GHSA-74HH-4RCV-PP27
Vulnerability from github – Published: 2020-09-04 16:44 – Updated: 2021-10-01 20:43All 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.

Vulnerability from github – Published: 2023-05-24 16:43 – Updated: 2023-05-24 16:43Impact
bignum releases from v0.12.2 to v0.13.0 (inclusive) used node-pre-gyp to optionally download pre-built binary versions of the addon. These binaries were published on a now-expired S3 bucket which has since been claimed by a malicious third party which is now serving binaries containing malware that exfiltrates data from the user's computer.
Patches
v0.13.1 does not use node-pre-gyp and does not have support for downloading pre-built binaries in any form, avoiding the risk of malicious downloads.

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.
