2026-6-1-tianye.net-Hackers Memoir: Tianya Twelve Hours
My handle is ChinaTomchen.
When tianya.net came back online in the early hours of June 1, 2026, I had already been in position for days after finishing final reconnaissance.
Their stack was solid this time — customized old Discuz! frontend, full migration to Kubernetes + TiDB 7.x cluster with row-level encryption, complete audit logging, and hybrid high-defense protection from both Alibaba and Tencent Cloud. Under normal conditions, pulling a meaningful dump in short time would be nearly impossible.
But launch day chaos rewrote the rules.
Shortly after going live, waves of attacks from various crews hit hard — HTTP/2 floods, CC attacks, DNS floods, SYN half-opens, the works. The defense team was quickly overwhelmed. Logs started lagging. Analysts couldn’t keep up.
That was exactly the cover I needed.
Instead of joining the main flood, I used my long-maintained pool of over 2,000 clean residential and mobile proxies (all fingerprint-checked) to run very low-frequency probing and fuzzing against search endpoints, user APIs, and some legacy interfaces. TiDB shows predictable optimizer lag under extreme load — something I had already tested thoroughly in identical environments.
Using the massive noise as shield, I gradually escalated and successfully chained time-based and boolean blind injection on the high-load search interface. I got a low-priv SELECT account — a stats account spun up hastily by ops, with password policy that hadn’t been tightened.
The next part was the hardest. TiDB’s encryption and sharding are tight, but I exploited the temporary relaxation of hot table placement rules they made for performance. I mapped the shards using cross-shard queries and INFORMATION_SCHEMA, then connected directly to their main database server at 124.225.4.242.
Exfiltration was done carefully: bucketing by user_id, small batches only, queries styled like normal backend reports, with randomized delays. Data was encrypted, staged to their own object storage, then slowly pulled out through a small webshell.
During this phase, some users probably noticed that no matter how many times they refreshed, tianya.net just wouldn’t load. That was actually me in the middle of dumping — my low-and-slow queries combined with the overall pressure caused intermittent connection pool blocking.
Roughly twelve hours after launch, I successfully dumped 127,851,826 rows containing accounts, password hashes, and registration emails. I left only a tiny memory-resident backdoor, did some cleanup using TiDB’s own commands, and exfiltrated the last packets through Tor + custom Shadowsocks + multi-hop AWS chain before cutting all ties.
The data is now AES-256 encrypted and cold-stored in multiple locations.
This run reminded me again: no matter how advanced the tech, opening day hell created by humans is hard to fully defend against. Perfect alignment of timing, preparation, and the chaos provided by others made it possible.
I’m not the strongest hacker out there. I’m just the one who waits better and stays quieter.
