Memory improvements (h/t bl4sty)

Memory improvements (fixed segmentation fault) thanks bl4sty for the help.

• Improved interface packet parsing (raised ring buffer size)
• Fixed clearing eBPF objects from queue
• Debugging symbols in boopkit for gdb
• Added -p flag for protect mode (will NOT execute RCE) useful for debugging

v1.4.0 SYN only release

More improvements to code (docs, stability, etc)

• Client now supports -x for SYN only mode (which is what I will use in my demo)

v1.3.0 - Boop default

Boopkit is flipping the logic around. I am trying to move the toolchain to be a little more useful to the end user. By default it will no longer do a reverse dial for an RCE string. It will search for it in the packet buffer, or it will do nothing. However there is a new flag (-r) that can be passed to both the client and the server that will support a reverse dial. A reverse dial is substantially more stable, however has a lot of implications.

v1.2.2 Stability Release

Better packet filtering for -p. Boopkit is now running stable with full RCE using only -p for both the client and the server. Also made improvements to the deep packet inspection mechanism which will increase stability of the rootkit.

v1.2.1

Adding a very important "halt" command.

-9, halt/kill      Halt or kill the boopkit malware on a server.

Running remotely:

[nova@emily]: ~/boopkit>$ sudo -E boopkit-boop -9

v1.2.0 - Single SYN / DPI

A slightly less hacky version of the program. This now supports a "single SYN" mode! There is also a really terrible multithreaded ring buffer for pcap packet captures that probably should never be ran by anyone.

Major features

• -p for "payload-only" mode. This means that boopkit will NOT reverse dial for an RCE payload. It only searches using DPI.
• -c for boopkit-boop commands (moving from -x)
• Dependency on lipcap until we have time for a proper XDP integration. We have an interface for now.
• xCap ring buffer

v1.0.6 Feature Improvements

Mostly a cosmetic and userspace runtime improvement release.

• Now supports home directoy probe loading
• make install now will install to home directory
• Log leaking has been addressed
• Fixed bug with hanging on bad reverse socket calls
• Fixed boop probe memory leak with tplist to generate structs
• Boopscript supports runtime overloading of variables for metasploit

Initial Release

This tag is the first release of boopkit!

• eBPF Probe (Self PID Obfuscation)
• eBPF Probe (TCP Bad checksum)
• eBPF Probe (TCP packet RST)
• Trigger program is compatible with metasploit
• Boopkit has ignore -x feature for noisy localhost
• Boopkit now calling socket directly, preliminary reverse TCP injection

Tested on 5.16 and 5.17 kernels running Archlinux.
