I am having an issue with my Wyze cam v3 sending several thousand DNS requests each second. This is causing problems with my Wi-Fi and my security gateway’s CPU. Sending several thousand packets like this causes ~60% CPU consumption to process all of the suspicious traffic. This limits bandwidth for…

Seeing this on my end as well. I have two v3’s and sporadically throughout the day they both start spamming thousands of DNS requests to google.com . I use NextDNS which makes this easy to monitor. The top domains in the past 6 hours is really telling: [image]

5 is fine. Try hundreds per second… That’s what I’m seeing: [image] I thought the firmware update resolved it, however I was wrong; the issue resumed the next day. This causes the pihole to take a couple minutes to boot up to resize the FTL Queries. Wyze really needs to fix this, there is NO…

Maybe this is part of Chairman Xi’s efforts to DDOS DNS servers and Wyze is their agent. ;<)

Same experience here with my pihole. Currently 2.5 million requests over 9 hours. My log over 24 hours is usually around 10-15mb, currently after 9 hours its 234mb. Trying to grep out and wc to verify down to the exact number but I think its (pihole) locked it up again since there’s so many entri…

Should also mention for those who have theories, I did notice that several of my SD card video’s didn’t upload fully to the cloud. Only about the first frame. My pihole puts you on the no no list after making too many queries so I’m guessing that is what’s happening. But I’m going to go enjoy the…

Yup. this continues. Here’s a screen grab of my PiHole’s activity this morning… [2022-06-17_14-05-27] That grey bar represents 1000 DNS inquiries in a period of ten minutes from a single WyzeCam. That’s 16.7 per second – before the PiHole said “enough” and halted the activity! (For comparison,…

It’s ridiculous. It’s still unplugged and if I get some time I’m going to solder on some header pins and try to download the firmware. Then just grep for Google.com and see what classes and functions are doing with it. Needless to say I’m no longer a Wyze customer.

Taking a look a one of the routers’ outbound connection s this morning we see the massive number of DNS inquiries continues, Below follows an image of one of the WyzeCams making repeated contacts with Google DNS at 8.8.8.8. How can Wyze fins this to be acceptable? This is just one of many simil…

[image] In the past six hours, I have logged 164k requests from my cameras. Totally unnecessary.

It was fixed months ago. And it was never possible for a remote attack using that quite minor vulnerability. Users were safe. Wyze just sat on it way too long.
