FragAttacks is commonly known as wi-fi attacks that penetration and intrusion acts target wireless networks which poses to serious threats. Wireless networks attacks aim is to capture information sent across network with the traffic of information. There are several ways how hackers access to a public wi-fi network and infiltrate connected devices to steal data.
The most common practice that hackers use is sniffing which allows hackers to hijack any packet of data that is being transmitted between a device and a router. Hackers many times leaves the wi-fi open to all users, when some one connects device to open wi-fi their devices IP address and registered router, hackers first intercepts traffic by using some tools.
There are basically three different types of wireless networks – WAN, LAN and PAN: Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals typically provided and maintained by specific mobile phone (cellular) service providers.
5 Tips to Keep Your Data Safe on Public Wi-Fi
- Verify the Network: Configure and Turn off Sharing. Remember that hackers are very clever, so its better to surf and play smart
- Use a VPN. A VPN (Virtual Private Network) is the most secure option to surf on public networks
- Use HTTPS
- Keep the Firewall Enabled
- Use Antivirus
FragAttacks full details
FragAttacks of vulnerabilities in Wi-Fi products have likely left users open to attacks as millions of devices are impacted, according to cybersecurity expert. A number of vulnerabilities in a majority of Wi-Fi products have likely left users open to attacks and millions of devices are believed to be impacted.
The flaws named FragAttacks were discovered by cybersecurity expert, a postdoctoral researcher at the New York University of Abu Dhabi. Experts previously highlighted Kracattacks, which were a serious flaw in WPA2, a protocol used to secure protected Wi-Fi networks.
FragAttacks are fragmentation and aggregation attacks, allow an attacker who is within range of one’s Wi-Fi device to steal user information, including sensitive information such as passwords. According to the researcher, while three are design flaws in the Wi-Fi standard, several other vulnerabilities were discovered that are caused by widespread programming mistakes in Wi-Fi products.
Experts states that almost every Wi-Fi product is affected by at least one vulnerability and that most products are affected by several vulnerabilities. Also notes that while the design or hardware level flaws are much harder to exploit, the programming mistakes are quite easy to abuse. In experiments on more than 75 devices, all of them were vulnerable to one or more of the discovered attacks.
Types of Wi-fi Attacks
- Rogue Wireless Devices
- Peer-to-peer Attacks
- Encryption Cracking
- Authentication Attacks
- MAC Spoofing
- Management Interface Exploits
- Wireless Hijacking Etc.
How to check whether network is secure?
- Simple method
- Advanced method
- Change the wireless network’s default name
- Use encryption
- Choose a strong password
- Check that your device does not auto-connect to Wi-Fi signals
- Update the router
Signs your router’s been hacked
- Your router login is no longer effective.
- Foreign IP addresses are listed on your network.
- You’re receiving ransomware and fake antivirus messages.
- Software installations are taking place without your permission.
- Your internet service provider (ISP) reaches out.
