Город Кафе listed on malas leak site

The threat group known as malas has listed the organization Город Кафе on its leak site. This announcement, which appeared on April 9, 2023, indicates a potential data breach involving the hospitality entity. The threat actor claims to have conducted an operation against the systems of the organization, marking a new entry on the group's public platform.

The alleged attack and method

According to the announcement made by the malas group, the group claims to have carried out an operation targeting the systems of Город Кафе. The threat actor specifically stated in the announcement that this action was carried out by exploiting a Zimbra vulnerability. This method of entry highlights a common tactic used by cybercriminals, where known vulnerabilities in widely used software are leveraged to gain unauthorized access to organizational networks.

Ransomware groups often utilize such vulnerabilities to establish a foothold within a network. Once access is gained, these actors typically move laterally through the environment to identify sensitive assets. The use of specific software vulnerabilities, such as those found in email or collaboration suites like Zimbra, remains a significant vector for initial access in modern cyberattacks.

Details regarding the leaked data

Despite the listing on the leak site, there is a lack of specific information regarding the contents of the alleged breach. The provided screenshot associated with the announcement lists the name of the organization, but it does not contain specific information regarding the data content. No details regarding the content of the leaked or threatened data have been shared by the group.

The listing names no specific data types or quantities. Specifically, there is no information available regarding:

• The total size of the claimed data
• The specific file count
• The nature of the data content
• The amount of the ransom demand

In many double extortion schemes, threat actors claim to have exfiltrated sensitive information to pressure victims into paying a ransom. While the group has claimed an operation took place, the absence of detailed data samples or file lists is a common occurrence in the early stages of a leak site announcement.

Impact and potential risks

Information about the malas group remains limited, making it difficult to assess their full operational scope. However, the alleged action against the systems of Город Кафе may result in the exposure of customer data or operational information. Given the sector in which the organization operates, potential disruptions in compliance with data protection regulations may be observed.

The alleged vulnerability may have led to the organization's digital assets becoming accessible to unauthorized parties. Such unauthorized access poses several significant risks to an organization and its stakeholders. Secondary risks may include identity theft or targeted phishing attacks, where stolen information is used to deceive individuals or further penetrate the corporate network.

For organizations operating in the hospitality sector, maintaining robust defensive postures is critical. This includes regular patching of all software to mitigate vulnerabilities like the one mentioned in this incident. Organizations should also focus on implementing strong access controls and continuous monitoring to detect unauthorized lateral movement within their networks. Proactive measures such as network segmentation and employee training on phishing awareness are also vital components of a comprehensive cybersecurity strategy to protect digital assets and sensitive customer information.
