A Wi-Fi hotspot app exposed more than two million Wi-Fi network passwords from its unprotected database.
The app named WiFi Finder, downloaded by thousands of users to locate and connect with Wi-Fi hotspots, the app also stores Wi-Fi password and credentials.
It allows users to gain unauthorized access to public and private Wi-Fi networks, allowing network owners to offer their Wi-Fi credentials for public connections without prompting them for permission.
According to Techcrunch, the app database leaked more than two million network passwords from its unprotected database.
The records containing the Wi-Fi network name, geolocation, BSSID and the passwords that are stored in plain text. The database was open to anyone, allowing to access the contents and to download in bulk.
According to the app developer, the app only provides the passwords for public hotspots, but the exposed database shows a number of home Wi-Fi network passwords are stored.
The exposure poses a serious threat, an attacker could use the password to gain access to the home network and modify router settings to direct the traffic through malicious servers and exfiltrate sensitive credentials.
Techcrunch learned that the exposed database contains “contact information for any of the Wi-Fi network owners, but the geolocation of each Wi-Fi network correlated on a map often included networks in wholly residential areas or where no discernible businesses exist.”
Wi-Fi access points are the entry point for hackers, setting a week password, default password or sharing the password could compromise network security.
By gaining access to WiFi, hackers can directly access users’ systems and can penetrate further into the network.
