In the modern digital world, hacking is no longer a movie scene where someone types green codes on a black screen. It has become a serious threat that affects businesses, governments, and individuals worldwide. Hackers today have access to a wide range of tools—some legal and some illegal—that they use to commit crimes.
This blog explores in detail the most common tools used by hackers, why they use them, and how they work. We’ll also discuss how these tools can be used both for good (by ethical hackers) and for bad (by cybercriminals).
The Dark Side of Hacking
Before we dive into the tools, it’s important to understand that hacking itself isn’t always illegal. Ethical hackers, penetration testers, and cybersecurity researchers also use the same tools—but for defensive purposes.
The real issue begins when these tools are misused for malicious intent: stealing data, spying, scamming, or causing financial loss. Hackers rely on these tools because they make exploitation easier and faster.
Let’s break down the most common categories of tools hackers use to commit crimes.
1. Reconnaissance Tools
Every hack starts with information gathering. Hackers don’t just jump into systems blindly; they first study the target to look for weaknesses.
a) Google Dorking
Hackers use advanced Google search queries (called Google Dorks) to find hidden files, misconfigured servers, or exposed credentials. For example, a single query can reveal login pages, unsecured databases, or even confidential PDFs.
b) Maltego
Maltego is a powerful open-source intelligence (OSINT) tool that hackers use to map relationships between people, domains, emails, and IPs. In the wrong hands, it becomes a weapon for stalking or identifying weak points in a company’s digital footprint.
c) Shodan
Often called the “hacker’s search engine,” Shodan scans the entire internet for connected devices—security cameras, IoT devices, servers, and even traffic lights. Hackers use it to find vulnerable systems that can be hijacked remotely.
2. Password Cracking Tools
Passwords are often the weakest link in security. Hackers use specialized tools to crack them using brute force or dictionary attacks.
a) John the Ripper
This classic tool is used to crack weak passwords by testing millions of combinations. Cybercriminals can gain unauthorized access to accounts once the password is cracked.
b) Hashcat
Known for its speed, Hashcat can use the GPU (graphics card) to break complex password hashes at lightning speed. Hackers often combine it with stolen password databases from data breaches.
c) Hydra
Hydra is designed to perform brute-force attacks on multiple protocols like FTP, SSH, and HTTP logins. If a system uses weak credentials, Hydra can expose them in minutes.
3. Network Scanning and Exploitation Tools
Once hackers know their target, they scan the network for weaknesses and open doors.
a) Nmap
Network Mapper (Nmap) is a legal network scanning tool used for security auditing. However, hackers use it to identify open ports, services running on servers, and possible entry points.
b) Metasploit
Metasploit is one of the most famous hacking frameworks. It contains a library of exploits that hackers can launch against vulnerable systems. With Metasploit, a hacker can turn a small weakness into full system compromise.
c) Angry IP Scanner
This lightweight tool scans IP addresses quickly. Cybercriminals use it to discover live systems that can be targeted for further exploitation.
4. Malware Creation and Deployment Tools
Hacking often involves planting malicious software. Malware comes in many forms—viruses, ransomware, spyware, keyloggers, and trojans.
a) Veil Framework
Hackers use Veil to generate payloads that bypass antivirus software. It’s designed for penetration testing, but criminals abuse it to hide malware in seemingly harmless files.
b) njRAT
This remote access trojan (RAT) allows hackers to fully control a victim’s computer—stealing files, recording keystrokes, or even activating the webcam.
c) DarkComet
Another famous RAT, DarkComet has been used by hackers to spy on victims, steal credentials, and perform large-scale surveillance.
5. Sniffing and Spoofing Tools
Hackers often intercept network traffic to steal sensitive information.
a) Wireshark
A network packet analyzer, Wireshark is widely used by professionals. But hackers misuse it to sniff unencrypted traffic, capturing passwords or session cookies in real time.
b) Cain & Abel
This tool is used for password recovery but has features like ARP spoofing and packet sniffing, which allow hackers to intercept communications.
c) Ettercap
Ettercap enables “man-in-the-middle” attacks, where a hacker places themselves between two communicating parties to intercept or modify data.
6. Phishing and Social Engineering Tools
Technology is only one side of hacking—psychology is the other. Hackers use tools to trick humans into revealing sensitive information.
a) SET (Social Engineering Toolkit)
This toolkit automates phishing attacks, credential harvesting, and website cloning. A criminal can create a fake login page to steal usernames and passwords within minutes.
b) Gophish
An open-source phishing framework that hackers use to send large-scale phishing emails to unsuspecting users.
c) Evilginx2
This advanced phishing tool bypasses two-factor authentication by capturing session tokens. Once a victim logs in, the hacker can hijack the account without knowing the password.
7. Exploitation Kits and Zero-Day Tools
Some hackers go after software vulnerabilities directly.
a) Exploit Kits
These are prepackaged tools sold on the dark web that allow hackers to launch attacks without deep technical knowledge. Common kits include RIG and Angler.
b) Zero-Day Exploits
These are vulnerabilities that software vendors haven’t yet patched. Hackers use secret exploits to silently break into systems, often selling them for huge amounts on underground forums.
8. Denial of Service (DoS) Tools
Hackers also use tools to flood a system or website with traffic, making it unavailable to legitimate users.
a) LOIC (Low Orbit Ion Cannon)
LOIC is a simple but powerful tool that allows hackers to launch DDoS attacks by overwhelming a target server with requests.
b) HOIC (High Orbit Ion Cannon)
An advanced version of LOIC, HOIC can generate more powerful distributed denial-of-service (DDoS) attacks.
c) Botnets
Hackers infect thousands of devices with malware and control them as a network (botnet). These botnets can unleash devastating attacks against websites and critical infrastructure.
9. Data Exfiltration Tools
Stealing data is often the ultimate goal of hackers.
a) Mimikatz
A post-exploitation tool that extracts stored passwords, hashes, and PINs from Windows systems. Hackers use it to escalate privileges and move deeper into a network.
b) Netcat
Often called the “Swiss Army knife of networking,” Netcat can create backdoors, transfer files, and listen to traffic—all useful for hackers trying to steal data.
c) Rclone
Hackers use Rclone to exfiltrate data to cloud services like Google Drive or Dropbox without triggering alarms.
10. Dark Web Tools
Once data is stolen, hackers often sell it or use underground services.
a) Tor Browser
Tor allows hackers to remain anonymous online. They use it to access the dark web where stolen data, exploits, and hacking tools are traded.
b) Cryptomixers
To hide illegal money made from hacking, criminals use Bitcoin mixers or tumblers that scramble cryptocurrency transactions.
c) Dark Web Marketplaces
Platforms like Hydra or AlphaBay (now shut down) allowed hackers to buy and sell everything—from stolen credit cards to ransomware kits.
Why Hackers Use These Tools
Hackers don’t always build everything from scratch. Most tools are available freely online, either as open-source software or leaked versions. The reasons they use these tools are:
- Efficiency: Automates attacks that would otherwise take months.
- Accessibility: Many are free or cheap to get.
- Anonymity: Allows attackers to remain hidden.
- Scalability: Enables mass attacks across thousands of targets.
Ethical Use vs Criminal Use
The same tools that hackers use for crime are also used by cybersecurity professionals. For example:
- A penetration tester might use Nmap to find open ports in a company’s system—but report it responsibly.
- A forensic investigator might use Wireshark to analyze network traffic after a breach.
- Security researchers might use Metasploit to test patches against real-world attacks.
The difference lies in intent.
Protecting Yourself From Hacker Tools
So, how can individuals and businesses protect themselves from these tools?
- Strong Passwords: Use long, complex, and unique passwords.
- Two-Factor Authentication: Adds an extra layer even if your password is stolen.
- Regular Updates: Keep your software and systems patched.
- Firewalls & IDS/IPS: Monitor and block suspicious traffic.
- Employee Training: Prevent phishing by educating users.
- Encryption: Protect sensitive data in case it’s intercepted.
- Threat Monitoring: Use advanced security tools to detect unusual activity.
Conclusion
Hackers have a wide arsenal of tools at their disposal—ranging from simple password crackers to advanced malware kits. While many of these tools are designed for ethical and educational use, in the wrong hands they can wreak havoc on individuals, businesses, and governments.
Understanding what these tools are, how they work, and why hackers use them is the first step in defending against cybercrime.
The best defense is awareness, strong security practices, and constant vigilance. In today’s world, it’s not about if hackers will try to attack—it’s about when.
