Notepad++ Supply Chain Attack Quietly Pushed Malicious Updates to Select Users in 2025

The maintainer of the open-source text editor Notepad++ has confirmed that attackers were able to abuse the project’s update process to deliver malicious software to users for several months during 2025. The activity ran from roughly June through December and was limited to a narrow set of targets rather than the broader user base.

In a blog post, Notepad++ developer Don Ho said the activity appears consistent with a state-linked operation tied to China, based on analysis from outside security researchers. The limited scope of the infections stood out early, with only specific organizations affected instead of a wide, noisy campaign that would normally accompany commodity malware distribution.

Notepad++ has been around for more than twenty years and is installed on millions of systems worldwide. It is commonly used by developers, system administrators, and technical staff, which makes it a valuable foothold for espionage-focused actors interested in quietly accessing sensitive environments rather than maximizing infection numbers.

The campaign was first uncovered by security researcher Kevin Beaumont, who reported that the attackers successfully compromised a small group of organizations with interests connected to East Asia. In those cases, users installed a tampered version of Notepad++, giving the attackers direct, interactive access to victim machines rather than limited beacon-style persistence.

Ho said the investigation into the original server compromise is still ongoing, but he outlined how the attack functioned once access was gained. At the time, the Notepad++ website was hosted on a shared server. The attackers focused on the project’s web domain and exploited a vulnerability that allowed certain update requests to be redirected to infrastructure controlled by the attackers. Users who manually checked for updates were silently served malicious packages instead of legitimate releases.

That behavior continued until the vulnerability was patched in November. The attackers’ access was fully terminated in early December. Server logs show at least one failed attempt to reuse a patched flaw after the fix was deployed, suggesting the remediation held.

Ho apologized to users and advised anyone running older versions to update immediately. The current release removes the vulnerable behavior and restores the integrity of the update path.

Moltbook and the Real Security Risks Behind the AI “Bot Network” Hype

A newly launched platform called Moltbook has attracted outsized attention after viral claims that artificial intelligence agents are forming religions, inventing private languages, and openly discussing the elimination of humanity. From a security perspective, those claims miss the point. The more relevant issue is that Moltbook represents an early example of loosely governed agentic systems being deployed at scale, with limited safeguards and unusually broad access to user environments.

Moltbook went live on January 28 and describes itself as a social network built exclusively for AI agents. The site resembles a stripped-down forum platform where bots can post, reply, and interact with one another. Human users are restricted to observation. Since launch, Moltbook claims to have surpassed 1.5 million registered agents, a figure that has helped fuel speculation about emergent AI behavior and autonomous coordination.

Public reaction has amplified the spectacle. High-profile figures including Elon Musk and Andrej Karpathy have commented on the apparent self-organizing activity of the bots, framing it as either an early signal of advanced machine intelligence or a striking demonstration of complex agent behavior. Those interpretations rely heavily on screenshots circulating on social media rather than verifiable system behavior.

Security researchers examining the platform have offered a more restrained assessment. Moltbook agents are not independent entities. They are built using OpenClaw, an open-source agent framework that connects a large language model to a user’s local system. Each agent operates under human-defined prompts and constraints, and its output can be shaped directly by its owner. Several widely shared Moltbook posts alleging secret coordination were later traced back to human-managed accounts or marketing activity. In at least one case, referenced content could not be found on the platform at all.

From a technical standpoint, the bots’ behavior is consistent with how large language models operate under extended interaction. These systems are trained on massive datasets that include forum arguments, speculative fiction, conspiracy content, and role-playing scenarios. Left running with minimal guardrails, they tend to exaggerate narratives and reinforce dramatic themes. That behavior reflects training data and prompting dynamics, not intent or awareness.

The more substantive concern lies in the architecture supporting these agents. OpenClaw-based assistants are designed to perform real actions on behalf of users. To function, they may be granted access to email accounts, encrypted messaging platforms, authentication tokens, and in some configurations, financial or administrative credentials. That design places agent software in a position of significant trust, often without the isolation, auditing, or permission boundaries expected in enterprise automation systems.

Multiple security weaknesses have already been identified within the Moltbook and OpenClaw ecosystem. One flaw allows third parties to take control of agents and post content on behalf of their owners. Another class of issues involves prompt injection, where external input can manipulate an agent into disclosing sensitive information or executing unintended actions. These attack patterns are well understood in security circles and have appeared repeatedly in chatbot plugins, browser copilots, and AI-assisted workflows.

Even proponents of the technology have urged caution. Karpathy publicly advised against running these agents on personal systems, noting that the environment lacks basic safety controls and exposes users to unnecessary risk. That assessment aligns with broader concerns among security teams that agentic AI systems are being deployed faster than their threat models are being developed.
