It is too easy to remotely steal ADSL accounts

Most of the ADSL modem's built-in routing functions, but its random software does not support using this function in the PPPoE virtual dial-up access mode, so many friends want to be able to connect to the Internet with multiple computers, an external router is used, but this leaves the hacker with an opportunity.

Hacker confession:

If you use a vroadsl to share ADSL Internet access, the most common problem is that you have not modified the configuration password of the vro. A general router will have a default configuration password when leaving the factory. Only by knowing the password can you configure the vro. Many users have not changed this password after configuring their own vrouters. As a result, some attackers on the internet can control the vro and steal the user's ADSL account.

Search for Attack Targets

Scan the user's IP address segment on the ADSL Network to obtain the list of hosts with port 80 enabled. If you are using ADSL to access the Internet, first dial your own ADSL, and then run the ipconfig command to view your IP address.

Generally, most users access the Internet through ADSL in Beijing are 61. 49 .*.*. After obtaining your own IP segment, you can find a good port scanning tool. There are many port scanning tools, including multithreading, small size, and fast SuperScan. We will use it as a demonstration tool here.

Remote theft of ADSL accounts

Generally, we enter the first IP address in the starting address, that is, 61. 49. *. 1. The ending IP address is automatically displayed as 61. 49. *. 254. For the IP addresses in this segment, that is, the first three IP addresses of the same IP addresses as their own IP addresses, you can set the data to be shorter during scanning, for other CIDR blocks, you must set a larger value.
