The ldpbootstrap-jquery package includes an 8KB encrypted PowerShell script that is decrypted using a hardcoded XOR key and executed on Windows endpoints with execution policy bypass and hidden windows to evade antivirus detection. Additionally, it fetches session-specific PowerShell scripts over plain HTTP from a configurable API endpoint, which are also executed stealthily. The package's README documents antivirus evasion techniques and the use of per-session XOR keys for delivery. The malicious payload execution is triggered through the package API, not automatically on install or require, but following documented usage. This design enables attackers to distribute malware and gain full control over affected computers.

Any system running this package and executing its documented API calls is fully compromised, allowing attackers to run arbitrary PowerShell code with stealth techniques that bypass execution policies and antivirus detection. This can lead to complete system takeover, exposure of stored secrets and keys, and persistent malware presence. Removal of the package alone does not guarantee eradication of all malicious components due to the level of control attackers gain.

No official patch or fix is available for this malicious package. The recommended mitigation is immediate removal of the ldpbootstrap-jquery package from all systems. All secrets and keys stored on compromised machines should be rotated from a separate, trusted device. Due to the full compromise risk, affected systems should be considered untrusted and thoroughly investigated for persistent malware beyond the package itself.
