• Announcement date: February 1, 2026

Interlock claims to have breached Odyssey Academy

The Interlock ransomware group has listed data allegedly belonging to Odyssey Academy on its leak site. According to the announcement made on February 1, 2026, the group claims that the data became publicly available due to the negligent attitude of the school's staff and administration. This incident marks a significant potential breach for the educational institution, as the group alleges that various confidential documents and financial reports have been compromised.

Ransomware groups often utilize leak sites to host stolen information as part of a pressure tactic. In many modern cyberattacks, threat actors employ a strategy known as double extortion. In this scenario, the attackers do not just encrypt the victim's systems to disrupt operations; they also exfiltrate sensitive data. If the victim refuses to pay the ransom to decrypt their files, the attackers threaten to release the stolen data publicly to cause maximum reputational and legal damage. This method increases the pressure on organizations to comply with ransom demands.

Details of the alleged data leak

The information provided by the group suggests a wide range of compromised files. Based on the screenshots associated with the claim, the leaked content includes Active Directory user lists, device configuration files in XML format, network reports, and various system folders. The group alleges that the breach involves several critical categories of information that could pose a risk to the institution and its community.

The specific types of data allegedly involved in the leak include:

• Student data
• Staff data
• Financial reports
• Network configuration files

While the specific volume of the data or the total file count has not been disclosed, the presence of network configuration files and system folders suggests a deep level of access into the organization's digital infrastructure.

About Odyssey Academy

Odyssey Academy is a free public charter school operating in the United States. The institution provides educational services with the goal of preparing students for adulthood.

Impact and risk assessment

This leak may increase the risk of identity theft and targeted phishing attacks for students and staff at Odyssey Academy. When personal identifiers are leaked, malicious actors can use them to craft highly convincing social engineering campaigns. Furthermore, the disclosure of financial data may lead to secondary fraud attempts targeting the institution or its stakeholders.

Educational institutions are frequent targets for cybercriminals due to the high volume of sensitive personal information they manage. Such leaks targeting educational institutions could lead to legal consequences under FERPA and state-level data privacy regulations in the US. Organizations in this sector must navigate complex regulatory landscapes to protect student privacy and maintain compliance with federal and state laws.

While information about the Interlock group is limited, the incident highlights the ongoing threat posed by ransomware actors. To mitigate such risks, organizations typically focus on defensive measures such as implementing multi-factor authentication, maintaining regular offline backups, and conducting regular security awareness training for staff to prevent the negligence that attackers claim leads to successful breaches. The disclosure of this information may have negative impacts on the institution's operational continuity and reputation management.
