Many packages suddenly disappeared
PSA: Please be cautious because this is an excellent opportunity for taking over packages and injecting malware by malicious people.Example: https://www.npmjs.com/package/duplexer3 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.Previously the package belonged to someone else: https://webcache.googleusercontent.com/search?q=cache:oDbrgP...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.
