Struggle-Driving – Nonetheless an Straightforward Guess for Family Wi-Fi Assaults | Cyware Alerts

The old-time war-driving method remains to be proving an environment friendly method to crack WiFi passwords. Just lately, a researcher in Israel was capable of crack 70% of WiFi community passwords after gathering community hashes through war-driving.

What’s war-driving?

Struggle-driving is a technique of looking for WiFi networks whereas transferring round in a automobile.

  • On this course of, an individual drives round on native streets and maps residential WiFi networks to seek out any vulnerability to use, akin to widespread or simple to guess passwords. 
  • Software program or instruments for war-driving methods are freely accessible on the web.

The experiment

A researcher from CyberArk got here up with an concept of an experiment after observing that throughout quite a few residences and his neighbors’ WiFi passwords had been truly the cell numbers of the residents or different unsafe passwords.
  • To verify his declare, he collected 5,000 WiFi community hashes by roaming streets with WiFi sniffing gear.
  • After gathering the passwords in a hashed format, he put in a password-recovery software, named Hashcat. This software contains a number of password-cracking strategies akin to masks and dictionary assaults.
  • Utilizing the commonest dictionary, Rockyou[.]txt, he was capable of crack greater than 900 hashes, amounting to three,500 cracked passwords, which is roughly 70% of the hashes gathered.

Extra particulars

In accordance with researchers, the sniffing method used within the experiment solely works with routers supporting roaming options.
  • Roaming routers are often deployed in cities or campuses the place WiFi is deployed as a blanket of web entry utilizing a number of Entry Factors (APs).
  • A lot of the routers include dual-purpose capabilities in order that roaming choices are displayed in APs in residential settings even when their house owners don’t require that performance.
  • This function makes these gadgets susceptible to the dangers of war-driving assaults.


This experiment highlights the dangers of utilizing weak passwords for his or her WiFi entry factors, displaying how simply an attacker can infiltrate a focused community and transfer laterally into it. To remain protected, customers ought to follow utilizing advanced passwords (additionally use a password supervisor) and switch off roaming when not in use.
