Hey Marvelous Cyber Knights Out There, Today We are going to talk about a bug that is found on Zoom An Application That no one can forget because of its terrible Privacy Policy Well Researches Found another bug that lets them eavesdrop on the conversations that users made and ultimately putting user’s data into risk, Well let’s delve into the details, In a recent study, security experts have dug up some concerning issues with AudioCodes desk phones and Zoom’s Zero Touch Provisioning (ZTP) feature. These problems could be a playground for bad actors to mess with your devices from afar.

“SySS security researcher “Moritz Abrell gave the lowdown, saying that sneaky outsiders could fully control AudioCodes desk phones and exploit Zoom’s ZTP for unauthorized access. The potential outcomes are pretty scary: listening in on your chats, getting into company networks, and even forming armies of compromised gadgets. The researchers dropped this bombshell at the Black Hat USA security conference. The trouble seems to start with Zoom’s ZTP. This tool lets IT folks set up VoIP gadgets in one swoop, making device management a breeze. It’s all done through a web server on the local network, giving out setups and updates. But hold on, there’s a hiccup. The way this works doesn’t put up much of a fight against hackers. There’s a missing checkpoint that could let them nab malicious firmware from a shady server.

On top of that, the experts found flaws in the security of AudioCodes VoIP desk phones. These phones team up with Zoom ZTP and have issues with their secret-handshake routines. These hiccups could spill the beans on private stuff like passwords and setup files. All this happens when the phones try to fetch their configurations from a redirect server. Now, imagine these vulnerabilities teaming up like a sneaky duo. Hackers could use both flaws to set off a chain reaction and plant dodgy firmware through Zoom’s ZTP. This means they could tap into devices from miles away. As Abrell puts it, this could become a big security headache since it’s a pretty scalable attack.

This news reminds us of a similar issue discovered about a year ago. The same cybersecurity gang found a weakness in Microsoft Teams Direct Routing. This flaw let fake messages pose as Microsoft and make unauthorized calls through people’s phones. Bottom line: These findings are a reminder that tech security is a big deal. It’s crucial for companies to stay sharp and fix weak spots. This way, we can keep our chats private and our gadgets in check.

So, there you have it — a scoop on the not-so-pleasant side of AudioCodes phones and Zoom’s ZTP. The deal is, these vulnerabilities can let the wrong folks take control of your devices from afar. That means snooping on your talks, messing with networks, and even building zombie armies of gadgets. It’s like the bad guys found a hidden backdoor. Remember, Zoom’s ZTP seems like a time-saver for tech whizzes, but it’s got a soft spot for attackers to sneak in. And those AudioCodes phones? They might spill the beans on passwords and more if hackers come knocking.

The fix? Well, it’s all about companies staying ahead in the security game. If they don’t patch these holes, the hackers sure won’t mind having a field day. So, keep your gadgets safe, your chats private, and let’s hope the tech world tightens those screws.
