Environment

• OS Information: Linux 5.4.0-122-generic #138~18.04.1-Ubuntu SMP Fri Jun 24 14:14:03 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

To Reproduce

cd Hades/plugin/driver/eBPF/
go run .

ATT

Here are some important filters:

1. socket filters
2. pid filters
3. exe/cwd filters

All of the filters should be done in kernel space and interact with userspace by BPF_MAP

Is your feature request related to a problem? Please describe.
Nope

Describe the solution you'd like
compatible vmlinux.h or generate it.

Describe alternatives you've considered
None

Additional context
Git actions added

Let the plugin collector support windows

connect sport & sip are required
icmp required
return value (ret)
honeypot (port scanning)

Is your feature request related to a problem? Please describe.
Nope

Describe the solution you'd like
Test-case for every event and add these into CI/CD

Describe alternatives you've considered

Additional context

sys_enter_execveat: load program: invalid argument: unrecognized bpf_ld_imm64 insn , couldn't load eBPF programs

on kernel 4.19

需要内核支持BTF，感觉在真正使用上不如elf，是准备在低版本内核机器上使用netlink吗？

Ordered msgs in perf_event, add a function to sort the msgs in time order, so that a ppid_argv (parent pid argv) can be done properly

Describe the bug
Incorrect exe in execve(at) event

Environment
5.4.0-104-generic

To Reproduce
Steps to reproduce the behavior:

1. Run Hades
2. Exec command /usr/bin/../bin/whoami

Expected behavior

1. exe should be /usr/bin/whomai

Screenshots

Additional context
Full testcases should be added to avoid such BUG.

Describe the bug
dport always 512 in Centos 8(CORE)

Environment

• OS Information: 4.18.0-348.7.1.el8_5.x86_64

To Reproduce
reverse shell

Expected behavior
port just like we use in the command

In my cloud machine, it spends several minutes to start the ebpfdriver within the cgroups limitation

Describe the bug
fd name by d_dname(just like kernel function does). For now, anonymous pipe is an empty string in Hades while it's pipe[xxxx] in Elkeid. This is very important when we deal with some reverse shell things. We should look into how d_name works in kernel.
But for now, we can still detect the socket...

Screenshots

Describe the bug

1. context->ts, pay attention it's boottime
2. pay attention to the stdin and stdout, dive in to the kernel function which is used in Elkeid.

Steps to reproduce the behavior:

1. Run '...'
2. See error

A clear and concise description of what you expected to happen.

Is your feature request related to a problem? Please describe.
Nope

Describe the solution you'd like
Inspired by tetragon. In Hades, we could integrate dynamic deny policy in peticular fields, like networking, file_opening, etc. with ebpf. Use iptables to implement dynamic network policy even without ebpf for some incident response situtation.

Describe alternatives you've considered

1. bpf_override_return and use the policy with yaml, since it might be complicated
2. lower kernel version, use iptables or something else.

Additional context
Nope

In some situation, udp-related syscall is called very frequently. The kprobe itself may become the limitation of the performace. Let the ebpfmanager unload the probe.

Describe the bug
my env is:
os: ubuntu20.10
kern: 5.8
clang: clang-11

and i try to :make core, it's normally.
but, when i exec: curl www.baidu.com
i can't any dns relative log.

so, can you slove this problem, i think it's a bug.

hope , the bug can be solved soon. thanks!

1. 不知道有没有遗漏，我看网络行为收集都是基于进程FORK/EXEC的，如果进程在运行过程中新增的网络行为是不是检测不到？
2. 维护进程树的考虑主要是啥？

use Ringbuf as default map over kernel version 5.8. Since ringbuf get better performance and ordered the msgs

OS: debian 11
Kernel version: 5.10

Is your feature request related to a problem? Please describe.
Deploy eBPF modules in product env.

Describe the solution you'd like

• Compile .o files for common files or using btfhub.(the two methods are the same, essentially)
• Some suitable distribution and version control, and some CI/CD infras.

Additional context

Describe the bug
hi, i try to run hades. when i operate commands:

sudo ./driver

and, other window : curl www.baidu.com

if it correct, it will appear, dns_data: www.baidu.com

but, the bug happened, it is no data.

so, i hope , the question will solved soon.thanks !

CO-RE support for BTF enabled, just like tracee.
