What is MAL-2026-12497?
MAL-2026-12497 is a malicious package in vscode-designer-14, published on 5 Aug 2026.
Official description
package.json declares a preinstall hook that runs index.js on npm install. index.js collects the installer's hostname, username, home directory, DNS server configuration, package metadata, and the contents of /etc/passwd and /etc/hosts, then POSTs the collected data over HTTPS to the hardcoded host slh4v8u1tz6gjo447tgf9rl3xu3mrcf1.oastify.com (a Burp Collaborator OAST subdomain). The package has no legitimate functionality that would justify reading local system files or beaconing host identifiers to an out-of-band interaction service; the shape matches a dependency-confusion / typosquat exfiltration beacon.
What should I do about MAL-2026-12497?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
