Black and Gray Market Threats and Countermeasures in the Residential Services Industry

01 Black‑Gray Market Overview

The residential services industry comprises upstream new‑home developers and second‑hand owners, and downstream buyers and tenants, with platforms ranging from information aggregation to fully integrated services like Beike.

Industry Black‑Gray Market

Traditional gray‑market threats are categorized into traffic, device, account, business, and data layers, while industry‑specific threats focus on fake listings, private deals, data theft, agent performance fraud, and external‑internal chain interactions.

Typical Scenario 1: Fake C‑End Registrations

Criminals obtain SIM cards and use black‑market tools to create fake accounts, which are sold to agents for fraudulent viewings or to “wool‑pull” participants for marketing incentives, enabling downstream profit extraction.

Typical Scenario 2: Web Crawlers

At least 62 commercial crawlers target Beike data, priced low (199‑455 CNY/year), facilitating bulk extraction of listings and personal information, harming platform revenue and user privacy.

02 Intelligence System Construction

The intelligence workflow includes collection (city reports, external monitoring, internal white‑hat data), traceability processing (account, device, business behavior analysis), and operational use (law‑enforcement collaboration, risk‑control product iteration).

03 Traceability Capability Building

A "weapon library" of seized devices, software, and IP resources supports automated tracing; the technical stack processes logs into rule‑based alerts, storing results in audit and risk platforms for targeted investigations.

04 Counter‑measure and Evidence Collection

The five‑stage response comprises traceability, analysis (identifying legal violations), reporting to authorities, forensic evidence gathering, and coordinated arrests with on‑site tool confiscation.

05 Q&A

Questions addressed the prevalence of broadband usage by black‑market actors and the current lack of blockchain integration in traceability incentives.
