Quote:A sophisticated browser locker campaign that ran on high-profile pages, like Microsoft Edge's home or popular tech sites, was deactivated this week after in-depth research was published.
 
The actors behind it used a compromised an ad content supplier for top-tier distribution and combined targeted traffic filtering with steganography.
 
This mix allowed the operation to survive for at least two years, bringing victims to a tech support scam page and threat researchers to a dead end as they scratched their heads about how the redirect to the fake malware reporting page happened.
