TheNovosti is an Eastern European-origin threat actor cluster associated with large-scale malicious advertising and social-engineering operations that coerce users into subscribing to abusive browser push notifications. The actor is known for using cloaking and traffic-distribution infrastructure, including Keitaro, to selectively present benign content to intermediaries while redirecting intended victims to deceptive landing pages. A characteristic tradecraft element is the use of fake partially loaded or broken-page templates designed to trick users into enabling push notifications, after which the actor can deliver scams, unwanted content, or further malicious redirects at scale. TheNovosti has been noted for extremely high domain churn, reportedly rotating thousands of domains per week at peak, indicating mature operational automation and strong resilience against takedowns. The actor’s activity aligns with financially motivated malvertising and scam operations emphasizing defense evasion, large-scale traffic acquisition, and persistent victim re-engagement through browser notification abuse.
