Site Design Group Listed by AiLock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Site Design Group was listed by the AiLock ransomware group on May 02, 2026, with internal files reported as exfiltrated. Anyone connected to the organisation should check whether their information was exposed and take appropriate protective steps.
Breaking down the breach
Public reporting on the incident remains limited to the group’s leak-site entry. The entry claims that files were taken from Site Design Group Ltd., but provides no further technical details on how access was obtained or when the intrusion occurred. The number of records or files involved has not been disclosed, and Site Design Group has not issued a public statement confirming or describing the event.
Inside AiLock
AiLock is a ransomware operation that maintains a public leak site where it lists organizations it claims to have targeted. The group typically follows a double-extortion pattern: encrypting systems and also removing data before demanding payment. Listings on its site represent the group’s assertions rather than independently verified incidents. AiLock has appeared in multiple prior public reports involving other organizations, though each case requires separate confirmation.
About Site Design Group
Site Design Group Ltd. is a Chicago-based company that provides landscape architecture and urban design services. Firms in this sector routinely manage project documentation, client correspondence, site plans, and internal administrative records. A compromise at such an organization can expose materials related to both commercial clients and public-sector projects.
What data was at risk
The only detail released is that internal files were allegedly exfiltrated. The precise categories of information contained in those files have not been disclosed. Organizations of this type commonly hold client contact details, project specifications, financial records, and employee information, but it is not confirmed whether any of these categories were among the files taken.
Why it matters
Even without confirmed counts, the exposure of internal files from a design and planning firm can affect ongoing projects and client relationships. Individuals or entities named in project documents may face secondary risks if their contact or business information appears in the exfiltrated material. For the organization, the incident adds to the operational and reputational costs typically associated with ransomware events.
If your data was in this claimed breach
Monitor accounts for unusual activity and consider changing passwords for any services linked to the organization. Enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address against known breach data to check for appearances in public listings. Organizations should follow established incident-response procedures and consult legal or cybersecurity professionals for tailored guidance.

Publicly posted by ailock — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
