I'm genuinely curious if other developers take the time to vet NPM packages before adding them to their projects. Recently, we almost merged a pull request that included a package with a typo—"reqeusts" instead of the legitimate "requests". The fake package had a postinstall script that attempted to extract environment variables, which is pretty terrifying. When I consulted our security team, they suggested using npm audit, but that only identifies known vulnerabilities and doesn't guard against zero-day or typosquatting issues. To counter this, I've developed a script that scans packages for suspicious patterns prior to CI merges. This catches things like unsafe lifecycle hooks, attempts to read environment variables, and obfuscated code. Although it caught the fake package, it flagged two legitimate ones (torch and tensorflow) due to their binary downloads, but those can be whitelisted. My manager thinks I'm wasting my effort and just wants to rely on Snyk, which costs $1200 a month and still doesn't address typosquatting. Am I being overly cautious, or is there a larger issue that programmers should address?

You're definitely not crazy. Most teams don’t manually check every dependency, but they do implement guardrails. Private registries, allowing specific dependencies, and running static checks in CI help manage risks effectively. Your script sounds like a solid solution and adds a layer of security in the supply chain.
Honestly, many developers skip the in-depth review due to time pressure. But relying solely on tools like npm audit isn't enough. Implementing lightweight checks, like requiring justification for new dependencies, can help create a cautious culture without overwhelming the team.
It's smart to be cautious! In our setup, we have a policy against pulling packages directly from the internet. We use an internal repository manager like Artifactory to handle dependencies, along with an x-ray tool to check for vulnerabilities. This way, we have a buffer to catch issues before they reach production.
I've been in teams where we face the same dilemmas. We maintain a whitelist of approved packages and use tools that check for suspicious activity during build processes, which can catch typosquatting. Communication with leadership about perceived risks versus actual risks is key—document everything to justify your precautionary measures.
Your manager may not understand the potential fallout from negligence here. Incorporating a clear package approval process is crucial. Getting everything down in writing about your recommendations and their risks can help protect you and the team from future security incidents.
