Lamashtu claims data breach against Becker Logistik

The Lamashtu ransomware group has listed data on its leak site, claiming it belongs to the German logistics company Becker Logistik. This announcement, made on September 30, 2026, suggests a targeted operation against the transportation firm. While the group has posted the information on their platform, the claim remains an assertion by the threat actor.

According to the claims made by the Lamashtu group, the incident involved the theft of approximately 50 GB of data, consisting of 45,000 files. The threat actor states that these files were obtained from the internal network of Becker Logistik. The group claims that the stolen data covers a broad historical period, spanning from 2020 to 2026. This timeframe suggests that the compromised information encompasses several years of administrative operations and business activities.

The group's decision to list the data on a public leak site is a tactic often used to exert pressure on an organization. By making the stolen information available to the public, ransomware actors aim to coerce the victim into meeting their demands. This method of operation is a hallmark of modern cyber extortion campaigns.

Details of the claimed data theft

The data allegedly exfiltrated by the Lamashtu group is extensive and covers various aspects of the company's operations. The information reportedly includes a wide range of sensitive files that could impact both the company and its stakeholders. The specific categories of data mentioned in the claim include:

• Human resources records
• Payroll information
• Accounting documents
• Fleet management data
• Legal proceedings
• Real estate information
• Banking relationships
• Employee personnel files
• Driver records
• Tax documentation
• Vehicle registrations
• Financial correspondence
• Identity information
• VPN configuration files

The inclusion of sensitive files such as identity information, payroll, and banking relationships highlights the potential severity of the breach. Furthermore, the presence of VPN configuration files is particularly concerning for digital security, as such information can be leveraged for further unauthorized access.

Risk assessment and implications

The alleged leak of this data may increase the risk of identity theft and targeted phishing attacks for the organization's employees and business partners. Because the organization is based in Germany, the leaked data may be subject to GDPR regulations, which could potentially necessitate a formal data breach notification process. The exposure of corporate network configuration files and VPN credentials could trigger secondary attack risks against the company's digital infrastructure, potentially allowing attackers to regain access or move laterally through the network.

While information regarding the Lamashtu group is limited, it is a common practice for ransomware actors to use such data for double extortion. In a double extortion scenario, attackers not only encrypt the victim's data but also threaten to leak it publicly to maximize leverage. This approach places significant pressure on the organization's operational continuity and commercial reputation.

In such scenarios, organizations typically face complex challenges involving legal compliance, technical remediation, and reputation management. The potential for secondary attacks following the exposure of network configurations underscores the need for robust identity and access management and continuous monitoring of digital assets. The impact of such breaches can be felt across the entire supply chain, especially in the logistics sector where data sharing between partners is frequent.
