In 2024, a forty-two-year-old man was arrested for creating an \u201cevil twin\u201d public wi-fi that mimicked the airport\u2019s legitimate network. People unwittingly connected to his malicious network and exposed their sensitive information. The \u201cevil twin\u201d scam is regularly used today by criminals and is one of the hidden dangers to using public wi-fi(<\/sup>1<\/sup>)<\/sup>.  Many victims need identity theft protection services in order to recover. However, there are a lot more dangers that you should be aware of.  <\/p>\n\n\n\n

Public wi-fi is extremely appealing in certain circumstances. It\u2019s free, accessible, and available in convenient locations like airports or hotels. However, connecting to public wi-fi has risks. A quarter of regular wi-fi users reported experiencing a security issue from using public wi-fi(<\/sup>2<\/sup>)<\/sup>. This unsafe wi-fi has open network security which easily allows wi-fi hacking from bad actors. To combat the ever-advancing strategies of cybercriminals, you need to arm yourself with the knowledge of their current tactics.  <\/p>\n\n\n\n

<\/span>How Hackers Exploit Unsafe Wi-Fi Networks <\/span><\/h2>\n\n\n\n

Cybercriminals have many options when it comes to exploiting public wi-fi. They can use wi-fi hacking to exploit the vulnerabilities on a device or network. They can also use phishing scams<\/a> to trick users into sharing sensitive information over a network. Here are some more ways hackers use unsafe wi-fi. <\/p>\n\n\n\n

<\/span>Man-in-the-Middle (MITM) Attacks <\/span><\/h3>\n\n\n\n

The man-in-the middle attack is a wi-fi hacking technique in which a hacker uses an unsafe wi-fi network to eavesdrop on the communications sent between the victim\u2019s device and the hotspot. The most common targets for sensitive data are login credentials, emails, or payment data. <\/p>\n\n\n\n

<\/span>Fake Hotspots and Evil Twin Networks <\/span><\/h3>\n\n\n\n

The \u201cevil twin\u201d hotspot is when a malicious actor sets up a public wi-fi with open network security and disguises it as a trusted source. Victims connect to the unsafe wi-fi network and unwittingly send the perpetrator their sensitive data or login credentials. Scammers will disguise the names of their malicious networks as trusted public wi-fi networks like \u201cFree Airport Wi-Fi\u201d or \u201cFree Holiday Inn Wi-Fi.\u201d Hackers also use phishing scams to direct victims to a login page where they are prompted to enter their credentials for social networks or email.  <\/p>\n\n\n\n

<\/span>Malware Distribution Over Open Network Security <\/span><\/h3>\n\n\n\n

Whether it is open network security or encrypted, one of the ways malware<\/a> can be distributed is through the network connection. Two devices on the same network increases the risk of malware distribution since these devices are discoverable to each other. <\/p>\n\n\n\n

Public wi-fi has risks with malware as well. Cybercriminals use network hacking to spread malware across different devices. Hackers can also use phishing scams in the form of pop-ups and downloads to plant malware on specific devices on the network. <\/p>\n\n\n\n

<\/span>What Data Is at Risk on Public Wi-Fi? <\/span><\/h2>\n\n\n\n

Cybercriminals using public wi-fi to hack into devices or steal information is an older technique that took advantage of unsecure websites and wireless networks. Now with the wide adoption of websites using HTTPS for encryption, most information is protected. However, there are still public network risks and data that can be exposed in certain scenarios. <\/p>\n\n\n\n
