In the bustling tech hub of Silicon Valley, cybersecurity investigator Elena Martinez found herself deep into a late-night investigation at Horizon Tech Solutions on July 7, 2025. The company had reported sporadic network disruptions affecting their research team ' s access to critical project files. Elena, working under the cover of a maintenance window from midnight to 3 AM PDT, began monitoring the internal network, focusing on a subnet reserved for the R & D department. She noticed a pattern of failed connection attempts logged just before each disruption, with multiple hosts reporting temporary IP address conflicts. Suspecting foul play, Elena deployed a discreet test to simulate an internal threat scenario. Shortly afterward, several workstations began showing unfamiliar gateway settings and redirected users to misleading login portals during routine access attempts. Despite these anomalies, no security alerts were triggered.
What type of attack technique did Elena most likely simulate?
