What is the first thing you do when you get hacked on Facebook?
Should you harbor suspicions that your Facebook account has fallen prey to malicious activity, your immediate priority must be to alter your password without delay and promptly reach out to the Facebook Help Center at 1-877-646-4023. This swift action is pivotal to reclaiming control over your account and thwarting any further unauthorized access.

If the intruder has already modified your password and you’re unable to log in, utilize the "Forgot Password" feature to initiate a reset. Once your account is secured, scrutinize recent activity to identify any anomalies and activate two-factor authentication to fortify your account with an additional layer of protection.

Additionally, report the breach to Facebook through the Help Center (1-877-646-4023) by selecting the "Hacked Accounts" option within the "Security" section. You might be prompted to verify your identity, modify your password, and meticulously examine suspicious activities tied to your account.

Acting with immediacy is paramount; changing your password and contacting the Facebook Help Center (1-877-646-4023) are foundational steps to reinstating your account's integrity. This is particularly crucial if the intruder has not yet completely seized control of your access.”
