You might think, “I use public wi-fi all the time, and I’ve never had a problem!” Sure, not that you know of, at least. The worrisome truth is—in tandem with the growing remote-worker population—cyberattacks are also on the rise and anyone using public wi-fi is at risk. In a Global Risk Report published in 2020, cyberattacks were named the fifth top-rated risk for companies across public and private sectors, and those attacks are expected to climb in ranking soon. The FBI reported 791,790 complaints of suspected internet crime in 2020—which is 300,000 more than reported in 2019—and estimated the financial toll at more than $4.2 billion. Protecting yourself from the risks of public wi-fi has never been more imperative. This is essential for businesses and individuals in virtually every industry, although some are much more vulnerable than others.
The widespread availability of public Wi-Fi has revolutionized the way we connect to the internet, making it easier than ever to stay online no matter where we are. However, as convenient as public Wi-Fi can be, it also poses significant risks to users' privacy and security. In this article, we will explore the risks and shortcomings of using public Wi-Fi and how unsecured networks can leave users vulnerable to cybercrime.
Risks of using public Wi-Fi:
Public Wi-Fi networks are generally unsecured, which means that anyone who is connected to the same network can potentially intercept and read the data being transmitted between devices. This opens the door to a variety of cybercrimes, such as interception attacks, man-in-the-middle attacks, snooping, and malware infection.
*Interception attacks* occur when a cybercriminal intercepts the communication between two devices and alters it to their advantage. For example, they could intercept a login credential, such as a password, and use it to gain access to sensitive information.
*Man-in-the-middle attacks* are similar to interception attacks, but involve the attacker inserting themselves into the middle of the communication between two devices. The attacker can then eavesdrop on the communication or modify it to their advantage.
*Snooping of data* occurs when a cybercriminal monitors the network traffic to obtain sensitive information such as login credentials or financial data. They can then use this information for their own malicious purposes, such as identity theft or financial fraud.
*Malware infection* is another risk of using public Wi-Fi. Cybercriminals can use unsecured public Wi-Fi networks to distribute malware, such as viruses or ransomware, to unsuspecting users. Once the malware infects a device, it can steal data, encrypt files, or hijack the device.
_Shortcomings of using public Wi-Fi:_
The security measures implemented by public Wi-Fi providers are often inadequate to protect users from cyber threats. This is due to the limitations of securing a public network, such as the large number of users, diverse devices, and lack of control over user behavior.
Public Wi-Fi providers often rely on simple encryption protocols, such as WEP or WPA, which are no longer considered secure. In addition, many public Wi-Fi networks do not require users to enter a password or any other form of authentication, making it easy for cybercriminals to gain access to the network.
Another shortcoming of using public Wi-Fi is the lack of control over user behavior. Users may unwittingly compromise their own security by connecting to a fake network, downloading malicious software, or clicking on phishing links.
_Best practices for using public Wi-Fi safely:_
There are several best practices that users can adopt to reduce the risks of using public Wi-Fi:
Use a virtual private network (VPN): A VPN encrypts all internet traffic between a device and a server, making it difficult for cybercriminals to intercept or read the data.
Avoid sensitive activities: Users should avoid logging into sensitive accounts, such as banking or email, while using public Wi-Fi. If they must do so, they should use two-factor authentication and check for the padlock symbol in the browser address bar.
Keep software up-to-date: Users should keep their devices and software up-to-date to ensure they are protected against known vulnerabilities.
Disable auto-connect: Users should disable auto-connect to public Wi-Fi networks to avoid connecting to a fake network.
