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.

Log4j is a programming code written in Java computer language. It was created by Apache Software Foundation volunteers to run on different platforms — including macOS, Windows and Linux.

There are 17,000 unpatched Log4j packages in the Maven Central ecosystem, leaving massive supply-chain risk on the table from Log4Shell exploits.

A critical flaw in a popularly used Java library is being exploited by malicious actors to deliver malware, while security researchers are scanning for vulnerable servers.

Apache Log4j Mitigation Summary Attackers are exploiting a vulnerability in the Log4j logging platform on systems running Apache software that is written in Java and utilizes the log4j library.

Because Log4j is a commonly used Java logging library, this vulnerability could potentially impact all applications and software that implement Java.

Log4j, the popular logging library for Java, will include a number of configuration options that allows it to run in a completely garbage-free manner. The release follows previous attempts to ...

Log4j, an open source project, allows developers to control which log statements are output with arbitrary granularity. It's fully configurable at runtime by using external configuration files ...

It’s a reflection of the fact that the Java programming language is used widely in enterprise software, and for Java software, the Log4j library is exceedingly common.

Caught In The Crosshairs The critical vulnerability disclosed last week in Java logging package Log4j left cybersecurity vendors scrambling to assess their potential exposure.
