Kuaishou responds to the flooding of pornographic content in live streaming rooms

Event process
On December 22, around 10 PM, a large-scale incident of the dissemination of violating content occurred on the Kuaishou platform, with multiple live streaming rooms featuring obscene videos, vulgar performances, and other content, some of which had view counts approaching 100,000. The platform's review mechanism failed to intercept the content in a timely manner, resulting in the continued spread of violating content for about 1.5 hours. At 12:15 AM on the 23rd, Kuaishou urgently closed the live streaming function and banned relevant accounts, gradually restoring normal operations by 12:45 AM.

Platform response
Kuaishou officially announced in a statement early on the 23rd that this incident was due to attacks from black and gray market activities. The system has been urgently repaired and the police have been notified, and the situation has been reported to the relevant authorities. The platform emphasized its firm stance against illegal content and is cooperating with the public security organs in the investigation.

Analysis of Attack Features and Causes
1. Automated attack methods
Black and gray industries achieve the rapid release and dissemination of illegal content through bulk registration of zombie accounts and exploiting vulnerabilities in live streaming interfaces, completely bypassing real-name authentication and manual review processes. The traditional manual review mechanism is unable to cope with high-frequency attacks due to its lag, resulting in "bans not keeping up with new additions."

2. Asymmetric offense and defense capabilities
Qihoo 360 security experts point out that the black and gray industry has entered the era of "automated attacks", while platforms still rely on manual defenses, leading to a significant efficiency gap between the two. This attack exposed the vulnerabilities in the risk control system of the platform when responding to extreme security incidents.

Subsequent impacts and warnings
- The event caused Kuaishou's stock price to plummet over 4% in the early trading session the next day, resulting in a market value evaporating by approximately 16.4 billion HKD.
- Industry insiders urge companies to strengthen "internal and external defense", not only upgrading external attack defense technology but also reinforcing internal permission control to prevent "insiders" or permission vulnerabilities from being exploited.

Summary
This incident highlights the shortcomings of live streaming platforms in defending against automated black and gray market attacks, and once again rings the alarm for an upgrade in cybersecurity. Although Kuaishou has taken emergency measures, how to build a more efficient automated defense system remains a core issue that it needs to address in the future.
