Many packages suddenly disappeared
PSA: Please be cautious because this is an excellent opportunity for taking over packages and injecting malware by malicious people.<p>Example: <a href="https://www.npmjs.com/package/duplexer3" rel="nofollow">https://www.npmjs.com/package/duplexer3</a> which has 4M monthly downloads just reappeared, published by a fresh npm user. They published another two versions since then, so it's possible they've initially republished unchanged package, but now are messing with the code.<p>Previously the package belonged to someone else: <a href="https://webcache.googleusercontent.com/search?q=cache:oDbrgPbT5m0J:https://www.npmjs.com/package/duplexer3" rel="nofollow">https://webcache.googleusercontent.com/search?q=cache:oDbrgP...</a><p>I'm not saying it's a malicious attempt, but it might be and it very much looks like. Be cautious as you might don't notice if some packages your code is dependent on were republished with a malicious code. It might take some time for NPM to sort this out and restore original packages.
