案例一:Docker容器痕迹清除#
场景:红队需要在Docker容器中清除攻击痕迹,避免被发现。
解决方案:使用多种Docker痕迹清除技术。
实施步骤:
清除容器日志:
# 查看容器日志 docker logs container_name # 清除容器日志 docker logs --tail 0 -f container_name # 删除容器日志文件 docker inspect container_name | grep LogPath rm -rf /var/lib/docker/containers/container_id/container_id-json.log清除容器历史:
# 删除已停止的容器 docker container prune # 删除所有容器 docker rm -f $(docker ps -aq)清除容器临时文件:
# 清除临时文件 docker exec -it container_name /bin/bash rm -rf /tmp/* rm -rf /var/tmp/*
结果:
- 成功清除了Docker容器中的攻击痕迹
- 删除了所有可疑的日志文件
- 清除了所有临时文件
- 降低了被发现的风险
案例二:Kubernetes痕迹清除#
场景:红队需要在Kubernetes环境中清除攻击痕迹,避免被发现。
解决方案:使用Kubernetes痕迹清除技术。
实施步骤:
清除Pod日志:
# 查看Pod日志 kubectl logs pod_name # 清除Pod日志 kubectl logs pod_name --tail=0清除Pod历史:
# 删除Pod kubectl delete pod pod_name # 删除所有Pod kubectl delete pods --all --all-namespaces清除Kubernetes事件:
# 查看Kubernetes事件 kubectl get events --sort-by='.lastTimestamp' # 清除Kubernetes事件 # Kubernetes事件会自动清理,但可以加速清理过程
结果:
- 成功清除了Kubernetes环境中的攻击痕迹
- 删除了所有可疑的Pod日志
- 清除了所有Kubernetes事件
- 降低了被发现的风险
案例三:容器环境APT痕迹清除#
场景:红队需要在容器环境中实施高级持续性威胁(APT)痕迹清除,确保长期不被发现。
解决方案:使用APT痕迹清除框架。
实施步骤:
清除初始访问痕迹:
# 清除初始访问痕迹 apt_cleaner.clean_initial_access_traces()清除横向移动痕迹:
# 清除横向移动痕迹 apt_cleaner.clean_lateral_movement_traces()清除持久化痕迹:
# 清除持久化痕迹 apt_cleaner.clean_persistence_traces()实施反取证技术:
# 实施反取证技术 apt_cleaner.implement_anti_forensics()
结果:
- 成功实施了APT痕迹清除
- 清除了所有攻击痕迹
- 实施了反取证技术
- 确保了长期不被发现
