About this episode

The episode discusses how spam filters influenced the development of adversarial machine learning through various evasion attacks and data poisoning techniques used by spammers.

This story was originally published on HackerNoon at: https://hackernoon.com/how-spam-filters-shaped-the-field-of-adversarial-ml . Evasion attacks and data poisoning let spammers bypass filters, turning the early-2000s inbox into a lab that shaped adversarial machine learning.

The 2000s spam arms race was an early stress test for adversarial ML. Spammers learned to manipulate inputs without seeing the model, close feedback loops with tracking pixels, and poison training data with as little as 1% corrupted samples. Every one of those attacks has a modern descendant in today's AI systems. The lesson the spam arms race exposed still holds: accuracy alone is not a sufficient measure of performance…
