Dev Star provides detailed device insights, including device make, operating system, and type. Dive deep into your network information with access to unique identifiers like UDID and IDFA, empowering you with the knowledge to safeguard your digital identity. 3.Host Scanner Stay one step ahead with our Host Scanner features. Uncover vulnerabilities and potential threats by scanning hosts on your network. Host scanning helps you detect vulnerabilities in a host that may be picked out for attack. Vulnerability scanning is performed to identify potential weaknesses. 4. Network Service Discovery & Registration 5. PING Ping is used to test the reachability of a host on an Internet Protocol (IP) network. Ping works by sending an Internet Control Message Protocol (ICMP) Echo Request to a specified interface on the network and waiting for a reply. When a ping command is issued, a ping signal is sent to a specified address and it responds by sending an echo reply packet. 6. Port Scan An application can send traffic and listen on a particular port. The combination of an IP address and a port enables routing devices and the endpoint to ensure that traffic reaches the intended application. A port scan can provide a wealth of information about a target system. In addition to identifying if a system is online and which ports are open, port scanners can also identify the applications listening to particular ports and the operating system of the host. 7. Reverse/DNS Lookup - Find all DNS records for a domain name with this online tool. The DNS records include but are not limited to A, AAAA, CNAME, MX, NS, PTR, SRV, SOA, TXT, CAA, DS, and DNSKEY. - Performing a reverse DNS lookup allows users to find the hostname of an IP address. 8. Bluetooth Scan and Advertiser - Send advertising packets (PDUs) to broadcast data, and to allow other devices (scanners) to find & connect to them. - Searches the local area for Bluetooth-enabled devices & requests some information about each one 9. Sensor Data Accelerometer, Gyroscope, Magnetometer 10. GPS 11. NFC - Tag Read, Ndef Write, Ndef Write Lock
