Inside Suning’s Fight Against Online Scalpers: How Tech Teams Cracked Coupon‑Snatching Software

In recent years, as internet technology has advanced, the traditional “scalper” group has gradually moved from offline to online, with “network scalpers” becoming increasingly active.

Network scalpers are those who, not for normal consumption, snap up large numbers of discounted goods or coupons and resell them at higher prices. They often develop or use specialized software, renting or selling it, which, despite differing from traditional scalpers, shares the same profit‑driven motive and harms consumers, merchants, and e‑commerce platforms, disrupting fair shopping environments.

Recently, Suning’s technology risk‑control team successfully assisted the Nanjing Public Security Bureau in cracking a case involving the creation and sale of scalper software. The criminal gang, composed of high‑level computer professionals, spent over a year developing an “coupon‑snatching” tool for Suning, rented it out, and earned more than a hundred thousand yuan.

This illegal activity not only prevents users from obtaining coupons, undermining a fair shopping environment, but also generates massive bot traffic that can overload servers and cause greater losses.

According to the risk‑control team, their human‑machine identification system first detected abnormal behavior data. By correlating request IPs and device information, they traced clues, purchased the scalper software for reverse analysis, infiltrated the perpetrators’ QQ groups as undercover buyers, gathered real‑time updates, and continuously upgraded security strategies. All evidence was handed over to the police, leading to the gang’s arrest.

The joint operation demonstrates Suning’s technical capability in solving coupon‑snatching and bulk‑buying risks, helping merchants address problems they could not solve alone, protecting consumer interests, and maintaining a healthy shopping environment.

Suning has long deployed a comprehensive set of technical defenses against network scalpers, such as automated scripts that bypass sliding‑captcha challenges in emulators, and fingerprint‑recognition technology that can identify over 99% of existing emulators.

There is no permanent solution; continuous innovation is essential because scalpers thrive on change. In addition to anti‑scalper measures, Suning leverages risk‑data models and labeling systems to prevent malicious stock hoarding, fake transactions, flash‑sale abuse, and bot‑driven coupon grabbing, thereby creating a fair and orderly trading environment and enhancing user experience.
