CobaltStrike 4.0 - 4.5 Patch

Changed from CSAgent. review by dust-life.

The key for 4.5 is not available here, Just a loader.

features

• Check the file hash from CS official Website
• Patch javaagemt detection
• Patch Authorization
• Patch Checksum8
• Patch profile saving feature, so that your configuration information will not be saved in .aggressor.prop, preventing information leakage by countermeasures.

Just that's all.

Tips - Using jdk8 will make the startup time as long as 10-15s - Versions after using jdk8 will start immediately - If you want to use the checksum8 feature, name the profile c3.profile.
