Log4j 2.15.0 – Previously suggested mitigations may not be enough
Logstash is a hugely popular service for collecting/processing/shipping logs, mainly associated with elasticsearch ("ELK") but has lots of output plugins. It uses log4j, so if one of the log events it was processing contained an exploit string, and also caused logstash to encounter an error processing or shipping the message, that message would get logged to logstash's own log, thus triggering the exploit deep in someone's infrastructure.
probably not too hard to come up with a way to break one of the many "grok" pattern regexes https://github.com/logstash-plugins/logstash-patterns-core/b...

Hackers exploited Windows 0-day for 6 months after Microsoft knew of it
I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

The Dedicated Maintainers Behind Lesser-Known Open Source Projects
However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.

Apache POI Setup Logging Error
What you need is log4j-core, what you downloaded is some kind of connector between log4j and JUL. Tbh I don't know what JUL is, but that's not important. You can get log4j-core on from the official website - https://logging.apache.org/log4j/2.x/ or in maven repo. In case you're not using maven, I highly, highly recommend you using it for managing your dependencies.

Log4Shell Still Has Sting in the Tail
> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.
> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...
Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.
Remember: this vulnerability was disclosed to them in November.
