Site Design Group Listed by AiLock Ransomware Group

On May 2, 2026, the Chicago-based landscape architecture and urban design firm Site Design Group Ltd. appeared on the leak site of the AiLock ransomware group, with attackers claiming to have exfiltrated internal files during a ransomware incident.

Confirmed Facts from Reporting

Public reporting indicates that Site Design Group, which specializes in landscape architecture and urban design, was listed on the AiLock ransomware leak portal. The entry states that internal files were taken during the attack. No specific count of affected individuals has been disclosed, and the precise volume or nature of the stolen files remains unclear from available information. The listing appeared on the group’s public leak site, a common tactic used to pressure victims into paying a ransom demand.

Internal files were the primary data type referenced. Ransomware.live, a tracker that monitors such incidents, documented the listing on May 2, 2026. As is typical in these cases, the attackers likely first gained access to the company’s network, encrypted systems, and then threatened to publish or sell the stolen data if their demands were not met.

Why This Matters for You and Your Family

When a company like Site Design Group is hit, the information inside its files can easily include details about clients, vendors, partners, or employees. If your name, address, email, phone number, or payment records appear in those documents, the breach now puts you at risk. Criminals do not limit themselves to corporate targets; they look for anything that can be used against ordinary people and their families.

Stolen client records or project documents often contain home addresses, contact information, and sometimes even details about family members involved in residential projects. Once that information leaves the company’s control, it can surface on dark-web markets, forums, or ransomware leak sites where anyone can download it. For many families, this is the moment when identity theft, phishing attempts, or unwanted contact begins.

The Doxxing and Identity-Chain Risks

Ransomware incidents like this frequently feed larger doxxing chains. A single leaked email or phone number can be linked to your social-media accounts, online shopping profiles, and even your children’s gaming usernames. Attackers automate the process, building a complete picture that lets them impersonate you, reset passwords on other services, or harass your family directly.

Credential leaks cascade into account takeovers. If an employee reused a work password on a personal account, or if client files contained shared project logins, the exposure can spread quickly. Gaming accounts belonging to children are especially vulnerable because they often share the same email domain or recovery phone number listed in the breached corporate files. This creates a direct path from a business ransomware attack to personal doxxing and harassment.

AiLock Group’s Known Track Record

Public reporting attributes the AiLock ransomware group with activity that emerged in recent years. The group follows a double-extortion playbook: they encrypt victim systems and simultaneously exfiltrate data, then demand payment to prevent publication. Notable prior victims have included companies across various sectors, though specific names change frequently as new incidents are claimed. Their typical approach involves initial access through common vulnerabilities or phishing, followed by data theft, encryption, and public shaming on their leak site when victims do not pay by the stated deadline.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this incident may have exposed.
• Rotate any password used at Site Design Group or related services anywhere it has been reused, and switch on two-factor authentication through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next leak that touches your family is caught and addressed in hours, not months.
• Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts, which often chain back to the same addresses or recovery details now at risk.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.

The incident shows that even specialized design firms can become unwilling gateways to personal data exposure.
