On November 1, 2023, the London-based architecture and design firm Stanton Williams appeared on the leak site operated by the Black Basta ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the company’s network. The disclosure does not specify the volume or exact types of documents taken, nor does it list any individual customer or employee records. Anyone whose personal information, contracts, or correspondence passed through Stanton Williams could be affected.

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.

Primary Disclosure Details

The Black Basta leak site entry for Stanton Williams states that data was stolen and is now published after the firm did not meet the group’s demands. The posting, hosted on the onion address http://stniiomyjliimcgkvdszvgen3eaaoz55hreqqx6o77yvmpwt7gklffqd.onion/?id=STANTONWILLIAMS, includes a sample of the allegedly stolen material but does not quantify the total number of files or name specific data categories such as client personally identifiable information. Public trackers such as ransomware.live mirrored the listing on the same date. The notification does not mention any encryption of systems still in place or provide a ransom deadline, which is typical once a victim is moved to the public leak page.

Why This Matters for You and Your Family

When a design studio like Stanton Williams is breached, the exposed internal files can contain contracts, correspondence, planning documents, and contact details for clients, contractors, and staff. Personal addresses, phone numbers, email accounts, and project-related identifiers frequently sit inside such archives. If your home, business premises, or family project was handled by the firm, your details may now sit in a publicly downloadable torrent. This creates immediate risks of identity theft, phishing campaigns tailored to your property or renovation history, and unwanted targeting by scammers who blend real project knowledge with social-engineering lures.

Doxxing and Identity-Chain Risks

Leaked internal files often link professional identities to personal ones. An architect’s email signature, a client’s mobile number on a briefing sheet, or a child’s name on a school-extension project can become the first node in a doxxing chain. Threat actors cross-reference these fragments with credential leaks from other breaches, gaming accounts, or social-media handles. The result is a map that ties your real-world address to online personas. Credential leaks like this one cascade into account takeovers that can reach family members, including children’s gaming profiles that reuse the same password or recovery email. Once the chain begins, privacy evaporates quickly.

Black Basta’s Known Track Record

Public reporting attributes the first appearance of Black Basta to early 2022. The group rapidly established a double-extortion model: encrypt victim systems and threaten to publish stolen data if ransom is not paid. Notable prior victims include large manufacturers, healthcare providers, and professional-services firms across North America, Europe, and Australia. Their typical playbook involves initial access through compromised remote-desktop credentials or phishing, followed by lateral movement, data exfiltration over several days, and deployment of their custom ransomware. After exfiltration they wait a short period before publishing samples on their leak site, aiming to pressure victims into private negotiation. The exact tactics used against Stanton Williams remain unknown, but the outcome matches the group’s established pattern.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup of exposed records.
  • Rotate any password you ever used at stantonwilliams.com or in correspondence with the firm, and enable 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same addresses and recovery details.
  • Let remediation specialists handle takedown requests for any personal documents or contact details that surface on data-broker or extortion sites.

The incident underscores that even specialist design firms hold sensitive threads of everyday life. Acting promptly on the credentials and contact details now circulating can limit how far those threads unravel. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes 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.
