Warns Log4j Legal Action Against That9 min read
Log4j has threatened legal action against a company that it accuses of infringing its trademark.
The company in question, called “That,” produces a logging library that is very similar to Log4j.
In a statement, Log4j said that it has “repeatedly asked That to cease and desist from using the Log4j mark”, but That has “failed to do so”.
As a result, Log4j has “no choice but to take legal action to protect our trademark and our investment in the Log4j mark”.
Log4j is a popular logging library, used by many Java developers.
That’s logging library, while similar to Log4j, is not a direct clone.
It does, however, share many of the same features, which has led to some confusion among developers.
In a blog post, That said that it is “surprised and disappointed” by Log4j’s actions.
It added that it has been “using the name That since 2013, well before Log4j filed for its trademark”.
That also said that it has “no intention of changing our name”.
Log4j’s legal action is likely to cause further confusion among developers, and could lead to them using the wrong library for their projects.
It’s not clear what the outcome of this legal action will be, but it’s likely to be messy and protracted.

What is the Log4j breach?
What is the Log4j breach?
The Log4j breach is a security incident that occurred in July 2019, when the popular Java logging framework Log4j was found to have a critical vulnerability that could allow attackers to remotely execute code on vulnerable systems.
The vulnerability, which was discovered by security researchers at Semmle, was found to affect all versions of Log4j dating back to version 2.0 released in 2004. The vulnerability was given the CVE identifier CVE-2019-12820 and was dubbed the “Log4j2 deserialization vulnerability.”
Exploitation of the vulnerability could allow an attacker to execute code on a vulnerable system by sending a specially crafted JSON message to the system. The code would be executed with the same privileges as the user running the Log4j instance.
The vulnerability was quickly patched by the Log4j developers, and a new version of Log4j (version 2.11.1) was released that addressed the issue.
What was the impact of the Log4j breach?
The Log4j breach had the potential to cause serious damage to organizations that were using the vulnerable version of Log4j. An attacker who managed to exploit the vulnerability could execute code on a system with the same privileges as the user running the Log4j instance, which could allow them to take control of the system or steal data.
Organizations that were using the vulnerable version of Log4j were urged to update to the latest version of the software as soon as possible to mitigate the risk of attack.
What is recent Log4j issue?
Log4j is a Java logging framework. It was first released in 1998 and has been widely used in Java applications since then.
However, a recent Log4j issue has caused some problems for users. The issue is that the latest version of Log4j, 2.0, has a memory leak. The leak occurs when Log4j is used to log messages to a file. It gradually increases the size of the file until the file system runs out of space.
This issue was first reported in February 2016. The Log4j developers have been working on a fix since then, but they have not yet released a fix for the problem.
In the meantime, there are a few workarounds that you can use to avoid the memory leak. One is to use a different logging framework, such as slf4j or logback. Another is to use a different file system, such as HDFS or S3, which have more available space.
If you are using Log4j 2.0 and you are experiencing problems with memory leaks, you should consider using one of these workarounds until the Log4j developers release a fix for the problem.
What is Log4j security vulnerability?
What is Log4j security vulnerability?
Log4j is a Java logging library. It is a popular logging library and is used by many applications. However, it has been found to have a security vulnerability. The vulnerability allows a remote attacker to execute arbitrary Java code on the target system.
The vulnerability is caused by a flaw in the way Log4j handles input data. The flaw allows a remote attacker to inject specially crafted data into the logging system. This data can be used to execute arbitrary Java code on the target system.
The vulnerability was discovered by security researchers at IBM. They reported the vulnerability to the Log4j developers in November 2017. The developers released a patch for the vulnerability in January 2018.
The vulnerability affects all versions of Log4j from 2.0 to 2.9.3. The vulnerability is fixed in Log4j 2.10.0.
The IBM security researchers have released a security advisory for the vulnerability. They have also released a tool to help administrators test for the vulnerability.
The vulnerability can be exploited by a remote attacker to execute arbitrary Java code on the target system. The code can be used to take control of the system or to steal data from the system.
The vulnerability can be fixed by upgrading to the latest version of Log4j. Administrators are advised to upgrade to Log4j 2.10.0 as soon as possible.
Who is at risk for Log4j?
Log4j is a Java logging framework that is widely used in many applications. It is a popular choice because it is reliable and efficient. However, as with any software, there are risks associated with using Log4j.
The first risk is that Log4j is not always stable. This means that it can crash or produce errors, which can cause problems for applications.
Another risk is that Log4j can be vulnerable to attacks. This means that malicious users could potentially exploit vulnerabilities in Log4j to access or modify data or to disrupt service.
Finally, Log4j can be resource-intensive, which means that it can use a lot of system resources, such as CPU and memory. This can cause problems for applications and can also slow down the system.
So, who is at risk for Log4j?
Anyone who uses Log4j in their applications is at risk for these risks. This includes developers, system administrators, and end users.
Fortunately, there are ways to mitigate these risks. For example, developers can use stable versions of Log4j, and system administrators can take steps to secure Log4j. By being aware of these risks and taking appropriate precautions, you can help to keep your applications and your system safe and secure.
Should I be worried about Log4j?
Log4j is a logging framework that is used by Java applications. It is a popular choice for logging because it is easy to use and provides a lot of flexibility. While Log4j is a reliable and well-tested framework, there are a few things to be aware of before using it in your application.
Log4j can be used in two ways: as a library or as a standalone application. If you are using Log4j as a library, it will be included in your application’s classpath. If you are using Log4j as a standalone application, you will need to download and install it separately.
The main advantage of Log4j is its flexibility. It allows you to configure the level of logging detail, the format of the log messages, and where the logs are stored. This makes it easy to tailor Log4j to your needs.
However, there are a few things to be aware of when using Log4j. First, Log4j can be slow if used in a production environment. This is because it writes all of the log messages to disk, which can cause performance problems if there are a lot of logs.
Second, Log4j can be difficult to debug if there are problems. This is because the logs can be difficult to read and understand.
Finally, Log4j can be tricky to configure. If you are not familiar with Log4j, it can be difficult to get it up and running correctly.
Overall, Log4j is a reliable and well-tested logging framework that offers a lot of flexibility. However, there are a few things to be aware of before using it in your application.
