Recognizing and Avoiding Common Scams
Protecting yourself begins with being able to identify and avoid common deceptive techniques.
Phishing, Smishing, and Vishing
These are social engineering attacks designed to trick you into giving up sensitive information, such as passwords, credit card numbers, or other personal data.
Attack Type | Method | Key Warning Signs |
Phishing | Phishing is an attempt to steal your personal information through email. While often designed to look like they come from a legitimate company or person, phishing emails contain these signs that you should look out for. Common red flags of a phishing email include:
To protect yourself:

Smishing | SMS/Text Message | Be wary of Smishing, which involves scammers sending fraudulent SMS messages from fake phone numbers or URLs. These messages often share a tone of urgency, similar to other scams, typically claiming unexpected prizes, urgent account issues (like a locked account), or requesting immediate action. To protect yourself:
|
Vishing | Phone Call | Vishing is a tactic where fraudsters use automated voice calls to report urgent account problems and attempt to extract account information from users. To protect yourself:
|
Best Practice: Never click on suspicious links, open unexpected attachments, or provide personal information over the phone unless you initiated the contact and are certain of the recipient's identity. If in doubt, contact the company or organization through their official website or phone number.
Device and Operating System Protection
Keeping your devices secure is fundamental to protecting your data. This applies to mobile, Mac, and Windows operating systems.
General Malware and Malicious App Protection
Recommendation | Details |
Keep Software Updated | Enable automatic updates for your operating system and all applications. Updates often include critical security patches. |
Use Strong Authentication | Prioritize security by enabling multi-factor authentication (MFA) on all available accounts. Implement strong, unique passwords or passphrases for all logins, utilizing Passkeys when supported. For MFA, use dedicated authenticator applications like Authy, Google Authenticator, or Auth0 Guardian, as they offer a more secure method than relying on Email or SMS verification. |
Install Anti-Malware Software | Use reputable anti-malware or endpoint protection software on Windows and Mac devices. |
Back Up Data | Regularly back up important data to a secure, external source or cloud service. |
Enable Firewalls | Ensure your operating system's built-in firewall is enabled on Mac and Windows devices. |
Mobile Device Security (iOS & Android)
Mobile devices are a frequent target due to their personal data and constant connectivity.
Operating System | Recommendation |
iOS and Android | Only download apps from the official App Store (iOS) or Google Play Store (Android). These stores have review processes to check for malicious content. |
iOS and Android | Review the permissions an app requests before installing it. An app should only request permissions relevant to its function (e.g., a photo editor needing access to your photos). |
iOS and Android | Keep your device locked with a strong PIN, password, or biometric (fingerprint/face ID) authentication. Biometrics are preferable. |
iOS and Android | Do not Root / Jailbreak your device. Doing so bypasses built-in security features and significantly exposes you to risk. |
Android Specific | Disable the "Install unknown apps" or "Allow installs from this source" setting unless absolutely necessary and only for trusted sources. |
Mac OS and Windows Security
Operating System | Recommendation |
Mac OS | Ensure your System Settings are configured to only allow apps downloaded from the App Store and identified developers. |
Windows | Use Windows Security (Defender) and ensure real-time protection is active. Regularly run scans. |
Windows and Mac OS | Be cautious of pop-ups or warnings claiming your device is infected. Close the browser window immediately, do not click on the warning, and run a full system scan with your antivirus software. |
Browser Security and Extensions
Your web browser is a primary entry point for online threats. Securing it is vital.
Securing Your Browser
Keep Your Browser Updated: Browsers like Chrome, Firefox, Edge, and Safari regularly release security updates. Ensure you are running the latest version.
Look for HTTPS: Always check that the website URL starts with https:// and look for a padlock icon in the address bar, indicating a secure connection. This is especially important for login and payment pages.
Disable Auto-Fill for Sensitive Data: Avoid storing passwords, credit card numbers, or personal addresses in your browser's auto-fill feature.
Be Wary of Advertisements: Malicious ads (malvertising) can be injected into legitimate websites and lead to malware downloads or phishing pages. Avoid clicking on suspicious or overly intrusive ads, even on trusted sites. Consider using a reputable ad-blocker or privacy-focused browser to mitigate this risk.
Be Wary of Fake Websites (Typosquatting/Spoofing): Always verify the website's URL. Scammers often create fake websites that look identical to legitimate ones (like your bank or a major retailer) but use a slightly altered URL (e.g., micros0ft.com instead of microsoft.com, or adding extra words like amazon-support.com).
To spot them and verify authenticity:
Check the URL Bar Closely: Look for misspellings, extra hyphens, or unusual characters in the domain name.
Verify the Domain: The primary domain name (the part right before the .com, .org, or other top-level domain) should be correct.
Use Search Engines: If you receive a link via email or text, do not click it. Instead, open a new browser tab and search for the company's official website yourself.
Look for Security Seals and Contact Info: Legitimate e-commerce or financial sites will usually display valid security seals (like VeriSign) and have easily accessible, working contact information and physical addresses. Fake sites often lack these or use non-functional placeholder information.
Malicious Browser Extensions
Browser extensions can significantly enhance functionality, but malicious extensions can capture your data, track your browsing, or inject ads.
Install Sparingly: Only install extensions you absolutely need.
Source and Reviews: Only install extensions from the official store (e.g., Chrome Web Store, Firefox Add-ons). Check the developer, read reviews, and look at the number of users. A legitimate extension will usually have a large user base and consistent positive reviews.
Check Permissions: Pay close attention to the permissions an extension requests. If a simple extension, like a note-taker, asks for permission to "read and change all your data on all websites," it may be overreaching.
Remove Unused Extensions: Regularly review and remove any extensions you no longer use.
Public Wi-Fi and VPNs
Connecting to public Wi-Fi networks in places like coffee shops, airports, and hotels poses significant security risks because the connection is often unsecured, making your data vulnerable to interception by others on the same network (eavesdropping or "man-in-the-middle" attacks).
Best Practices for Public Wi-Fi
Action | Description |
Always Use a VPN | A Virtual Private Network (VPN) encrypts your internet traffic, creating a secure tunnel between your device and the VPN server. You should always use a reputable VPN service when connected to any public or unsecured Wi-Fi network to protect your data from being intercepted. |
Confirm HTTPS | Even when using a VPN, always ensure that websites you visit, especially those requiring logins or payments, use HTTPS (indicated by https:// in the URL and the padlock icon). This adds an extra layer of encryption for data exchanged with that specific site. |
Avoid Sensitive Transactions | If possible, avoid conducting sensitive transactions, like banking or accessing confidential work accounts, while on public Wi-Fi, even with a VPN. Wait until you can connect to a trusted home or private cellular network. |
Disable Auto-Connect | Configure your devices to not automatically connect to public Wi-Fi networks. Manually review and select the network you intend to join. |
Strengthening Authentication with a Password Manager
Creating and managing unique, complex passwords for every single account is nearly impossible to do manually. A dedicated Password Manager is the essential tool for implementing strong authentication and is highly recommended.
Password Manager Recommendation
Recommendation | Details |
Use a Password Manager | A reputable password manager (e.g., Google/Apple Password Manager, 1Password, LastPass) is the safest way to generate, store, and use strong, unique passwords or passphrases for all your accounts. It eliminates the need to remember dozens of complex logins and securely syncs them across your devices. |
Generate Unique Passwords | Use your password manager's built-in functionality to generate long, complex, and unique passwords for every single online service. Never reuse passwords. |
Secure the Password Manager | The password manager's master password must be the strongest and most secure passphrase you use, and it must be protected with Multi-Factor Authentication (MFA). |
Physical Device Security
While much of digital security focuses on software and networks, the physical security of your devices is a critical component of data protection.
Action | Description |
Never Leave Unattended | Never leave your laptop, tablet, or smartphone unattended in public places (e.g., libraries, cafes, airports). A moment's distraction is all a thief needs. |
Use Screen Locks | Always keep your device's screen locked with a strong PIN, password, or biometrics (fingerprint/Face ID) when not actively in use. This protects your data if the device is lost or stolen, even in secure environments like an office or home. |
Be Aware of "Shoulder Surfing" | Be conscious of your surroundings when entering sensitive information (passwords, PINs) and shield your screen from others who may be trying to observe (shoulder surfing). |
Utilize Tracking Features | Ensure "Find My" (iOS/Mac) or "Find My Device" (Android/Windows) is enabled. As noted in the Device Protection section, these features allow you to remotely locate, lock, or wipe a device if it is lost or stolen. |
Reporting Fraud and Compromised Accounts
Taking immediate action to report fraud or a compromised account is crucial for limiting damage and assisting recovery efforts.
General Reporting Best Practice
Document Everything: Keep a detailed record of the incident, including when it occurred, what information was compromised, screenshots of phishing attempts, and dates/times of all phone calls and emails to banks and companies.
Use Official Channels: Always use the official, verified contact information (phone number or website) for any organization you need to contact. Never use contact information provided in a suspicious email or text message.
Steps for Reporting a Compromised Account
Action | Description |
1. Change Passwords Immediately | On the compromised account, and any other accounts using the same (or similar) password. Use a strong, unique passphrase or password manager. |
2. Enable Multi-Factor Authentication (MFA) | If not already enabled, turn on MFA immediately for the compromised account and all other critical accounts (email, banking, social media). |
3. Notify the Service Provider | Contact the company or service whose account was compromised (e.g., your bank, email provider, social media platform). Use the official support channels found on their website, not links from a suspicious email. |
4. Scan Your Device | Run a full scan using reputable anti-malware or endpoint protection software to check for any malware or keyloggers that may have been installed to steal your credentials. |
5. Review Account Activity | Check for unauthorized transactions, emails sent, or settings changes. Document everything you find, including dates and times. |
Steps for Reporting Financial Fraud
Action | Description |
1. Contact Your Financial Institution | Immediately call your bank or credit card company to report the fraudulent charges or activity. They can freeze the account, cancel the card, and initiate the dispute process. |
2. File a Police Report | If a significant amount of money was lost, or if you are a victim of identity theft, file a report with your local law enforcement. This report may be required by your bank or insurance company. |
3. Contact Credit Bureaus (for Identity Theft) | Place a fraud alert on your credit reports with the three major credit bureaus (Equifax, Experian, and TransUnion). This makes it harder for criminals to open new lines of credit in your name. |
4. Report to Government Agencies | Report the fraud to the relevant consumer protection agencies in your region. In the U.S., this includes the Federal Trade Commission (FTC) at IdentityTheft.gov or ReportFraud.ftc.gov. |
