The cybersecurity threat landscape in 2025 is more diverse than ever. Ransomware attacks have evolved into &#8220;double extortion&#8221; schemes where criminals not only encrypt your data but threaten to leak it publicly. Phishing emails have become nearly indistinguishable from legitimate communications thanks to generative AI tools that can mimic writing styles perfectly.<\/p>\n<p>According to recent statistics from cybersecurity firms, there is a hacker attack every 39 seconds on average, affecting one in three Americans every year. Small businesses are particularly vulnerable \u2014 43% of cyberattacks target small businesses, yet only 14% are prepared to defend themselves. The average cost of a data breach now exceeds $4 million globally, with healthcare and finance being the most targeted sectors.<\/p>\n<p>Beyond financial loss, cyberattacks can lead to identity theft, reputational damage, emotional distress, and long-term privacy violations. The good news? The vast majority of these attacks can be prevented by following basic cybersecurity hygiene practices. Let&#8217;s explore them in depth.<\/p>\n<h2 id=\"passwords\">Password Hygiene: Your First Line of Defense<\/h2>\n<p>Despite years of warnings, weak passwords remain the number one cause of account compromise. The most common passwords in 2024 were still &#8220;123456,&#8221; &#8220;password,&#8221; and &#8220;qwerty.&#8221; If any of your passwords resemble these, change them immediately.<\/p>\n<p><strong>What makes a strong password?<\/strong> A strong password should be at least 12-16 characters long, include a mix of uppercase letters, lowercase letters, numbers, and special characters, and \u2014 most importantly \u2014 be unique for every account you own. Reusing passwords across multiple sites is one of the riskiest behaviors online. When one site suffers a data breach (and they will), attackers try those same credentials on email, banking, social media, and other high-value platforms.<\/p>\n<p><strong>Enter the password manager.<\/strong> Password managers like Bitwarden, 1Password, and KeePass generate and store complex, unique passwords for every account. You only need to remember one master password \u2014 make it a long passphrase (e.g., &#8220;Correct-Horse-Battery-Staple-Dragon&#8221;) rather than a complex jumble of characters. Passphrases are easier to remember yet significantly harder to crack.<\/p>\n<p><strong>Pro tip:<\/strong> Enable biometric authentication (fingerprint or facial recognition) where available. Combine it with a strong master password for your password manager. Never store passwords in your browser&#8217;s built-in password manager without a master password layer.<\/p>\n<p>Do not rely on security questions as a backup method. Information like your mother&#8217;s maiden name, your pet&#8217;s name, or your high school can often be found on social media. When a site requires security questions, treat the answers as additional passwords \u2014 use randomly generated answers stored in your password manager.<\/p>\n<h2 id=\"2fa\">Two-Factor Authentication (2FA) \u2014 The Non-Negotiable<\/h2>\n<p>Two-factor authentication adds a second layer of security beyond your password. Even if a hacker steals your password, they won&#8217;t be able to access your account without the second factor. This single step blocks approximately 99.9% of automated cyberattacks, according to Microsoft.<\/p>\n<p>There are several types of 2FA, ranked from least to most secure:<\/p>\n<ol>\n<li><strong>SMS-based 2FA<\/strong> \u2014 A code sent via text message. Better than nothing, but vulnerable to SIM-swapping attacks where hackers trick your mobile carrier into transferring your number to their SIM card.<\/li>\n<li><strong>Authenticator apps<\/strong> \u2014 Google Authenticator, Microsoft Authenticator, Authy, and others generate time-based one-time passwords (TOTP) that refresh every 30 seconds. These are significantly more secure than SMS.<\/li>\n<li><strong>Hardware security keys<\/strong> \u2014 Physical devices like YubiKey or Google Titan that plug into your USB port or connect via NFC. These are the gold standard of 2FA and are virtually immune to phishing attacks.<\/li>\n<li><strong>Passkeys<\/strong> \u2014 A new standard backed by Apple, Google, and Microsoft that replaces passwords entirely with cryptographic key pairs stored on your device. Passkeys are resistant to phishing, have no passwords to leak, and sync across your devices via your cloud account.<\/li>\n<\/ol>\n<p><strong>Recommendation:<\/strong> Enable 2FA on every account that supports it, especially on email, banking, social media, and password managers. If available, choose hardware security keys or passkeys first, authenticator apps second, and SMS only as a last resort. Remember to save backup codes in a secure offline location in case you lose access to your 2FA device.<\/p>\n<h2 id=\"phishing\">Phishing Awareness: Don&#8217;t Take the Bait<\/h2>\n<p>Phishing is the most common entry point for cyberattacks, accounting for over 90% of data breaches. Phishing attacks come in many forms: emails pretending to be from your bank, fake login pages that look identical to real ones, text messages claiming your package couldn&#8217;t be delivered, and even phone calls (vishing) where scammers impersonate tech support or government officials.<\/p>\n<p>With the rise of AI-generated content, phishing emails have become more convincing than ever. Grammar errors \u2014 once a telltale sign of phishing \u2014 are now rare in well-crafted attacks. Deepfake audio and video are also being used in sophisticated scams (known as &#8220;deepfake social engineering&#8221;).<\/p>\n<p><strong>How to spot a phishing attempt:<\/strong><\/p>\n<ul>\n<li><strong>Check the sender&#8217;s email address carefully.<\/strong> A legitimate email from PayPal comes from @paypal.com, not @paypa1-support.com or @paypal-security-alerts.net.<\/li>\n<li><strong>Hover over links before clicking.<\/strong> Most email clients show the destination URL when you hover. If the displayed URL looks suspicious, don&#8217;t click.<\/li>\n<li><strong>Beware of urgency and fear tactics.<\/strong> &#8220;Your account will be suspended in 24 hours&#8221; or &#8220;Unauthorized login detected \u2014 verify immediately&#8221; are common psychological triggers.<\/li>\n<li><strong>Never download attachments you weren&#8217;t expecting.<\/strong> Even if the sender appears legitimate, verify with them through a separate communication channel.<\/li>\n<li><strong>If it sounds too good to be true, it probably is.<\/strong> Lottery winnings, inheritance claims, and unsolicited job offers are almost always scams.<\/li>\n<\/ul>\n<p><strong>Safe practice:<\/strong> When in doubt, navigate to the website directly by typing the URL into your browser rather than clicking links in emails. If your bank sends you a security alert, open your banking app or call the number on the back of your card instead of using the contact details in the email.<\/p>\n<h2 id=\"software\">Keep Your Software Updated \u2014 Yes, Every Single Update<\/h2>\n<p>Software updates are not just about new features or interface changes. They almost always include patches for security vulnerabilities that have been discovered since the last release. Cybercriminals actively scan for systems running outdated software and exploit known vulnerabilities within hours or days of a patch being released.<\/p>\n<p>The WannaCry ransomware attack in 2017, which affected over 200,000 computers across 150 countries and caused billions of dollars in damage, exploited a vulnerability that Microsoft had already patched two months earlier. Victims simply hadn&#8217;t installed the update.<\/p>\n<p><strong>What to keep updated:<\/strong><\/p>\n<ul>\n<li>Operating systems (Windows, macOS, Linux, iOS, Android)<\/li>\n<li>Web browsers (Chrome, Firefox, Safari, Edge)<\/li>\n<li>Browser extensions and plugins<\/li>\n<li>Antivirus and security software<\/li>\n<li>Firmware on routers, smart home devices, and IoT gadgets<\/li>\n<li>Applications you use regularly (Office, Zoom, Slack, Adobe, etc.)<\/li>\n<\/ul>\n<p><strong>Enable automatic updates<\/strong> wherever possible. For operating systems, turn on &#8220;auto-update&#8221; so critical security patches install without requiring manual action. However, be cautious with major version updates on production or work machines \u2014 it&#8217;s wise to wait a few days to ensure compatibility issues are resolved.<\/p>\n<p>Set aside time each month to check for firmware updates on your router and other network devices. Many people never update their router firmware, leaving their entire home network exposed to known exploits.<\/p>\n<h2 id=\"antivirus\">Antivirus and Endpoint Protection<\/h2>\n<p>While Windows Defender (now called Microsoft Defender Antivirus) has improved significantly and is sufficient for most users, dedicated security suites offer additional layers of protection. macOS users are not immune either \u2014 while fewer malware strains target macOS, their numbers have been increasing steadily.<\/p>\n<p><strong>Top security tools for 2025:<\/strong><\/p>\n<ul>\n<li><strong>Bitdefender<\/strong> \u2014 Consistently tops independent lab tests with excellent malware detection rates and low system impact.<\/li>\n<li><strong>Kaspersky<\/strong> \u2014 Strong protection with a comprehensive feature set (note: users concerned about privacy may want to research the company&#8217;s jurisdiction).<\/li>\n<li><strong>Malwarebytes<\/strong> \u2014 Excellent as a secondary scanner for on-demand malware removal.<\/li>\n<li><strong>ESET<\/strong> \u2014 Lightweight and highly customizable, ideal for advanced users.<\/li>\n<li><strong>Sophos Home<\/strong> \u2014 Good remote management features for families.<\/li>\n<\/ul>\n<p><strong>Important:<\/strong> Having multiple antivirus programs running simultaneously can cause conflicts and actually reduce protection. Choose one comprehensive solution and stick with it. Additionally, enable &#8220;real-time protection&#8221; \u2014 some users disable it to improve system performance, but this defeats the purpose of having antivirus software.<\/p>\n<p>Beyond traditional antivirus, consider using Endpoint Detection and Response (EDR) tools if you run a small business. EDR solutions detect behavior-based threats that traditional signature-based antivirus may miss.<\/p>\n<h2 id=\"network\">Home Network and Wi-Fi Security<\/h2>\n<p>Your home router is the gateway to all your connected devices. If it&#8217;s compromised, every device on your network is at risk. Here&#8217;s how to secure it:<\/p>\n<ul>\n<li><strong>Change the default admin credentials.<\/strong> Most routers ship with &#8220;admin\/admin&#8221; or &#8220;admin\/password&#8221; as login credentials. Change both the username and password immediately.<\/li>\n<li><strong>Use WPA3 encryption<\/strong> for your Wi-Fi network. If your router doesn&#8217;t support WPA3, use WPA2-AES (not WPA2-TKIP or the outdated WEP).<\/li>\n<li><strong>Disable WPS (Wi-Fi Protected Setup).<\/strong> WPS has known vulnerabilities that can be exploited to bypass your Wi-Fi password within hours.<\/li>\n<li><strong>Create a guest network<\/strong> for visitors and IoT devices. This isolates potentially vulnerable smart home gadgets from your main computers and phones.<\/li>\n<li><strong>Disable remote administration<\/strong> unless you absolutely need it and have configured strong security measures.<\/li>\n<li><strong>Update router firmware regularly.<\/strong> Check your router manufacturer&#8217;s website or app for firmware updates at least quarterly.<\/li>\n<li><strong>Consider using a separate DNS service<\/strong> like Cloudflare (1.1.1.1) or Quad9 (9.9.9.9) that includes built-in malware and phishing protection.<\/li>\n<\/ul>\n<p>If you have a large home or need mesh Wi-Fi, ensure your mesh system supports modern security standards. Systems from Eero, Google Nest, and TP-Link Deco generally receive regular security updates.<\/p>\n<h2 id=\"backup\">The 3-2-1 Backup Strategy<\/h2>\n<p>Ransomware attacks encrypt your files and demand payment for the decryption key. Even if you follow every other cybersecurity practice, a zero-day exploit or sophisticated targeted attack could still get through. That&#8217;s where backups save you.<\/p>\n<p>The 3-2-1 backup rule is the gold standard:<\/p>\n<ul>\n<li><strong>3<\/strong> \u2014 Keep three copies of your data (one primary + two backups)<\/li>\n<li><strong>2<\/strong> \u2014 Store them on two different types of media (e.g., external hard drive + cloud storage)<\/li>\n<li><strong>1<\/strong> \u2014 Keep one copy offsite (cloud storage or a safe deposit box at another location)<\/li>\n<\/ul>\n<p><strong>Best backup solutions for 2025:<\/strong><\/p>\n<ul>\n<li><strong>Cloud backup:<\/strong> Backblaze ($7\/month unlimited), IDrive, or CrashPlan for continuous automated backups.<\/li>\n<li><strong>Local backup:<\/strong> Use tools like Veeam Agent (free for Windows), Time Machine (macOS), or rsync (Linux) to back up to an external drive.<\/li>\n<li><strong>Hybrid:<\/strong> Combine a local NAS (Synology, QNAP) with cloud backup for comprehensive protection.<\/li>\n<li><strong>Follow the &#8220;air gap&#8221; principle:<\/strong> After backing up, disconnect the external drive. A drive that&#8217;s always connected is vulnerable to ransomware encryption.<\/li>\n<\/ul>\n<p>Test your backups regularly. A backup you&#8217;ve never tried to restore is not a backup \u2014 it&#8217;s a wish. Set a recurring calendar reminder to perform a test restore of critical files every quarter.<\/p>\n<h2 id=\"browsing\">Safe Browsing and Browser Hardening<\/h2>\n<p>Your web browser is your primary interface to the internet. Hardening it is one of the most effective ways to protect yourself online:<\/p>\n<ul>\n<li><strong>Use a privacy-focused browser.<\/strong> Firefox with privacy settings, Brave, or even Ungoogled Chromium offer better privacy than stock Chrome.<\/li>\n<li><strong>Install ad-blockers.<\/strong> uBlock Origin blocks not only ads but also malicious scripts and trackers. It&#8217;s one of the most effective security tools available \u2014 and it&#8217;s free.<\/li>\n<li><strong>Use DNS-based filtering.<\/strong> Enable DNS-over-HTTPS (DoH) in your browser settings. This prevents your ISP from seeing which websites you visit.<\/li>\n<li><strong>Disable or limit third-party cookies.<\/strong> Modern browsers offer to block third-party cookies entirely or partition them by site.<\/li>\n<li><strong>Be selective with browser extensions.<\/strong> Extensions have access to everything you do in your browser. Only install extensions from reputable developers, and audit your extensions periodically.<\/li>\n<li><strong>Enable &#8220;HTTPS-Only Mode&#8221;<\/strong> or use the HTTPS Everywhere extension to force encrypted connections wherever possible.<\/li>\n<li><strong>Clear cookies and cache regularly<\/strong> or configure your browser to auto-delete them on exit.<\/li>\n<\/ul>\n<p><strong>Watch out for:<\/strong> Fake browser extension scams. Cybercriminals create malicious extensions that appear legitimate (e.g., fake ad blockers or coupon finders) but steal your data. Stick to well-known extensions with thousands of reviews.<\/p>\n<h2 id=\"socialmedia\">Social Media Privacy and Oversharing Risks<\/h2>\n<p>Social media platforms are treasure troves of personal information for cybercriminals and social engineers. Every post, photo, and check-in provides clues that can be used to guess passwords, answer security questions, or craft targeted phishing attacks.<\/p>\n<p><strong>Privacy best practices for social media:<\/strong><\/p>\n<ul>\n<li><strong>Set profiles to private.<\/strong> Review your privacy settings on Facebook, Instagram, LinkedIn, and X (formerly Twitter) to limit who can see your posts and personal information.<\/li>\n<li><strong>Don&#8217;t share your location in real-time.<\/strong> Post vacation photos after you return home, not while you&#8217;re away. Similarly, avoid posting photos of your home exterior, mail, keys, or ID cards.<\/li>\n<li><strong>Be careful with quizzes and surveys.<\/strong> &#8220;What&#8217;s your Star Wars name?&#8221; and &#8220;What was your first car?&#8221; are often data collection schemes for common security questions.<\/li>\n<li><strong>Review third-party app access.<\/strong> Go through your connected apps on each platform and revoke access for apps you no longer use.<\/li>\n<li><strong>Disable facial recognition tagging<\/strong> where possible, and turn off location tagging for individual posts.<\/li>\n<li><strong>Use a separate email address<\/strong> for social media accounts to avoid linking them to your primary inbox.<\/li>\n<\/ul>\n<p>Think before you share. A seemingly innocent post about &#8220;My dog Max, born in 2019&#8221; gives away your pet&#8217;s name (a common security question) and when you got them. Cybercriminals piece together these fragments to build comprehensive profiles of their targets.<\/p>\n<h2 id=\"publicwifi\">Public Wi-Fi Dangers and VPN Usage<\/h2>\n<p>Public Wi-Fi networks in coffee shops, airports, hotels, and libraries are notoriously insecure. Attackers can set up fake access points with the same name as legitimate networks (the &#8220;Evil Twin&#8221; attack) or eavesdrop on traffic passing through the router.<\/p>\n<p><strong>How to stay safe on public Wi-Fi:<\/strong><\/p>\n<ul>\n<li><strong>Always use a VPN<\/strong> when connected to public Wi-Fi. A VPN encrypts all your internet traffic, making it unreadable to anyone monitoring the network.<\/li>\n<li><strong>Look for the padlock icon<\/strong> in your browser&#8217;s address bar \u2014 it indicates the site uses HTTPS encryption. Never enter sensitive information on an HTTP page.<\/li>\n<li><strong>Turn off file sharing and network discovery<\/strong> when connecting to public networks. On Windows, set the network profile to &#8220;Public&#8221; \u2014 this disables many sharing features.<\/li>\n<li><strong>Disable auto-connect<\/strong> to open Wi-Fi networks to prevent your device from automatically joining malicious networks.<\/li>\n<li><strong>Use your mobile hotspot<\/strong> instead of public Wi-Fi when possible. Cellular data connections are generally more secure than open Wi-Fi.<\/li>\n<\/ul>\n<p><strong>Choosing a VPN:<\/strong> Not all VPNs are equal. Some free VPNs actually sell your data or inject ads. Look for a VPN with a verified no-logs policy, strong encryption (AES-256), a kill switch feature, and independent security audits. Recommended providers include Mullvad, ProtonVPN (free tier available), IVPN, and Windscribe. Avoid VPNs owned by companies with track records of privacy violations.<\/p>\n<h2 id=\"mobile\">Mobile Device Security<\/h2>\n<p>Smartphones have become extensions of ourselves, containing our photos, messages, banking apps, and even cryptocurrency wallets. Mobile security is just as important as desktop security \u2014 if not more so, given that we carry our phones everywhere.<\/p>\n<p><strong>Mobile security checklist:<\/strong><\/p>\n<ul>\n<li><strong>Keep your phone locked.<\/strong> Use a strong PIN (6+ digits), biometric authentication, or both. Avoid pattern locks that leave fingerprint smudges revealing the pattern.<\/li>\n<li><strong>Only install apps from official stores.<\/strong> Google Play Store and Apple App Store have security screening processes. Sideloading apps (installing from outside the store) dramatically increases malware risk \u2014 especially on Android.<\/li>\n<li><strong>Review app permissions regularly.<\/strong> Does a flashlight app really need access to your contacts and location? Revoke unnecessary permissions in your phone&#8217;s settings.<\/li>\n<li><strong>Disable Bluetooth when not in use.<\/strong> BlueBorne and other Bluetooth-based attacks can compromise devices with Bluetooth left on.<\/li>\n<li><strong>Turn off &#8220;Install from Unknown Sources&#8221;<\/strong> on Android if it was enabled. This setting allows the installation of apps outside the Play Store.<\/li>\n<li><strong>Enable remote wipe and find-my-device features.<\/strong> Both iOS (Find My) and Android (Find My Device) allow you to locate, lock, and erase your phone remotely if it&#8217;s lost or stolen.<\/li>\n<li><strong>Be cautious with public charging stations.<\/strong> &#8220;Juice Jacking&#8221; attacks use USB charging ports to transfer malware or steal data. Use your own charger wall plug and cable, or carry a USB data blocker.<\/li>\n<\/ul>\n<p><strong>Android-specific:<\/strong> Google Play Protect scans apps for malware, but it&#8217;s not foolproof. Consider using a mobile security app like Malwarebytes or Bitdefender Mobile Security for additional protection \u2014 especially if you install apps from outside the Play Store.<\/p>\n<h2 id=\"encryption\">Data Encryption: Protecting Data at Rest and in Transit<\/h2>\n<p>Encryption scrambles data so that only authorized parties can read it. Even if an attacker gains access to your encrypted files or intercepts your internet traffic, they won&#8217;t be able to make sense of the data without the decryption key.<\/p>\n<p><strong>Full-disk encryption:<\/strong> Enable full-disk encryption on all your devices. Windows users can use BitLocker (available on Pro\/Enterprise editions), macOS users have FileVault built in, and Linux users can use LUKS. Android and iOS encrypt device storage by default in modern versions.<\/p>\n<p><strong>File encryption:<\/strong> For sensitive files you want to share or email, use tools like VeraCrypt (open-source, cross-platform) or the built-in encryption features in productivity suites like Microsoft Office (encrypt with password).<\/p>\n<p><strong>Email encryption:<\/strong> Most email providers offer TLS encryption in transit (which protects against interception but not against the provider reading your emails). For truly private communication, use end-to-end encrypted services like ProtonMail, Tutanota, or PGP-encrypted emails.<\/p>\n<p><strong>Messaging apps:<\/strong> Use messaging apps with end-to-end encryption (E2EE) by default: Signal (gold standard \u2014 open-source and privacy-focused), WhatsApp (E2EE but owned by Meta), or iMessage (E2EE but only between Apple devices). Telegram&#8217;s &#8220;Secret Chats&#8221; are E2EE, but regular chats are not \u2014 use the Secret Chat mode for sensitive conversations.<\/p>\n<h2 id=\"iot\">Securing IoT and Smart Home Devices<\/h2>\n<p>The Internet of Things (IoT) has brought convenience to our homes \u2014 smart speakers, thermostats, doorbells, cameras, and light bulbs. However, many IoT devices have poor security: default passwords that can&#8217;t be changed, no automatic updates, and invasive data collection practices.<\/p>\n<p><strong>Smart home security tips:<\/strong><\/p>\n<ul>\n<li><strong>Put IoT devices on a separate VLAN or guest network.<\/strong> If a smart bulb or camera is compromised, the attacker won&#8217;t be able to access your main computers or phones.<\/li>\n<li><strong>Change default passwords immediately.<\/strong> Many IoT devices ship with &#8220;admin\/1234&#8221; or similar credentials that are publicly documented.<\/li>\n<li><strong>Disable unnecessary features.<\/strong> If your smart TV has a microphone and camera but you never use voice commands or video calls, disable those features in the settings.<\/li>\n<li><strong>Check for firmware updates<\/strong> every few months. Many IoT manufacturers release security patches that you need to install manually.<\/li>\n<li><strong>Research before you buy.<\/strong> Avoid IoT devices from companies with poor security track records. Look for devices that offer automatic updates, have been independently security-audited, and allow you to opt out of data collection.<\/li>\n<li><strong>Cover webcams<\/strong> when not in use with a physical slider or sticker. Many cybersecurity professionals do this as a simple visual deterrent.<\/li>\n<li><strong>Disable Universal Plug and Play (UPnP)<\/strong> on your router. UPnP allows devices to open ports automatically, which IoT malware often uses to spread.<\/li>\n<\/ul>\n<p>Smart speakers like Amazon Echo and Google Nest are always listening for their wake word. While the companies claim they only process audio after the wake word, privacy-conscious users may want to review their privacy settings and delete voice recordings regularly.<\/p>\n<h2 id=\"breach\">What to Do If You&#8217;ve Been Hacked<\/h2>\n<p>Despite your best efforts, no defense is 100% guaranteed. If you suspect your account or device has been compromised, act quickly:<\/p>\n<ol>\n<li><strong>Change your password immediately<\/strong> \u2014 using a different, uncompromised device if possible. Enable 2FA if it wasn&#8217;t active.<\/li>\n<li><strong>Log out all active sessions<\/strong> \u2014 Most services have a &#8220;sign out of all devices&#8221; option in security settings.<\/li>\n<li><strong>Check for unauthorized changes<\/strong> \u2014 Look for forwarding rules on your email, changed recovery information, or new linked payment methods.<\/li>\n<li><strong>Alert your bank<\/strong> if financial information may be compromised. Freeze your credit if identity theft is suspected.<\/li>\n<li><strong>Run a full antivirus scan<\/strong> on all devices you&#8217;ve used to access the compromised account.<\/li>\n<li><strong>Monitor your accounts<\/strong> for suspicious activity for several weeks after the incident.<\/li>\n<li><strong>Use HaveIBeenPwned.com<\/strong> to check if your email or passwords appear in known data breaches.<\/li>\n<li><strong>Report the incident<\/strong> to relevant authorities: the FBI&#8217;s IC3 (ic3.gov) for US residents, Action Fraud for UK residents, or your local cybersecurity agency.<\/li>\n<li><strong>Notify your contacts<\/strong> if your messaging accounts were compromised \u2014 attackers often use compromised accounts to spread spam or malware to the victim&#8217;s contacts.<\/li>\n<li><strong>Consider identity theft protection services<\/strong> if sensitive data like your Social Security number or passport details were exposed.<\/li>\n<\/ol>\n<p><strong>Proactive measure:<\/strong> Freeze your credit with all three major credit bureaus (Equifax, Experian, TransUnion). This prevents criminals from opening new accounts in your name, even if they have your personal information.
