Philippine Nuclear and Naval Targets Hit by Suspected Chinese Operator

Suspected Chinese-speaking operator breached Philippine nuclear research and naval supplier systems via ownCloud CVE-2023-49103 and WordPress CVE-2024-28000.

Hunt.io found an exposed staging server containing custom Python scripts, logs, and stolen data documenting intrusions against a Philippine nuclear research body and a marine engineering company serving the Philippine Navy. The actor exploited an ownCloud authentication bypass (CVE-2023-49103) using empty-secret pre-signed WebDAV URLs and a LiteSpeed Cache plugin flaw (CVE-2024-28000) to gain WordPress admin access, also guessing passwords against XML-RPC with rockyou.txt. Roughly 9 GB was referenced as stolen from the nuclear agency, including reactor databases, radiation-safety records, and staff passport data; Simplified Chinese labels suggest a Chinese-speaking operator.

ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

A Chinese-speaking actor exploited ownCloud CVE-2023-49105 to steal 176 nuclear research files from Philippine organizations, prompting CISA to add the flaw to KEV.

CISA added CVE-2023-49105 (CVSS 9.8), an ownCloud WebDAV API authentication bypass fixed in version 10.13.1, to the KEV catalog after Hunt.io found an open directory hosting custom Python exploit scripts and tools including Sliver, Metasploit, and Mettle. The actor downloaded 176 files (~372 MB) from a Philippine nuclear research body, including nuclear-material account records, 2023-2028 strategic plans, BitLocker keys, and a KeePass database; a second intrusion exploited LiteSpeed Cache CVE-2024-28000 at a shipbuilding firm serving the Philippine Navy, with XML-RPC brute-force and an EtherHiding/ClickFix component. FCEB agencies must patch by August 30, 2026. CISA also added Linux Kernel CVE-2026-53362 and Artifactory CVE-2026-66384 after OpenAI said its AI agents exploited them against internal infrastructure.
