Summary
Malicious Package in retcodelog
Details

All versions of retcodelog contain malicious code. The package uploads system information to a remote server, downloads a file and executes it.

Recommendation

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.

Malicious Package in alico
Details

All versions of alico contain malicious code. The package uploads system information to a remote server, downloads a file and executes it.

Recommendation

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.

Severity
9.8 (Critical)

Vulnerability from github – Published: 2026-05-18 17:55 – Updated: 2026-05-18 17:55

Summary
Broken dropper in @mistralai/mistralai, @mistralai/mistralai-azure, @mistralai/mistralai-gcp
Details

Mistral npm @mistralai/mistralai, @mistralai/mistralai-azure, @mistralai/mistralai-gcp were compromised by a supply chain attack related to the TanStack security incident. An automated worm associated with the attack led to compromised npm package versions being published.

Current investigation indicates that an affected developer device was involved. We have no indication that Mistral infrastructure was compromised. The compromised versions were removed from npm. They were available only between May 11 at 22\:45 UTC and May 12 at 01\:53 UTC. Previous and later versions are not affected by this advisory.

Impact

The dropper is broken, it has no impact. - setup.mjs references tanstack_runner.js but the payload file is named router_init.js - execFileSync throws ENOENT and the tmpdir is wiped before payload runs. Bun gets downloaded to a tmpdir but no payload execution.

We still recommend removing the packages, see below for remediation.

Check whether you are affected

You are affected if one of the package versions above was installed in any environment during the exposure window or is present in a lockfile, build artifact, container image, package cache, or deployment image.

Package Affected versions
@mistralai/mistralai 2.2.2, 2.2.3, 2.2.4
@mistralai/mistralai-azure 1.7.1, 1.7.2, 1.7.3
@mistralai/mistralai-gcp 1.7.1, 1.7.2, 1.7.3

Check installed versions:

npm ls @mistralai/mistralai @mistralai/mistralai-azure @mistralai/mistralai-gcp
grep -n -A 4 -B 2 -E '@mistralai/(mistralai|mistralai-azure|mistralai-gcp)|2\.2\.[2-4]|1\.7\.[1-3]' \
  package-lock.json pnpm-lock.yaml yarn.lock 2>/dev/null

Look for any of the following files - router_init.js (embedded in all @tanstack packages): ab4fcadaec49c03278063dd269ea5eef82d24f2124a8e15d7b90f2fa8601266c - tanstack_runner.js (from git commit): 2ec78d556d696e208927cc503d48e4b5eb56b31abc2870c2ed2e98d6be27fc96 - @tanstack/setup package.json: 7c12d8614c624c70d6dd6fc2ee289332474abaa38f70ebe2cdef064923ca3a9b

You may also run this (read-only) script that will automatically flag known malicious files.

You are not affected by this advisory if you did not install the affected package versions and they are not present in your lockfiles, build caches, deployment artifacts, or package mirrors.

If the command finds an affected version, continue with the remediation steps below. If you use private package mirrors, caches, or container base images, check those copies too.

Remediate affected systems

  1. Stop using the affected package version immediately.
  2. Clean systems where one of this package has been installed.

Mitigation
Implementation Operation

Remove the malicious code and start an effort to ensure that no more malicious code exists. This may require a detailed review of all code, as it is possible to hide a serious attack in only one or two lines of code. These lines may be located almost anywhere in an application and may have been intentionally obfuscated by the attacker.

CAPEC-442: Infected Software

An adversary adds malicious logic, often in the form of a computer virus, to otherwise benign software. This logic is often hidden from the user of the software and works behind the scenes to achieve negative impacts. Many times, the malicious logic is inserted into empty space between legitimate code, and is then called when the software is executed. This pattern of attack focuses on software already fielded and used in operation as opposed to software that is still under development and part of the supply chain.

CAPEC-448: Embed Virus into DLL

An adversary tampers with a DLL and embeds a computer virus into gaps between legitimate machine instructions. These gaps may be the result of compiler optimizations that pad memory blocks for performance gains. The embedded virus then attempts to infect any machine which interfaces with the product, and possibly steal private data or eavesdrop.

CAPEC-636: Hiding Malicious Data or Code within Files

Files on various operating systems can have a complex format which allows for the storage of other data, in addition to its contents. Often this is metadata about the file, such as a cached thumbnail for an image file. Unless utilities are invoked in a particular way, this data is not visible during the normal use of the file. It is possible for an attacker to store malicious data or code using these facilities, which would be difficult to discover.
