The npm package 'ts-bigtn' versions 1.3.1 and 1.3.2 contain malicious code that can fully compromise any computer on which it is installed. This compromise may allow an attacker to gain full control over the affected system. Immediate removal of the package is advised, but due to potential persistent malicious software, simply removing the package may not fully remediate the infection. All secrets and keys stored on the compromised machine should be rotated from a separate, secure device.
