Threat Glossary

The GalaxyWarden threat glossary

Plain-English explainers on the threats that put your identity, your accounts, and your home at risk — what they are, how attackers use them, and how to protect yourself.

Most attacks begin with data that’s already exposed about you: a reused password in a breach, your address on a data-broker site, your phone number tied to your real name. Learn how the threats work below — then run a free scan to see what’s actually out there about you.

Doxxing→Doxxing is the malicious publication of someone’s private information — home address, phone, workplace, family — to harass or endanger them. Data brokers→Data brokers are companies that collect, aggregate, and sell your personal information — home address, phone, relatives, income — often without your knowledge. People-search site removal→People-search sites publish your home address, phone, and relatives to anyone. Data breach→A data breach is any incident where confidential data — passwords, emails, financial or personal information — is exposed to unauthorized parties. Credential stuffing→Credential stuffing is an automated attack that replays username-and-password pairs stolen in one data breach against hundreds of other sites, exploiting password reuse. Password reuse→Reusing the same password across accounts means one breach can unlock all of them. Phishing→Phishing is a social-engineering attack that tricks you into revealing passwords, codes, or money by impersonating someone you trust. Business email compromise→Business email compromise (BEC) is a targeted scam where attackers impersonate an executive or vendor to trick employees into wiring money or sharing data. SIM swapping→SIM swapping (SIM hijacking) is when an attacker convinces your mobile carrier to move your phone number to their SIM — stealing your calls, texts, and SMS two-factor codes. Two-factor authentication→Two-factor authentication (2FA) adds a second proof of identity beyond your password, so a stolen password alone can’t open your account.
