What Type Of Attack Do Hackers Use Involving Free Wifi

Man In The Middle Attacks

WiFi Hacking using Evil Twin Attacks |WiFi Hacking using Evil Twin Attacks and Captive Portals| 2020

We mentioned this particular attack vector in our Cybersecurity 101 blog. When anyone can set up an Internet connection without authentication, the most basic hacker can set herself up between you and the server. Then shes sitting pretty with her latte watching every bit of info everyone else in the cafe sends and receives. Network snooping and sniffing are disturbingly simple man in the middle attacks to pull off on free networks. So if youre using free WiFi, pretend like your high school principal is staring over your shoulder the entire time, watching and recording everything you do.

Should I Enable Ssl Inspection

SSL inspection allows you to inspect traffic to and from encrypted websites. Since most websites now secure the connection between the site and browser, this traffic will be invisible unless you enable SSL inspection. Malicious websites often have SSL certificates and will pose a serious threat if traffic is not inspected.

The Internet Of Things

Connected devices are one of the latest new potential entry points. If you have connected items, you may be opening your company up to cyberattacks. The problem is that many IoT devices have poor communication implementation between the device and supporting cloud service. This can make many devices vulnerable, in some cases allowing attackers to take over your IoT devices for further attacks or even spy on your business – where think cameras are connected.

Not only is privacy a key concern, but people may be able to hijack your devices and take control of what those devices control.

It is predicted that 50 billion devices will be connected to the internet by 2020, so it is essential that we make sure they, and our businesses, are protected.

Here’s Everything You Need To Know About Today’s Massive Wi

A huge vulnerability in Wi-Fi that fundamentally breaks the security we use to protect our wireless networks has just been exposed.

The exploit, revealed on Monday, breaches a newly found vulnerability in WPA2, the security protocol used to safeguard all modern Wi-Fi networks, and researchers say it could violate virtually any Wi-Fi network previously thought to be secure.

“The attack works against all modern protected Wi-Fi networks,” explains the security researcher who discovered the vulnerability, Mathy Vanhoef from Belgium’s KU Leuven university.

“The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected.”

By taking advantage of the vulnerability in what is called a key reinstallation attack , a hacker could read information supposed to be encrypted on a Wi-Fi network, intercepting potentially sensitive information like credit card numbers, passwords, photos, and messages.

In the worst case, Vanhoef says, it could be possible for someone to use KRACKs to inject and manipulate data on a compromised Wi-Fi network, hijacking devices to inject ransomware or other malware onto systems.

“Wow. Everyone needs to be afraid,” researcher Robert Graham of Errata Security, who wasn’t involved with the discovery, wrote in a blog post.

“Essentially, to guarantee security, a key should only be installed and used once,” Vanhoef explains.

Top Tips For Public Wi

  • Make sure any website you are using has a secure HTTPS connection. The full web address should begin with HTTPS rather than HTTP, which isnt encrypted. You can tell if a website uses HTTPS if the browser displays a padlock next to the URL.
  • Avoid using password protected websites that contain sensitive information, like online banking, email and social media. If you do want to access these services, it is better to use your mobile phone network instead of public Wi-Fi.
  • Be aware of rogue hotspots, often with names very similar to authentic public Wi-Fi networks. Take the time to check that you are connecting to the legitimate network. If in doubt, ask an employee at the location to verify the correct name of the Wi-Fi point.
  • Set your mobile device to ‘ask’ before it connects to a Wi-Fi network, rather than automatically connecting to an available network. Hackers can easily spoof a Wi-Fi network’s broadcast name. Check your settings to make sure the device asks first, allowing you to make a decision about whether it’s safe to connect or not.
  • to reduce the risk of being infectd by viruses or malware when using unsecured public Wi-Fi.
  • Consider using a virtual private network if you regularly work with confidential information whilst on the move. VPN software protects you by encrypting all your network traffic.

Be vigilant. Know who’s around you. Sometimes, paranoia can help. If you’re not sure of those around you, don’t go on anything private.

Don’t underestimate the importance of what you’re filling out or reading either: medical information can be useful to identity thieves, for example. If it’s a document or webpage you wouldn’t want anybody else seeing, take precautions to stop that from happening.

Another option is to purchase a privacy screen these limit what people see on your screen.

Use Of Default Ssids And Passwords

WIFi access points are shipped with a default SSID and password which need to be changed, but all too often, those default passwords are left in place. That makes it easy for an attacker to log in and take control of the router, change settings or firmware, load malicious scripts, or even change the DNS server so that all traffic is directed to an IP owned by the attacker. Default passwords must be changed to prevent anyone within range of the signal from connecting and sniffing traffic.

If wireless controllers are used to manage WiFi access points via web interfaces, make sure the default passwords are also changed. These default passwords can be easily found online and can be used to attack wireless networks.

Distributed Denial Of Service Attack

This hacking terminology is highly common among hackers and is a major concern for website owners and developers. A DDoS attack is carried out with the aid of zombies or botnets controlled by black hats. By programming the botnets, the black hats command them to send data packets to the targeted web server from multiple systems. This floods the target server thereby slowing down or even crashing and shutting down the server thereby disrupting any activity. All the while the user of the server is oblivious to the attack.

Some of the most notoriously known attacks discovered lately were the Rio Olympics DDoS which lasted for months, Russian banks Sberbank and Alfabank which were attacked by a botnet consisting of at least 24,000 computers located in over 30 countries, and the US presidential elections campaign attacks.

Are Packet Sniffing And Spoofing Both Same

Most of you may not know that spoofing and sniffing are different. Mainly these two phrases are used interchangeably among businesses. But both are entirely different from each other because sniffing has the direct involvement of the hackers. Because here, hackers intercept the network to obstruct traffic and gather unencrypted data.

Whereas in spoofing, there is no direct involvement other than the man in the middle attack. In this method, the hacker impersonates the other person to execute the same malicious goal. They intercept the traffic having packets and gain access to the targeted or sensitive data of the organization.

A free Wi-Fi connection in a public space can seem like a lifesaver when youre on the go. But if you decide to use public Wi-Fi, just be aware that you could be making yourself an easy target for hackers and putting your information and more at risk.

Whats The Best Way To Keep My Information Safe

The good news is that you definitely dont have to give up public Wi-Fi completely. Kirkham suggests several ways to keep your information as safe as possible while browsing.

The best defense is using a virtual private network or VPN, Kirkham says. A VPN creates a secure connection between your device and the internet by using an encrypted and secure connection to the VPN server. It protects your data by encrypting it so malicious actors cannot tell what you are doing online, he says.

Businesses often install VPNs on the devices their employees use while working outside the office, but theyre available to individuals as well. You can simply download one from your usual app store and install it on your personal device. Heres how a VPN can keep your information safe on public Wi-Fi.

    There are network security practices that can help users avoid the risks associated with wardriving.

  • Turn off the Wi-Fi network when not in use: Turning off a Wi-Fi router when nobody is home or when it is not being used will prevent the network from being accessed by hackers.
  • Change the routers default factory password: Wi-Fi router manufacturers typically assign a standard username and password, which helps users quickly set up and configure the device. These default credentials may be known to hackers, so it is vital to change the login to a unique name and password combination.
  • Use encryption: Wi-Fi routers can be set only to allow access when the correct password is entered. This uses encryption standards like Wi-Fi Protected Access
  • Install a firewall: Firewalls are crucial to protecting networks because they monitor access requests and block any activity from unapproved sources. Users should use firewalls to add an extra layer of security to their standard Wi-Fi setup.

    Examples Of Wifi Network Attacks

    Attacks on wireless networks are not just theoretical. Listed below are some examples of common wireless networks attacks that have resulted in the installation of malware or theft of sensitive information. These latest wireless security attacks could easily have been prevented had appropriate security controls been implemented.

    Legal And Illegal Use Of Packet Sniffers

    There can be legal and illegal use of packet sniffers by the IT professional. When IT professionals and networking experts use packet sniffers to analyze traffic and security analysis, its called legal packet sniffers. And by using it, they can find the troubleshooting network issue of the organization as well.

    It can also be used for the information security context. However, this tool can also be misused if the wrong person gets such tactics. Sniffing tools can be illegally used for stealing the data of customers. It can discover the passwords and bank details of the user as well. The hackers can also execute other malicious activity using sniffers.

    Some packet sniffer tools are BetterCAP, WinDump, Wireshark, and Ettercap. Most people do not know sniffer attacks can cause them if they use an unsecured WiFi connection. By using such tools, the hackers can execute DDoS or MitM attacks as well. Hence, these factors must be considered because they can be a threat to businesses.
