"Wu Gong, several abnormal accounts suddenly appeared in our game for no apparent reason. They're getting huge quest rewards, so there's obviously a problem. Operations has checked the data several times, and even rolling back the servers didn't help—they keep appearing like crazy. We can only lock those accounts out, but new ones still keep popping up... Could your development side do some debugging and see what's causing this?"
"Oh, got it. Nothing's wrong in our test environment. It might be a hacker attack, then this is troublesome. We'll need a new firewall." A half-bald middle-aged programmer replied listlessly.
"Then take another look. If it doesn't work, we'll migrate to XX@'s servers. Their firewall is better."
"Alright, we'll check again."
Abnormal account data was actually very easy to detect.
Even abnormal save data in a single-player game could be discovered immediately and locked down, let alone an online game account that constantly interacted with the server and underwent data verification.
If your gold or experience suddenly increased, there would be a limit on how much gold and experience you could obtain each day, because the quests you could complete were limited. That would immediately trigger the anomaly detection system.
Ancient games did not have such things, but now this was a basic module built into game programs.
An anomaly detection system was easy to make and did not consume much processing power.
All it took was verifying the save data.

Using a developer account, he made a round through the game.
Several hundred alt accounts had appeared in the game, chattering away.
