G-B57JWL4PY2

This isn't just theoretical. Since the crack was released, incident response teams have noted three primary malicious activities:

Attackers are bypassing authentication to change the router’s DNS settings. Instead of legitimate ISP DNS, the router points to malicious servers that redirect banking traffic to phishing sites. Because the change happens at the router level, devices on the LAN cannot override it locally.

The flaw exists in the way RouterOS processes session creation requests. By setting a specific session ID and certain flags, the service incorrectly assumes a valid authenticated session already exists.

Pseudo-code example of exploit logic:

packet = craft_winbox_packet(session_id=0xdeadbeef, flag=auth_bypass)  
send_to_port(target_ip, 8291, packet)  
receive_admin_access()
