‘War Dialing’ Tool Exposes Zoom’s Password Problems
War dialing refers to "using a simple programs that dial consecutive phone numbers looking for a modem. Users often bypass a site 's network security schemes by allowing their computers to receive incoming telephone calls. The user enables a modem upon leaving work and then is able to dial in from home and use the corporate network. Attackers use war dialing programs to locate computers allowing incoming calls.
Numbers are dialed systematically and the answering tones are assessed. Just as with a port scanner, available A War Dialing assessment looks for answering resources and then the attacker can then attempt to attack the service in order to gain access. HackLabs' War Dialing Penetration Test follows documented security testing methodologies which include:. We produce a comprehensive report covering the approach, the techniques utilised, and the vulnerabilities identified. The detailed report contains recommendations to ensure that your systems are secured against the attack. But these phone-based vulnerabilities represent the easy way into many network environments still to this day. The best firewall cannot protect against rogue modems operating on critical servers or user desktops. Best Practice recommends that each organisation perform a Penetration Test as part of their regular Security Program in order to ensure the security of their telecom security defenses.

As the Coronavirus pandemic continues to force people to work from home, countless companies are now holding daily meetings using videoconferencing services from Zoom. According to its makers, zWarDial can find on average meetings per hour, and has a success rate of around 14 percent. Each Zoom conference call is assigned a Meeting ID that consists of 9 to 11 digits. Naturally, hackers have figured out they can simply guess or automate the guessing of random IDs within that space of digits. Security experts at Check Point Research did exactly that last summer , and found they were able to predict approximately four percent of randomly generated Meeting IDs. The Check Point researchers said enabling passwords on each meeting was the only thing that prevented them from randomly finding a meeting. Zoom responded by saying it was enabling passwords by default in all future scheduled meetings. Zoom also said it would block repeated attempts to scan for meeting IDs, and that it would no longer automatically indicate if a meeting ID was valid or invalid. Nevertheless, the incidence of Zoombombing has skyrocketed over the past few weeks, even prompting an alert by the FBI on how to secure meetings against eavesdroppers and mischief-makers.
