I just tried this, i took some strings about Falun Gong and the Tianmen thing from the chinese wikipedia and put them into my SSH server banner. The connection attempts from the Tencent AS ceased completely, but now they come from Russia, Lithuania and Iran instead.
Whoa, that's fascinating. So their botnet runs in multiple regions and will auto-switch if one has problems. Makes sense. Seems a bit strange to use China as the primary, though. Unless of course the attacker is based in China? Of the countries you mentioned Lithuania seems a much better choice. They have excellent pipes to EU and North America, and there's no firewall to deal with
