Network devices such as modems and routers can be attacked by cybercriminals and used to steal passwords, bank accounts, card numbers credit and divert the connection of domestic users to a malicious server, even if your computer is clean and protected with a good anti-malware, according to a study by Fabio Assolini presented recently.
To protect networks residential, senior analyst at Kaspersky Lab, developed a list of ten tips to keep them safe devices and prevent such attacks:
1 – Change the default password
Routers and modems usually come from the factory with default passwords. Even when the internet provider makes installing the unit at home or in the company, the default password to access the configuration panel is held, something like “admin” or “password”. “We recommend changing this password because it is too simple for a criminal conduct a web attack, access the modem or router panel and change the settings,” says Assolini
Walkthrough:. you must first find the port where your modem or router is installed. Open Command Prompt in the Windows Start bar and type “ipconfig”. Search for the address of “Default Gateway”, which begins with “192.168 …”. Then enter this address in the browser bar, log on the panel with the default credentials and look for the option to change the password.
2 – Set a strong password and encryption on the device
When you change the default password of the device is important to choose one that is strong. Avoid using words, dates or names that appear in a dictionary. Create a password mixing numbers, letters and symbols, with at least eight characters. Remember:.. How much easier the password, the more likely a neighbor or someone malicious connect to your device
Another important tip is to choose the correct encryption WiFi network The safest standard is currently the WPA2-PSK. Avoid WPA or WEP, which are old standards and can be easily overcome
3. – Never enter your router’s password on a webpage
Cybercriminals can attack your router or modem and change your settings via a simple web attack. Just visit a popular website that has been compromised.
If any site request the password to your router or modem, never reveal your login. Under these conditions, just click cancel the attack will be neutralized
4. – Change the DNS of your Internet service provider
Unfortunately, there have been several incidents malicious redirects involving the legitimate DNS servers of Internet providers. In these attacks, cybercriminals hijack the provider nameservers and use them for a period of time to direct users to fake websites of banks or installing malware. The easiest way to prevent this attack is to use a different DNS server of your provider. There are more reliable alternative DNS services, such as Google DNS (8.8.8.8) and OpenDNS (208.67.222.222)
This amendment can be accomplished in two ways:
- Set the connection properties to the internet each connected device
- Change your modem or router options. . In this case, look in the DNS option Control Panel, delete the nameservers of your provider and enter a more reliable address
5 – Change the default ports
Modems and routers are usually installed on standard doors, the most common are 192.168.0.1; 192.168.1.1 or 192.168.1.100. Avoid using these ports. You can configure your network to use different ports, which makes it difficult for a brute force attack against the device
6 -. Update your router’s firmware or modem
Few people remember to update the firmware of network devices. These updates fix security flaws. Generally, the manufacturer’s website you can download for free, depending on the device model. But to do so, you must very carefully because a wrong update can cause the device to stop functioning. If you are unsure how to do, do not! And ask for help from your internet provider or a trusted technician
7 -. Turn off unnecessary services and configure properly
Your router or modem feature Remote Access Services or other technologies that are rarely used and can be disabled for your safety. They are:
- Remote Management and other services: the configuration panel of your modem or router can almost always be accessed only locally ( LAN), but this does not always occur. Some manufacturers offer a remote management function. Ensure that the panel is not accessible via the web. In most cases, to disable this feature, you should seek specific option in the settings by typing the address 0.0.0.0. . It is also prudent to disable the SSH or Telnet protocols and UPnP services (Universal Plug and Play) and DLNA (Digital Living Network Alliance)
- Broadcast SSID: as a rule, a router or modem transmit their ID publicly, leaving your network visible. This can be changed in the configuration panel. By disabling the SSID broadcast, however, your network will no longer be visible, and you must provide the name of the network whenever a new device attempts to connect to it.
8 – Attention to HTTPS
When a modem or router are attacked and other DNS servers are configured on the devices, it is common for malicious redirects are made to fake pages that do not have the security lock or the links to view the “HTTPS”, indicating the absence of a secure connection (SSL).
Never sign a page of these and avoid using banking sites or shopping online until the problem is resolved and a padlock appears in the
9. – Use a good anti-malware program
The modern anti-malware programs usually bring extra protections for unreliable connections even the extremely dangerous and vulnerable Wi-Fi networks. Kaspersky Internet Security has a module that protects these links problematic Wi-Fi networks and SafeMoney (Secure Payment), which guarantees secure access to banking and online shopping sites, preventing MITM attacks (Man-in-the-middle ), which occur when the cybercriminal performs malicious redirects.
10 – If any of this fix
If even with all these precautions are detected abnormal behavior while browsing, such as links to fake pages, ask your supplier a change of equipment. The operator has a duty to replace the equipment if the problem persists.
