Bluebugging can vary from one device to another since it depends on inherent vulnerabilities. Some phones or computers that don’t come with Bluetooth protection are more susceptible to attacks.
Typically, bluebugging starts when a hacker attempts to pair with a victim’s device via Bluetooth. Once a connection is established, the hacker installs a backdoor or malware to bypass authentication. The malware is usually designed to gain unauthorized access by exploiting a vulnerability. In some cases, the attacker can compromise a device through a brute-force attack, which entails repeatedly logging in to a victim’s account by randomly guessing username-password combinations. As soon as the hacker gains access, he/she can essentially do what the device owner can, such as reading messages, making calls, or modifying contact details.
