Who developed Log4j
the Apache Software Foundation
Apache Log4j is a Java-based logging utility originally written by Ceki Gülcü. It is part of the Apache Logging Services, a project of the Apache Software Foundation. Log4j is one of several Java logging frameworks. Gülcü has since created SLF4J, Reload4j, and Logback which are alternatives to Log4j.
How was Log4j fixed
Since December, most vendors have published security updates that resolve the Log4j flaw within their applications, and Apache themselves have released fixes and updated versions that remediate the vulnerability. With that being said, thousands of systems are still vulnerable today.

Who got hacked by Log4j
Symantec said an unnamed engineering company with energy and military customers was hacked by the North Korean government using the Log4j vulnerability.
Who found the vulnerability
Some vulnerabilities are discovered by 'white hat' security researchers, who usually report the issue to the software vendors through established bug bounty programs (such as our Vulnerability Reward Program). Others are found by attackers, who put their discoveries to more harmful use.
Who attacked Log4j
Attacks exploiting the Log4j vulnerability appear to have been limited to Minecraft servers until the issue was made public by Apache on December 9, 2021.
Is log4j still a threat
Log4j remains a threat in 2023
The highest concentration of critical findings linked to Log4j were found within the first 48 hours of the vulnerability becoming known. At the time, findings often originated in the core of an application and later findings migrated to the dependences those applications rely on.
Was log4j a zero day
Log4j is just a recent zero-day attack example. There have been many in the past. Many more will no doubt happen in the future.
Where was Log4j discovered
Log4j origins
In late November, during the Thanksgiving holiday weekend in the U.S., Chen Zhaojun, a member of the Alibaba Cloud Security Team discovered the Log4j vulnerability and alerted the Apache Software Foundation.
Was Log4j discovered in Minecraft
Many services and applications rely on Log4j, including games like Minecraft, where the vulnerability was first discovered.

Who hacked first
John Draper, also known as Captain Crunch, is often named as the first ever hacker. And rather than having lots of high-tech hacking tools at his disposal, he managed to do it all with a toy whistle from a cereal packet.
How was the vulnerability detected
Vulnerability detection is the identification of software vulnerabilities across your systems. It identifies what the weaknesses are in the environment. These might be detected via database scans, application scans, host-based scans, and other scans.
Who discovered hackers
In the mid-1900s, the term hacking began at MIT and actually started with train sets, not computers. Students at the prestigious institution started altering train sets and these individuals became known as hackers.
Is Log4j safe again
The widespread vulnerability that first appeared in Apache Log4j in 2021 will continue to be exploited, potentially even in worse ways than we've seen to date. The more worrisome aspect of these threats is that there's a good chance they'll continue to be exploited months or years into the future.
Has anyone exploited Log4j
Log4j, a piece of software used across corporate, consumer and industrial networks has a major flaw hackers are exploiting. A flaw in widely used internet software known as Log4j has left companies and government officials scrambling to respond to a glaring cybersecurity threat to global computer networks.
Who hacked Log4j
APT35 is one of several state-backed hacking groups known to have been developing tools to exploit public-facing Java applications that use vulnerable versions of the Log4j error-logging component.
Who is the world most number 1 hacker
Kevin Mitnick holds the title as the world's most famous hacker ever, with this title dating back to 1995 by the US Department of Justice. Kevin Mitnick started hacking at an early age.
Who is the king of hackers
Kevin Mitnick is the world's authority on hacking, social engineering, and security awareness training. In fact, the world's most used computer-based end-user security awareness training suite bears his name.
Who discovered vulnerability
Some vulnerabilities are discovered by 'white hat' security researchers, who usually report the issue to the software vendors through established bug bounty programs (such as our Vulnerability Reward Program). Others are found by attackers, who put their discoveries to more harmful use.
How do attackers find vulnerabilities
Scanning can be considered a logical extension (and overlap) of active reconnaissance that helps attackers identify specific vulnerabilities. It's often that attackers use automated tools such as network scanners and war dialers to locate systems and attempt to discover vulnerabilities.
