Dindonmasker comments on Notepad++ Hijacked by State-Sponsored Hackers

You might have version 8.8.1 or lower, however it might have tried to order update got the vulnerable package instead and then remained on the older version. I think even if you have the older version that's not a sign that you weren't compromised.

Fair point. I was assuming the malicious payload would come along with an update on order to hide, but it's also possible that the malicious payload was delivered without any update to notepad++.

I've not seen any IOCs published have you?

There's some IOC information here:

I'm not sure what you mean. The article states there were remote hands on keyboard noticed in multiple companies. That's how the vulnerability was discovered.

I mean IOCs that you can scan for in an environment to see if a machine has been compromised using this vulnerability. Something that tells you if you need to do additional remediation on a machine or just update notepad++ and move on.

Edit: Found some! This is the type of info I was thinking of when I used IOCs

How would you know if you updated?

My notepad++ is on 8.9.1 and I have no idea how it's on that ver (ninite I think is where I sourced it....maybe it's auto updating?)

the safe thing to do is uninstall, then download from the new (theoretically more secure) website and install the new (theoretically more secure) 8.9.1.

That won't rescue your system if it is already compromised though. It will just prevent it from being newly compromised in this manner.

Unfortunately i do work for a targeted company (we do a lot of secret squirrel stuff) in south East Asia.

We get a lot of attacks.

I was looking at the attack and malware they inject (there is a blog post link on the notepad++ notice) which pointed out how the attack worked. Apparently they run a service called bluetoothservice.exe. I didn't see anything like that or any the other stuff they said gets created.

But then again finding malware isn't my bag so who knows.

Pretty sure my updates came via nanite installer so I'm hoping I wasn't targeted.
