Log4j Vulnerability: Realize the risks associated and steps to protect your enterprise systems

Recently, a threat in the internet software called Log4j vulnerability, which has put millions of devices at risk, has been identified as one of the worst cybersecurity threats in the digital space. Unfortunately, this will more likely affect the open-source logging library used in most enterprise applications, embedded systems, and sub-components. The crisis level is high since Log 4j, a Java library, is used widely, even by the United States Cybersecurity and Infrastructure Security Agency. Therefore, the hackers can find this situation as an opportunity to penetrate in to millions of networks globally.

Major Technology providers affected by Log4j vulnerability

Technology giants such as IBM, Apple Inc, Amazon, Cloudflare, and Microsoft are on the growing list. Many organizations realized the risks and have issued warnings and assistance to customers. They also have given guidance to minimize the risks.

Threats enterprises can expect from Log4j Vulnerability

Security leaders are specifically concerned that the vulnerability may allow hackers to install ransomware and malware. It opens the way for hackers to control the java-based web servers. Reports says, the exploits also include hacking computing power to mine cryptocurrency and mass-scanning servers. Successful exploitation of this vulnerability could expose critical data. In a nutshell, the flaw allows untrusted data to manipulate the server’s actions.

Actions to be taken to fix the Log4j vulnerability

Security teams need to engineer patches of the issues before the exploit happens. Identify potential areas to deploy fixes on immediate priority. Begin with a complete audit of every application, website, and network that is public-facing and update all affected systems with patched versions. In addition, teams should take immediate measures to secure companies’ sensitive data and access credentials.  IT teams should analyze the codes written in Java in their network and validate whether they use the Log 4j library, and update it immediately. In addition, teams should take immediate care to secure companies’ sensitive data and access credentials.

On the Whole,

The Log4j vulnerability is a highly impacted threat that hackers can easily exploit. This vulnerability needs a proactive approach and a “What next” mindset to ensure clean prevention. You are already secured if your applications, servers, and gateways are updated with automatic new protections. However, cybersecurity experts recommend IT and Security teams to take immediate actions on the matter.


The vulnerability in a library called Log4j that opens the door for arbitrary code execution is the recent threat identified by the experts. This is serious because it can bypass security data and do things that the admin does not want to do.

There are six custom-level logging in Log4j that includes TRACE, DEBUG, INFO, WARN, ERROR, and FATAL. If a log level is set, messages will be logged for that level and level below it.

Log4j is an open-source logging library commonly used by apps and services across java-based web applications. Unfortunately, as this is a very old library found in most Java-based applications, hackers find that easy to break into systems and steal data.

Log4j vulnerability can be identified by running a simple security scan through threat tracking applications or identifying which part of the application is not up-to-date.

Yes, Log4j is a threat as it can steal or corrupt an organization’s sensitive data and harm the systems.

  1. Running a security scan
  2. Making all the applications up-to-date 
  3. Pushing new security patch updates

A common and widely used library in java-based web applications is Log4j, and the vulnerability in Log4j has been named Log4Shell.

The challenge here is identifying Log4j because of the way Java packages libraries. The Log4j will be hiding somewhere in their application where even the experts find it difficult to trace.
