Correct : B

Wireshark is a widely used network protocol analyzer that supports various capture file formats, including those generated by tcpdump.

The .pcap extension is a standard format for packet capture files and is fully supported by Wireshark.

The file extension or the inclusion of characters such as '-' in the file name does not impact Wireshark's ability to open and read the file.

When the engineer opens the sandboxmatware2022-12-22.pcaps file in Wireshark, the tool will read the packet capture data, allowing for detailed analysis of network traffic.

The Cuckoo sandbox report shows the analysis results of a file named 'VirusShare_fc1937c1aa536b3744ebfb1716fd5f4d'.

The file type is identified as a PE32 executable for MS Windows.

The 'Yara' section indicates that the file contains shellcode, which matches specific shellcode byte patterns.

Shellcode typically indicates that the file will execute a payload, often used to open a command interpreter or execute commands directly.

Additionally, the antivirus result shows that the file was identified as containing a trojan (Trojan.Generic.7654828), which is consistent with behaviors such as opening a command interpreter for malicious purposes.

The security scenario involves protecting the company from known issues that trigger adware and addressing a recent incident that could harm the system.

This scenario involves identifying vulnerabilities (weaknesses in the system that can be exploited) and threats (potential harm that can exploit these vulnerabilities).

A vulnerability is an inherent flaw in the system, while a threat is an event or condition that has the potential to exploit the vulnerability.

The security engineer needs to assess both the vulnerabilities present and the threats that could exploit these vulnerabilities to implement effective protection measures.

The regular expression provided is: .\.(pd][Oo][Cc)|[Xx][LI][Ss]|[Pp][Pp][Tt]) HTTP/1 .[01]

This regular expression is designed to match file extensions for Word (.doc), Excel (.xls), and PowerPoint (.ppt) files in HTTP network sessions.

The regular expression uses character classes and alternatives to match different case variations of these file extensions.

The part .\.(pd][Oo][Cc)|[Xx][LI][Ss]|[Pp][Pp][Tt]) matches the file extensions, and HTTP/1 .[01] ensures that the match is in the context of HTTP version 1.0 or 1.1.

Correct : A

TCP injection is an attack where the attacker sends crafted packets into an existing TCP session. These packets appear to be part of the session.

The presence of many SYN packets with the same sequence number, source, and destination IP but different payloads indicates that an attacker might be injecting packets into the session.

This method can be used to disrupt communication, inject malicious commands, or manipulate the data being transmitted.
