There are several ways hackers can hack into an Instagram account, including:

Phishing: where the hacker sends a fake login page to the victim, tricking them into entering their login details.

Brute-force attack: where the hacker uses a computer program to repeatedly try different combinations of username and password until the correct one is found.

Malware: where the hacker infects the victim’s device with malware that allows them to access the victim’s account.

Social engineering: where the hacker tricks the victim into giving them access to their account, often by pretending to be a representative of Instagram or a trusted contact.

Third-party apps: where the hacker uses a third-party app that claims to offer additional functionality for Instagram, but actually uses the victim’s account to post spam or engage in other malicious activities.

It’s important to always be suspicious of links or messages that ask for your personal information, and to never give away your password. Use strong and unique passwords and enable two-factor authentication.
