A new IoT Botnet is Spreading over HTTP Port 81 and Exploit the Vulnerability in Security Cameras

[jpshare]A New IoT  Botnet Discovered which scanning the entire Internet and Exploit the vulnerability in many Security Cameras and 50k live scanner IPs daily .

This IoT findings revealed that,it is Very Much Active in the internet and improve its live scanning rapidly.

A Month Before Researcher Kim Finding the Vulnerability in OEM cameras involved more than 1,250 different camera manufacturers and estimate that more than 185,000 devices Vulnerable to Attack by  RCE ( Remote Code Execution) attack.

According to Qihoo 360 Net sec Research Lab  ,IoT Botnet  payload used to scan the port and change the post Number  81 and this syn scan has actually borrowed from Mirai Botnet .

Port 81 is an Internet socket port that the Internet Protocol Suite uses to establish host-to-host communications These ports keep Internet connections organized and separated, and are set by the Transmission Control Protocol, or TCP. Some ports may also be set by the User Datagram Protocol, or UDP.

This botnet gets halfway code, for example, port scanning module from the Mirai, yet it is totally not quite the same as mirai as far as infect chain, C2 correspondence convention, assault module criteria.

Botnet Spreading over HTTP Port 81:

Once Attackers start Scanning the Internet for GoAhead with all the vulnerable Cameras by using post number 81 and once attacker Find the vulnerable host, they will Exploit an Attack using the botnet payload to the security Cameras.

Exact Scan was Started on 16-04-2017 by Qihoo 360 Net sec Research Lab,  one day after, the number of scanning sessions increased to 400% to 700%, the number of unique scanner had 4000% to 6000% increments. On 2017-04-22, the number of unique scan source had passed over 57,000.

Payload scan:

Finding Under PoC ,The payload is delivered after a successful port 81 scan and verification process,Victim downloads and executes the script .

Once Execute the Script, the connection with the control server, and that is the end of the infection phase, and the device is ready to launch attack.
