The leaked data reportedly includes over 1.1 million phone numbers, seller names, property details, and listing URLs. While much of the data is publicly available, the aggregation of phone numbers and seller information could facilitate targeted scams.","Threat actor claims to leak 4M French real estate listings, including 1.1M phone numbers.","Data4M+ listings Price4 forum points CountryFrance ActorChimeraZ ▣Post details TargetLeboncoin Immobilier (aggregated real-estate listings) CountryFrance SectorReal Estate \u002F Classifieds ClaimAggregated listing dataset leaked (source teased) Data~4M listings (13 portals); 1.1M phone numbers ObservedJun 8, 2026 Price4 forum points (paywall) ActorChimeraZ !Allegedly exposed ~4M property listings (claimed) 1.1M+ phone numbers Seller \u002F lister names Listing prices & property details Postal codes & listing locations Ad URLs & references Data from 13 French property portals Listing photo \u002F media links ◱Screenshot Screenshot 1 Redacted preview ⚠Potential impact If genuine, an aggregated set of 4 million listings with around 1.1 million phone numbers, seller names, property values, and locations would be a strong resource for spam, vishing, and property-related scams targeting both sellers and buyers across France. Much of the listing content is public ad data, but the bulk phone-and-name aggregation is the sensitive part. Because the actor frames the source as an upstream third party, the true compromised entity may differ from the portals named, and the figures are unconfirmed. iStatus Unverified A data sample and per-site line counts were posted to an underground forum, with downloads behind a small points paywall; the sample records, seller contact details, and download links are not reproduced here. The actor teased that the source of the compromise would be revealed later. The claim has not been independently confirmed, and the named portals have not addressed it.
