Opening Password Manager triggers MalwareBytes Warning / Compromised Website


Description of the issue:
Everytime Password Manager is opened, MalwareBytes triggers a pop-up window always about IP 20.212.64.14 Outbound Port 443 being blocked because it is compromised. Sometimes it identifies only the IP & Port; sometimes it also shows this domain as well: waws-prod-sg1-097-4aa1.southeastasia.cloudapp.azure.com

I don’t know how to resolve this.

How can this issue be reproduced?

  1. Simply opening Password Manager triggers the MalwareBytes pop-up every time.

Expected result:
No MalwareBytes error when opening Password Manager.

Brave Version( check About Brave):
Version 1.73.89 (Nov 13, 2024)

Additional Information:
I did an uninstall, cleaned the registry of Brave references. Did a clean install. No error message pops up from MalwareBytes when opening the Password Manager. However, as soon as I import my passwords, the MalwareBytes error pops up.

@Beavee,
Interesting. I have MWB on my macOS machine and have never seen this particular pop up. I wonder if it’s a Windows specific issue.

Will reach out to the team about this. Just to be clear this is almost certainly a false alarm.

Is it a static or dynamic IP? Try to restart the router and computer and see if this pop up shows up again.

Dynamic IP. Opened router log, then opened Brave Password Manager. MalwareBytes error pop-up appeared, but no suspicious activity in router log file.

Rebooted modem & router just now. Opened Password Manager, MalwareBytes pop-up again appeared.

Here is the alternate version of the MalwareBytes pop-up:

My own humble opinion:

Somehow, something (possibly a script downloaded), might (as in maybe) be affecting the Brave Password Manager - such that, the Brave Browser Password Manager acts/attempts to connect to a Microsoft cloud server (“Azure region” server) that is in Southeast Asia. Server IP address: 20.212.64.14

My guess is, that probably should not happen.

I do not use Malwarebytes, but my suggestion is, to click on the “Manage Exclusions” button, and where you can, then ENABLE/MAINTAIN blocking of the item.

Until you learn more. And, maybe start your Windows OS machine, into Safe Mode(?) and run a complete scan.


Using the Windows OS command line (command prompt), the following command

dir /p /o:d

Provides a list of files in chronological order, for your present directory. Very handy for finding recent virus invaders and their associates, that generally appear within a certain time frame (recent).

It is a lot of work, marching through Windows OS machine directories, in particular, the BraveSoftware directory and its sub-folders:

C:\Users[UserName]\AppData\Local\BraveSoftware\

but that is a handy command for finding some things . . . that ought not be on a PC.

Another tool - Kaspersky Rescue Disk:

  1. Save the Kaspersky Rescue Disk software to a USB memory device or a CD/DVD (to learn how to do this, see support.kaspersky.com/8092).
  2. Boot up your PC – from the storage device that contains Kaspersky Rescue Disk.
  3. Update the antivirus databases.
  4. Run a system scan on your PC and then follow the instructions on your screen.

After multiple attempts at logic to solve this, I circled back to “maybe it’s just something in the saved passwords that’s causing the issue.” It turns out, it was.

I deleted all passwords, and slowly uploaded 50 at a time, instead of the whole .csv file. I eventually isolated it to one password.

The problematic record, attached, was for a specific subdomain on .PlanetFitness.com. I don’t have a membership there anymore, so I deleted the record. (I also observe on the PF website, the member info is no longer available on that subdomain, but instead thru www.planetfitness.com/my-account/profile. )

I’m guessing that subdomain is either flagged at MalwareBytes, or it’s compromised but identified by simply loading the Password Manager which possibly does a quick online check of all domains referenced in the Password Manager upon each opening? I don’t know, but it’s fixed now. And apparently nothing glitch-y about Brave at all.

Thank you for your helpful suggestions.

I just did a search on Wayback Machine. The subdomain IS breached. Instead of a member sign-on page for Planet Fitness, this was captured on that subdomain in 2023:

Very good effort to be the detective and pursue the matter. Thank you; and, for detailing the Solution.

We have reached out to MWB and they have confirmed that they’ve removed the IP from the blocklist — fix should be live now (if not now then very shortly).
