Cybersecurity researchers have revealed a sophisticated campaign attributed to a financially motivated threat actor known as CyberXero, which claims to have stolen over 628,000 records from various Ukrainian entities. This operation, which has been active since at least July 2026, employs a dual approach that combines traditional offensive tools like Cobalt Strike with an AI orchestration layer powered by Anthropic’s Claude Code, targeting WordPress sites, e-commerce platforms, and critical infrastructure.
According to a report by SOCRadar, the campaign operates two distinct pipelines: a global automated attack against WordPress and e-commerce platforms, and a more targeted effort focused on Ukrainian energy and critical infrastructure. The global campaign exploits known vulnerabilities, including wp2shell (CVE-2026-63030 and CVE-2026-60137) and CVE-2026-4815, an SQL injection flaw affecting the Support Board WordPress plugin, to gain unauthorized access to WordPress sites.
Details of the CyberXero Campaign
The operation has reportedly led to confirmed data exfiltration from four Ukrainian organizations, with additional compromises noted in Poland, China, and the Netherlands. SOCRadar discovered the campaign after identifying an exposed directory at “46.21.250[.]135,” which contained the threat actor’s live working directory, including AI session logs, exploitation toolkits, and exfiltrated victim data. The campaign remains ongoing.
The automated pipeline is designed to maximize access volume across e-commerce and WordPress platforms, while the targeted pipeline focuses on deep reconnaissance and manual exploitation of Ukrainian critical infrastructure, including a heating provider in Kharkiv. Analysis of the exposed directory revealed that a single automated execution scanned 4,708 targets, confirming access to 429 WordPress administration panels and deploying 32 web shells within a 61-second timeframe.
AI Integration in CyberXero’s Operations
CyberXero’s use of AI is notable, as it employs Claude Code in two independent stages of the attack lifecycle. The first stage involves a cluster of 51 specialized agents for scanning, exploit chaining, reconnaissance, and post-exploitation, all running on the attacker’s primary workstation. The second stage connects PentAGI, an open-source AI agent for autonomous penetration testing, to Cobalt Strike via an API for payload generation and execution.
To circumvent model refusals, the threat actor has utilized context-engineering techniques, framing their requests as authorized penetration tests. SOCRadar noted that the AI model’s safety controls operate on session context, allowing the actor to reopen fresh sessions to bypass refusals for certain tasks.
In addition to targeting WordPress and e-commerce platforms, the campaign has also exploited exposed Redis servers, resulting in breaches of two Chinese entities. Organizations using WordPress, Magento, or PrestaShop, or exposing Redis to the internet, are advised to check for unauthorized WordPress administrators and unexpected entries in their systems.
Implications and Recommendations
The CyberXero campaign exemplifies a growing trend where opportunistic attacks are automated for volume while simultaneously conducting targeted operations against critical infrastructure. SOCRadar emphasizes the need for organizations to bolster their defenses against such multifaceted threats, particularly those operating in vulnerable sectors.
As the campaign continues, organizations are urged to remain vigilant and implement robust security measures to protect against unauthorized access and data breaches. The convergence of AI in cybercrime operations poses significant challenges, necessitating a proactive approach to cybersecurity.
