Working for a bank did make me think much more about all the vulnerabilities that can go into certain tools. The company has a lot of bureaucracy to prevent installing anything or adding external dependencies.

Working for a fintech and being responsible for the software made me very wary of dependencies and weeding out the deprecated and EOL'd stuff that had somehow already found its way into what was a young project when I joined. Left unrestrained, developers will add anything if it resolves their immediate needs like you could probably spread malware very well just by writing a fake-blog advocating a malicious module to solve certain scenarios.
