 By default, **linpeas won't write anything to disk and won't try to login as any other user using `su`**.
 
+LinPEAS keeps expanding vendor-specific coverage; as of 29-Nov-2025 it warns when IGEL OS appliances still ship the SUID `setup`/`date` helpers that allow NetworkManager/systemd configuration hijacking (Metasploit module `linux/local/igel_network_priv_esc`).

 By default linpeas takes around **4 mins** to complete, but It could take from **5 to 10 minutes** to execute all the checks using **-a** parameter *(Recommended option for CTFs)*:
 - From less than 1 min to 2 mins to make almost all the checks
 - Almost 1 min to search for possible passwords inside all the accesible files of the system

+# Title: Interesting Permissions Files - IGEL OS SUID setup/date abuse

+# Author: HT Bot
+# Last Update: 29-11-2025
+# Description: Detect IGEL OS environments that expose the SUID-root `setup`/`date` binaries and highlight writable NetworkManager/systemd configs that enable the documented privilege escalation chain (Metasploit linux/local/igel_network_priv_esc).
