Malicious code in clickfix_npm_delivery (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (f795362044848bcb73d95317e8761c4315720d6a052c6c88fdab47065499510d) The package has no library surface. `package.json` declares `main: index.html` and the tarball ships only that HTML page, whose sole purpose is a ClickFix social-engineering lure. The page impersonates Cloudflare Turnstile (Cloudflare branding, a spoofed `dash.cloudflare.com` header, a fake 'Verify you are human' checkbox, and a fake 'Ray ID / 403 Forbidden' bot-detection screen). When the victim clicks the fake checkbox, the page silently writes a PowerShell one-liner to the clipboard and instructs the victim to press Win+R, paste, and hit Enter. The clipboard payload uses `Start-BitsTransfer` to download a script from `http://ec2-65-2-4-62.ap-south-1.compute.amazonaws.com:443/script` over plain HTTP into `$env:temp\sys.ps1` and executes it via `iex (gc $t -Raw)`, giving the operator of that EC2 host arbitrary code execution on the victim's Windows machine. The package name (`clickfix_npm_delivery`) and description ('Delivery POC Package') identify npm itself as the distribution channel for the lure. ## Source: ghsa-malware (a92eb0e7964a67df5bb46bd87559b74f949ee053811eb36679aad4d42342f8f3) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
