A critical cybersecurity vulnerability in the logging software Log4j that was discovered late last week has already resulted in more than 1 million cyberattacks, quickly becoming one of the largest security breaches ever.

We've put together a quick summary of what the issue is, who's affected, and what you can do about it. 


What Is Log4j, And Why Does It Matter?

Log4j is a free, open-source library used by many large organizations—Amazon, Apple, Microsoft, IBM, and Twitter, to name a few—to track user activity across applications. 

The Log4j vulnerability permits hackers to remotely run apps, mine cryptocurrency, install malware, steal sensitive data, or effectively take control of servers that are running a vulnerable version of Log4j and are open to the internet.

Hackers were already actively exploiting the vulnerability at the time of the announcement on Friday, Dec. 10, 2021.


What's Affected By The Log4J Vulnerability?

Many applications that include a management page or web page are affected.

Integrity began addressing the vulnerability on Friday, and we have reviewed the tools we use and applied updates to mitigate these threats.

We are aware of several other applications that are affected, and we are actively patching and scheduling our team members to address these vulnerabilities.
