Putting A Patch On The Problem
Log4j was released for mass usage 20 years ago in 2001, leaving many wondering how long has the flaw in the code been wild and why it took so long to have been discovered and taken advantage of.
That’S Not Data—That’S Code!
Java and Open-Source
- Log4j is written in Java, which means it doesn’t intrinsically have protections like DEP and ASLR. On the other hand, it’s an open-source package. That means anybody (well, anybody with coding skills) can read the source code, spot any bugs, and contribute to improving the package. The theory is that open-source code is safer because it’s been examined by many sets of eyes, and b…
Why Is It Everywhere?
- When there’s a security hole in an operating system or a popular browser, it typically affects just the users of that operating system or that browser. The publisher works up a new version that patches the hole, pushes out an update, and all’s well. Log4j is different. It’s not an operating system, or a browser, or even a program. Rather, it’s what coders call a library, or a package, or …

Apple, Cloudflare, Twitter, Valve, and other large companies ...
What Can I do?
- The Log4j exploit is just one of many security holes being exploited by bad actors. The CISA’s exploited vulnerabilities catalog(Opens in a new window)lists 20 found in December alone. Looking closely, you’ll see that some are fixed already, but others have a fix that’s not due for six months or more. Few will have the impact of the Log4j exploit, of course.
