Given the Nmap scan results showing an open HTTP service on port 8080 running Microsoft IIS 9.0, the next logical step for the penetration tester would be to further explore the web server. Nikto is a web server scanner that can identify known vulnerabilities, configuration issues, and other security problems.
Using the command nikto
-host http://10.22.2.2
will initiate a scan against the HTTP service on the target server, helping the tester to identify potential weaknesses that could be exploited.

Since it doesn't indicate company owned devices, sending a text to download an application is best. And it says social-engineering so a spoofed text falls under that area.

IoT devices are often shipped with default passwords, which are easily discoverable and widely known. Many users fail to change these default credentials, leaving the devices vulnerable to unauthorized access. This issue is one of the most common vulnerabilities associated with IoT devices connected directly to the internet.
Attackers can exploit these default passwords to gain control over the devices, potentially leading to a range of malicious activities, including the recruitment of the devices into botnets for Distributed Denial of Service (DDoS) attacks, data breaches, or other cybercriminal activities.

The attacker is sequentially changing the serviceID parameter in the URL, likely in an attempt to access objects that they are not authorized to see. This is indicative of an attempt to exploit an Insecure Direct Object Reference (IDOR) vulnerability, where unauthorized access to objects can occur by manipulating input or changing parameters in the URL.
An insecure direct object reference (IDOR) vulnerability occurs when an application exposes a reference to an internal object, such as a file, directory, database record, or key, without any proper authorization or validation mechanism. This allows an attacker to manipulate the reference and access other objects that they are not authorized to access. In this case, the attacker was trying to exploit the IDOR vulnerability in the servicestatus.php script, which accepts a serviceID parameter that directly references a service object. By changing the value of the serviceID parameter, the attacker could access different services that they were not supposed to see.
