high severity May 06, 2026 · 3 min read Unverified claim — what this is

WOHA Listed by lamashtu Ransomware Group

If you are a customer of Woha, here’s what is being claimed, and what it would mean for you.

WOHA is a renowned Singapore-based architectural practice founded in 1994 by Wong Mun Summ and Richard Hassell. The firm is globally recognized for its integration of environmental and social principles into high-density urban settings.

— from Lamashtu’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
WOHA Listed by lamashtu Ransomware Group

On May 6, 2026, the Singapore architectural firm WOHA appeared on the leak site of the ransomware group Lamashtu. The listing indicates that internal files were exfiltrated during a ransomware attack on the company, which was founded in 1994 and is known for integrating environmental and social considerations into urban design projects across Asia and beyond.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Reported Details of the Incident

Public reporting on the Lamashtu leak site shows that WOHA’s internal files were taken. The exact number of people whose information is contained in those files remains unknown. No specific deadline for payment has been publicly detailed in available reporting, though ransomware groups typically set short windows before full data publication.

The breach follows the group’s standard pattern of exfiltrating sensitive business documents before encrypting systems or threatening release. Industry research from sources such as DoxxScan™ continuous monitoring indicates that architectural and design firms increasingly appear in ransomware incidents because their project files often contain contracts, client personal data, employee records, and financial information.

Why This Matters for You and Your Family

When a firm like WOHA is breached, the exposed data can include names, addresses, contact details, identification numbers, and correspondence connected to clients, contractors, and employees. If you or any member of your family has worked with an architectural practice, lived in one of their developments, or been listed as a reference on a project document, your information may now sit in an attacker’s archive.

Personal data from such leaks frequently moves from initial sale on dark-web forums into broader identity theft operations. A single exposed email or phone number can link to your banking, government services, or children’s school records. For ordinary families this means higher risk of account takeovers, fraudulent loan applications in your name, or unwanted contact from scammers who already know details about where you live or work.

The Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one company’s files. Attackers map relationships between exposed records to build larger profiles. A leaked WOHA project document might list your home address alongside a family member’s email, a child’s name, or even login details for shared accounts. These connections create doxxing chains that let criminals target you across multiple platforms.

Credential leaks of this kind often cascade into gaming accounts. Usernames, emails, or passwords reused from a family member’s compromised work or school file can give attackers access to your child’s Roblox, Fortnite, or Steam profile. Once inside, they can harvest friends lists, payment methods, and chat history, extending the identity chain further.

Lamashtu’s Publicly Known Track Record

Public reporting attributes Lamashtu with emerging in late 2024. The group has claimed responsibility for attacks on healthcare providers, manufacturing companies, and professional services firms. Its typical playbook involves initial access through phishing or exploited remote desktop services, followed by exfiltration of documents, deployment of ransomware, and then dual extortion: demanding payment both to decrypt systems and to prevent publication of stolen data. Notable prior victims listed on ransomware tracking sites include mid-sized businesses whose client and employee records were later posted when negotiations failed.

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 WOHA leak may have exposed about you.
  • Rotate any password you used at WOHA or related professional services anywhere it has been reused, and switch on two-factor authentication through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next time your information surfaces you learn within hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become the next link in doxxing chains after credential leaks like this one.
  • Let DoxxScan remediation specialists handle takedown requests for any exposed personal records found on data broker sites or forums connected to the incident.

The WOHA breach is a reminder that even organizations you interact with only occasionally can become gateways to your family’s personal information. Taking concrete steps now limits how far attackers can travel along any identity chain created by this or future leaks. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage including children’s gaming accounts.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
