Common Signs Your Data Has Been Compromised
Unexpected Password Resets
Receiving password reset emails you did not request can indicate someone is attempting to access your accounts.
Unfamiliar Charges
Unauthorized transactions on your bank or credit card statements could mean your financial data was exposed.
Strange Account Activity
Logins from unfamiliar locations or devices, or social media posts you did not make.
Spam Increase
A sudden spike in spam or phishing emails often follows an email address appearing in a data breach.
Locked Out of Accounts
Being unable to log into accounts with your correct password may mean an attacker has changed your credentials.
Breach Notification Emails
Companies are often required to notify users when their data is compromised. Take these notices seriously.
Initial Compromise
Attackers exploit a vulnerability, phishing campaign, or insider access to gain entry to a company's systems.
Data Exfiltration
Personal information such as emails, passwords, and financial data is extracted from the company's databases.
Data Sold or Leaked
Stolen data appears on dark web marketplaces or is leaked publicly, accessible to anyone.
Credential Stuffing
Attackers use leaked credentials to attempt logins on other services, exploiting password reuse.
Discovery and Disclosure
The breach is eventually discovered and reported, often weeks or months after the initial compromise.
