Real-world example
How this scam plays out in practice
Based on reported patterns. Names and details are illustrative.
The setup
Jessica, 33, a remote workers, encountered what appeared to be a legitimate wifi and hotspot scams situation while using WiFi network. An attacker on the same open WiFi network uses ARP spoofing or similar techniques to position themselves between the victim and the router.
Step 2
What happened next was calculated: All of the victim's traffic passes through the attacker's device, where credentials and session tokens can be captured.
Step 3
The pressure escalated quickly: The attacker may also inject malicious JavaScript or redirect DNS queries to phishing sites.
The outcome

The lesson
