log4shell - Operational information regarding the log4shell vu

项目说明

Log4shell (C, C, C, C)

This repo contains operational information regarding the Log4shell in the Log4j logging library.
Especially C / C and also covers C / C. For additional information see:

* NCSC-NL ad
* MITRE
* EU CSIRT network members ad, maintained by ENISA
* Log4shell o

For affected organisations and CISOs searching for concise mitigation guidance, the Log4Shell for OES - Full presentation slides for CISOs and techies describes the and explains all steps necessary to successfully mitigate the (patching is not enough).

Repository contents

| Directory | Purpose |
|:-----------------------------------|:--------|
| hunting | Contains info regarding hunting for exploitation |
| iocs | Contains any Indicators of Compromise, such as scanning IPs, etc |
| detection & mitigation | Contains info regarding detection and mitigation, such as regexes for detecting scanning activity and more |
| scanning | Contains references to methods and tooling used for scanning for the Log4j |

| tools | Contains a list of tools for automatically parsing info on this repo |

Please note that these directories are not complete, and are currently being expanded.

NCSC-NL has published a HIGH/HIGH ad for the Log4j . Normally we would update the HIGH/HIGH ad for software packages, however due to the extensi of expected updates we ha a list of known software in the software directory.

Contributions welcome
