The term free Wi-Fi is happy for everyone. But the reality is that you may get more trouble than you think. There really is no security when it comes to privacy or data, the major problem with public Wi-Fi. Public Wi-Fi is public as the name implies pun intended and accessible to all. And now everyone can hack you because you're on the same network as them.
Note: If your computer is loaded with proprietary information (or financial data). It's probably best to completely avoid public Wi-Fi. The risk linked to public Wi-Fi networks is as follows.
1. Rogue Wi-Fi networks
You can get fooled into using an attacker's or a blackhat hacker's malicious Wi-Fi network. It can have a trustworthy name such as "Free Wi-Fi" or GUEST-WIFI. When you are in a hotel, everyone may call Wi-Fi or free Wi-Fi as a guest. They may have malware and sniffers sent to your computer which compromises your data and the data of your business.
2. Man-in-the-middle attacks
Man in the middle attacks is common as you know, and they are difficult to recognize because they are passive in nature. A man in the middle (MITM) attack is a general phrase for the attacker when he positions himself in an interaction between a user and an application — to eavesdrop or to unmask a group, making it appear that regular information exchange is taking place.
The objective of an attack is to rob personal information like log-in credentials, account information, and credit card numbers. Targets typically include users of financial applications, SaaS companies, e-commerce sites, and other websites that require login.
3. Malware over unsecured Wi-Fi
Most hackers would send malware to the network to build backdoors and steal your details. For hackers, there are several ways to do this because people don't use Wi-Fi and their computers with the requisite protections. Most don't even buy an Antivirus. That's an awful idea, BTW!!
4. Snooping and sniffing
This attack is usually used together with a man in the middle attack. However, this doesn't have to be the case. Especially when the victim uses HTTP websites. You don't even have to hack MITM, you 're clear to every network sniffer.
Many people do not know about the risks of not using https websites. Even the hacking world only uses https to safeguard its readers. No login as such is available for readers, but why risk it?
5. Targeting companies
Most hackers seek hacking businesses via a compromised computer to gain access to the company 's network. Hackers are always looking for apps that can be hacked easily. You can easily be compromised by using public Wi-Fi. If you don't want your job to be lost because of negligence. I 'd recommend to completely avoid public Wi-Fi networks.
6. Malicious attacks through ad hoc networks
Ad hocs are peer-to-peer networks allowing users to directly connect two or more computers. If a staff's system is disrupted by a public Wi-Fi network, their devices can be placed on a new network so that hackers can manipulate and exploit other computers on the network. You don't want to happen that kind of thing.
7. Password and username vulnerability.
Due to the presence of sensitive information, such as the cookies or passwords, which can be accessed by anyone, is shared on the network. Will you really want to keep this network open? I don't, okay. This is why I honestly feel that there must not be public Wi-Fi at all.
8. Exposure to virus worm attacks.
If you've read my posts, you know how easy it is for hackers to break into your network. If you're not patient, not only can your system be infected with a virus. Your machine will spread the virus with the possibility that you will be responsible for it.
9. Phishing campaigns
Across my previous posts, you have read how easy it is to conduct a phishing attack on the same Wi-Fi network. The bank and other financial details can be easily obtained by a hacker if you are compromised in a phishing campaign.
10. Crypto miners
Owing to the growing need for cryptocurrencies, many hackers have begun mining bitcoin. Most devices have been hacked and used as a miner to mine data and get crypto coins. Such miners run in the background and use your machine resources to process your results. Congratulations, your system has just become a hacker's slave.
Ads are the most widely used approach to earn money. Legally as well as illegally. Most hackers have adware and advertising on the network that, when clicked, give money to the hacker. Most public Wi-Fis are corrupted in the same way as the person who signs up ends up stitching a lot of ads on the network. Ignore outdoor Wi-Fi unless you like to access.
Botnets are zombie networks or a collection of infected devices that are used to attack DDoS companies and servers around the world. That is particularly unethical and will result in a lot of fines. Guess who's going to be watched when this attack occurs. A lot of hackers can switch networks so that instead of their network, the trace can lead back to you. You may be running a botnet through your system without even realizing it.
Increased cybersecurity threats over the last decade have skyrocketed to unprecedented proportions. 1 in 3 people either have their email hacked or infected their data through viruses or malware. If you think about that, that's a lot of people. Ok, I hope you liked this article. Make sure you share and follow this blog.
