Figure 1. Phishing Cycle Definition of Phishing Terms Phishing is the general term for soliciting users to divulge personal or account information through deceptive techniques. This deception may take the form of E-mail messages, telephone calls, or even faxed messages. Generic phishing is not targeted at a specific user or group of users, but rather the phisher uses pre-compiled lists of E-mail addresses either purchased or created.

Serving as a solution to the growing demand for increased need to keep people connected, wireless networks have come to play a key and indispensable role in corporate networks. These networks, in turn, need effective monitoring and the professionals who manage them must understand the risks and map out the existing vulnerabilities. The procedures for detecting safety flaws can be automated through tools or made by a qualified professional who will manually validate each critical point, this being the Pentester.
This work aims to demonstrate the steps of performing an intrusion test in order to obtain critical data such as Network Administrator access. By using intrusion testing, network administrators can identify vulnerabilities and thus propose improvements and fixes to avoid being the target of some invasion by digital criminals.
The reverse engineering technique can be applied in several areas, not only in software, because its purpose is to present to the one who is carrying out the process, the final result in its construction. Applied in software, such as malware analysis, reverse engineering is the process that involves decompiling the binary code into an assembly language, or even the language in which the program was written.
This article will deal exclusively with reverse engineering and tampering with code developed on the. NET platform. Like other globally known languages,. NET is based on a virtual machine platform, that is, although it is compiled, the code is interpreted based on a framework where it is possible to use several programming languages like VB. NET, C. NET, F.
NET, and so on. Thus, the collection and analysis of digital evidence for both legal and commercial purposes requires a professional trained for such work, which is a Forensic Analyst or Forensic Expert, or Expert Witness to court of law. The following study shows some procedures present in the Computer Forensics Expertise cycle; preservation practices, collection, analysis and completion are elucidated in the text. Free tools are also included and I will cover other general aspects surrounding the subject.
As such, the presentation is not overly technical in scope, but covers instead what penetration testing is, what benefits stakeholders in a secure system receive from a test, and how Powershell can used to conduce some steps of penetration testing. The presentation goes into an example procedure for penetration testing, explain some steps Reconnaissance, Scanning, Gaining Access, Maintaining Access, Covering Tracks and Reporting.
These represent the steps that attackers use in common attacks. Finally, this presentation also briefly discusses some techniques involving non-conventional devices such as Smartphone bootable and the dangers of an unprepared team. As such, the presentation does not have the objective of exhausting the subject. The presentation passes to an example forensic collection procedure using the Toolbox tool of the Paladin 7 distribution, after the Autopsy tool is used to analyze the Windows 10 Operating System.
These procedures represent the steps that the Forensic Expert addresses to answer the proposed technical questions.
Finally, this presentation also briefly discusses some free tools for computational forensics.
