RansomHub claims to have stolen data from 310 tempering

The RansomHub ransomware group has listed approximately 65 GB of data on their leak site, which they claim belongs to 310 tempering. This announcement, made on February 15, 2025, follows a claimed attack date of February 6, 2025. The group alleges that they successfully gained access to the organization's internal systems and extracted a significant volume of sensitive information, totaling 117,393 files.

Ransomware leak sites serve as a platform for cybercriminal groups to exert pressure on their victims. In these scenarios, the threat actors often employ a tactic known as double extortion. This method involves not only encrypting the victim's systems to disrupt operations but also stealing sensitive data beforehand. The group then threatens to publish this stolen information on their public leak site if the ransom demands are not met, thereby increasing the pressure on the organization through the threat of public exposure and regulatory scrutiny.

The alleged cyberattack and data exfiltration

According to the claims made by the RansomHub group, they conducted a cyberattack against 310 tempering and obtained access to the company's data. The group is using the publication of these files on their leak site as a method to exert pressure on the organization. By making the data available to the public, the attackers aim to maximize the impact of the breach and coerce the victim into compliance.

The content of the alleged leak is extensive, involving various types of corporate and financial documentation. The group claims that the stolen information includes a wide array of internal files that could compromise the organization's operational privacy. The specific types of data mentioned in the listing include:

• Accounting records
• Financial statements
• Customer invoices
• Tax documents
• Payment information

The inclusion of such diverse data types suggests a broad infiltration of the company's digital environment, targeting both financial and administrative sectors of the business.

About 310 tempering

310 tempering is a United States-based manufacturing company specializing in glass tempering and processing services. The company produces custom glass solutions for various industrial and commercial applications, serving a range of sectors that require specialized glass products.

Impact and assessment of the breach

This breach may compromise the confidentiality of the organization's financial operations and customer relationships. The inclusion of invoices and payment details in the leaked data could expose customers to secondary risks such as identity theft and targeted phishing attacks. When sensitive financial and customer information is leaked, it often leads to a wave of fraudulent activities where attackers use the stolen details to impersonate legitimate business entities or individuals.

Given that the organization is based in the US, legal proceedings and administrative sanctions under relevant state laws and federal data protection regulations may be initiated. Organizations operating in highly regulated environments must navigate complex legal landscapes following a data breach, often facing investigations into their security posture and compliance with privacy standards.

Considering the past activities of the RansomHub group, it is assessed that the group employs double-extortion tactics and that the publication of this data may lead to significant corporate reputational damage. It is worth noting that the group's action, reported to have ceased operations in early 2025, may be viewed as an attempt to liquidate the data in their possession.

For organizations in the manufacturing sector, such incidents highlight the importance of robust cybersecurity frameworks. Defensive steps often include implementing multi-factor authentication, maintaining offline backups, and conducting regular security audits to identify vulnerabilities. Protecting the integrity of supply chain data and customer information remains a critical priority for manufacturers to prevent the long-term consequences of data exfiltration and reputational loss.
