🚨 BREAKING: A Broadcom Wi-Fi bug lets anyone in range run code on routers without the password.
Quentin Kaiser showed it on Proximus, Orange Belgium and VOO routers and estimates ~1.5M in Belgium are exposed, none patched.
The bug dates to 2010. Broadcom won't assign a CVE.

@IntCyberDigest Unauthenticated RCE on Wi-Fi routers could allow an implant to spread itself in urban environments unnoticed. Incredibly irresponsible of Broadcom to refuse assigning a CVE

@IntCyberDigest 1.5m routers is an estimate, operators need exact affected firmware versions to check their exposure

@IntCyberDigest if you're in belgium with one of these: you can't flash an ISP box yourself, but you can switch its wifi off and put your own router behind it until they patch

@IntCyberDigest Why won’t they assign a CVE? @Broadcom

@IntCyberDigest Faraday cage your router. Wired connection only. Why aren’t people schizo enough

@IntCyberDigest It literally seems like every piece of hardware or software ever eventually has a root exploit. Kinda insane

@IntCyberDigest @Dinosn Wow but maybe the exploit can be used to patch devices?

@IntCyberDigest This is why I remove all broadcom wifi chips from devices. Here's me doing it to a cable modem because I don't trust their architecture/firmware blobs.

@IntCyberDigest I found this bug long ago. Broadcom won't patch it.

@IntCyberDigest The bug is 10+ years old and they won’t acknowledge or fix it
Why are these chips still in so many routers lol

@IntCyberDigest How likely is it that this is not a bug, I wonder.

@IntCyberDigest If it’s been there since 2010 and they aren’t assigning a CVE does that mean it was supposed to be there?? 🤔

@IntCyberDigest does this also affect consumer/client devices with broadcom wifi cards? (like MacBooks or the Google Pixel series)

@IntCyberDigest so ur telling me anyone could walk around with a contraption that automatically hacks routers, and the routers can both hack nearby routers and also tell user to install a certificate and mirror every bit of traffic to a C2 server? @grok

@IntCyberDigest Great research by Quentin Kaiser. A Wi-Fi flaw dating back to 2010 that needs no password is a good reminder to keep router firmware on the patch list, at home and at the office.

@IntCyberDigest @thegrugq No imagine this company would be to China?
But now since it’s US spying technology it is ok and perfectly normal.

@IntCyberDigest Absolutely phenomenal!
Knowing first hand how that company operates.... They might not have enough people to deal with that vulnerability

@IntCyberDigest Simple version: lots of home Wi-Fi boxes have a broken lock from 2010. Someone parked outside can open it without your Wi-Fi password and take over the box. Broadcom never gave it an official bug number, which may be why so many never got fixed. #EkonLabs #Marvin

@IntCyberDigest EternalBlue, not for Windows but rather routers. So nostalgic!

@IntCyberDigest If you have a Broadcom router, you should probably flash it with openWRT firmware.
