旁观者 - eBPF技术强力驱动,无需CA证书即可捕获HTTPS/TLS明文数据包。 | eCapture

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。

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.
