Compromised sites are a recurring enforcement target, and Baidu warns site owners around periods when attacks spike.
What attackers do
- Inject hidden pages targeting gambling or adult queries.
- Add redirects that fire only for search visitors.
- Modify the site to serve different content to the crawler.
Recovery
Clean completely, close the entry point, submit the injected URLs as dead links, then request review. A partial clean followed by re-infection extends the penalty.

Как мы это применяем
Injected pages are usually invisible to the owner because they are only served to the crawler or to search visitors. We check the index for pages the client did not publish, which is where the problem shows up first.
