DISCLAIMER: This tool requires tuning and investigative trialling to be truly effective in a production environment. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcNKdHs6efdMp1_GkOPBeDjS_cBKsguCHqtRl5YqGN2qaHgJ9kablCagk9TN6pqDB4zQrMo_65oucXswwH9AU2Ns1Kl66RBa8qDAQOFA93k2e-Xmk33lpT2qdGzhaLWlOm7yggwsdtmtCi60wnUoSncTJSSFxFoLEmPScJJICXIkwpXMFPZj8ARYJ8/w640-h286/sentinel-attack_8_demo.gif OverviewSentinel ATT&CK provides the following tools:

* An ARM template to automatically deploy Sentinel ATT&CK to your Azure environment
* A Sysmon configuration file compatible with Azure Sentinel and mapped to specific ATT&CK techniques
* A Sysmon log parser mapped against the OSSEM data model
* 117 ready-to-use Kusto detection rules covering 156 ATT&CK techniques
* A Sysmon threat hunting workbook inspired by the Threat Hunting App for Splunk to help simplify threat hunts
* A Terraform script to provision a lab to test Sentinel ATT&CK
* Comprehensive guidance to help you use the materials in this repository UsageHead over to the WIKI to learn how to deploy and run Sentinel ATT&CK.

A copy of the DEF CON 27 cloud village presentation introducing Sentinel ATT&CK can be found here and here.

Ecapture : Capture SSL/TLS Text Content Without CA Cert By eBPF

eCapture is a tool to capture SSL/TLS text content without CA cert Using eBPF.How eCapture workshttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhyqHl3BxOoNkTlX0Bdgt5F7ceNM_kEZ5vU52rwVaXetgdvZq9FU4R467ZhGsy2OkTOArTVeRWnl1nwhjKk6otyC5Eg8XCnCpMKW0yV5OBsMlzcXfpIfBlMpT6LB78bZSCcOH45h_JO-AsZDha7a7glA8iYbDMNFgHM0Lo_k6vddKmdTss6CMTjnHgo/s1333/16.png
* SSL/TLS text context capture, support openssl\libressl\boringssl\gnutls\nspr(nss) libraries.
* bash audit, capture bash command for Host Security Audit.
* mysql query SQL audit, support mysqld 5.6\5.7\8.0, and mariadDB. eCapture Architecurehttps://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdiqmWAKH3urE_DuRs_TcPpjh3IyA3uGxurega8lMJ_LHoOy5KZAdy72_KN2AsBECT-gbTkEqALzd0QQRE8VDEkxC3RhN1t5vZJ7dJVjGGrK9JMJmVskV0G2xpEO0C-ZicdVhwObkgt7sQbdwg-7s3D7okFnjk7caoZszp44h9eJrXujD_fpr8G9ek/s1200/ecapture-architecture.png Getting starteduse ELF binary fileDownload ELF zip file release , unzip and use by command ./ecapture --help.

* Linux kernel version >= 4.18
* Enable BTF BPF Type Format (BTF) (Optional, 2022-04-17) check your server BTF configcfc4n@vm-server:~$# uname -r
4.18.0-305.3.1.el8.x86_64
cfc4n@vm-server:~$# cat /boot/config-uname -r | grep CONFIG_DEBUG_INFO_BTF
CONFIG_DEBUG_INFO_BTF=y tls commandcapture tls text context. Step 1:

./ecapture tls –hex

Step 2:

curl https://github.com libressl&boringsslfor installed libressl, libssl.so.52 is the dynamic ssl lib
vm@vm-server:~$ ldd /usr/local/bin/openssl
linux-vdso.so.1 (0x00007ffc82985000)
libssl.so.52 => /usr/local/lib/libssl.so.52 (0x00007f1730f9f000)
libcrypto.so.49 => /usr/local/lib/libcrypto.so.49 (0x00007f1730d8a000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1730b62000)
/lib64/ld-linux-x86-64.so.2 (0x00007f17310b2000)
use the libssl to config the libssl.so path
vm@vm-server:~$ sudo ./ecapture tls –libssl=”/usr/local/lib/libssl.so.52″ –hex
in another terminal, use the command, then type some string, watch the output of ecapture
vm@vm-server:~$ /usr/local/bin/openssl s_client -connect github.com:443
for installed boringssl, usage is the same
/path/to/bin/bssl s_client -connect github.com:443 bash commandcapture bash command.
