| CVE identifier(s) | CVE-2021-44228 |
|---|---|
| Date discovered | 24 November 2021 |
| Date patched | 6 December 2021 |
| Discoverer | Chen Zhaojun of the Alibaba Cloud Security Team |
| Affected software | Applications logging user input using Log4j 2 |
How is Log4j vulnerability detected
Log4j will first log messages in software, then scan them for errors. Its logging capabilities allow it to communicate with other internal functions on systems, such as directory services. This creates the opening for the vulnerability.

Where was Log4j exploit 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.
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.
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.
How did they find log4j
The vulnerability was first discovered in a version of the game Minecraft. Malicious individuals learned that the game's chat was being logged using Log4j and, if they entered malicious code into the chat, it led to remote code execution (RCE).
Which company 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.
Who exploited Log4j
UPDATE: On November 16, the Cybersecurity and Infrastructure Security Agency (CISA) announced that government-sponsored actors from Iran used the Log4j vulnerability to compromise a federal network, deploy Crypto Miner and Credential Harvester.
When was Log4j first detected
Log4j was discovered on December 9, 2021, leaving many cybersecurity professionals working 40-plus hour weeks through the end of the year to assess their environments and coordinate remediation efforts across their organizations.
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.
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.
Who built 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.
Was Log4j discovered in Minecraft
Many services and applications rely on Log4j, including games like Minecraft, where the vulnerability was first discovered.
How was Log4j exploit discovered
The vulnerability was first discovered in a version of the game Minecraft. Malicious individuals learned that the game's chat was being logged using Log4j and, if they entered malicious code into the chat, it led to remote code execution (RCE).

Who is the top 1 most hacker in the world
Kevin Mitnick
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.
How did they find Log4j
The vulnerability was first discovered in a version of the game Minecraft. Malicious individuals learned that the game's chat was being logged using Log4j and, if they entered malicious code into the chat, it led to remote code execution (RCE).
Who finds vulnerabilities
Vulnerabilities usually arise when a researcher or attacker discovers that part of a program's code can be forced to run in an unexpected way, which results in undesirable behavior.
How are cyber attacks detected
Other key threat detection strategies include: Penetration testing. By thinking the way a cyber criminal would, security experts can scan their IT environments for vulnerabilities, such as unpatched software, authentication errors, and more.

Who creates a CVE for vulnerability
The Mitre Corporation
CVEs are assigned by a CVE Numbering Authority (CNA). While some vendors acted as a CNA before, the name and designation was not created until February 1, 2005. there are three primary types of CVE number assignments: The Mitre Corporation functions as Editor and Primary CNA.
