Bad Packets LLC said that they had detected an initial scan in their honeypots, “it’s interesting to find the source is physically closer to the affected Livebox ADSL modems than say a threat actor in another country. This could allow them to connect to the WiFi network (SSID) if they were near one of the modems indexed by their scans.”

With the most affected devices uses the default passwords “admin/admin” and not having any custom passwords configured. The poorly configured devices allows attackers to view the phone number, MAC address of the connected devices.

An attacker could use this attack vector to extract connected device phone numbers which pose a very serious threat to user’s. By making the victim’s visiting the malicious site attackers can setup auto dialing profile on the victim’s modem which call’s attacker number without user interaction.
