Moscone Center Listed by quantum Ransomware Group

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

Moscone Center was listed on Quantum's leak site. Quantum claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Moscone Center Listed by quantum Ransomware Group

On September 1, 2022, the Moscone Center in San Francisco appeared on the leak site operated by the Quantum ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the large meeting and exhibition facility founded in 1981. The disclosure does not quantify how many people may be affected, nor does it list the specific types of documents taken.

You can’t unleak data. You can take away what it’s worth.
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.

Details in the Leak-Site Listing

The Quantum leak site entry states that Moscone Center suffered a ransomware intrusion and that attackers successfully removed internal files before encryption. No victim count, no sample documents, and no ransom amount appear in the posting. The facility, which hosts major conventions and events in downtown San Francisco, has not released its own public notification detailing the breach. Public reporting on similar Quantum listings indicates that when negotiations fail the group publishes a subset of stolen data as proof and leverage.

Why This Matters for You and Your Family

Even though the Moscone Center is a business venue, the people whose information ends up in stolen internal files are ordinary attendees, vendors, contractors, and nearby residents. Event registration lists, vendor contracts, employee records, and facility maintenance documents routinely contain names, addresses, dates of birth, Social Security numbers, and payment details. Once those records leave the organization’s control, they can surface months or years later in identity-theft schemes that target you and your family. The disclosure indicates the data was taken in 2022; you may still be unaware that your information is circulating.

Doxxing and Identity-Chain Risks

Stolen internal files often create long doxxing chains. An email address from a Moscone Center vendor contract can link to your social-media accounts, child’s school forms, or gaming usernames. Attackers combine these fragments with data from other breaches to build complete identity profiles. Credential leaks like this one frequently cascade into account takeovers on personal email, banking, and gaming platforms. Children’s gaming accounts tied to a parent’s address or reused password are especially vulnerable once the household connection is mapped.

Quantum Ransomware Group Track Record

Public reporting attributes the Quantum ransomware group’s emergence to late 2021. The gang has targeted healthcare providers, manufacturers, and public venues, typically gaining initial access through phishing or exploited remote-desktop services. After exfiltration they deploy ransomware, then pivot to extortion by threatening to publish sensitive files. Their playbook relies on short negotiation windows followed by gradual data leaks on their dedicated site when victims refuse payment. The Moscone Center listing fits this established pattern.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours rather than months.
  • Rotate any password you used for Moscone Center event registrations or vendor portals anywhere it has been reused, and switch to 2FA through an authenticator app instead of SMS.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that can chain back to the same address or leaked documents.
  • Let remediation specialists manage takedown requests for any exposed personal records found on data-broker and extortion sites.

The incident underscores that convention-center data breaches can expose everyday families years after the initial intrusion. Starting proactive defense now limits how far attackers can travel down the identity chain created by this and future leaks. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full 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.
