Malware Detected on Umbrel

Hi there - I’m running the latest version of Umbrel on a Raspberry PI 4 with an 16GB MCSD and 1 TB SSD. I recently updated the wifi network in my home to use Netgear Orbi wifi 6 mesh network to get better coverage in my home. I have the umbrel hooked up to an ethernet port on the main router.

When I setup the network it came with security software called Netgear Armor - and it scans the network devices for potential security threats and can block them. So far nothing on my network has been problematic except that I’ve got 12 unique notifications of malware and phishing originating from my umbrel node (raspberry pi) but this software says it is blocking it.

Phishing

Attack
Detected a suspicious remote location 91.123.158.251 attempted a connection to umbrel and blocked that connection.

So I’m not sure I’ve something in my root image on the raspberry pi has been compromised or if this is related to legitimate traffic that the umbrel is doing on TOR that Netgear may not like and how do I resolve it. Maybe I just flash the whole thing, format the SD and update firmware for the raspberry pi?

Thanks!

I have just installed this week the latest version of umbrel os, and after security tests i see the device reaching out to known listed malware/log4j targets, i will investigate this further:

1 - stopping all apps (I had around 4 running)
2 - starting and checking apps individually

My questions:
1 - Does Umbrel or anyone checks the base os for security concearns?
2 - Does Umbrel or anyone checks the apps on matketplace?

Thanks in avance, any contribution is valid

Oh, if that’s true, it sounds serious… Could you provide more info about the issue what you have found, please? What addresses it’s reaching out? Or maybe you’ve found more about it already? Any suspicious apps/processes? Thank you.

More info, and i will update further

Thank you for the info. As for now I can confirm a sporadic traffic from my Umbrel targeting port 7777 somewhere, but it looks like a normal I2P traffic which my Bitcoin node is using. Nothing else on the mentioned ports detected so far. Umbrel 1.4.2. Will update if I spot anything new.

Did you check the related ips?

a few from the range of 23.128.248.0/24 and a single one 141.94.45.159. apparently it’s originating from the bitcoin node app.

I advise a check of the ips against know log4j malware lists,

and maybe you can help with the more important questions:
1 - Does Umbrel or anyone checks the base os for security concerns?
2 - Does Umbrel or anyone checks the apps on marketplace?

Unfortunately I can’t help with the questions you brought up here. I’m just a common user. The project is opensource so in theory anyone can do the necessary checks. I believe the developers do, but yeah, maybe it’s just my false beliefs.. :man_shrugging:
