In 2016, cybersecurity firm White Ops uncovered a massive ad fraud operation: Methbot.
A network of over 570,000 bots simulated real users across 6,000 spoofed domains and 250,000+ fake URLs.
These bots mimicked human behavior, scrolling, clicking, even logging in, to trick video ad platforms into thinking real people were watching premium ads.
At its peak,
Methbot was generating 200 to 300 million fake video views per day.
Advertisers were unknowingly paying up to $5 million per day for impressions that never reached a single human.
Much of the fraud was routed through major ad exchanges, including Google’s programmatic ecosystem.
Advertisers buying through Google Display & Video 360 or Display campaigns in Google Ads were impacted without knowing it.
The total estimated losses ranged between $180 million and $1 billion.
Methbot wasn’t a script. It was a full-scale ad tech impersonation engine exposing how easily spend can be siphoned off by well-disguised fraud.
