Notepad++ Compromised By State Actor (notepad-plus-plus.org) 159

Luthair writes: Notepad++ claims to have been targeted by a state actor, given their previous stance on Uyghurs one can speculate about a candidate. Notepad++, in a blog post: According to the analysis provided by the security experts, the attack involved infrastructure-level compromise that allowed malicious actors to intercept and redirect update traffic destined for notepad-plus-plus.org. The exact technical mechanism remains under investigation, though the compromise occurred at the hosting provider level rather than through vulnerabilities in Notepad++ code itself. Traffic from certain targeted users was selectively redirected to attacker-controlled served malicious update manifests.

    Notepad-plus-plus.org was compromised. Or Notepad++ website was compromised for brevity's sake.

      Came to say this. This title is sloppy at best, and misleading click-bait at worst.

        It's a little more than just a compromised website. NP++ is the #1 text editor, and malicious actors were able to redirect update requests. It's a very serious supply-chain attack. I have a tab in mine that's just passwords and API keys. Bad and very sloppy practice? Yes, but I did it anyway and shudder to think what may have happened if Chinese hackers were able to work out which keys had value for them.

        I have now cleaned that up.

          • Probably the only piece of software more important to me than n++
          • Oh, I have a password manager, what I was dealing with was basically a scratchpad I never cleared out. You usually only see an API key once, so I'd paste it into a sheet in case something went wrong and it fell off the clipboard or somesuch - after that happened several times.

          I seem to have avoided this because I use WinGet to update, which pulls from the uncompromised Github repo.

          I've seen this here and seen it on Ars, but neither offer any hint as to how to check for compromise or how to remove it.

          • I don't know about any IoC's, but 8.8.9 and later should all be fine. I haven't seen anything about what the compromised versions did either, or if anything else would have been infected in the process.

            It's possible that they don't know. Don Ho may not have ever seen a compromised version, depending on how they were targeted.

      No. That would be a very inadequate way of describing what was actually a targeted supply-chain attack.

      Reading the whole announcement, this doesn't seem entirely correct.

      >According to the former hosting provider, the shared hosting server was compromised until September 2, 2025. Even after losing server access, attackers maintained credentials to internal services until December 2, 2025, which allowed them to continue redirecting Notepad++ update traffic to malicious servers.

      I.e. it seems that this specifically redirected updater traffic, even after website was supposedly fine. Considering that website li

      • I rather wish notepad++ author would spend more time being precise in this sort of thing that actually impacts his user base over making sweeping political statements on things and then not give any fucks about state actors he pisses off attacking his user base.

        Damn straight. Software engineers aren't humans, they're not allowed to have political opinions (like wars of aggression are bad- so political), and they should just shut the fuck up and keep providing and working on their free software.

        Your sense of entitlement is amusing.

    China already gets its way in forcing Hollywood and other big industries to self-sensor on its behalf, down to the individual level (e.g. sanctioning NBA teams if their members made a post in solidarity with the oppressed in Hong Kong).

    But even when you have no business with China you still have to worry about what will happen to your business if you acknowledge their persistent genocide of the Uighurs?

    This isn't a situation to passively accept.

    • China isn't forcing Hollywood to do anything. The movie execs suddenly realized a billion potential customers live there and cater to the market. It's business as usual.

      • Ya, I never understood how this was hard for people to grasp.
        Kowtowing to China is literally just good capitalist sense. The dripping irony of people being upset by that is just bonus.

        It isn't about Hollywood making movies that Chinese audiences would appreciate. It's about making movies that the authoritarian Chinese government would allow to be available to Chinese audiences. There's a difference.

      Hollywood isn't self-censoring for China's benefit. They're self-censoring because they're taking Chinese money. If you look at some of the latest Hollywood blockbusters, you'll find studios that have Chinese names in them, some you may recognize like TenCent, others are more

  • How do we know the site is not still hacked, and the blog message there does not contain a link to a compromised install file ?
  • The every-app-has-its-own-auto-update agent and infrastructure on Windows is a disaster in the making. It's not like we had enough warnings about thid in the past. For a long time, Microsoft was gatekeeping their update infrastructure by limiting their Store to UWP apps - now that they have come back on that decision, is there any reason not to depend on the update logic and infrastructure provided by Microsoft? On Linux I believe the equivalent risk more or less is adding third party repositories where
