A useful tip for preventing fraud are to not give your personal information away to people who are not authorized to handle it, for example to someone who calls you on the phone and claims to offer you certain goods or services that you never requested. Additionally, be wary of what links you access on the internet, since some people will try to scam you by posting a slightly altered address ("Wal1etHub.com" instead of "Wallethub.com", notice the "1" instead of "l" in the first example) which then feeds your personal information to a scammer rather than the institution you think you're working with.
If you suspect you are a victim of fraudulent activity, please contact your credit reporting agency as soon as possible in order to place a fraud alert on your credit report. You can submit an online request here https://www.transunion.com/fraud-victim-resource/place-fraud-alert.
