介绍

eCapture旁观者无需CA证书,即可抓HTTPS/TLS明文数据 !

eCapture旁观者是什么?

eBPF HOOK uprobe实现的各种用户态进程的数据捕获,无需改动原程序。 也可以导出为pcap-NG格式的数据包,使用wireshark打开。 支持 Linux/Android 两种操作系统,支持x86_64、aarch64两种CPU架构。

  • SSL/HTTPS数据导出功能,针对HTTPS的数据包抓取,不需要导入CA证书。
  • bash的命令捕获,HIDS的bash命令监控解决方案。
  • mysql query等数据库的数据库审计解决方案。

为什么选择eCapture?

Wireshark、tcpdump等工具,只能抓到加密后的流量,无法捕获TLS的明文。eCapture只需要root权限,即可捕获明文的HTTPS通信包明文。

如何使用

下载

open https://github.com/gojue/ecapture/releases , and choose your version.

  • Linux、Android ARM64-aarch64 CPU架构,内核版本 >= 5.5 , ecapture-v0.8.0-linux/android-arm64.tar.gz
  • Linux/Android X86_64 CPU架构,内核版本 >= 4.18 , ecapture-v0.8.0-linux/android-amd64.tar.gz

运行

./ecapture 

参数

cfc4n@vmserver:~/$ sudo ecapture -h
NAME:
	ecapture - capture text SSL content without CA cert by ebpf hook.

USAGE:
	ecapture [flags]

VERSION:
	linux_arm64:v0.8.0:5.15.0-105-generic

COMMANDS:
	bash		capture bash command
	gnutls		capture gnutls text content without CA cert for gnutls libraries.
	gotls		Capturing plaintext communication from Golang programs encrypted with TLS/HTTPS.
	help		Help about any command
	mysqld		capture sql queries from mysqld 5.6/5.7/8.0 .
	nss		capture nss/nspr encrypted text content without CA cert for nss/nspr libraries.
	postgres	capture sql queries from postgres 10+.
	tls		use to capture tls/ssl text content without CA cert. (Support openssl 1.0.x/1.1.x/3.0.x or newer).

DESCRIPTION:
	eCapture(旁观者) is a tool that can capture plaintext packets
	such as HTTPS and TLS without installing a CA certificate.
	It can also capture bash commands, which is suitable for
	security auditing scenarios, such as database auditing of mysqld, etc (disabled on Android).
	Support Linux(Android)  X86_64 4.18/aarch64 5.5 or newer.
	Repository: https://github.com/gojue/ecapture
	HomePage: https://ecapture.cc
	
	Usage:
	  ecapture tls -h
	  ecapture bash -h

OPTIONS:
  -b, --btf=0		enable BTF mode.(0:auto; 1:core; 2:non-core)
  -d, --debug[=false]	enable debug logging.(coming soon)
  -h, --help[=false]	help for ecapture
      --hex[=false]	print byte strings as hex encoded strings
  -l, --logaddr=""	-l /tmp/ecapture.log or -l tcp://127.0.0.1:8080
      --mapsize=1024	eBPF map size per CPU,for events buffer. default:1024 * PAGESIZE. (KB)
  -p, --pid=0		if pid is 0 then we target all pids
  -u, --uid=0		if uid is 0 then we target all users
  -v, --version[=false]	version for ecapture
