Summary

Details

The cofeescript package is a piece of malware that steals sensitive data such as a user's private SSH key and bash history, sending them to attacker controlled locations.

All versions have been unpublished from the npm registry.

Recommendation

If you have found cofeescript installed in your environment, you should: 1. Delete the package 2. Clear your npm cache 3. Ensure it is not present in any other package.json files on your system 4. Regenerate your SSH keys, registry credentials, tokens, and any other sensitive credentials that may have been present in your bash history.

Additionally, any service which may have been exposed via credentials in your bash history or accessible via your ssh keys, such as a database, should be reviewed for indicators of compromise as well.

Summary
Malicious Package in signqle
Details

All versions of this package contained malware. The package was designed to find and exfiltrate cryptocurrency wallets.

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.

Summary
Malicious Package in eslint-config-airbnb-standard
Details

Version 2.0.0 of eslint-config-airbnb-standard was published with a bundled version of eslint-scope that was found to contain malicious code. This code would read the users .npmrc file and send it's contents to a remote server.

Malicious Package in bsae-x
Details

All versions of this package contained malware. The package was designed to find and exfiltrate cryptocurrency wallets.

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.

All versions of this package contained malware. The package was designed to find and exfiltrate cryptocurrency wallets.

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.

Summary
Malicious Package in experss
Details

All versions of experss typosquatted a popular package of similar name and tracked users who had installed the incorrect package. The package uploaded information to a remote server including: name of the downloaded package, name of the intended package, the Node version and whether the process was running as sudo. There is no further compromise.

Recommendation

Remove the package from your dependencies and always ensure package names are typed correctly upon installation.

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.
