A significant data leak, allegedly totaling 500GB, has reportedly impacted Messer Group China, a major player in the industrial gas sector. The purported breach, which is claimed to have occurred in May 2025, includes a wide array of sensitive data and remote desktop protocol (RDP) permissions.
Messer Group is a globally recognized industrial gas company with a substantial presence in China. As a leading manufacturer and supplier of industrial, medical, and specialty gases, their operations are critical to various industries, including manufacturing, healthcare, and environmental technology. The company’s Chinese arm, mesergroup.cn, is a vital part of its international network, serving a vast client base within the region.
The leaked data allegedly comprises diverse file types, including spreadsheets (XLSX, CSV), documents (Word, PDF), multimedia files (MP4, MP3, JPEG), and virtual machine disk images (MDF, VMDK). The inclusion of RDP permissions in the compromised data raises particular concerns, as it could potentially grant unauthorized access to internal systems.
As of now, Messer Group has not publicly commented on the alleged incident. Information regarding the breach has reportedly appeared on an online forum, with claims of samples and proof of possession being available. The alleged perpetrators are also reportedly offering escrow services for interested buyers.
This developing situation highlights the ongoing cybersecurity challenges faced by large enterprises, particularly those with extensive digital footprints in critical industrial sectors.
