TL;DR: A campaign spanning WordPress, Gitea and ZyXEL exploitation since May 2026 led to more than 18,000 government records stolen and 996 switches exfiltrated, GreyNoise reports. Exposed services and reusable credentials can turn one foothold into backend collection when containment fails.
Editorial analysis by NHI Mgmt Group, based on content published by GreyNoise: “Open Season on Kapibala: Attacker Steals Over 18,000 Government Records Through WordPress Exploitation”.
By the numbers:
- GreyNoise reports successful exploitation of 996 ZyXEL GS1900 switches across 48 countries.
- GreyNoise says at least 49 organizations across 29 countries were affected by the WordPress wp2shell chain.
- GreyNoise notes that 564 of the 996 ZyXEL victims had factory default credentials.
Key questions
Q: Why do default credentials and rooted device access create outsized risk?
A: Default access collapses the attacker’s work from discovery into immediate control.
Q: What signs indicate an intrusion has moved from exploitation to collection?
A: Look for dumped admin accounts, masquerading user creation, webshell-driven reconnaissance, local ZIP staging, unusual PowerShell or script activity, and outbound retrieval from temporary paths.
Q: What breaks when exposed services are exploitable and credentials are still reusable?
A: The attacker does not need a single perfect exploit path.
Practitioner guidance
- Map internet-facing assets to live exposure Compare external scanning results with current patch and service inventories so that reachable WordPress, switch and management interfaces are validated against actual exploitability.
- Hunt for webshells and staging paths Look for unusual downloads, local archive creation, web-reachable temporary files and remote collector activity that indicate the attacker has moved beyond the initial exploit.
- Revoke and rotate exposed credentials Treat admin tables, readable config files, device root credentials and backend database secrets as incident-grade exposure if they appear in compromised systems.
Bottom line: This campaign shows that exploitation rarely stays at the perimeter once attackers can reuse credentials, webshells or default device access.

Internet scanning is now an identity and access governance problem, not just a perimeter problem. GreyNoise’s reporting shows that the earliest stage of compromise is often just the opening move before credential theft, account masquerade and backend access. That means exposure management, access control and privileged identity hygiene have to be governed together, not as separate programmes. Practitioners should treat externally reachable services as identity-bearing attack surfaces.
A question worth separating out:
Q: Should defenders prioritise patching or credential governance first after a campaign like this?
A: Both matter, but credential governance becomes urgent once attackers are already inside. If exposed credentials, default logins or backend secrets are present, patching alone may only slow the next attempt. The decisive question is whether a compromise can still pivot from one service into another without fresh authentication.
