As Wired explains, the Log4j vulnerability is very, very easy to exploit. All a hacker needs to do is send a single string of malicious code, which then gets logged by Log4j.

The flaw and a proof-of-concept exploit was publicly released on Friday, wreaking havoc across companies that use the popular Log4j Java platform. Impacted firms included Amazon, Apple, Steam ...

Log4j vulnerabilities leave organisations open to various cyberattacks from cyber criminals who can easily scan for vulnerable instances to exploit. Not long after Log4j was disclosed, attempts ...

As previously said, if the original Java class exploit is unable to launch the Windows commands, it will assume the operating is a Unix/Linux device and download an 'm.py' python script instead.

The Log4j hack, also known as Log4Shell, already has a patch that companies can deploy. But it turns out that the fix has its own security issues that hackers can exploit.

Log4j update: Experts say log4shell exploits will persist for 'months if not years' Log4j flaw: Attackers are making thousands of attempts to exploit this severe vulnerability ...

Attackers are actively exploiting a critical vulnerability in Apache Log4j, a logging library that’s used in potentially millions of Java-based applications, including web-based ones ...

Microsoft also stated that Azure App Service and Functions does not distribute Log4J in the managed runtimes such as Tomcat, Java SE, JBoss EAP, or the Functions Runtime.

Even for C-based servers that are theoretically safe, a connected online form written in Java could lead to a compromise. Log4j is a critical threat, and no organization should assume it is safe.
