# pspy64 工具 - Linux 权限提升
## 这是什么
当以 root 身份运行的周期性任务执行可写脚本、不安全的相对路径或存在漏洞的处理器时，Cron 任务会创建提权路径。关键在于证明低权限用户能够控制某个特权计划任务将要运行的东西。本页具体关注 **pspy64 工具** 并保持利用流程切合实际：识别条件，安全验证，然后运行证明影响所需的最小载荷。
## 枚举
在运行利用路径之前，先确认本地上下文和具体的错误配置。
```bash
cat /etc/crontab
ls -la /etc/cron.*
systemctl list-timers --all
```
## 示例
## pspy64 工具
该工具 [pspy64](https://github.com/DominicBreuker/pspy/releases) 会自动检测 cron 任务。 **Pspy** 是一个命令行工具，用于监控 Unix/Linux 系统中在后台运行的任务，并显示正在启动的新任务。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/zh/privesc/cron-jobs/pspy64-cron-enumeration-linux-privilege-escalation.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
