Xinos Construction Corp and its accounting group targeted by N0n ransomware group

• Ransomware group: N0n
• Country: United States
• Sector: Manufacturing
• Announcement date: October 16, 2026

The threat actor known as N0n has listed data allegedly belonging to Xinos Construction Corp and its accounting group on their leak site. This announcement, made on October 16, 2026, indicates that the organization is facing a significant data exposure incident involving sensitive information.

The claims made by the N0n group

The N0n group has published a leak announcement claiming to have obtained data from Xinos Construction Corp and its accounting group. According to the group's claims, the institution's financial and employee data is being threatened with public disclosure. The group indicates that these files may be released if the ransom demand is not met.

The group is operating via a method known as double extortion. In such scenarios, threat actors do not merely encrypt an organization's systems to disrupt operations; they also exfiltrate sensitive data. The threat of leaking this stolen information to the public or to competitors serves as additional leverage to pressure the victim into paying a ransom. While the specific ransom demand has not been disclosed, the threat of public disclosure remains the primary driver for the attackers.

The alleged compromised data

The data allegedly compromised in this incident is extensive and includes highly sensitive personal and financial information. The contents of the breach, as claimed by the attackers, include the following:

• Employee HR records
• Social Security numbers
• Tax returns
• Client financial records
• Court records

Beyond these categories, the group claims to have access to specific documents such as employee W-2 forms, quarterly payroll tax filings, 2024 partnership tax returns with schedules K-1, a QuickBooks Enterprise archive, court and city hearing records, the complete 2024 New York State sales tax audit file, as well as client financial records and employee personal files.

About Xinos Construction Corp

Xinos Construction Corp is a construction and general contracting company based in College Point, New York. The company specializes in roofing, waterproofing, building restoration, and renovation services.

Impact and industry considerations

This incident may increase the risk of identity theft and fraud for the institution's employees and clients. Given the nature of the leaked data and its US-based origin, legal repercussions under HIPAA or relevant state data protection laws could potentially arise. The exposure of financial records and tax filings may create opportunities for secondary attacks or targeted phishing campaigns.

Information regarding the N0n group is limited. The actions of such groups can lead to significant reputational damage and operational disruptions if the data is fully disclosed. For organizations in the construction and contracting sector, such breaches highlight the necessity of robust data protection frameworks. Protecting sensitive client financial records and employee personal files is critical to maintaining trust and avoiding legal liabilities.

To mitigate the risks associated with such attacks, organizations typically focus on defensive strategies such as implementing multi-factor authentication, maintaining regular offline backups, and conducting regular security awareness training for employees to recognize phishing attempts. Furthermore, securing financial software and ensuring strict access controls over tax and payroll documents can reduce the likelihood of successful data exfiltration.
