Airports, caf\u00e9s, hotels, even libraries can harbor dangerous Vampire Wi-Fi networks.<\/p>\n<p>These vampires pass themselves off as legitimate public Wi-Fi hotspots, using names that look innocent enough, such as \u201cFREE_WIFI\u201d and \u201cAT&amp;T_FREE_WIFI\u201d.\u00a0 These can potentially be \u201cevil twin networks,\u201d they often mimic the name of the airport you\u2019re in, or the place where you\u2019re grabbing a quick coffee and some laptop time while you\u2019re on the road. In fact, <strong>when you connect to a vampire or evil twin network, you\u2019re connecting to a hacker.<\/strong><\/p>\n<p>These networks are relatively easy to set up. With just a few hundred dollars of gear, attackers can set up these digital bloodsuckers anywhere. The moment you log on, they begin<strong> feeding on your data, <\/strong>using tools called packet sniffers to capture and analyze every bit you send.<\/p>\n<p>So say you\u2019re on the road and log into one of these networks, a hacker on the network can see what you\u2019re connecting to and what data you\u2019re passing along. Your credit card number while you shop. Your password when you bank. That confidential contract you just sent to a client. And your email password when your app regularly checks for mail every few minutes or so.<\/p>\n<p>What tools let hackers snoop? Network analyzers, or packet sniffers as many call them. A bad actor can gather up data with a packet sniffer, analyze it, and pluck out the sensitive bits of info that are of value. Before you know it, you\u2019re a victim of identity theft.<\/p>\n<p><strong>Another common vampire Wi-Fi ploy is to set up a phony login screen<\/strong> that asks for a username and password, often for popular online services like Google and Apple. In this case, the hacker gets the keys to all the personal info, apps, files, and financial info connected to them.<\/p>\n<h2><strong>How to spot phony evil twin public Wi-Fi networks<\/strong><\/h2>\n<p>Hackers typically take lengths to make these networks look legitimate, but they may give off signs:<\/p>\n<ul>\n<li>The Wi-Fi network has no\u00a0password.<\/li>\n<li>The Wi-Fi network is not set up with\u00a0Wi-Fi protected access (WPA)\u00a0on the router.<\/li>\n<li>The Wi-Fi network is open to Secure Sockets Layer (SSL) attacks. (An SSL is a digital certificate\u00a0that authenticates a website&#8217;s identity and allows for secure, encrypted connections to banking, shopping, and financial sites, to name a few.)<\/li>\n<\/ul>\n<p>Still, even with some of these flags, they can be tough to spot. And that\u2019s a reason why <a href=\"https:\/\/www.mcafee.com\/en-us\/antivirus\/mobile.html?path=blogs\">our mobile security apps for iOS and Android<\/a> analyze Wi-Fi networks before you connect to them\u2014letting you know if a connection is Safe, Risky, or altogether Unsafe.<\/p>\n<h2><strong>How to stay safe from evil twin networks when using public Wi-Fi<\/strong><\/h2>\n<p>Your best bet when using any public Wi-Fi at all is to use a VPN.<\/p>\n<p>A\u202fVPN\u202fis an\u202fapp that you install on\u202fyour\u202fdevice\u202fto help keep your data safe as you browse\u202fthe internet. With your VPN on, your device\u202fmakes a secure\u202fconnection\u202fto\u202fa VPN server that routes internet traffic through an encrypted \u201ctunnel.\u201d This keeps your online activity private on any network, shielding it from prying eyes.<\/p>\n<p><strong>While you\u2019re on a VPN, you can browse and bank with the confidence that your passwords, credentials, and financial info are secure.<\/strong> If a hacker attempts to intercept your web traffic, they\u2019ll only see garbled content, thanks to your VPN\u2019s encryption functionality.<\/p>\n<p>With that, choosing a secure and trustworthy VPN provider is a must. <a href=\"https:\/\/www.mcafee.com\/learn\/vpn?path=blogs\">A VPN like ours has both your security and privacy in mind<\/a>. In a VPN, look for:<\/p>\n<ul>\n<li>The same encryption strength that banks use.<\/li>\n<li>One that doesn\u2019t log or track what you do online, so your online activity remains private. \u200b<\/li>\n<li>A VPN that\u2019s independently audited for security and privacy.<\/li>\n<li>One that covers plenty of devices and that offers unlimited data.<\/li>\n<li>Automatically connects when you connect to public Wi-Fi.<\/li>\n<\/ul>\n<p>Not every VPN offers these features. Selecting one that does gives you the protection you want paired with the privacy you want. You\u2019ll find them all in our VPN, which is <a href=\"https:\/\/www.mcafee.com\/en-us\/identity-theft\/protection.html?path=blogs\">also included as part of our McAfee+ plans<\/a>.<\/p>\n<h2><strong>More ways you can stay safe on public Wi-Fi<\/strong><\/h2>\n<p>Several other straightforward steps can keep you safer from vampire and evil twin Wi-Fi\u2014and safer while using public Wi-Fi in general:<\/p>\n<ul>\n<li><strong>Double-check the network name:<\/strong>\u00a0If you\u2019re at a caf\u00e9, hotel, or airport, check with an employee for the exact name of their official Wi-Fi network before connecting. Don\u2019t automatically trust a network just because its name looks right or has a particularly strong signal. (In fact, some hackers boost their phony Wi-Fi signals to make them look more attractive.)<\/li>\n<li><strong>Disable auto-join:<\/strong>\u00a0Turn off the auto-join feature for Wi-Fi on your devices. This prevents your phone or laptop from connecting to malicious networks automatically.<\/li>\n<li><strong>See if it can wait:<\/strong>\u00a0If you can wait to bank, shop, check email, or do anything that involves passwords or sensitive info, do it on a secure connection at home. If it absolutely can\u2019t wait, use your VPN or cellular connection.<\/li>\n<li><strong>Use your own hotspot:<\/strong>\u00a0Another secure option is to use a personal hotspot from your phone&#8217;s cellular data. This gives you a private connection that is much harder for attackers to exploit.\u00a0That might leave you with a slower connection and possibly eat into your data plan, but those are small concerns compared to the major headache of identity theft.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Vampire Wi-Fi networks aren&#8217;t going anywhere. Hackers will keep setting up these traps because they work. People see &#8220;free Wi-Fi&#8221; and click without thinking twice. But now you know better. You&#8217;ve got the tools to spot the red flags, the habits to stay protected, and most importantly, you understand why a quality VPN isn&#8217;t optional anymore\u2014it&#8217;s essential.<\/p>\n<p><strong><a href=\"https:\/\/www.mcafee.com\/en-us\/identity-theft\/protection.html\">McAfee+ gives you everything we&#8217;ve talked about<\/a>: bank-level encryption, zero-logging policies, independent security audits, and that smart auto-connect feature that kicks in when you need it most.<\/strong> Plus, unlimited data across all your devices, because who has time to ration their security?<\/p>\n<p>Your personal information is worth protecting. Your financial data, your work files, your private conversations, they&#8217;re all valuable to the wrong people.
