous and absolute. With a “no-patch” zero-day under active mass exploitation, there are only two priorities: containment and hunting.

1. IMMEDIATE NETWORK CONTAINMENT

This is the only 100% effective mitigation. Your Oracle EBS web interface ports **must not be accessible from the public internet.** Use your perimeter firewall or WAF to block all access from untrusted networks immediately.

2. HUNT FOR COMPROMISE (Assume Breach)

You must assume your systems have been targeted. Use your **EDR platform** to hunt for the “golden signal” of compromise: the core Oracle process spawning a shell.

ParentProcess IN ('ebs_process', 'ias_process', 'frmweb.exe') AND ProcessName IN ('cmd.exe', 'powershell.exe', '/bin/bash', '/bin/sh')

Chapter 4: The Strategic Takeaway — The Clock Has Run Out

This is the culmination of the entire vulnerability lifecycle, and it proves a critical strategic point: the window between exploit publication and mass exploitation is now effectively zero. A reactive, “wait for the patch” security posture is a guaranteed recipe for a breach. CISOs must build and fund a security program that can act on early-stage threat intelligence and operate on an “assume breach” footing.

Your ability to survive this event is not dependent on when Oracle releases a patch. It is dependent on whether you have a resilient, **Zero Trust** architecture to contain the blast radius and an advanced **XDR platform** to detect the attacker’s TTPs inside your network.

 Detect the Post-Exploitation Phase: An XDR platform is your essential safety net. A solution like **Kaspersky’s XDR** provides the deep behavioral visibility needed to detect the attacker’s lateral movement and credential dumping, giving you a chance to stop the impending ransomware attack.
