  • Encryption: 64/128-bit WEP, WPA/WPA2, WPA-PSK/WPA2-PSK
  • Storage: EZVIZ cloud and/or MicroSD
• Abus PPIC32020
  • Encryption: AES 128bit, WPA/WPA2-PSK
  • Storage: MicroSD

Apps

• Kasa Smartphone application (IOS or Android)
• Ezviz Smartphone application (IOS or Android)
• ABUS App2Cam Plus Smartphone application (IOS or Android)

Description

A penetration test can be divided into several stages:

• Planning

Working with a costumer to absolutely outline and report evaluation objectives, scope, and policies of engagement.

• Gathering Information

Collecting and examing key data approximately the software and its infrastructure.

• Discovering Vulnerabilities

Find current vulnerabilities and identify any potential security weaknesses that could allow an outside attacker to gain access to the environment.

• Exploitation

The pentester tries to establish a connection with the target and exploit the vulnerabilities found in the previous phase.

• Reporting

Providing a complete documentation with deep evaluation and suggestions on the way to mitigate the found vulnerabilities.

Planning

You need to set up the camera at home together with your phone app and allow it to connect with the identical WiFi that your smartphone uses. To find out the IP Address of the camera you need to install scanning tools, that can gain access to devices in your subnet.

Scanning

First, an Nmap scan is performed. Doing so will give you important information to find the vulnerability.

Target Specification:

$sudo nmap <target IP>       Scan a single IP

Enables OS detection, version detection, script scanning, and traceroute:

$sudo nmap -sV -A <target IP>

Scan TCP/UDP Ports:

$sudo nmap <target IP> -sT    TCP connect port scan (Default without root privilege).
$sudo nmap <target IP> -sU    UDP port scan.

Host Discovery and Port Scan:

$sudo nmap <target IP> -sn         Disable port scanning. Host discovery only.
$sudo nmap <target IP> -Pn        Disable host discovery. Port scan only. (If the host is down)

Port Specification:

$sudo nmap <target IP> -p-          Scan all ports

OS Detection:

$sudo nmap <target IP> -O          Remote OS detection using TCP/IP

It is possible to use a set of scripts from the /usr/share/nmap/scripts/ directory:

$nmap -sV --script $SCRIPT <target IP>
