Boarding Concept listed on malas ransomware leak site

• Ransomware group: malas
• Sector: Hospitality
• Announcement date: April 9, 2023

The hospitality organization Boarding Concept has been listed on the leak site of the ransomware group known as malas. The threat actor announced the inclusion of the organization on April 9, 2023, claiming that an attack was carried out against the organization's systems.

The claimed attack and method

According to the announcement made by the malas group, the incident occurred on April 9, 2023. The threat actor claims to have successfully carried out an attack against the systems belonging to Boarding Concept. The group alleges that the attack leveraged a specific vulnerability within the Zimbra software to gain access.

In the context of modern cyber threats, the exploitation of vulnerabilities in widely used software, such as email or collaboration platforms, is a common tactic used by ransomware groups. When attackers identify and exploit unpatched vulnerabilities, they can often gain an initial foothold within a corporate network. Once inside, these actors may attempt to escalate privileges or move laterally through the infrastructure to identify sensitive assets.

Details regarding the alleged data breach

While the group has publicly listed the organization on their leak site, no details regarding the nature of the alleged leaked data have been provided. The listing does not specify the types of files, the volume of information, or the specific categories of data that the group claims to have exfiltrated from the organization.

The listing names no specific data types.

Risks and organizational implications

The announcement by the malas group may pose significant risks to the operational continuity of Boarding Concept. The reported use of Zimbra vulnerabilities could indicate the potential for unauthorized access to internal networks by the attackers, which can disrupt standard business processes and service delivery.

If a data breach has indeed occurred, it could lead to the exposure of customer personal information. Such exposure often results in secondary risks, including identity theft or the launch of targeted phishing attacks against the affected individuals. These types of follow-on attacks are common when personal data is leaked, as threat actors use the stolen information to gain further trust from victims.

Publicly available information regarding the malas group remains limited. For organizations facing similar threats, it is often advisable to fulfill necessary notifications under relevant data protection regulations and to conduct thorough security audits of their systems to identify and remediate vulnerabilities.

General defensive considerations

To mitigate the risks associated with ransomware and data exfiltration, organizations typically focus on several defensive pillars. Maintaining a robust patch management program is essential to address vulnerabilities in software like Zimbra before they can be exploited. Furthermore, implementing strict network segmentation can help prevent attackers from moving laterally through the network if an initial compromise occurs.

Monitoring for unusual network activity and implementing strong access controls are also standard practices for maintaining security posture. In the event of a suspected breach, organizations often rely on incident response plans to manage the technical and regulatory consequences of the event.
