• Ransomware group: Babuk2
• Country: Japan
• Sector: Retail & E-Commerce
• Announcement date: March 22, 2025

Babuk2 claims to have leaked jp-property.com data

The Babuk2 ransomware group has published a claim on its leak site involving the Japanese organization jp-property.com. According to the announcement, the threat actors have released approximately 50 GB of data that they claim belongs to the company. This incident follows a pattern common in modern cyberattacks where threat actors utilize leak sites to pressure organizations by making stolen information publicly accessible.

Ransomware groups often employ a tactic known as double extortion. In these scenarios, the attackers do not merely encrypt an organization's systems to disrupt operations; they also exfiltrate sensitive data before the encryption phase. The threat of releasing this data on a public leak site serves as additional leverage to compel the victim to pay a ransom. While the specific ransom demand for this incident has not been disclosed, the act of publishing data is a hallmark of this extortion strategy.

Details of the alleged breach

The Babuk2 group claims to have targeted jp-property.com on March 22, 2025. The group asserts that they successfully exfiltrated corporate data during this operation. The announcement specifies that the leaked information is provided in CSV format, a common format for structured database exports.

The threat actor has provided specific counts regarding the types of records they claim to have stolen. According to the group's announcement, the leaked data includes:

• 171,333 'enq_submit' records
• 2,532,543 'member' records
• 17,325 'property' records

The specific categories of data identified in the leak include member data, property records, and inquiry forms. The scale of the breach, if the claims are accurate, suggests a significant volume of information has been moved from the organization's environment to the attackers' control.
