The 8base group claims a breach of Tetrosyl Group Limited

The threat actor known as 8base has listed Tetrosyl Group Limited on its dedicated leak site, claiming to have successfully exfiltrated the company's data. This announcement, made on February 7, 2024, marks a significant development in the ongoing threat landscape facing the manufacturing sector. According to the claims made by the group, the breach occurred on the same day the announcement was posted.

The 8base group alleges that it has compromised the company's internal data and has obtained various documents from the organization's servers. By listing the company on their leak site, the group is employing a double-extortion tactic. This method involves not only encrypting a victim's systems to disrupt operations but also threatening to publish the allegedly stolen data on public forums to pressure the organization into paying a ransom.

Alleged compromised data types

The claims made by the threat actor suggest that a wide variety of sensitive information has been targeted. Based on the information provided by the group, the following types of documents and files are allegedly compromised:

• Invoices
• Receipts
• Accounting documents
• Personal data
• Certificates
• Employment contracts
• Confidentiality agreements
• Personal files

The breadth of the data types mentioned suggests a deep penetration into the company's administrative and human resources systems. While the specific volume of the data and the exact number of files involved have not been disclosed by the group, the nature of the documents points toward sensitive corporate and personal information.

Impact and industry implications

For organizations in the manufacturing and automotive sectors, such incidents highlight the necessity of robust security postures.
