Which action matches the weaponization step of the Cyber Kill Chain Model?
The weaponization step in the Cyber Kill Chain Model involves the creation or use of a specific weapon (malware, exploit) designed to leverage a vulnerability.
This phase follows the reconnaissance phase where the attacker gathers information and precedes the delivery phase where the weapon is delivered to the target.
Developing specific malware to exploit a vulnerable server is a precise example of weaponization.

The SOC team detected an ongoing port scan. After investigation, the team concluded that the scan was targeting the company servers. According to the Cyber Kill Chain model, which step must be assigned to this type of event?
An engineer must investigate suspicious connections. Data has been gathered using a tcpdump command on a Linux device and saved as sandboxmatware2022-12-22.pcaps file. The engineer is trying to open the tcpdump in the Wireshark tool. What is the expected result?
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.

A company encountered a breach on its web servers using IIS 7 5 Dunng the investigation, an engineer discovered that an attacker read and altered the data on a secure communication using TLS 1 2 and intercepted sensitive information by downgrading a connection to export-grade cryptography. The engineer must mitigate similar incidents in the future and ensure that clients and servers always negotiate with the most secure protocol versions and cryptographic parameters. Which action does the engineer recommend?
Upgrading to TLS v1.3 is recommended because it eliminates outdated cryptographic functions and reduces the risk of downgrade attacks, which can occur when attackers force connections to use weaker encryption. TLS v1.3 only supports secure cipher suites and algorithms, enhancing the security of communications.
