Cybercrime takes many forms. Identity theft occurs when criminals steal personal information like Social Security numbers, bank account details, or credit card information to commit fraud. Phishing involves fraudulent emails or messages designed to trick people into revealing sensitive information or downloading malware. Ransomware attacks encrypt a victim's files and demand payment for their release. Hacking refers to unauthorized access to computer systems or networks. Online harassment and cyberstalking involve repeated threatening or abusive messages sent through digital platforms.
Other common cybercrimes include romance scams, where criminals build fake relationships to extract money; tech support scams, where fraudsters convince people their devices are infected; and business email compromise, where attackers impersonate company executives to authorize fraudulent wire transfers. The FBI notes that scammers stole approximately $1.14 billion through romance scams alone in 2023.
Ransomware attacks against hospitals, schools, and government agencies have increased significantly. In 2023, healthcare facilities reported numerous attacks disrupting patient care. Local governments also faced substantial attacks, with some cities paying millions in ransom payments.
Understanding these crime types helps you recognize when you or your organization may be a victim. Different crimes require different reporting procedures and evidence collection methods.
Practical Takeaway: Keep a record of any suspicious online activity you notice, including the dates, times, email addresses, phone numbers, or account names involved. This information will be valuable if you decide to report the incident.
Detecting cybercrime victimization early can limit damage and provide authorities with information needed for investigation. Warning signs vary depending on the type of crime, but certain indicators suggest something suspicious has occurred.

If you notice unauthorized charges on your bank or credit card statements, this may indicate identity theft or payment card fraud. Missing statements or bills that normally arrive may signal that a criminal has changed your mailing address. Receiving bills for accounts you did not open suggests someone opened fraudulent accounts in your name. Credit score drops without explanation can indicate unauthorized credit inquiries or new accounts.
For email and account security, unexpected password reset confirmations you did not request indicate someone accessed your account. Emails from services you do not use suggest an account was created with your information. Friends receiving messages from your social media accounts that you did not send means your account was compromised. Pop-ups, slower computer performance, or unusual error messages may indicate malware infection.
Phone-related warning signs include calls from creditors about debts you did not incur, strange charges on your phone bill, or unexpected loss of phone service. Receiving mail for credit cards you did not apply for signals potential identity theft. Getting called by banks about accounts you do not recognize also warrants investigation.
The Federal Trade Commission (FTC) reports that identity theft was the most common fraud reported by consumers, with 2.6 million fraud reports filed in 2023. However, many victims do not discover the crime immediately. Some identity theft victims report the fraud only when filing taxes and discovering that someone already claimed their information.
Trust your instincts. If something feels wrong with your accounts or communications, it probably warrants investigation.
Practical Takeaway: Regularly review your bank and credit card statements for unauthorized transactions. Check your credit reports annually through annualcreditreport.com, which provides one free report per year from each of the three major credit bureaus.
Multiple government agencies investigate cybercrime, and the appropriate agency depends on the crime type and scope. Understanding which agency investigates which crimes helps you report to the right place.

The Internet Crime Complaint Center (IC3), operated jointly by the FBI and the National White Collar Crime Center, serves as the primary national reporting system for cybercrimes. IC3 accepts complaints about internet-based crimes and forwards information to law enforcement agencies for investigation. Victims can file reports at ic3.gov at no cost. The FBI's Internet Crime Complaint Center receives complaints about phishing, ransomware, business email compromise, identity theft, and countless other cybercrimes.
The Federal Trade Commission (FTC) investigates consumer fraud and identity theft. Consumers can report cybercrime directly to the FTC at reportfraud.ftc.gov. The FTC maintains a database of fraud complaints that helps identify crime patterns. Unlike law enforcement agencies, the FTC primarily focuses on protecting consumers and businesses rather than prosecuting individual perpetrators, though they may refer serious cases to prosecutors.
The FBI field offices across the United States accept cybercrime complaints, particularly those involving significant financial loss, national security implications, or organized crime. You can locate your local FBI office at fbi.gov. The Cybercrime Division of the FBI specifically targets large-scale cybercrimes affecting national interests.
Local law enforcement agencies, including police and sheriff departments, investigate cybercrimes within their jurisdictions. Many departments have dedicated cybercrime units or specialized investigators. The Secret Service, which protects the president, also investigates financial crimes including counterfeit currency and identity theft. Immigration and Customs Enforcement (ICE) investigates crimes with international implications.
State attorneys general offices maintain consumer fraud divisions that handle cybercrime complaints. The Consumer Sentinel Network connects the FTC, state attorneys general, and law enforcement agencies to share complaint data about fraud.
Practical Takeaway: For most cybercrimes, start by reporting to the IC3 at ic3.gov or to the FTC at reportfraud.ftc.gov. For crimes involving significant financial loss or national security concerns, contact your local FBI field office.
Reporting cybercrime online involves providing detailed information about the incident to law enforcement or consumer protection agencies. The process varies slightly between agencies, but certain steps apply to most reporting platforms.

To report through the Internet Crime Complaint Center, visit ic3.gov and click on the "File a Complaint" link. The system asks for your contact information, including your name, address, phone number, and email address. You then provide details about the complaint, including what happened, when it happened, and how much money was involved if applicable. IC3 requests information about the perpetrator, such as email addresses, website addresses, social media accounts, or phone numbers used in the crime.
For identity theft reports, the FTC's system at identitytheft.gov walks you through creating a recovery plan specific to your situation. You report the identity theft details and the system provides a customized recovery plan with steps for contacting creditors, placing fraud alerts, and monitoring your accounts. The FTC then sends you a report you can provide to creditors and financial institutions.
When reporting through the FTC's general fraud reporting system at reportfraud.ftc.gov, you describe the fraud, provide the scammer's contact information, and detail any money sent or personal information shared. The system allows you to upload supporting documents like emails or screenshots.
Most online reporting systems ask you to provide specific details: what happened, when it happened, how you were contacted by the scammer, what information or money was involved, and how you discovered the crime. Save emails, screenshots, transaction records, and any other evidence. Many systems allow you to attach files to your report.
After submitting your report, you receive a confirmation number or complaint ID. Save this number for your records. It helps if law enforcement contacts you with questions or if you need to reference the report later. The FBI estimates that it takes time for investigators to review complaints, so do not expect immediate response.
Practical Takeaway: Before filing your report, gather all relevant information: email addresses, IP addresses, phone numbers, transaction details, and copies of messages. Having everything organized makes reporting faster and more complete.
Law enforcement agencies need thorough documentation to investigate cybercrime effectively. Gathering and preserving evidence correctly helps investigators track perpetrators and prosecute crimes.
