GHSA-9X64-5R7X-2Q53
Vulnerability from github – Published: 2020-09-01 21:21 – Updated: 2021-10-01 13:30Version 0.1.1 of flatmap-stream is considered malicious.
This module runs an encrypted payload targeting a very specific application, copay and because they shared the same description it would have likely worked for copay-dash.
The injected code:
- Read in AES encrypted data from a file disguised as a test fixture
- Grabbed the npm package description of the module that imported it, using an automatically set environment variable
- Used the package description as a key to decrypt a chunk of data pulled in from the disguised file
The decrypted data was part of a module, which was then compiled in memory and executed.
This module performed the following actions:
- Decrypted another chunk of data from the disguised file
- Concatenated a small, commented prefix from the first decrypted chunk to the end of the second decrypted chunk
- Performed minor decoding tasks to transform the concatenated block of code from invalid JS to valid JS (we believe this was done to evade detection by dynamic analysis tools)
- Wrote this processed block of JS out to a file stored in a dependency that would be packaged by the build scripts:
The chunk of code that was written out was the actual malicious code, intended to be run on devices owned by the end users of Copay.
This code would do the following:
- Detect the current environment: Mobile/Cordova/Electron
- Check the Bitcoin and Bitcoin Cash balances on the victim's copay account
- If the current balance was greater than 100 Bitcoin, or 1000 Bitcoin Cash:
- Harvest the victim's account data in full
- Harvest the victim's copay private keys
- Send the victim's account data/private keys off to a collection
Recommendation
If you find this module in your environment it's best to remove it. The malicious version of event-stream and flatmap-stream have been removed from the npm Registry.

Vulnerability from github – Published: 2018-11-09 17:42 – Updated: 2023-09-14 17:55The nodemssql package is a piece of malware that steals environment variables and sends them to attacker controlled locations.
All versions have been unpublished from the npm registry.
Recommendation
As this package is malware, if you find it installed in your environment, the real security concern is determining how it got there.
If you have found this 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 registry credentials, tokens, and any other sensitive credentials that may have been present in your environment variables.
Additionally, any service which may have been exposed via credentials in your environment variables, such as a database, should be reviewed for indicators of compromise as well.

Vulnerability from github – Published: 2020-09-02 21:43 – Updated: 2021-09-30 21:56Version 3.4.6 of uglyfi-js contains malicious code as a preinstall script. The package is malware designed to take advantage of users making a mistake when typing the name of a module to install. When installed, the package downloads a file from a remote server, executes it and opens a backdoor.
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.

Mitigation
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.
