Is there a free tool to scan for Log4j
the CrowdStrike Archive Scan Tool
The free CrowdStrike tool (dubbed the CrowdStrike Archive Scan Tool, or “CAST”) performs a targeted search by scanning a given set of directories for JAR, WAR, ZIP and EAR files, and then it performs a deeper scan on those file types matching against a known set of checksums for Log4j libraries.
What tool is used to find Log4j
WhiteSource Log4j Detect
WhiteSource says the tool helps developers run quick scans to find vulnerable Log4j versions and seamlessly update them to the latest versions.
Can Log4j be fixed
You can fix the Log4j vulnerability by updating Log4j to the latest version (2.15. 0 or later for CVE-2021-44228 and 2.16. 0 or later for CVE-2021-45046) and applying temporary workarounds if immediate updating is not feasible.
Can I protect myself from Log4j

The vulnerability affects not only Java-based applications and services that use the library directly, but also many other popular Java components and development frameworks that rely on it.
Is Log4j 2.16 still vulnerable
December 20, 2021
Log4j 2.17 has been released to address a Denial of Service (DoS) vulnerability found in v2. 16 and earlier. Log4j 2.16 and earlier does not always protect from infinite recursion in lookup evaluation, which can lead to DoS attacks. This is considered a High (7.5) vulnerability on the CVSS scale.
Does Log4j vulnerability only affect Java
The vulnerability affects not only Java-based applications and services that use the library directly, but also many other popular Java components and development frameworks that rely on it.
How do hackers find zero-day vulnerability
In most cases, hackers use code to exploit zero-day. Sometimes it is discovered by an individual when the program behaves suspiciously, or the developer himself may recognize the vulnerability. Attackers have found a new route by exploiting a zero-day vulnerability in Google's Android mobile operating system.
What tool is used to scan for Log4j vulnerability
