Shodan : title:"KNX visualisering" OR https://www.shodan.io/search?query=title%3A%22KNX+visualisering%22 ZoomEye : "KNX visualisering" OR https://www.zoomeye.ai/searchResult?q=IktOWCB2aXN1YWxpc2VyaW5nIg%3D%3D Fofa : ("KNX visualisering") && icon_hash=="2019991370" OR https://en.fofa.info/result?qbase64=KCJLTlggdmlzdWFsaXNlcmluZyIpICYmIGljb25faGFzaD09IjIwMTk5OTEzNzAi Step 2 : We Found pincode panel and they dont have RateLimit so attacker can brute force it using tools like BrupSuite. The attacker can try several numbers to know what the length of the number is for that panel, for example, one panel is 4 digits or another panel is 6 digits. Notic : Most panels Dont need authentication Example : Attacker used the dorks and founded this IP 62.163.74.206 after that attacker use the Burp Suite to brute force it .
