This page explains how hackers operate to help you better protect yourself. Any malicious use is strictly prohibited.

PASS WIFI

WiFi password recovery method:

  1. Download the app via: https://www.passwordrevelator.net/en/passwifi
  2. Launch a scan of available WiFi networks around you
  3. The tool analyzes access points and displays the passwords

Note: This analysis can be performed on all detected WiFi networks.

Hack WiFi network passwords

Why are WiFi networks vulnerable?

Wireless networks present several exploitable weaknesses:

  • Public radio transmission: Data travels through the air, accessible to anyone nearby
  • Default configurations: Factory admin passwords and SSIDs often unchanged
  • Outdated protocols: WEP and WPA1 still used on some networks
  • WPS vulnerabilities: Weaknesses in the simplified pairing system
  • Extended range: WiFi signals often extend beyond physical boundaries

Advanced WiFi hacking techniques

1. Dictionary and brute force attacks

Massive password-guessing attempts using predefined lists.

Attack mechanism:

  • Capture of the authentication handshake
  • Use of specialized WiFi wordlists
  • Offline attack on the captured handshake
  • Leveraging GPU computing power

2. WPS vulnerability exploitation

Attack on the vulnerable WiFi Protected Setup (WPS) system.

Attack process:

  • Detection of access points with WPS enabled
  • Brute-force attack on the WPS PIN
  • Recovery of the WPA/WPA2 key via compromised PIN
  • Complete bypass of the password

3. Evil Twin attacks

Creation of malicious access points mimicking legitimate networks.

Techniques used:

  • Creation of an SSID identical to a trusted network
  • Stronger signal to attract connections
  • Deauthentication of legitimate clients
  • Capture of credentials during reconnection

4. WEP attacks

Exploitation of cryptographic flaws in the obsolete WEP protocol.

Compromise process:

  • Mass collection of IV (Initialization Vector) packets
  • Exploitation of RC4 algorithm weaknesses
  • Packet injection to accelerate data collection
  • Key recovery via statistical analysis

5. KARMA and MANA attacks

Exploitation of probe requests and remembered networks.

Methodology:

  • Listening to devices' probe requests for known networks
  • Automated creation of matching rogue access points
  • Automatic connection by pre-configured devices
  • Interception of unencrypted traffic

6. Deauthentication attacks

Sending deauthentication packets to disrupt the network.

Exploitation scenarios:

  • Mass deauthentication of a specific client
  • Forced disconnection to capture the handshake
  • Denial-of-service on the target network
  • Facilitation of other attack types

Advanced WiFi protection strategies

1. Strong cryptographic configuration

  • Use only WPA3 or WPA2 with AES
  • Fully disable WPS on your router
  • Completely avoid WEP and WPA1 protocols
  • Use a complex pre-shared key (20+ characters)
  • Periodically rotate encryption keys

2. Access point hardening

  • Change default admin credentials
  • Disable remote management
  • Regularly update router firmware
  • Use MAC address filtering if needed
  • Reduce WiFi transmission power

3. Monitoring and detection

  • Regularly monitor connected devices
  • Detect rogue access points
  • Analyze connection logs
  • Use intrusion detection tools
  • Enable alerts for suspicious activity

4. Network segmentation

  • Create separate guest networks
  • Isolate IoT devices on a dedicated VLAN
  • Separate main network from guest network
  • Restrict inter-network communication
  • Configure appropriate firewall rules

5. Advanced security policies

  • Hide SSID if necessary (security through obscurity)
  • Disable unnecessary services (UPnP, Telnet)
  • Set time-based access schedules
  • Limit the number of simultaneous connections
  • Use RADIUS authentication for enterprises

6. Client-side protection

  • Disable auto-connect to open networks
  • Always use a VPN on public networks
  • Lock down device network settings
  • Train users on WiFi risks
  • Update WiFi drivers regularly

7. Regular security auditing

  • Perform periodic WiFi penetration tests
  • Verify signal coverage boundaries
  • Analyze router vulnerabilities
  • Review security configurations
  • Update security policies

What to do if your WiFi is compromised?

Immediate actions to take:

  1. Immediately change your WiFi password to a new complex key
  2. Change your router’s admin credentials to prevent re-compromise
  3. Review the list of connected devices and ban unknown ones
  4. Analyze router logs to identify the attack origin
  5. Update your router firmware to the latest version
  6. Review all security settings and disable unused services
  7. Monitor your network traffic for suspicious activity
  8. Consider replacing hardware if the breach is long-standing

FAQ – Frequently Asked Questions about WiFi Security

Does hiding the SSID provide real protection?

No—it’s security through obscurity. The SSID appears in probe requests and can be easily discovered with network analysis tools.

Is WPA3 truly unbreakable?

WPA3 is a significant improvement but not invulnerable. It protects against certain attacks but remains susceptible to specific threats like downgrade attacks.

How can I tell if my WiFi has been hacked?

Warning signs: unexplained network slowdowns, unknown devices in the connection list, unauthorized configuration changes.

Are enterprise networks more secure?

Yes—thanks to 802.1X authentication with certificates and RADIUS servers, offering far superior security than pre-shared keys.
